331
R. David Murray20ad3632010-10-01 15:48:49 +0000332- Issue #10004: quoprimime no longer generates a traceback when confronted
333 with invalid characters after '=' in a Q-encoded word.

349 handles non-blocking readinto() returning None correctly.
350

352 SSLSocket.sendto() to match the corresponding socket methods. Also,
353 fix various SSLSocket methods to raise socket.error rather than an

355 by Andrew Bennetts.

363 ZipFile.open()) could return more bytes than requested.
364
Raymond Hettinger20397532010-09-12 02:11:45 +0000365- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
366 This prevents user-created self-referencing ordered dictionaries from
367 becoming permanently uncollectable GC garbage. The downside is that
368 removing __del__ means that the internal doubly-linked list has to wait for
369 GC collection rather than freeing memory immediately when the refcnt drops
370 to zero.
371
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000372- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

375
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000376- Issue #9792: In case of connection failure, socket.create_connection()
377 would swallow the exception and raise a new one, making it impossible
378 to fetch the original errno, or to filter timeout errors. Now the
379 original error is re-raised.
380
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000381- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
382 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
383 be updated back after the system call. Original patch by Brian Brazil.
384

389 ConfigParser.write.
390
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000391- Issue #808164: Fixed socket.close to avoid references to globals, to
392 avoid issues when socket.close is called from a __del__ method.
393

399 falling into recursion.
400
R. David Murray7c4bf552010-08-25 01:45:57 +0000401- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
402 character years even if the message contains RFC822 two character years.
403
Daniel Stutzbach91287322010-08-24 21:09:30 +0000404- Issue #8750: Fixed MutableSet's methods to correctly handle
405 reflexive operations, namely x -= x and x ^= x.
406

416 module now correctly return a set. (Patch by Eli Bendersky.)
417

419 ignored by the buffered IO layer anymore.
420

422 are not held onto after they are deleted elsewhere.
423
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000424- Issue #9626: the view methods for collections.OrderedDict() were returning

437 original read request had been satisfied, which could block indefinitely
438 when the underlying raw IO channel was e.g. a socket. Report and original
439 patch by Jason V. Miller.
440

829 start byte and the continuation byte(s) are now considered invalid, instead
830 of the number of bytes specified by the start byte.
831 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

844 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00001188- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001189 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1190 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1191 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1211Core and Builtins
1212-----------------
1213
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001214- Issue #7301: Add environment variable $PYTHONWARNINGS.
1215
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001216- Issue #8329: Don't return the same lists from select.select when no fds are
1217 changed.
1218
Georg Brandlfee0f442010-05-22 21:26:21 +00001219- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001220 on 64-bit machines. The shift count for either left or right shift is
1221 permitted to be up to sys.maxsize.
1222
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001223- Ensure that tokenization of identifiers is not affected by locale.
1224
Georg Brandlfee0f442010-05-22 21:26:21 +00001225- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001226
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001227- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1228
Georg Brandlfee0f442010-05-22 21:26:21 +00001229- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1230 with a non-empty format string. This is an effort to future-proof user
1231 code. If a derived class does not currently implement __format__ but later
1232 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001233 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001234 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001235
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001236- Issue #8268: Old-style classes (not just instances) now support weak

