19 effect of appearing to resolve the issue. Thanks to Mark Shannon for
20 noticing.

37 warnings. Patch by Josh Triplett and Petri Lehtinen.
38
Mark Hammond323b5da2011-10-17 11:05:36 +110039- Issue #7833: Extension modules built using distutils on Windows will no
40 longer include a "manifest" to prevent them failing at import time in some
41 embedded situations.
42
Benjamin Petersona7b09762011-10-15 13:43:21 -040043- Issue #13186: Fix __delitem__ on old-style instances when invoked through
44 PySequence_DelItem.

Mark Dickinsondbbed042011-09-19 16:38:08 +010052- Issue #12973: Fix overflow checks that invoked undefined behaviour in
53 int.__pow__. These overflow checks were causing int.__pow__ to produce
54 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010055 compiler optimizing the check away. Also fix similar overflow checks
56 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
57 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010058

66 non-exception class.

Antoine Pitrou16166452011-07-12 22:04:20 +020068- Issue #12149: Update the method cache after a type's dictionnary gets
69 cleared by the garbage collector. This fixes a segfault when an instance
70 and its type get caught in a reference cycle, and the instance's
71 deallocator calls one of the methods on the type (e.g. when subclassing
72 IOBase). Diagnosis and patch by Davide Rizzo.
73
Florent Xiclunaa1f948b2012-01-24 21:05:10 +010074- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +020081 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
82 raw_input() interrupted by CTRL+c.
83
Łukasz Langa7a153902011-10-18 17:16:00 +020084- Issue #10860: httplib now correctly handles an empty port after port
85 delimiter in URLs.
86
Barry Warsawc5643282011-07-19 17:06:30 -040087- dict_proxy objects now display their contents rather than just the class
88 name.

Florent Xiclunac2279652012-02-12 14:49:03 +0100101- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100102 has left two versions of customize_compiler, the original in
103 distutils.sysconfig and another copy in distutils.ccompiler, with some
104 parts of distutils calling one and others using the other.
105 Complete the revert back to only having one in distutils.sysconfig as
106 is the case in 3.x.
107
Ned Deily0d0ea482012-02-10 12:59:06 +0100108- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
109 Distutils-based packages with C extension modules may fail because
110 Apple has removed gcc-4.2, the version used to build python.org
111 64-bit/32-bit Pythons. If the user does not explicitly override
112 the default C compiler by setting the CC environment variable,
113 Distutils will now attempt to compile extension modules with clang
114 if gcc-4.2 is required but not found. Also as a convenience, if
115 the user does explicitly set CC, substitute its value as the default
116 compiler in the Distutils LDSHARED configuration variable for OS X.
117 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
118 SDK, neither of which are available in Xcode 4. This change does not
119 attempt to override settings to support their use with Xcode 4.)
120
Senthil Kumaran59e7c8f2012-02-09 18:22:01 +0800121- Issue #9021: Add an introduction to the copy module documentation.
122
Senthil Kumaran607e31e2012-02-09 17:43:31 +0800123- Issue #6005: Examples in the socket library documentation use sendall, where
124 relevant, instead send method.
125
Petri Lehtinenc7fd5232011-05-09 12:24:09 +0200126- Issue #10811: Fix recursive usage of cursors. Instead of crashing,
127 raise a ProgrammingError now.
128
Ned Deily2c8bf042012-02-06 00:55:50 +0100129- Issue #10881: Fix test_site failures with OS X framework builds.

207 Patch by sbt.
208

Ned Deily87e82bb2011-06-28 19:52:59 -0700394- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
395 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
396 interpreter process. This could cause failures in non-Distutils subprocesses
397 and was unreliable since tests or user programs could modify the interpreter
398 environment after Distutils set it. Instead, have Distutils set the the
399 deployment target only in the environment of each build subprocess. It is
400 still possible to globally override the default by setting
401 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
402 greater or equal to the default value, the value with which the interpreter
403 was built.

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

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00001210- Issue #9869: Make long() and PyNumber_Long return something of type
1211 long for a class whose __long__ method returns a plain int. This
1212 fixes an interpreter crash when initializing an instance of a long
1213 subclass from an object whose __long__ method returns a plain int.

