29 longer include a "manifest" to prevent them failing at import time in some
30 embedded situations.
31
Benjamin Petersona7b09762011-10-15 13:43:21 -040032- Issue #13186: Fix __delitem__ on old-style instances when invoked through

Mark Dickinsondbbed042011-09-19 16:38:08 +010041- Issue #12973: Fix overflow checks that invoked undefined behaviour in
42 int.__pow__. These overflow checks were causing int.__pow__ to produce

Mark Dickinsona96b0d12011-09-24 09:01:16 +010044 compiler optimizing the check away. Also fix similar overflow checks
45 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

60 deallocator calls one of the methods on the type (e.g. when subclassing
61 IOBase). Diagnosis and patch by Davide Rizzo.

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

273
Ned Deily87e82bb2011-06-28 19:52:59 -0700274- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
275 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
276 interpreter process. This could cause failures in non-Distutils subprocesses
277 and was unreliable since tests or user programs could modify the interpreter
278 environment after Distutils set it. Instead, have Distutils set the the
279 deployment target only in the environment of each build subprocess. It is
280 still possible to globally override the default by setting
281 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
282 greater or equal to the default value, the value with which the interpreter
283 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400311- sys.setcheckinterval() now updates the current ticker count as well as
312 updating the check interval, so if the user decreases the check interval,
313 the ticker doesn't have to wind down to zero from the old starting point
314 before the new interval takes effect. And if the user increases the
315 interval, it makes sure the new limit takes effect right away rather have an
316 early task switch before recognizing the new interval.

1189 received. Now sendall() properly calls signal handlers if necessary,
1190 and retries sending if these returned successfully, including on sockets
1191 with a timeout.

Antoine Pitrouf7f390a2010-09-14 14:37:18 +00001204- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
1205 SSLSocket.sendto() to match the corresponding socket methods. Also,
1206 fix various SSLSocket methods to raise socket.error rather than an
1207 unhelpful TypeError when called on an unconnected socket. Original patch
1208 by Andrew Bennetts.

1217
Raymond Hettinger20397532010-09-12 02:11:45 +00001218- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1219 This prevents user-created self-referencing ordered dictionaries from
1220 becoming permanently uncollectable GC garbage. The downside is that
1221 removing __del__ means that the internal doubly-linked list has to wait for
1222 GC collection rather than freeing memory immediately when the refcnt drops
1223 to zero.
1224

1231 to fetch the original errno, or to filter timeout errors. Now the
1232 original error is re-raised.

1253
R. David Murray7c4bf552010-08-25 01:45:57 +00001254- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1255 character years even if the message contains RFC822 two character years.
1256

1276
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001277- Issue #9626: the view methods for collections.OrderedDict() were returning

1286 and a BadZipfile error is raised if it doesn't match (as used to be the
1287 case in Python 2.5 and earlier).
1288
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001289- Issue #9550: a BufferedReader could issue an additional read when the
1290 original read request had been satisfied, which could block indefinitely
1291 when the underlying raw IO channel was e.g. a socket. Report and original
1292 patch by Jason V. Miller.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002043 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2044 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2045 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2065Core and Builtins
2066-----------------
2067
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002068- Issue #7301: Add environment variable $PYTHONWARNINGS.
2069
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002070- Issue #8329: Don't return the same lists from select.select when no fds are
2071 changed.
2072
Georg Brandlfee0f442010-05-22 21:26:21 +00002073- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002074 on 64-bit machines. The shift count for either left or right shift is
2075 permitted to be up to sys.maxsize.
2076
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002077- Ensure that tokenization of identifiers is not affected by locale.
2078
Georg Brandlfee0f442010-05-22 21:26:21 +00002079- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002080
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002081- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2082
Georg Brandlfee0f442010-05-22 21:26:21 +00002083- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2084 with a non-empty format string. This is an effort to future-proof user
2085 code. If a derived class does not currently implement __format__ but later
2086 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002087 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002088 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002089
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002090- Issue #8268: Old-style classes (not just instances) now support weak

2102
Victor Stinner66644262010-03-10 22:30:19 +00002103- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002104 (SIGINT). If an error occurs while importing the site module, the error is
2105 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002106 module.

2120
Georg Brandlfee0f442010-05-22 21:26:21 +00002121- Issue #8257: The Decimal construct now accepts a float instance directly,
2122 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002123
2124 >>> Decimal(1.1)
2125 Decimal('1.100000000000000088817841970012523233890533447265625')
2126
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002127- collections.Counter() now supports a subtract() method.
2128
Georg Brandlfee0f442010-05-22 21:26:21 +00002129- The functools module now has a total_ordering() class decorator to simplify
2130 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002131
Georg Brandlfee0f442010-05-22 21:26:21 +00002132- The functools module also adds cmp_to_key() as a tool to transition old-style
2133 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002134
Georg Brandlfee0f442010-05-22 21:26:21 +00002135- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2136 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002137
Georg Brandlfee0f442010-05-22 21:26:21 +00002138- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2139 InvalidOperation instead of returning False. (Comparisons involving a quiet
2140 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2141 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002142
Georg Brandlfee0f442010-05-22 21:26:21 +00002143- Issue #2531: Comparison operations between floats and Decimal instances now
2144 return a result based on the numeric values of the operands; previously they
2145 returned an arbitrary result based on the relative ordering of id(float) and
2146 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002147
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002148- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002149 argument `-` which tells it to read files to compile from stdin. Each line is
2150 read on demand and the named file is compiled immediately. (Original patch by
2151 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002152
Georg Brandlfee0f442010-05-22 21:26:21 +00002153- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002156- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2157 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002158 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002159
Georg Brandlfee0f442010-05-22 21:26:21 +00002160- Comparisons using one of <, <=, >, >= between a complex instance and a
2161 Fractions instance now raise TypeError instead of returning True/False. This
2162 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2163 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002164