1248
Victor Stinner66644262010-03-10 22:30:19 +00001249- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001250 (SIGINT). If an error occurs while importing the site module, the error is
1251 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001252 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001265- Issue #8310: Allow dis to examine new style classes.
1266
Georg Brandlfee0f442010-05-22 21:26:21 +00001267- Issue #8257: The Decimal construct now accepts a float instance directly,
1268 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001269
1270 >>> Decimal(1.1)
1271 Decimal('1.100000000000000088817841970012523233890533447265625')
1272
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001273- collections.Counter() now supports a subtract() method.
1274
Georg Brandlfee0f442010-05-22 21:26:21 +00001275- The functools module now has a total_ordering() class decorator to simplify
1276 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001277
Georg Brandlfee0f442010-05-22 21:26:21 +00001278- The functools module also adds cmp_to_key() as a tool to transition old-style
1279 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001280
Georg Brandlfee0f442010-05-22 21:26:21 +00001281- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1282 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001283
Georg Brandlfee0f442010-05-22 21:26:21 +00001284- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1285 InvalidOperation instead of returning False. (Comparisons involving a quiet
1286 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1287 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001288
Georg Brandlfee0f442010-05-22 21:26:21 +00001289- Issue #2531: Comparison operations between floats and Decimal instances now
1290 return a result based on the numeric values of the operands; previously they
1291 returned an arbitrary result based on the relative ordering of id(float) and
1292 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001293
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001294- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001295 argument `-` which tells it to read files to compile from stdin. Each line is
1296 read on demand and the named file is compiled immediately. (Original patch by
1297 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001298
Georg Brandlfee0f442010-05-22 21:26:21 +00001299- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001302- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1303 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001304 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001305
Georg Brandlfee0f442010-05-22 21:26:21 +00001306- Comparisons using one of <, <=, >, >= between a complex instance and a
1307 Fractions instance now raise TypeError instead of returning True/False. This
1308 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1309 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001310

1319
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001320- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001321 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1322 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001323
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001324- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001364- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001365 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1366 log file to compute the next rollover time. If the log file does not exist,
1367 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001368

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001408- Issue #8300: When passing a non-integer argument to struct.pack with any
1409 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00001413- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1414 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1415 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001416 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1417 inconsistent: __int__ was used for some integer codes but not for others, and
1418 the set of integer codes for which it was used differed between native packing
1419 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001631- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
1632 now also used by regrtest to run all the tests in a temporary directory. The
1633 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
1634 Xicluna who helped with the patch.

1651 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001652 library would return a bogus result; on Solaris, it was possible to crash the

1667 and add the additional members returned in an OSVERSIONINFOEX structure. The
1668 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001671- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1672 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1673 returning NULL. The macro now returns a statically allocated empty string
1674 instead.

1684 strings,
1685 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1686 numeric strings corresponding to subnormal values,
1687 (3) a memory leak for some values large enough to cause overflow, and
1688 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001719- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001720 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001721 Also, raise ValueError rather than TypeError when an unknown TIPC address
1722 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001726- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001727 file position when calling `truncate()`. It would previously change the file
1728 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001729 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1730
Georg Brandlba83f822010-03-14 09:50:54 +00001731- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1732 class used to represent files stored inside an archive. The new
1733 implementation is significantly faster and can be wrapped in a
1734 ``io.BufferedReader`` object for more speedups. It also solves an issue
1735 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1736 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00001745
Georg Brandlba83f822010-03-14 09:50:54 +00001746- Issue #7748: Since unicode values are supported for some metadata options in
1747 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1748 encoded string for them. This ensures that the upload and register commands
1749 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001826- The ``__complex__()`` method is now looked up on the class of instances to
1827 make it consistent with other special methods.

1831
Mark Dickinson1b34d252010-01-01 17:27:30 +00001832- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001833 DeprecationWarning when passed a float argument where an integer was expected.
1834 These functions and methods now raise TypeError instead. The majority of the
1835 effects of this change are in the extension modules, but some core functions
1836 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1837 and many unicode/str methods.