1218 thread-local storage key.
1219
Victor Stinnercaafd772010-09-08 10:51:01 +00001220- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
1221 encoding and errors attributes instead of using utf-8 in strict mode, to get
1222 the same behaviour than the print statement.
1223
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00001224- Issue #9737: Fix a crash when trying to delete a slice or an item from

1237 output with no type specifier failed to match the str output:
1238
1239 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
1240 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
1241

1334

1336 received. Now sendall() properly calls signal handlers if necessary,
1337 and retries sending if these returned successfully, including on sockets

1349 handles non-blocking readinto() returning None correctly.
1350

1352 SSLSocket.sendto() to match the corresponding socket methods. Also,
1353 fix various SSLSocket methods to raise socket.error rather than an
1354 unhelpful TypeError when called on an unconnected socket. Original patch
1355 by Andrew Bennetts.
1356
Raymond Hettinger74f869e2010-09-13 22:14:36 +00001357- Issue #9826: OrderedDict.__repr__ can now handle self-referential
1358 values: d['x'] = d.
1359

1364
Raymond Hettinger20397532010-09-12 02:11:45 +00001365- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1366 This prevents user-created self-referencing ordered dictionaries from
1367 becoming permanently uncollectable GC garbage. The downside is that
1368 removing __del__ means that the internal doubly-linked list has to wait for
1369 GC collection rather than freeing memory immediately when the refcnt drops
1370 to zero.
1371
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001372- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00001373 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001374 value.
1375
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001376- Issue #9792: In case of connection failure, socket.create_connection()
1377 would swallow the exception and raise a new one, making it impossible
1378 to fetch the original errno, or to filter timeout errors. Now the
1379 original error is re-raised.
1380
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001381- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1382 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1383 be updated back after the system call. Original patch by Brian Brazil.
1384
Antoine Pitroudca9de92010-09-04 17:52:26 +00001385- Issue #1100562: Fix deep-copying of objects derived from the list and

1389 ConfigParser.write.
1390
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001391- Issue #808164: Fixed socket.close to avoid references to globals, to
1392 avoid issues when socket.close is called from a __del__ method.
1393
Terry Reedyd2d2ae92010-11-11 23:22:19 +00001394- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
1395 can be set to False to turn off the previously undocumented 'popularity'
1396 heuristic. Patch by Terry Reedy and Eli Bendersky
1397
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00001398- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
1399 falling into recursion.
1400
R. David Murray7c4bf552010-08-25 01:45:57 +00001401- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1402 character years even if the message contains RFC822 two character years.
1403
Daniel Stutzbach91287322010-08-24 21:09:30 +00001404- Issue #8750: Fixed MutableSet's methods to correctly handle

1414
Raymond Hettinger917bba12010-08-22 08:01:58 +00001415- Issue #9214: Set operations on KeysView or ItemsView in the collections
1416 module now correctly return a set. (Patch by Eli Bendersky.)
1417
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001418- Issue #9617: Signals received during a low-level write operation aren't
1419 ignored by the buffered IO layer anymore.
1420
Benjamin Peterson52c36052010-08-21 03:03:22 +00001421- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
1422 are not held onto after they are deleted elsewhere.
1423
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001424- Issue #9626: the view methods for collections.OrderedDict() were returning
1425 the unordered versions inherited from dict. Those methods are now
1426 overridden to provide ordered views.
1427
Éric Araujo0389ae62010-08-14 03:07:46 +00001428- Issue #8688: MANIFEST files created by distutils now include a magic

1430 without this marker will not be overwritten or removed.
1431
Antoine Pitroue1436d12010-08-12 15:25:51 +00001432- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1433 and a BadZipfile error is raised if it doesn't match (as used to be the
1434 case in Python 2.5 and earlier).
1435
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001436- Issue #9550: a BufferedReader could issue an additional read when the
1437 original read request had been satisfied, which could block indefinitely
1438 when the underlying raw IO channel was e.g. a socket. Report and original
1439 patch by Jason V. Miller.
1440
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001441- Issue #9551: Don't raise TypeError when setting the value to None for

1457 PROT_WRITE and PROT_EXEC.
1458
Senthil Kumarane677ecf2010-08-08 11:56:31 +00001459- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
1460 This is how it is supposed to work, wget and curl do the same. Previous
1461 behavior was wrong.
1462
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +00001463- Issue #2944: asyncore doesn't handle connection refused correctly.

1827-----------------
1828
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001829- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1830 start byte and the continuation byte(s) are now considered invalid, instead
1831 of the number of bytes specified by the start byte.
1832 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1833 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1834 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1835 Previous versions returned a single u'\ufffd'.
1836
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001837- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001838 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1839 arises from the "Overriding __eq__ blocks inheritance ..." warning
1840 when turned into an exception: in this case the exception simply
1841 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001842
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001843- Issue #8748: Fix two issues with comparisons between complex and integer
1844 objects. (1) The comparison could incorrectly return True in some cases
1845 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1846 (2) The comparison raised an OverflowError for large integers, leading
1847 to unpredictable exceptions when combining integers and complex objects
1848 in sets or dicts.
1849
Mark Dickinson81336372010-05-30 12:12:25 +00001850- Issue #5211: Implicit coercion for the complex type is now completely
1851 removed. (Coercion for arithmetic operations was already removed in 2.7
1852 alpha 4, but coercion for rich comparisons was accidentally left in.)
1853
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001854- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1855 and error handler, instead of writing to the C stderr file in utf-8
1856
Georg Brandlfee0f442010-05-22 21:26:21 +00001857- Issue #7902: When using explicit relative import syntax, don't try implicit
1858 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00001859

1861 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +00001862
Victor Stinnerb65bd2e2010-06-11 19:22:28 +00001863- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00001864 Window Server again in a framework build on MacOSX 10.5 or earlier.