2173
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002174- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002175 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2176 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002177
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002178- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Georg Brandlfee0f442010-05-22 21:26:21 +00002219 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2220 log file to compute the next rollover time. If the log file does not exist,
2221 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002222

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002262- Issue #8300: When passing a non-integer argument to struct.pack with any
2263 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002267- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2268 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2269 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002270 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2271 inconsistent: __int__ was used for some integer codes but not for others, and
2272 the set of integer codes for which it was used differed between native packing
2273 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002485- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
2486 now also used by regrtest to run all the tests in a temporary directory. The
2487 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
2488 Xicluna who helped with the patch.

2505 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002506 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00002520- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2521 and add the additional members returned in an OSVERSIONINFOEX structure. The
2522 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002525- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2526 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2527 returning NULL. The macro now returns a statically allocated empty string
2528 instead.

2538 strings,
2539 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2540 numeric strings corresponding to subnormal values,
2541 (3) a memory leak for some values large enough to cause overflow, and
2542 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002573- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002574 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002575 Also, raise ValueError rather than TypeError when an unknown TIPC address
2576 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002580- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002581 file position when calling `truncate()`. It would previously change the file
2582 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002583 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2584
Georg Brandlba83f822010-03-14 09:50:54 +00002585- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2586 class used to represent files stored inside an archive. The new
2587 implementation is significantly faster and can be wrapped in a
2588 ``io.BufferedReader`` object for more speedups. It also solves an issue
2589 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2590 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00002599
Georg Brandlba83f822010-03-14 09:50:54 +00002600- Issue #7748: Since unicode values are supported for some metadata options in
2601 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2602 encoded string for them. This ensures that the upload and register commands
2603 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002680- The ``__complex__()`` method is now looked up on the class of instances to
2681 make it consistent with other special methods.

2685
Mark Dickinson1b34d252010-01-01 17:27:30 +00002686- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002687 DeprecationWarning when passed a float argument where an integer was expected.
2688 These functions and methods now raise TypeError instead. The majority of the
2689 effects of this change are in the extension modules, but some core functions
2690 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2691 and many unicode/str methods.

2707 internal representation of a long.

2715
Georg Brandlba83f822010-03-14 09:50:54 +00002716 These executables now work properly with the arch(1) command: ``arch -ppc

2858 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002859
Georg Brandlba83f822010-03-14 09:50:54 +00002860- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2861 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002862
Georg Brandlba83f822010-03-14 09:50:54 +00002863- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2864 1e-100 used to raise OverflowError, but now gives the requested 120
2865 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002873
Georg Brandlba83f822010-03-14 09:50:54 +00002874- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2875 decimal string that's guaranteed to round back to x under correct rounding
2876 (with round-half-to-even rounding mode). Previously it gave a string based on
2877 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2878 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2879 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002880
Georg Brandlba83f822010-03-14 09:50:54 +00002881- Issue #7117: On almost all platforms: float-to-string and string-to-float
2882 conversions within Python are now correctly rounded. Places these conversions
2883 occur include: str for floats and complex numbers; the float and complex
2884 constructors; old-style and new-style numeric formatting; serialization and
2885 deserialization of floats and complex numbers using marshal, pickle and json;
2886 parsing of float and imaginary literals in Python code; Decimal-to-float
2887 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002888
Georg Brandlba83f822010-03-14 09:50:54 +00002889 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2890 providing correctly-rounded strtod and dtoa C functions. This code is
2891 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2892 the C compiler. There may be a small number of platforms on which correct
2893 operation of this code cannot be guaranteed, so the code is not used: notably,
2894 this applies to platforms where the C double format is not IEEE 754 binary64,
2895 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2896 and Python's configure script is unable to determine how to change the FPU
2897 precision. On these platforms conversions use the platform strtod and dtoa,
2898 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002899
Georg Brandlba83f822010-03-14 09:50:54 +00002900- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2901 uses the correctly-rounded string <-> float conversions described above (when
2902 available), and so produces correctly rounded results that will display nicely
2903 under the float repr. There are two related small changes: (1) round now
2904 accepts any class with an ``__index__()`` method for its second argument (but
2905 no longer accepts floats for the second argument), and (2) an excessively
2906 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2907 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003054- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3055 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3056 but with at least one decimal point and with a default precision
3057 of 12. Previously, the behavior the same but with a default precision of 6.
3058 This more closely matches ``str()``, and reduces surprises when adding
3059 alignment flags to the empty presentation type. This also affects the new
3060 complex.__format__ in the same way.
3061
3062- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