1851 of integers: the result of a/b is now correctly rounded for ints a and b (at
1852 least on IEEE 754 platforms), and in particular does not depend on the
1853 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001862 These executables now work properly with the arch(1) command: ``arch -ppc

2004 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002005

Georg Brandlba83f822010-03-14 09:50:54 +00002020- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2021 decimal string that's guaranteed to round back to x under correct rounding
2022 (with round-half-to-even rounding mode). Previously it gave a string based on
2023 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2024 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2025 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002026
Georg Brandlba83f822010-03-14 09:50:54 +00002027- Issue #7117: On almost all platforms: float-to-string and string-to-float
2028 conversions within Python are now correctly rounded. Places these conversions
2029 occur include: str for floats and complex numbers; the float and complex
2030 constructors; old-style and new-style numeric formatting; serialization and
2031 deserialization of floats and complex numbers using marshal, pickle and json;
2032 parsing of float and imaginary literals in Python code; Decimal-to-float
2033 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002034
Georg Brandlba83f822010-03-14 09:50:54 +00002035 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2036 providing correctly-rounded strtod and dtoa C functions. This code is
2037 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2038 the C compiler. There may be a small number of platforms on which correct
2039 operation of this code cannot be guaranteed, so the code is not used: notably,
2040 this applies to platforms where the C double format is not IEEE 754 binary64,
2041 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2042 and Python's configure script is unable to determine how to change the FPU
2043 precision. On these platforms conversions use the platform strtod and dtoa,
2044 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002046- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2047 uses the correctly-rounded string <-> float conversions described above (when
2048 available), and so produces correctly rounded results that will display nicely
2049 under the float repr. There are two related small changes: (1) round now
2050 accepts any class with an ``__index__()`` method for its second argument (but
2051 no longer accepts floats for the second argument), and (2) an excessively
2052 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2053 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002200- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2201 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2202 but with at least one decimal point and with a default precision
2203 of 12. Previously, the behavior the same but with a default precision of 6.
2204 This more closely matches ``str()``, and reduces surprises when adding
2205 alignment flags to the empty presentation type. This also affects the new
2206 complex.__format__ in the same way.
2207
2208- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00002327- Issue #4935: The overflow checking code in the expandtabs() method common to
2328 str, bytes and bytearray could be optimized away by the compiler, letting the
2329 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00002330
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00002331- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2339 collecting the oldest generation) so that allocating lots of objects without

2345
Georg Brandlba83f822010-03-14 09:50:54 +00002346- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2347 existing .py counterpart, override the co_filename attributes of all code
2348 objects if the original filename is obsolete (which can happen if the file has
2349 been renamed, moved, or if it is accessed through different paths). Patch by
2350 Ziga Seilnacht and Jean-Paul Calderone.

2355 file with `str' filename on Windows.
2356
Antoine Pitrouaa687902009-01-01 14:11:22 +00002357- Issue #3680: Reference cycles created through a dict, set or deque iterator

2368
Georg Brandl6425a2f2008-12-28 11:54:53 +00002369- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002370 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002371
Skip Montanarof205c132008-12-23 03:30:15 +00002372- Added test case to ensure attempts to read from a file opened for writing
2373 fail.
2374
Georg Brandlba83f822010-03-14 09:50:54 +00002375- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
2376 elapsed times, not only when some objects are uncollectable/unreachable.
2377 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00002389- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2390 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2391 instances. On a typical machine this saves 3 bytes of memory (on average) per
2392 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002393
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002394- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2395 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2396 instead of throwing a MemoryError.
2397
Georg Brandlba83f822010-03-14 09:50:54 +00002398- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2399 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00002400
Benjamin Petersonc078f922008-11-21 22:27:24 +00002401- Issue #4367: Python would segfault during compiling when the unicodedata
2402 module couldn't be imported and \N escapes were present.
2403
Georg Brandlba83f822010-03-14 09:50:54 +00002404- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2405 file objects with closefd=False. The file descriptor is still kept open but
2406 the file object behaves like a closed file. The ``FileIO`` object also got a
2407 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002408
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002409- Issue #4348: Some bytearray methods returned that didn't cause any change to
2410 the bytearray, returned the same bytearray instead of a copy.
2411
Georg Brandlba83f822010-03-14 09:50:54 +00002412- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002416- Issue #4048: The parser module now correctly validates relative imports.
2417
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002418- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

2420
Georg Brandlba83f822010-03-14 09:50:54 +00002421- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002424- Issue #4209: Enabling unicode_literals and the print_function in the same
2425 __future__ import didn't work.
2426
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002427- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002428 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002429
Georg Brandlba83f822010-03-14 09:50:54 +00002430- On windows, ``os.chdir()`` given unicode was not working if
2431 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2432 this code path is really executed because I cannot move to such directory on
2433 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002434
Georg Brandlba83f822010-03-14 09:50:54 +00002435- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2436 element is temporarily replaced with an equivalent frozenset. But the
2437 eventual KeyError would always report the empty ``frozenset()`` as the missing
2438 key. Now it correctly refers to the initial element.