2042 operation raises multiple signals and more than one of those signals is
2043 trapped, the specification determines the order in which the signals should be

2231 with a non-empty format string. This is an effort to future-proof user
2232 code. If a derived class does not currently implement __format__ but later
2233 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002234 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002235 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002268- Issue #8257: The Decimal construct now accepts a float instance directly,
2269 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002270
2271 >>> Decimal(1.1)
2272 Decimal('1.100000000000000088817841970012523233890533447265625')
2273

Georg Brandlfee0f442010-05-22 21:26:21 +00002285- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2286 InvalidOperation instead of returning False. (Comparisons involving a quiet
2287 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2288 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00002290- Issue #2531: Comparison operations between floats and Decimal instances now
2291 return a result based on the numeric values of the operands; previously they
2292 returned an arbitrary result based on the relative ordering of id(float) and
2293 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002295- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002296 argument `-` which tells it to read files to compile from stdin. Each line is
2297 read on demand and the named file is compiled immediately. (Original patch by
2298 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00002307- Comparisons using one of <, <=, >, >= between a complex instance and a
2308 Fractions instance now raise TypeError instead of returning True/False. This
2309 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2310 <=> complex, and complex <=> complex comparisons.

2410 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002414- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2415 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2416 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002417 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2418 inconsistent: __int__ was used for some integer codes but not for others, and
2419 the set of integer codes for which it was used differed between native packing
2420 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002728 file position when calling `truncate()`. It would previously change the file
2729 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002730 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00002732- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2733 class used to represent files stored inside an archive. The new
2734 implementation is significantly faster and can be wrapped in a
2735 ``io.BufferedReader`` object for more speedups. It also solves an issue
2736 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002747- Issue #7748: Since unicode values are supported for some metadata options in

2749 encoded string for them. This ensures that the upload and register commands
2750 send the correct values to PyPI without any error.

2826
Georg Brandlba83f822010-03-14 09:50:54 +00002827- The ``__complex__()`` method is now looked up on the class of instances to
2828 make it consistent with other special methods.

2832
Mark Dickinson1b34d252010-01-01 17:27:30 +00002833- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002834 DeprecationWarning when passed a float argument where an integer was expected.
2835 These functions and methods now raise TypeError instead. The majority of the
2836 effects of this change are in the extension modules, but some core functions
2837 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2838 and many unicode/str methods.

2852 of integers: the result of a/b is now correctly rounded for ints a and b (at
2853 least on IEEE 754 platforms), and in particular does not depend on the
2854 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003003- Issue #3382: 'F' formatting for float and complex now convert the result to
3004 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3005 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003006
Georg Brandlba83f822010-03-14 09:50:54 +00003007- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3008 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003009
Georg Brandlba83f822010-03-14 09:50:54 +00003010- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3011 1e-100 used to raise OverflowError, but now gives the requested 120
3012 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00003013
Georg Brandlba83f822010-03-14 09:50:54 +00003014- Add Py3k warnings for parameter names in parentheses.

3019 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003020
Georg Brandlba83f822010-03-14 09:50:54 +00003021- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3022 decimal string that's guaranteed to round back to x under correct rounding
3023 (with round-half-to-even rounding mode). Previously it gave a string based on
3024 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3025 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3026 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003027
Georg Brandlba83f822010-03-14 09:50:54 +00003028- Issue #7117: On almost all platforms: float-to-string and string-to-float
3029 conversions within Python are now correctly rounded. Places these conversions
3030 occur include: str for floats and complex numbers; the float and complex
3031 constructors; old-style and new-style numeric formatting; serialization and
3032 deserialization of floats and complex numbers using marshal, pickle and json;
3033 parsing of float and imaginary literals in Python code; Decimal-to-float
3034 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003035
Georg Brandlba83f822010-03-14 09:50:54 +00003036 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3037 providing correctly-rounded strtod and dtoa C functions. This code is
3038 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3039 the C compiler. There may be a small number of platforms on which correct
3040 operation of this code cannot be guaranteed, so the code is not used: notably,
3041 this applies to platforms where the C double format is not IEEE 754 binary64,
3042 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3043 and Python's configure script is unable to determine how to change the FPU
3044 precision. On these platforms conversions use the platform strtod and dtoa,
3045 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003046
Georg Brandlba83f822010-03-14 09:50:54 +00003047- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3048 uses the correctly-rounded string <-> float conversions described above (when
3049 available), and so produces correctly rounded results that will display nicely
3050 under the float repr. There are two related small changes: (1) round now
3051 accepts any class with an ``__index__()`` method for its second argument (but
3052 no longer accepts floats for the second argument), and (2) an excessively
3053 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3054 raises an exception.