3180
Georg Brandlba83f822010-03-14 09:50:54 +00003181- Issue #4935: The overflow checking code in the expandtabs() method common to
3182 str, bytes and bytearray could be optimized away by the compiler, letting the
3183 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00003184
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00003185- Issue #3720: Fix a crash when an iterator modifies its class and removes its

3193 collecting the oldest generation) so that allocating lots of objects without
3194 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00003195 Martin von Löwis at

3199
Georg Brandlba83f822010-03-14 09:50:54 +00003200- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3201 existing .py counterpart, override the co_filename attributes of all code
3202 objects if the original filename is obsolete (which can happen if the file has
3203 been renamed, moved, or if it is accessed through different paths). Patch by
3204 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00003205

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00003208- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
3209 file with `str' filename on Windows.
3210
Antoine Pitrouaa687902009-01-01 14:11:22 +00003211- Issue #3680: Reference cycles created through a dict, set or deque iterator
3212 did not get collected.
3213
Georg Brandlba83f822010-03-14 09:50:54 +00003214- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
3215 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00003216
Benjamin Peterson7af65562008-12-29 17:56:58 +00003217- Issue #4764: With io.open, IOError.filename is set when trying to open a
3218 directory on POSIX systems.
3219
Benjamin Petersonfe231b02008-12-29 17:47:42 +00003220- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
3221 systems.
3222
Georg Brandl6425a2f2008-12-28 11:54:53 +00003223- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003224 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003225
Skip Montanarof205c132008-12-23 03:30:15 +00003226- Added test case to ensure attempts to read from a file opened for writing
3227 fail.
3228
Georg Brandlba83f822010-03-14 09:50:54 +00003229- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3230 elapsed times, not only when some objects are uncollectable/unreachable.
3231 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003232

3239 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003240

Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003242
Georg Brandlba83f822010-03-14 09:50:54 +00003243- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3244 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3245 instances. On a typical machine this saves 3 bytes of memory (on average) per
3246 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003247
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003248- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3249 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3250 instead of throwing a MemoryError.
3251
Georg Brandlba83f822010-03-14 09:50:54 +00003252- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3253 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003254
Benjamin Petersonc078f922008-11-21 22:27:24 +00003255- Issue #4367: Python would segfault during compiling when the unicodedata
3256 module couldn't be imported and \N escapes were present.
3257
Georg Brandlba83f822010-03-14 09:50:54 +00003258- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3259 file objects with closefd=False. The file descriptor is still kept open but
3260 the file object behaves like a closed file. The ``FileIO`` object also got a
3261 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003262
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003263- Issue #4348: Some bytearray methods returned that didn't cause any change to
3264 the bytearray, returned the same bytearray instead of a copy.
3265
Georg Brandlba83f822010-03-14 09:50:54 +00003266- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

3269
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003270- Issue #4048: The parser module now correctly validates relative imports.
3271
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003272- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3273 exec statement.
3274
Georg Brandlba83f822010-03-14 09:50:54 +00003275- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3276 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003277
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003278- Issue #4209: Enabling unicode_literals and the print_function in the same
3279 __future__ import didn't work.
3280
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003281- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003282 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003283
Georg Brandlba83f822010-03-14 09:50:54 +00003284- On windows, ``os.chdir()`` given unicode was not working if
3285 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3286 this code path is really executed because I cannot move to such directory on
3287 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003288
Georg Brandlba83f822010-03-14 09:50:54 +00003289- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3290 element is temporarily replaced with an equivalent frozenset. But the
3291 eventual KeyError would always report the empty ``frozenset()`` as the missing
3292 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003293
Georg Brandlba83f822010-03-14 09:50:54 +00003294- Issue #4509: Various issues surrounding resize of bytearray objects to which
3295 there are buffer exports.

3302
Georg Brandlba83f822010-03-14 09:50:54 +00003303- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003309- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3310 returned them on 64bit platforms.
3311
Walter Dörwalded960ac2009-05-03 22:36:33 +00003312- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3313 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3314 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3315 of using the replace error handler in PyUnicode_DecodeUTF8().
3316
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003317- Issue #3739: The unicode-internal encoder now reports the number of characters
3318 consumed like any other encoder (instead of the number of bytes).
3319
Georg Brandlba83f822010-03-14 09:50:54 +00003320- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3321 allocator will be automatically disabled when running under Valgrind. This
3322 gives improved memory leak detection when running under Valgrind, while taking
3323 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004546 leak-chasing test runs give sensible results. The previous method of reaping
4547 threads could return successfully while some Thread objects were still
4548 referenced. This also introduces a new private function: ``thread._count()``.