2456 returned them on 64bit platforms.
2457
Walter Dörwalded960ac2009-05-03 22:36:33 +00002458- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2459 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2460 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2461 of using the replace error handler in PyUnicode_DecodeUTF8().
2462
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002463- Issue #3739: The unicode-internal encoder now reports the number of characters
2464 consumed like any other encoder (instead of the number of bytes).
2465
Georg Brandlba83f822010-03-14 09:50:54 +00002466- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2467 allocator will be automatically disabled when running under Valgrind. This
2468 gives improved memory leak detection when running under Valgrind, while taking
2469 advantage of pymalloc at other times.

3693 threads could return successfully while some Thread objects were still
3694 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00003711- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3712 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003713 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3714 the tests if DISPLAY is defined but can't be used.

3720 import both normal and optimised versions of modules. test_heapq and
3721 test_warnings have been adjusted to use it, tests for other modules with both
3722 C and Python implementations in the stdlib can be adjusted to use it over
3723 time.

3732 should cause a test to be skipped are now done using import_module from test
3733 support, which does the conversion.

3835
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003836- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3837 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3838 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3839 ``printf`` function, whereas PyString_FromFormat has an independent
3840 implementation and uses "%zd" on all platforms for size_t values.
3841 This makes a difference on win64, where ``printf`` needs "%Id" to display
3842 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003844- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3848 object; previously an int would be returned for small values. the __long__
3849 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitrou0668c622008-08-26 22:42:08 +00003862 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3863 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3864 when given a tuple of classes as second argument, were looking up
3865 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3866 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004005What's New in Python 2.6 beta 3?
4006================================
4007
Barry Warsaw07a4a382008-08-21 01:15:08 +00004008*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004009
4010Core and Builtins
4011-----------------
4012
Guido van Rossumf8402962008-08-20 15:01:50 +00004013- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4014 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4015 extensions do not automatically benefit from the class attribute
4016 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4017 to their tp_flags field if they care. This is a backwards
4018 compatibility feature; in 3.0, all types will use the cache by
4019 default.
4020
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004021- Keyword arguments can now follow starred arguments. (``f(a, *args,
4022 keyword=23)`` is now valid syntax.)
4023
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004024- ctypes function pointers that are COM methods have a boolean True
4025 value again.
4026
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004027- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4028 by denying s# to parse objects that have a releasebuffer procedure,
4029 and introducing s*.
4030
Georg Brandl1e13ea92008-08-11 09:07:59 +00004031- Issue #3537: Fix an assertion failure when an empty but presized dict
4032 object was stored in the freelist.
4033
Mark Dickinsonb6467572008-08-04 21:30:09 +00004034- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4035 ValueError consistently across platforms.
4036
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004037- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4038 (64bit Unix, for example), unichr() would truncate its argument and return
4039 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4040
Neal Norwitze7d8be82008-07-31 17:17:14 +00004041- Apply security patches from Apple.
4042
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004043- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4044 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4045
Antoine Pitrou92f82162008-07-25 22:22:08 +00004046- Issue #1819: function calls with several named parameters are now on
4047 average 35% faster (as measured by pybench).
4048
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004049- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4050 the python debugger steps into a class statement: the free variables (local
4051 variables defined in an outer scope) would be deleted from the outer scope.
4052
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004053- Issue #2620: Overflow checking when allocating or reallocating memory
4054 was not always being done properly in some python types and extension
4055 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4056 all been updated to perform better checks and places in the code that
4057 would previously leak memory on the error path when such an allocation
4058 failed have been fixed.