3057
Georg Brandlba83f822010-03-14 09:50:54 +00003058- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00003201- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3202 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3203 but with at least one decimal point and with a default precision
3204 of 12. Previously, the behavior the same but with a default precision of 6.
3205 This more closely matches ``str()``, and reduces surprises when adding
3206 alignment flags to the empty presentation type. This also affects the new
3207 complex.__format__ in the same way.
3208
3209- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3210 classtype's, even if it was None. property now inserts the __doc__ into the
3211 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00003431- On windows, ``os.chdir()`` given unicode was not working if
3432 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3433 this code path is really executed because I cannot move to such directory on
3434 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003436- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3437 element is temporarily replaced with an equivalent frozenset. But the
3438 eventual KeyError would always report the empty ``frozenset()`` as the missing
3439 key. Now it correctly refers to the initial element.

3460 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00004693 leak-chasing test runs give sensible results. The previous method of reaping
4694 threads could return successfully while some Thread objects were still

4834
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004835- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4836
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004837- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4838 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4839 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4840 ``printf`` function, whereas PyString_FromFormat has an independent
4841 implementation and uses "%zd" on all platforms for size_t values.
4842 This makes a difference on win64, where ``printf`` needs "%Id" to display
4843 64bit values.
4844
Benjamin Peterson97179b02008-09-09 20:55:01 +00004845- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4846 error.
4847
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004848- Issue #3777: long() applied to a float object now always return a long
4849 object; previously an int would be returned for small values. the __long__
4850 method is allowed to return either an int or a long, but the behaviour of
4851 float objects should not change to respect backward compatibility.
4852
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004853- Issue #3751: str.rpartition would perform a left-partition when called with
4854 a unicode argument.
4855
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004856- Issue #3683: Fix compilation when --without-threads is given.
4857
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004858- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004859 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004860 was correctly parsed but parsing of subsequent arguments failed.
4861
Vinay Sajip35e3b032008-09-01 14:33:59 +00004862- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004863 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4864 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4865 when given a tuple of classes as second argument, were looking up
4866 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4867 type object.
4868
Neal Norwitz18aa3882008-08-24 05:04:52 +00004869- Fix crashes on memory allocation failure found with failmalloc.
4870
4871- Fix memory leaks found with valgrind and update suppressions file.
4872
4873- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4874
4875- Fix problem using wrong name in decimal module reported by pychecker.
4876
Christian Heimes7d4c3172008-08-22 19:47:25 +00004877- Silenced another compiler warning about a used but not defined
4878 function 'stringlib_contains_obj'.
4879
Benjamin Peterson712ee922008-08-24 18:10:20 +00004880- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4881 ``__delslice__``.
4882
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004883- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4884 library targets in the Makefile.
4885
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004886- Issue #1204: The configure script now tests for additional libraries
4887 that may be required when linking against readline. This fixes issues
4888 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00004912 return a list or None rather than a custom object.
4913
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004914- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004938 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4939 for catch_warnings() also led to an improvement in the raising of a
4940 DeprecationWarning related to warnings.warn_explicit().
4941
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004942- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005006What's New in Python 2.6 beta 3?
5007================================
5008
Barry Warsaw07a4a382008-08-21 01:15:08 +00005009*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005010
5011Core and Builtins
5012-----------------
5013
Guido van Rossumf8402962008-08-20 15:01:50 +00005014- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5015 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5016 extensions do not automatically benefit from the class attribute
5017 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5018 to their tp_flags field if they care. This is a backwards
5019 compatibility feature; in 3.0, all types will use the cache by
5020 default.
5021
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005022- Keyword arguments can now follow starred arguments. (``f(a, *args,
5023 keyword=23)`` is now valid syntax.)
5024
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005025- ctypes function pointers that are COM methods have a boolean True
5026 value again.
5027
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005028- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5029 by denying s# to parse objects that have a releasebuffer procedure,
5030 and introducing s*.
5031
Georg Brandl1e13ea92008-08-11 09:07:59 +00005032- Issue #3537: Fix an assertion failure when an empty but presized dict
5033 object was stored in the freelist.
5034
Mark Dickinsonb6467572008-08-04 21:30:09 +00005035- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5036 ValueError consistently across platforms.
5037
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005038- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5039 (64bit Unix, for example), unichr() would truncate its argument and return
5040 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5041
Neal Norwitze7d8be82008-07-31 17:17:14 +00005042- Apply security patches from Apple.
5043
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005044- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5045 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5046
Antoine Pitrou92f82162008-07-25 22:22:08 +00005047- Issue #1819: function calls with several named parameters are now on
5048 average 35% faster (as measured by pybench).
5049
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005050- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5051 the python debugger steps into a class statement: the free variables (local
5052 variables defined in an outer scope) would be deleted from the outer scope.
5053
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005054- Issue #2620: Overflow checking when allocating or reallocating memory
5055 was not always being done properly in some python types and extension
5056 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5057 all been updated to perform better checks and places in the code that
5058 would previously leak memory on the error path when such an allocation
5059 failed have been fixed.