4555
R. David Murray14dcd432009-10-14 13:58:07 +00004556- Issue #7058: Added save/restore for things like sys.argv and cwd to
4557 runtest_inner in regrtest, with warnings if the called test modifies them,
4558 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004565- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4566 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004567 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4568 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00004573- Issue #5354: New test support function import_fresh_module() makes it easy to
4574 import both normal and optimised versions of modules. test_heapq and
4575 test_warnings have been adjusted to use it, tests for other modules with both
4576 C and Python implementations in the stdlib can be adjusted to use it over
4577 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004585- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4586 should cause a test to be skipped are now done using import_module from test
4587 support, which does the conversion.

4689
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004690- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4691 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4692 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4693 ``printf`` function, whereas PyString_FromFormat has an independent
4694 implementation and uses "%zd" on all platforms for size_t values.
4695 This makes a difference on win64, where ``printf`` needs "%Id" to display
4696 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004698- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4702 object; previously an int would be returned for small values. the __long__
4703 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004713 was correctly parsed but parsing of subsequent arguments failed.
4714
Vinay Sajip35e3b032008-09-01 14:33:59 +00004715- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004716 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4717 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4718 when given a tuple of classes as second argument, were looking up
4719 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4720 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004859What's New in Python 2.6 beta 3?
4860================================
4861
Barry Warsaw07a4a382008-08-21 01:15:08 +00004862*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004863
4864Core and Builtins
4865-----------------
4866
Guido van Rossumf8402962008-08-20 15:01:50 +00004867- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4868 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4869 extensions do not automatically benefit from the class attribute
4870 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4871 to their tp_flags field if they care. This is a backwards
4872 compatibility feature; in 3.0, all types will use the cache by
4873 default.
4874
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004875- Keyword arguments can now follow starred arguments. (``f(a, *args,
4876 keyword=23)`` is now valid syntax.)
4877
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004878- ctypes function pointers that are COM methods have a boolean True
4879 value again.
4880
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004881- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4882 by denying s# to parse objects that have a releasebuffer procedure,
4883 and introducing s*.
4884
Georg Brandl1e13ea92008-08-11 09:07:59 +00004885- Issue #3537: Fix an assertion failure when an empty but presized dict
4886 object was stored in the freelist.
4887
Mark Dickinsonb6467572008-08-04 21:30:09 +00004888- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4889 ValueError consistently across platforms.
4890
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004891- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4892 (64bit Unix, for example), unichr() would truncate its argument and return
4893 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4894
Neal Norwitze7d8be82008-07-31 17:17:14 +00004895- Apply security patches from Apple.
4896
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004897- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4898 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4899
Antoine Pitrou92f82162008-07-25 22:22:08 +00004900- Issue #1819: function calls with several named parameters are now on
4901 average 35% faster (as measured by pybench).
4902
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004903- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4904 the python debugger steps into a class statement: the free variables (local
4905 variables defined in an outer scope) would be deleted from the outer scope.
4906
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004907- Issue #2620: Overflow checking when allocating or reallocating memory
4908 was not always being done properly in some python types and extension
4909 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4910 all been updated to perform better checks and places in the code that
4911 would previously leak memory on the error path when such an allocation
4912 failed have been fixed.

4915-------
4916
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004917- Issue #3612: Added some missing basic types in ctypes.wintypes.
4918
Benjamin Petersone977ad42008-08-20 01:42:01 +00004919- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4920 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4921
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004922- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4923 version reported by these tools does not necessarily follow the python
4924 version numbering scheme, so the module is less strict when parsing it.
4925
Nick Coghlanf70385a2008-08-18 12:42:46 +00004926- Issue #2235: Added Py3k warnings for types which will become unhashable
4927 under the stricter __hash__ inheritance rules in 3.0. Several types
4928 which did not meet the rules for hash invariants and were already
4929 unhashable in 3.0 have now been explicitly flagged as unhashable in
4930 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4931 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4932
Brett Cannon88f801d2008-08-18 00:46:22 +00004933- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4934 imported into the module but exposed as part of the module's API.
4935
Brett Cannon7b96f072008-08-18 00:41:11 +00004936- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4937
Brett Cannon46225e72008-08-18 00:36:52 +00004938- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4939
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004940- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4941
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004942- Issue #3575: Incremental decoder's decode function now takes bytearray
4943 by using 's*' instead of 't#'.
4944
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004945- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004946 fails unicode conversion on 2nd parameter. (windows only)
4947
Georg Brandl222e2082010-08-01 22:27:39 +00004948- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004949 in a redirect.
4950
Brett Cannonabe423e2008-08-16 21:47:07 +00004951- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004952 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004953
Facundo Batistaeb90b782008-08-16 14:44:07 +00004954- Issue #2776: fixed small issue when handling an URL with double slash
4955 after a 302 response in the case of not going through a proxy.
4956
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004957- Issue #2676: in the email package, content-type parsing was hanging on
4958 pathological input because of quadratic or exponential behaviour of a
4959 regular expression.
4960
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004961- Issue #3476: binary buffered reading through the new "io" library is now
4962 thread-safe.
4963
Brett Cannonbf3157b2008-08-14 05:00:03 +00004964- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4965 since mimetools itself is deprecated. Because modules are cached, all
4966 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4967
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004968- Issue #3134: shutil referenced undefined WindowsError symbol.
4969
Robert Schuppenies14646332008-08-10 11:01:53 +00004970- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4971 menu entries were not deleted.
4972
Brett Cannon83e81842008-08-09 23:30:55 +00004973- Copied the implementation of reduce() to _functools.reduce() to have a
4974 version that did not raise a DeprecationWarning under -3.
4975
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004976- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4977 a MemoryError rather than silently stop the iteration.
4978
Guido van Rossum59ce9012008-08-09 14:55:34 +00004979- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4980 to _sre.compile() will now be rejected. This should not affect anybody
4981 since the re.compile() function never generates invalid re-bytecode.
4982
Skip Montanaroa032bf42008-08-08 22:52:51 +00004983- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4984 upon first access it can be automatically initialized from the csv file if
4985 it wasn't initialized during instantiation.
4986
Brett Cannon3aa2a492008-08-06 22:28:09 +00004987- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4988 the reload() built-in has been removed.
4989
Brett Cannon7e30b672008-08-04 21:52:25 +00004990- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004991 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4999 raised an AttributeError.
5000
Benjamin Peterson01a24322008-07-28 23:35:27 +00005001- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005002 asking for a specific length. This problem only affected files opened
5003 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005004
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005005- Issue #3449: Update decimal module to use most recent specification
5006 (v. 1.68) and tests (v. 2.58) from IBM.
5007
Georg Brandl222e2082010-08-01 22:27:39 +00005008- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005009