4061-------
4062
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004063- Issue #3612: Added some missing basic types in ctypes.wintypes.
4064
Benjamin Petersone977ad42008-08-20 01:42:01 +00004065- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4066 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4067
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004068- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4069 version reported by these tools does not necessarily follow the python
4070 version numbering scheme, so the module is less strict when parsing it.
4071
Nick Coghlanf70385a2008-08-18 12:42:46 +00004072- Issue #2235: Added Py3k warnings for types which will become unhashable
4073 under the stricter __hash__ inheritance rules in 3.0. Several types
4074 which did not meet the rules for hash invariants and were already
4075 unhashable in 3.0 have now been explicitly flagged as unhashable in
4076 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4077 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4078
Brett Cannon88f801d2008-08-18 00:46:22 +00004079- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4080 imported into the module but exposed as part of the module's API.
4081
Brett Cannon7b96f072008-08-18 00:41:11 +00004082- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4083
Brett Cannon46225e72008-08-18 00:36:52 +00004084- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4085
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004086- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4087
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004088- Issue #3575: Incremental decoder's decode function now takes bytearray
4089 by using 's*' instead of 't#'.
4090
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004091- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004092 fails unicode conversion on 2nd parameter. (windows only)
4093
Georg Brandl222e2082010-08-01 22:27:39 +00004094- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004095 in a redirect.
4096
Brett Cannonabe423e2008-08-16 21:47:07 +00004097- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004098 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004099
Facundo Batistaeb90b782008-08-16 14:44:07 +00004100- Issue #2776: fixed small issue when handling an URL with double slash
4101 after a 302 response in the case of not going through a proxy.
4102
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004103- Issue #2676: in the email package, content-type parsing was hanging on
4104 pathological input because of quadratic or exponential behaviour of a
4105 regular expression.
4106
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004107- Issue #3476: binary buffered reading through the new "io" library is now
4108 thread-safe.
4109
Brett Cannonbf3157b2008-08-14 05:00:03 +00004110- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4111 since mimetools itself is deprecated. Because modules are cached, all
4112 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4113
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004114- Issue #3134: shutil referenced undefined WindowsError symbol.
4115
Robert Schuppenies14646332008-08-10 11:01:53 +00004116- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4117 menu entries were not deleted.
4118
Brett Cannon83e81842008-08-09 23:30:55 +00004119- Copied the implementation of reduce() to _functools.reduce() to have a
4120 version that did not raise a DeprecationWarning under -3.
4121
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004122- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4123 a MemoryError rather than silently stop the iteration.
4124
Guido van Rossum59ce9012008-08-09 14:55:34 +00004125- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4126 to _sre.compile() will now be rejected. This should not affect anybody
4127 since the re.compile() function never generates invalid re-bytecode.
4128
Skip Montanaroa032bf42008-08-08 22:52:51 +00004129- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4130 upon first access it can be automatically initialized from the csv file if
4131 it wasn't initialized during instantiation.
4132
Brett Cannon3aa2a492008-08-06 22:28:09 +00004133- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4134 the reload() built-in has been removed.
4135
Brett Cannon7e30b672008-08-04 21:52:25 +00004136- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004137 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4142 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004143
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004144- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4145 raised an AttributeError.
4146
Benjamin Peterson01a24322008-07-28 23:35:27 +00004147- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004148 asking for a specific length. This problem only affected files opened
4149 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004150
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004151- Issue #3449: Update decimal module to use most recent specification
4152 (v. 1.68) and tests (v. 2.58) from IBM.
4153
Georg Brandl222e2082010-08-01 22:27:39 +00004154- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004155