5065
Benjamin Petersone977ad42008-08-20 01:42:01 +00005066- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5067 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5068
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005069- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5070 version reported by these tools does not necessarily follow the python
5071 version numbering scheme, so the module is less strict when parsing it.
5072
Nick Coghlanf70385a2008-08-18 12:42:46 +00005073- Issue #2235: Added Py3k warnings for types which will become unhashable
5074 under the stricter __hash__ inheritance rules in 3.0. Several types
5075 which did not meet the rules for hash invariants and were already
5076 unhashable in 3.0 have now been explicitly flagged as unhashable in
5077 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5078 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5079
Brett Cannon88f801d2008-08-18 00:46:22 +00005080- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5081 imported into the module but exposed as part of the module's API.
5082
Brett Cannon7b96f072008-08-18 00:41:11 +00005083- Remove an unneeded import of abc.ABCMeta from 'inspect'.

5088
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005089- Issue #3575: Incremental decoder's decode function now takes bytearray
5090 by using 's*' instead of 't#'.
5091
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005092- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005093 fails unicode conversion on 2nd parameter. (windows only)
5094
Georg Brandl222e2082010-08-01 22:27:39 +00005095- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005096 in a redirect.
5097

Antoine Pitroude781a42008-08-09 12:43:23 +00005149 asking for a specific length. This problem only affected files opened

5176 file name rather than a ZipInfo instance, so files are extracted with
5177 mode 0600 rather than 000 under Unix.
5178
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005179- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

5193
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005194- Issue #643841: The language reference now provides more detailed
5195 coverage of the lookup process for special methods. The disclaimers
5196 regarding lack of coverage of new-style classes have also been
5197 removed, since the coverage is now fairly reasonable.

5206-----------------
5207
Georg Brandl3e483f62008-07-16 22:57:41 +00005208- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5209 its methods now allow for items objects that can be converted to
5210 an integer using operator.index().
5211
Mark Dickinson64b7e502008-07-16 09:40:03 +00005212- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5213 produced a ValueError instead of giving the correct float.
5214
Eric Smitha5fa5a22008-07-16 00:11:49 +00005215- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5216 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5217
Mark Dickinson7103aa42008-07-15 19:08:33 +00005218- Issue #3008: the float type has a new instance method 'float.hex'
5219 and a new class method 'float.fromhex' to convert floating-point
5220 numbers to and from hexadecimal strings, respectively.
5221
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005222- Issue #2235: __hash__ is once again inherited by default. To allow
5223 collections.Hashable to remain meaningful in the presence of the
5224 default hash implementation (object.__hash__), it is now possible
5225 to explicit block inheritance of hash by setting __hash__=None at
5226 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5227 level.
5228
Nick Coghlanb028f502008-07-13 14:52:36 +00005229- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5230 the parent module cannot be found while performing an absolute import.
5231 This means that an incorrectly defined __package__ attribute will
5232 now only prevent relative imports in that module rather than causing
5233 all imports from that module to fail.
5234
Nick Coghlan14ff9942008-07-08 14:21:42 +00005235- Issue #2517: Allow unicode messages in Exceptions again by correctly
5236 bypassing the instance dictionary when looking up __unicode__ on
5237 new-style classes.

5240 set to a custom object whose write() method happens to install
5241 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005243- Issue #3088: Corrected a race condition in classes derived from
5244 threading.local: the first member set by a thread could be saved in
5245 another thread's dictionary.
5246
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005247- Issue #3004: Minor change to slice.indices(): the start and stop
5248 arguments are now treated identically, making the behaviour easier
5249 to describe and understand. For example, slice(None, -10,
5250 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5251 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5252 10, -1).
5253
Georg Brandl278fc502008-07-19 12:46:12 +00005254- Issue #3219: Calling a function with repeated keyword arguments,
5255 f(a=2, a=23), would not cause a syntax error. This was a regression
5256 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005257
Georg Brandl278fc502008-07-19 12:46:12 +00005258- Issue #2862: Make int and float freelist management consistent with
5259 other freelists. Changes their CompactFreeList apis into