5012
Georg Brandlf9efabb2008-07-23 15:16:45 +00005013- Deprecate the "ast" parser function aliases.
5014
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005015- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5016
5017- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5018 invalid arguments.
5019
5020- Issue #3302: Fix several crashes when calling locale's gettext functions
5021 with None arguments.
5022
5023- Issue #3389: Allow resolving dotted names for handlers in logging
5024 configuration files.
5025
5026- Deprecate the sunaudio module for removal in Python 3.0.
5027
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005028- Issue #3394: zipfile.writestr sets external attributes when passed a
5029 file name rather than a ZipInfo instance, so files are extracted with
5030 mode 0600 rather than 000 under Unix.
5031
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005032- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5033 argument in python 2.5, this broke code that subclassed Popen to include its
5034 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5045 interaction with the tp_hash slot (added in 2.6b2) are now documented
5046
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005047- Issue #643841: The language reference now provides more detailed
5048 coverage of the lookup process for special methods. The disclaimers
5049 regarding lack of coverage of new-style classes have also been
5050 removed, since the coverage is now fairly reasonable.

5055
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005056*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005058Core and Builtins
5059-----------------
5060
Georg Brandl3e483f62008-07-16 22:57:41 +00005061- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5062 its methods now allow for items objects that can be converted to
5063 an integer using operator.index().
5064
Mark Dickinson64b7e502008-07-16 09:40:03 +00005065- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5066 produced a ValueError instead of giving the correct float.
5067
Eric Smitha5fa5a22008-07-16 00:11:49 +00005068- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5069 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5070
Mark Dickinson7103aa42008-07-15 19:08:33 +00005071- Issue #3008: the float type has a new instance method 'float.hex'
5072 and a new class method 'float.fromhex' to convert floating-point
5073 numbers to and from hexadecimal strings, respectively.
5074
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005075- Issue #2235: __hash__ is once again inherited by default. To allow
5076 collections.Hashable to remain meaningful in the presence of the
5077 default hash implementation (object.__hash__), it is now possible
5078 to explicit block inheritance of hash by setting __hash__=None at
5079 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5080 level.
5081
Nick Coghlanb028f502008-07-13 14:52:36 +00005082- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5083 the parent module cannot be found while performing an absolute import.
5084 This means that an incorrectly defined __package__ attribute will
5085 now only prevent relative imports in that module rather than causing
5086 all imports from that module to fail.
5087
Nick Coghlan14ff9942008-07-08 14:21:42 +00005088- Issue #2517: Allow unicode messages in Exceptions again by correctly
5089 bypassing the instance dictionary when looking up __unicode__ on
5090 new-style classes.
5091
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005092- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5093 set to a custom object whose write() method happens to install
5094 another file in sys.stdout.
5095
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005096- Issue #3088: Corrected a race condition in classes derived from
5097 threading.local: the first member set by a thread could be saved in
5098 another thread's dictionary.
5099
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005100- Issue #3004: Minor change to slice.indices(): the start and stop
5101 arguments are now treated identically, making the behaviour easier
5102 to describe and understand. For example, slice(None, -10,
5103 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5104 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5105 10, -1).
5106
Georg Brandl278fc502008-07-19 12:46:12 +00005107- Issue #3219: Calling a function with repeated keyword arguments,
5108 f(a=2, a=23), would not cause a syntax error. This was a regression
5109 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00005559 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005560
5561 This is controlled by the configure argument ``--with-universal-archs``:
5562

5564
5565 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5566
5567 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5568