4158
Georg Brandlf9efabb2008-07-23 15:16:45 +00004159- Deprecate the "ast" parser function aliases.
4160
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004161- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4162
4163- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4164 invalid arguments.
4165
4166- Issue #3302: Fix several crashes when calling locale's gettext functions
4167 with None arguments.
4168
4169- Issue #3389: Allow resolving dotted names for handlers in logging
4170 configuration files.
4171
4172- Deprecate the sunaudio module for removal in Python 3.0.
4173
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004174- Issue #3394: zipfile.writestr sets external attributes when passed a
4175 file name rather than a ZipInfo instance, so files are extracted with
4176 mode 0600 rather than 000 under Unix.
4177
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004178- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4179 argument in python 2.5, this broke code that subclassed Popen to include its
4180 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4191 interaction with the tp_hash slot (added in 2.6b2) are now documented
4192
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004193- Issue #643841: The language reference now provides more detailed
4194 coverage of the lookup process for special methods. The disclaimers
4195 regarding lack of coverage of new-style classes have also been
4196 removed, since the coverage is now fairly reasonable.

4201
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004202*Release date: 17-Jul-2008*
4203
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004204Core and Builtins
4205-----------------
4206
Georg Brandl3e483f62008-07-16 22:57:41 +00004207- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4208 its methods now allow for items objects that can be converted to
4209 an integer using operator.index().
4210
Mark Dickinson64b7e502008-07-16 09:40:03 +00004211- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4212 produced a ValueError instead of giving the correct float.
4213
Eric Smitha5fa5a22008-07-16 00:11:49 +00004214- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4215 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4216
Mark Dickinson7103aa42008-07-15 19:08:33 +00004217- Issue #3008: the float type has a new instance method 'float.hex'
4218 and a new class method 'float.fromhex' to convert floating-point
4219 numbers to and from hexadecimal strings, respectively.
4220
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004221- Issue #2235: __hash__ is once again inherited by default. To allow
4222 collections.Hashable to remain meaningful in the presence of the
4223 default hash implementation (object.__hash__), it is now possible
4224 to explicit block inheritance of hash by setting __hash__=None at
4225 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4226 level.
4227
Nick Coghlanb028f502008-07-13 14:52:36 +00004228- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4229 the parent module cannot be found while performing an absolute import.
4230 This means that an incorrectly defined __package__ attribute will
4231 now only prevent relative imports in that module rather than causing
4232 all imports from that module to fail.
4233
Nick Coghlan14ff9942008-07-08 14:21:42 +00004234- Issue #2517: Allow unicode messages in Exceptions again by correctly
4235 bypassing the instance dictionary when looking up __unicode__ on
4236 new-style classes.
4237
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004238- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4239 set to a custom object whose write() method happens to install
4240 another file in sys.stdout.
4241
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004242- Issue #3088: Corrected a race condition in classes derived from
4243 threading.local: the first member set by a thread could be saved in
4244 another thread's dictionary.
4245
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004246- Issue #3004: Minor change to slice.indices(): the start and stop
4247 arguments are now treated identically, making the behaviour easier
4248 to describe and understand. For example, slice(None, -10,
4249 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4250 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4251 10, -1).
4252
Georg Brandl278fc502008-07-19 12:46:12 +00004253- Issue #3219: Calling a function with repeated keyword arguments,
4254 f(a=2, a=23), would not cause a syntax error. This was a regression
4255 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004257- Issue #2862: Make int and float freelist management consistent with
4258 other freelists. Changes their CompactFreeList apis into
4259 ClearFreeList apis and calls them via gc.collect().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004705 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004706
4707 This is controlled by the configure argument ``--with-universal-archs``:
4708
4709 - ``--with-universal-archs=all``: install 4-way universal
4710
4711 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4712
4713 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4714
4715 This option should be used in combination with ``--enable-universalsdk=``.