5266 api functions without holding the GIL, which could lead to a fatal
5267 error when they failed.
5268
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005269- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005294- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5295 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005296 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005297 content-length. The problem had been corrected in the 2.4 branch, but never
5298 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005313- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5315
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005316- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5701
Brett Cannonb61d8012008-05-11 23:39:04 +00005702- ``Lib/lib-old`` is now added to sys.path.
5703
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005704- On MacOS X it is now possible to install the framework in 64-bit
5705 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005706 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005707
5708 This is controlled by the configure argument ``--with-universal-archs``:
5709
5710 - ``--with-universal-archs=all``: install 4-way universal
5711
5712 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5713
5714 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5715
5716 This option should be used in combination with ``--enable-universalsdk=``.
5717
5718 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005768- Issue #1631171: Re-implement the 'warnings' module in C (the
5769 original Python code has been kept as backup). This will allow for
5770 using the 'warning's machinery in such places as the parser where
5771 use of pure Python code is not possible. Both the ``showarning()``
5772 and ``formatwarning()`` gain an optional 'line' argument which is
5773 not called by default for backwards-compatibility reasons. Setting
5774 ``warnings.showwarning()`` to an implementation that lacks support
5775 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005800- The getpass module has been improved on Unix. It now uses /dev/tty
5801 by default and uses stderr instead of stdout. A GetPassWarning is
5802 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005817- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005818 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005838- Issue #2550: The approach used by client/server code for obtaining
5839 ports to listen on in network-oriented tests has been refined in an
5840 effort to facilitate running multiple instances of the entire
5841 regression test suite in parallel without issue.
5842 test_support.bind_port() has been fixed such that it will always
5843 return a unique port -- which wasn't always the case with the
5844 previous implementation, especially if socket options had been set
5845 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5846 new implementation of bind_port() will actually raise an exception
5847 if it is passed an AF_INET/SOCK_STREAM socket with either the
5848 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5849 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5850 the socket it's been passed. This currently only applies to
5851 Windows. This option prevents any other sockets from binding to the
5852 host/port we've bound to, thus removing the possibility of the
5853 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5854 when a second SOCK_STREAM socket binds and accepts to a host/port
5855 that's already been bound by another socket. The optional preferred
5856 port parameter to bind_port() has been removed. Under no
5857 circumstances should tests be hard coding ports!
5858
5859 test_support.find_unused_port() has also been introduced, which will
5860 pass a temporary socket object to bind_port() in order to obtain an
5861 unused port. The temporary socket object is then closed and
5862 deleted, and the port is returned. This method should only be used
5863 for obtaining an unused port in order to pass to an external program
5864 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5865 a parameter to a server-oriented class that doesn't give you direct
5866 access to the underlying socket used.
5867
5868 Finally, test_support.HOST has been introduced, which should be used
5869 for the host argument of any relevant socket calls (i.e. bind and
5870 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005871
5872 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005873 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005874 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5875 test_asynchat and test_socket_ssl.
5876
Georg Brandl3ee81df2008-05-17 18:14:43 +00005877 It is now possible for multiple instances of the regression test
5878 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006157- Added the future_builtins module, which contains hex() and oct().
6158 These are the PEP 3127 version of these functions, designed to be
6159 compatible with the hex() and oct() builtins from Python 3.0. They
6160 differ slightly in their output formats from the existing, unchanged
6161 Python 2.6 builtins. The expected usage of the future_builtins
6162 module is:
6163 from future_builtins import hex, oct
6164
Eric Smith7ef40bf2008-02-20 23:34:22 +00006165- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6166 exponents for exponents with absolute value < 100. Follows C99
6167 standard. This is a change on Windows, which would use 3 digits.
6168 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6169 so that any alterations it does to the resulting string will be
6170 available in stringlib/formatter.h (for float.__format__).
6171
Eric Smith5a3c1352008-02-19 13:21:56 +00006172- Implemented PEP 3101, Advanced String Formatting. This adds a new
6173 builtin format(); a format() method for str and unicode; a
6174 __format__() method to object, str, unicode, int, long, float, and
6175 datetime; the class string.Formatter; and the C API
6176 PyObject_Format().
6177
Georg Brandl3ee81df2008-05-17 18:14:43 +00006178- Fixed several potential crashes, all caused by specially crafted
6179 __del__ methods exploiting objects in temporarily inconsistent
6180 state.

6184 a slot on a registered virtual subclass.