Georg Brandl3ee81df2008-05-17 18:14:43 +00005621- Issue #1631171: Re-implement the 'warnings' module in C (the
5622 original Python code has been kept as backup). This will allow for
5623 using the 'warning's machinery in such places as the parser where
5624 use of pure Python code is not possible. Both the ``showarning()``
5625 and ``formatwarning()`` gain an optional 'line' argument which is
5626 not called by default for backwards-compatibility reasons. Setting
5627 ``warnings.showwarning()`` to an implementation that lacks support
5628 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005691- Issue #2550: The approach used by client/server code for obtaining
5692 ports to listen on in network-oriented tests has been refined in an
5693 effort to facilitate running multiple instances of the entire
5694 regression test suite in parallel without issue.
5695 test_support.bind_port() has been fixed such that it will always
5696 return a unique port -- which wasn't always the case with the
5697 previous implementation, especially if socket options had been set
5698 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5699 new implementation of bind_port() will actually raise an exception
5700 if it is passed an AF_INET/SOCK_STREAM socket with either the
5701 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5702 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5703 the socket it's been passed. This currently only applies to
5704 Windows. This option prevents any other sockets from binding to the
5705 host/port we've bound to, thus removing the possibility of the
5706 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5707 when a second SOCK_STREAM socket binds and accepts to a host/port
5708 that's already been bound by another socket. The optional preferred
5709 port parameter to bind_port() has been removed. Under no
5710 circumstances should tests be hard coding ports!
5711
5712 test_support.find_unused_port() has also been introduced, which will
5713 pass a temporary socket object to bind_port() in order to obtain an
5714 unused port. The temporary socket object is then closed and
5715 deleted, and the port is returned. This method should only be used
5716 for obtaining an unused port in order to pass to an external program
5717 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5718 a parameter to a server-oriented class that doesn't give you direct
5719 access to the underlying socket used.
5720
5721 Finally, test_support.HOST has been introduced, which should be used
5722 for the host argument of any relevant socket calls (i.e. bind and
5723 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005724
5725 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005726 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005727 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5728 test_asynchat and test_socket_ssl.
5729
Georg Brandl3ee81df2008-05-17 18:14:43 +00005730 It is now possible for multiple instances of the regression test
5731 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00005935- The bundled libffi copy is now in sync with the recently released
5936 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005937 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
5938 files are used. On all linux systems the --with-system-ffi
5939 configure option defaults to "yes".

Eric Smitha73fbe72008-02-23 03:09:44 +00006010- Added the future_builtins module, which contains hex() and oct().
6011 These are the PEP 3127 version of these functions, designed to be
6012 compatible with the hex() and oct() builtins from Python 3.0. They
6013 differ slightly in their output formats from the existing, unchanged
6014 Python 2.6 builtins. The expected usage of the future_builtins
6015 module is:
6016 from future_builtins import hex, oct
6017
Eric Smith7ef40bf2008-02-20 23:34:22 +00006018- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6019 exponents for exponents with absolute value < 100. Follows C99
6020 standard. This is a change on Windows, which would use 3 digits.
6021 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6022 so that any alterations it does to the resulting string will be
6023 available in stringlib/formatter.h (for float.__format__).
6024
Eric Smith5a3c1352008-02-19 13:21:56 +00006025- Implemented PEP 3101, Advanced String Formatting. This adds a new
6026 builtin format(); a format() method for str and unicode; a
6027 __format__() method to object, str, unicode, int, long, float, and
6028 datetime; the class string.Formatter; and the C API
6029 PyObject_Format().
6030
Georg Brandl3ee81df2008-05-17 18:14:43 +00006031- Fixed several potential crashes, all caused by specially crafted
6032 __del__ methods exploiting objects in temporarily inconsistent
6033 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006034
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006035- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006036 prevent a possible crash: an Abstract Base Class would try to access
6037 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006038

Georg Brandl3ee81df2008-05-17 18:14:43 +00006042- Clear all free lists during a gc.collect() of the highest generation
6043 in order to allow pymalloc to free more arenas. Python may give back
6044 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006045
Georg Brandl3ee81df2008-05-17 18:14:43 +00006046- Issue #2045: Fix an infinite recursion triggered when printing a
6047 subclass of collections.defaultdict, if its default_factory is set
6048 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006049
Christian Heimesf75dbef2008-02-08 00:11:31 +00006050- Fixed a minor memory leak in dictobject.c. The content of the free
6051 list was not freed on interpreter shutdown.
6052
Georg Brandl21e99f42010-03-07 15:23:59 +00006053- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006054 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006055
Georg Brandl3ee81df2008-05-17 18:14:43 +00006056- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6057 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006058 to compact the internal free lists of pre-allocted ints and floats.
6059
Georg Brandl3ee81df2008-05-17 18:14:43 +00006060- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6061 calls. Python expected the return type int but the fork familie
6062 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006063
Georg Brandl3ee81df2008-05-17 18:14:43 +00006064- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6065 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006076- Patch #1473257: generator objects gain a gi_code attribute. This is
6077 the same object as the func_code attribute of the function that
6078 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006079
Georg Brandl3ee81df2008-05-17 18:14:43 +00006080- Issue #1920: "while 0" statements were completely removed by the
6081 compiler, even in the presence of an "else" clause, which is
6082 supposed to be run when the condition is false. Now the compiler
6083 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006084
Guido van Rossumeead05f2008-01-24 18:21:02 +00006085- A few crashers fixed: weakref_in_del.py (issue #1377858);
6086 loosing_dict_ref.py (issue #1303614, test67.py);
6087 borrowed_ref_[34].py (not in tracker).
6088

6092
Georg Brandl3ee81df2008-05-17 18:14:43 +00006093- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006094 several extension methods and modules do not work without unicode
6095 support.
6096
Georg Brandl26543b12008-01-21 18:36:51 +00006097- Issue #1882: when compiling code from a string, encoding cookies in the
6098 second line of code were not always recognized correctly.
6099
Georg Brandl14404b62008-01-19 19:27:05 +00006100- Issue #1679: "0x" was taken as a valid integer literal.
6101
Georg Brandl6caad7d2008-01-26 14:19:22 +00006102- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006103 added.
6104
Christian Heimesc94e2b52008-01-14 04:13:37 +00006105- sys.float_info / PyFloat_GetInfo: The floating point information
6106 object was converted from a dict to a specialized structseq object.
6107
Georg Brandl3ee81df2008-05-17 18:14:43 +00006108- Patch #1816: Added sys.flags structseq. It exposes the status of
6109 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006110
Georg Brandl3ee81df2008-05-17 18:14:43 +00006111- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006137 and INF. float("nan"), float("inf") and float("-inf") now work on
6138 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006139
Georg Brandl3ee81df2008-05-17 18:14:43 +00006140- Compiler now generates simpler and faster code for dictionary
6141 literals. The oparg for BUILD_MAP now indicates an estimated
6142 dictionary size. There is a new opcode, STORE_MAP, for adding
6143 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006172- Patch #1739468: Directories and zipfiles containing a __main__.py
6173 file can now be directly executed by passing their name to the
6174 interpreter. The directory/zipfile is automatically inserted as the
6175 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006177- Issue #1265: Fix a problem with sys.settrace, if the tracing
6178 function uses a generator expression when at the same time the
6179 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006180
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006181- sets and frozensets now have an isdisjoint() method.
6182

6184
Neal Norwitz44f326e2007-10-05 05:29:17 +00006185- Fix warnings found by the new version of the Coverity checker.
6186
Georg Brandl21e99f42010-03-07 15:23:59 +00006187- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006188 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6189 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006190
Georg Brandl3ee81df2008-05-17 18:14:43 +00006191- Issue #1686386: Tuple's tp_repr did not take into account the
6192 possibility of having a self-referential tuple, which is possible
6193 from C code. Nor did object's tp_str consider that a type's tp_str
6194 could do something that could lead to an inifinite recursion.
6195 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6196 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006197
Georg Brandl3ee81df2008-05-17 18:14:43 +00006198- Issue #1164: It was possible to trigger deadlock when using the
6199 'print' statement to write to a file since the GIL was not released
6200 as needed. Now PyObject_Print() does the right thing along with
6201 various tp_print implementations of the built-in types and those in
6202 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006203
Georg Brandl3ee81df2008-05-17 18:14:43 +00006204- Issue #1147: Exceptions were directly allowing string exceptions in
6205 their throw() method even though string exceptions no longer
6206 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006207
Georg Brandl3ee81df2008-05-17 18:14:43 +00006208- Issue #1096: Prevent a segfault from getting the repr of a very
6209 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006210
Brett Cannon1e534b52007-09-07 04:18:30 +00006211- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006212 PyObject_Call() never calling back out to Python code to trigger
6213 recursion depth updates/checks. Required the creation of a static
6214 RuntimeError instance in case normalizing an exception put the
6215 recursion check value past its limit. Fixes crashers
6216 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006217
Georg Brandl3ee81df2008-05-17 18:14:43 +00006218- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006231- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006232 __*__ attributes. (Some already existed, e.g., __doc__ and
6233 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006234
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006235- Add -3 option to the interpreter to warn about features that are
6236 deprecated and will be changed/removed in Python 3.0.
6237
Georg Brandl2134e752007-05-21 20:34:16 +00006238- Patch #1686487: you can now pass any mapping after '**' in function
6239 calls.
6240
Collin Winter62903052007-05-18 23:11:24 +00006241- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006242 "except E as target:". This is to provide forwards compatibility
6243 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006244
Brett Cannon229cee22007-05-05 01:34:02 +00006245- Deprecate BaseException.message as per PEP 352.
6246
Georg Brandl3ee81df2008-05-17 18:14:43 +00006247- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006248 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006249
Vinay Sajip8549ce32007-05-06 17:53:37 +00006250- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006251 setting a plain string, ie don't expand to single letter identifiers.
6252
Raymond Hettinger13936692007-04-11 18:40:58 +00006253- Request #1191699: Slices can now be pickled.
6254
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006255- Request #1193128: str.translate() now allows a None argument for
6256 translations that only remove characters without re-mapping the
6257 remaining characters.
6258
Georg Brandl5cb76c12007-03-21 09:00:39 +00006259- Patch #1682205: a TypeError while unpacking an iterable is no longer
6260 masked by a generic one with the message "unpack non-sequence".
6261
Neal Norwitzaa754b72007-03-21 06:39:48 +00006262- Remove unused file Python/fmod.c.
6263
Guido van Rossum143b5642007-03-23 04:58:42 +00006264- Bug #1683368: The object.__init__() and object.__new__() methods are
6265 now stricter in rejecting excess arguments. The only time when
6266 either allows excess arguments is when it is not overridden and the
6267 other one is. For backwards compatibility, when both are
6268 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006269 warning later). Also, type.__init__() insists on the same signature
6270 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006271
Georg Brandl3ee81df2008-05-17 18:14:43 +00006272- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6273 object to complex using its __complex__() method before falling back
6274 to the __float__() method. Therefore, the functions in the cmath
6275 module now can operate on objects that define a __complex__()
6276 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006277
Georg Brandl3ee81df2008-05-17 18:14:43 +00006278- Patch #1623563: allow __class__ assignment for classes with
6279 __slots__. The old and the new class are still required to have the
6280 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006281