6187 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006188
Georg Brandl3ee81df2008-05-17 18:14:43 +00006189- Clear all free lists during a gc.collect() of the highest generation
6190 in order to allow pymalloc to free more arenas. Python may give back
6191 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006192
Georg Brandl3ee81df2008-05-17 18:14:43 +00006193- Issue #2045: Fix an infinite recursion triggered when printing a
6194 subclass of collections.defaultdict, if its default_factory is set
6195 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006196
Christian Heimesf75dbef2008-02-08 00:11:31 +00006197- Fixed a minor memory leak in dictobject.c. The content of the free
6198 list was not freed on interpreter shutdown.
6199
Georg Brandl21e99f42010-03-07 15:23:59 +00006200- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006201 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006202
Georg Brandl3ee81df2008-05-17 18:14:43 +00006203- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6204 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006205 to compact the internal free lists of pre-allocted ints and floats.
6206
Georg Brandl3ee81df2008-05-17 18:14:43 +00006207- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6208 calls. Python expected the return type int but the fork familie
6209 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006210
Georg Brandl3ee81df2008-05-17 18:14:43 +00006211- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6212 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006213
Georg Brandl3ee81df2008-05-17 18:14:43 +00006214- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6215 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006216
Georg Brandl3ee81df2008-05-17 18:14:43 +00006217- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6218 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00006220- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6221 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006222
Georg Brandl3ee81df2008-05-17 18:14:43 +00006223- Patch #1473257: generator objects gain a gi_code attribute. This is
6224 the same object as the func_code attribute of the function that
6225 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006226
Georg Brandl3ee81df2008-05-17 18:14:43 +00006227- Issue #1920: "while 0" statements were completely removed by the
6228 compiler, even in the presence of an "else" clause, which is
6229 supposed to be run when the condition is false. Now the compiler
6230 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006231
Guido van Rossumeead05f2008-01-24 18:21:02 +00006232- A few crashers fixed: weakref_in_del.py (issue #1377858);
6233 loosing_dict_ref.py (issue #1303614, test67.py);
6234 borrowed_ref_[34].py (not in tracker).
6235
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006236- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006237 suppressed while an extension is loaded by calling SetErrorMode in
6238 dynload_win.c. The error is still reported properly.
6239
Georg Brandl3ee81df2008-05-17 18:14:43 +00006240- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006241 several extension methods and modules do not work without unicode
6242 support.
6243
Georg Brandl26543b12008-01-21 18:36:51 +00006244- Issue #1882: when compiling code from a string, encoding cookies in the
6245 second line of code were not always recognized correctly.
6246
Georg Brandl14404b62008-01-19 19:27:05 +00006247- Issue #1679: "0x" was taken as a valid integer literal.
6248
Georg Brandl6caad7d2008-01-26 14:19:22 +00006249- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006250 added.
6251
Christian Heimesc94e2b52008-01-14 04:13:37 +00006252- sys.float_info / PyFloat_GetInfo: The floating point information
6253 object was converted from a dict to a specialized structseq object.
6254
Georg Brandl3ee81df2008-05-17 18:14:43 +00006255- Patch #1816: Added sys.flags structseq. It exposes the status of
6256 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006257
Georg Brandl3ee81df2008-05-17 18:14:43 +00006258- Objects/structseq.c: Implemented new structseq representation. The
6259 patch makes structseqs (e.g. the return value of os.stat) more
6260 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006261
Georg Brandl3ee81df2008-05-17 18:14:43 +00006262- Patch #1700288: added a type attribute cache that caches method
6263 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006264
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006265- Bug #1776: __import__() no longer accepts filenames on any platform.
6266 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006267
Georg Brandlaed6c662008-01-07 17:25:53 +00006268- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6269
Georg Brandl3ee81df2008-05-17 18:14:43 +00006270- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6271 envvar and sys.dont_write_bytecode attribute. All these can be set
6272 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006273
Georg Brandl3ee81df2008-05-17 18:14:43 +00006274- Improve some exception messages when Windows fails to load an
6275 extension module. Now we get for example '%1 is not a valid Win32
6276 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006277
Georg Brandl3ee81df2008-05-17 18:14:43 +00006278- Bug #1481296: Fixed long(float('nan')) != 0L.