6286 ``object.__reduce_ex__()`` is called with an object that is faking
6287 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006288
Georg Brandl3ee81df2008-05-17 18:14:43 +00006289- Patch #1680015: Don't modify __slots__ tuple if it contains an

6293
Georg Brandl7b9c5552007-03-12 14:30:05 +00006294- Bug #1678647: write a newline after printing an exception in any
6295 case, even when converting the value to a string failed.
6296
Georg Brandl871f1bc2007-03-12 13:17:36 +00006297- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006298 its argument, if it exists. If not, it will work like before. This
6299 allows customizing the output of dir() in the presence of a
6300 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00006302- Patch #922167: Python no longer segfaults when faced with infinitely
6303 self-recursive reload() calls (as reported by bug #742342).
6304

Georg Brandl3ee81df2008-05-17 18:14:43 +00006308- Patch #1491866: change the complex() constructor to allow
6309 parthensized forms. This means complex(repr(x)) now works instead of
6310 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006311
Georg Brandlaa2321b2007-03-07 00:40:28 +00006312- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006313 makes the filenames the warning module prints much more sensible
6314 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006315
Georg Brandl49aafc92007-03-07 00:34:46 +00006316- Variant of patch #697613: don't exit the interpreter on a SystemExit
6317 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006318 variable is given, but break into the interactive interpreter just
6319 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00006326
Georg Brandl0fca97a2007-03-05 22:28:08 +00006327- Patch #1674228: when assigning a slice (old-style), check for the
6328 sq_ass_slice instead of the sq_slice slot.
6329
Georg Brandl3ee81df2008-05-17 18:14:43 +00006330- When printing an unraisable error, don't print exceptions. before
6331 the name. This duplicates the behavior whening normally printing
6332 exceptions.

6960 -- the failure just occurred later, with a more cumbersome
6961 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007242- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7243 with RFC 3207 and forgets any knowledge obtained from the server not
7244 obtained from the TLS negotiation itself. Patch contributed by Bill
7245 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007246
Georg Brandl3ee81df2008-05-17 18:14:43 +00007247- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007248 that the SMTP.starttls() caller no longer needs to call ehlo()
7249 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007250 does not claim to support starttls. Adds the
7251 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7332 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7333 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00007335

Georg Brandl3ee81df2008-05-17 18:14:43 +00007350 time so that opening a database previously created with the DB_DUP
7351 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7352 opens. Specifically: dictionary assignment to a DB object will
7353 replace all values for a given key when the database allows
7354 duplicate values. DB users should use DB.put(k, v) when they want
7355 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007356

7362 characters with ASCII value less than 32. Also, it correctly quotes
7363 dots only if they occur on a single line, as opposed to the previous
7364 behavior of quoting dots if they are the second character of any
7365 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007366

7688-----
7689
Georg Brandl3ee81df2008-05-17 18:14:43 +00007690- Unified naming convention for free lists and their limits. All free
7691 lists in Object/ are named ``free_list``, the counter ``numfree``

7693 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007694
Georg Brandl3ee81df2008-05-17 18:14:43 +00007695- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7696 to ``PyTuple_SetItem``, it can be used to populate a brand new

7709
Georg Brandl3ee81df2008-05-17 18:14:43 +00007710- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7711 of w# format code incorrectly truncated the length to an int, even
7712 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7713 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007714
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7733- Fix some leftovers from the conversion from int to Py_ssize_t
7734 (relevant to strings and sequences of more than 2**31 items).
7735
7736- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7737 outside of pystate.c and should not be necessary.
7738
Georg Brandl3ee81df2008-05-17 18:14:43 +00007739- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7740 absolute imports. In earlier versions they might have used relative
7741 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007742
Georg Brandl3ee81df2008-05-17 18:14:43 +00007743- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7744 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007745
Georg Brandl3ee81df2008-05-17 18:14:43 +00007746- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00007753- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7754 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7755 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7756 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007757

7770
Georg Brandl3ee81df2008-05-17 18:14:43 +00007771- Removed the macfs module. It had been deprecated since Python 2.5.
7772 This lead to the deprecation of macostools.touched() as it relied
7773 solely on macfs and was a no-op under OS X.