6281 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006282
Christian Heimes0a8143f2007-12-18 23:22:54 +00006283- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006284 and INF. float("nan"), float("inf") and float("-inf") now work on
6285 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006286
Georg Brandl3ee81df2008-05-17 18:14:43 +00006287- Compiler now generates simpler and faster code for dictionary
6288 literals. The oparg for BUILD_MAP now indicates an estimated
6289 dictionary size. There is a new opcode, STORE_MAP, for adding
6290 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006291
Georg Brandl3ee81df2008-05-17 18:14:43 +00006292- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006300- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006301 SystemError.
6302
Nick Coghlanef01d822007-12-03 12:55:17 +00006303- PEP 366: Allow explicit relative imports when executing modules
6304 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00006319- Patch #1739468: Directories and zipfiles containing a __main__.py
6320 file can now be directly executed by passing their name to the
6321 interpreter. The directory/zipfile is automatically inserted as the
6322 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006323
Georg Brandl3ee81df2008-05-17 18:14:43 +00006324- Issue #1265: Fix a problem with sys.settrace, if the tracing
6325 function uses a generator expression when at the same time the
6326 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006327
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006328- sets and frozensets now have an isdisjoint() method.
6329
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006330- optimize the performance of builtin.sum().
6331
Neal Norwitz44f326e2007-10-05 05:29:17 +00006332- Fix warnings found by the new version of the Coverity checker.
6333
Georg Brandl21e99f42010-03-07 15:23:59 +00006334- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006335 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6336 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006337
Georg Brandl3ee81df2008-05-17 18:14:43 +00006338- Issue #1686386: Tuple's tp_repr did not take into account the
6339 possibility of having a self-referential tuple, which is possible
6340 from C code. Nor did object's tp_str consider that a type's tp_str
6341 could do something that could lead to an inifinite recursion.
6342 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6343 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006344
Georg Brandl3ee81df2008-05-17 18:14:43 +00006345- Issue #1164: It was possible to trigger deadlock when using the
6346 'print' statement to write to a file since the GIL was not released
6347 as needed. Now PyObject_Print() does the right thing along with
6348 various tp_print implementations of the built-in types and those in
6349 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006350
Georg Brandl3ee81df2008-05-17 18:14:43 +00006351- Issue #1147: Exceptions were directly allowing string exceptions in
6352 their throw() method even though string exceptions no longer
6353 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006354
Georg Brandl3ee81df2008-05-17 18:14:43 +00006355- Issue #1096: Prevent a segfault from getting the repr of a very
6356 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006357
Brett Cannon1e534b52007-09-07 04:18:30 +00006358- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006359 PyObject_Call() never calling back out to Python code to trigger
6360 recursion depth updates/checks. Required the creation of a static
6361 RuntimeError instance in case normalizing an exception put the
6362 recursion check value past its limit. Fixes crashers
6363 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006364
Georg Brandl3ee81df2008-05-17 18:14:43 +00006365- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006378- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006379 __*__ attributes. (Some already existed, e.g., __doc__ and
6380 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006381
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006382- Add -3 option to the interpreter to warn about features that are
6383 deprecated and will be changed/removed in Python 3.0.
6384
Georg Brandl2134e752007-05-21 20:34:16 +00006385- Patch #1686487: you can now pass any mapping after '**' in function
6386 calls.
6387
Collin Winter62903052007-05-18 23:11:24 +00006388- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006389 "except E as target:". This is to provide forwards compatibility
6390 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00006392- Deprecate BaseException.message as per PEP 352.
6393
Georg Brandl3ee81df2008-05-17 18:14:43 +00006394- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006395 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006396
Vinay Sajip8549ce32007-05-06 17:53:37 +00006397- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006398 setting a plain string, ie don't expand to single letter identifiers.
6399
Raymond Hettinger13936692007-04-11 18:40:58 +00006400- Request #1191699: Slices can now be pickled.
6401
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006402- Request #1193128: str.translate() now allows a None argument for
6403 translations that only remove characters without re-mapping the
6404 remaining characters.
6405
Georg Brandl5cb76c12007-03-21 09:00:39 +00006406- Patch #1682205: a TypeError while unpacking an iterable is no longer
6407 masked by a generic one with the message "unpack non-sequence".
6408
Neal Norwitzaa754b72007-03-21 06:39:48 +00006409- Remove unused file Python/fmod.c.
6410
Guido van Rossum143b5642007-03-23 04:58:42 +00006411- Bug #1683368: The object.__init__() and object.__new__() methods are
6412 now stricter in rejecting excess arguments. The only time when
6413 either allows excess arguments is when it is not overridden and the
6414 other one is. For backwards compatibility, when both are
6415 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006416 warning later). Also, type.__init__() insists on the same signature
6417 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006418
Georg Brandl3ee81df2008-05-17 18:14:43 +00006419- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6420 object to complex using its __complex__() method before falling back
6421 to the __float__() method. Therefore, the functions in the cmath
6422 module now can operate on objects that define a __complex__()

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007395 that the SMTP.starttls() caller no longer needs to call ehlo()
7396 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007397 does not claim to support starttls. Adds the
7398 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7399 Fenner.

7479 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7480 silently miscode subclasses of those types. Now, it raises a
7481 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007482

Georg Brandl3ee81df2008-05-17 18:14:43 +00007497 time so that opening a database previously created with the DB_DUP
7498 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7499 opens. Specifically: dictionary assignment to a DB object will
7500 replace all values for a given key when the database allows
7501 duplicate values. DB users should use DB.put(k, v) when they want
7502 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007503

7509 characters with ASCII value less than 32. Also, it correctly quotes
7510 dots only if they occur on a single line, as opposed to the previous
7511 behavior of quoting dots if they are the second character of any
7512 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007513