4754 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00004756- Added kill, terminate and send_signal(sig) to subprocess.Popen.
4757

Georg Brandl3ee81df2008-05-17 18:14:43 +00004767- Issue #1631171: Re-implement the 'warnings' module in C (the
4768 original Python code has been kept as backup). This will allow for
4769 using the 'warning's machinery in such places as the parser where
4770 use of pure Python code is not possible. Both the ``showarning()``
4771 and ``formatwarning()`` gain an optional 'line' argument which is
4772 not called by default for backwards-compatibility reasons. Setting
4773 ``warnings.showwarning()`` to an implementation that lacks support
4774 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004837- Issue #2550: The approach used by client/server code for obtaining
4838 ports to listen on in network-oriented tests has been refined in an
4839 effort to facilitate running multiple instances of the entire
4840 regression test suite in parallel without issue.
4841 test_support.bind_port() has been fixed such that it will always
4842 return a unique port -- which wasn't always the case with the
4843 previous implementation, especially if socket options had been set
4844 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4845 new implementation of bind_port() will actually raise an exception
4846 if it is passed an AF_INET/SOCK_STREAM socket with either the
4847 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4848 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4849 the socket it's been passed. This currently only applies to
4850 Windows. This option prevents any other sockets from binding to the
4851 host/port we've bound to, thus removing the possibility of the
4852 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4853 when a second SOCK_STREAM socket binds and accepts to a host/port
4854 that's already been bound by another socket. The optional preferred
4855 port parameter to bind_port() has been removed. Under no
4856 circumstances should tests be hard coding ports!
4857
4858 test_support.find_unused_port() has also been introduced, which will
4859 pass a temporary socket object to bind_port() in order to obtain an
4860 unused port. The temporary socket object is then closed and
4861 deleted, and the port is returned. This method should only be used
4862 for obtaining an unused port in order to pass to an external program
4863 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4864 a parameter to a server-oriented class that doesn't give you direct
4865 access to the underlying socket used.
4866
4867 Finally, test_support.HOST has been introduced, which should be used
4868 for the host argument of any relevant socket calls (i.e. bind and
4869 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004870
4871 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004872 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004873 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4874 test_asynchat and test_socket_ssl.
4875
Georg Brandl3ee81df2008-05-17 18:14:43 +00004876 It is now possible for multiple instances of the regression test
4877 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00005081- The bundled libffi copy is now in sync with the recently released
5082 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005083 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
5084 files are used. On all linux systems the --with-system-ffi
5085 configure option defaults to "yes".

Eric Smitha73fbe72008-02-23 03:09:44 +00005156- Added the future_builtins module, which contains hex() and oct().
5157 These are the PEP 3127 version of these functions, designed to be
5158 compatible with the hex() and oct() builtins from Python 3.0. They
5159 differ slightly in their output formats from the existing, unchanged
5160 Python 2.6 builtins. The expected usage of the future_builtins
5161 module is:
5162 from future_builtins import hex, oct
5163
Eric Smith7ef40bf2008-02-20 23:34:22 +00005164- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5165 exponents for exponents with absolute value < 100. Follows C99
5166 standard. This is a change on Windows, which would use 3 digits.
5167 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5168 so that any alterations it does to the resulting string will be
5169 available in stringlib/formatter.h (for float.__format__).
5170
Eric Smith5a3c1352008-02-19 13:21:56 +00005171- Implemented PEP 3101, Advanced String Formatting. This adds a new
5172 builtin format(); a format() method for str and unicode; a
5173 __format__() method to object, str, unicode, int, long, float, and
5174 datetime; the class string.Formatter; and the C API
5175 PyObject_Format().
5176
Georg Brandl3ee81df2008-05-17 18:14:43 +00005177- Fixed several potential crashes, all caused by specially crafted
5178 __del__ methods exploiting objects in temporarily inconsistent
5179 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005180
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005181- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005182 prevent a possible crash: an Abstract Base Class would try to access
5183 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005184

Georg Brandl3ee81df2008-05-17 18:14:43 +00005188- Clear all free lists during a gc.collect() of the highest generation
5189 in order to allow pymalloc to free more arenas. Python may give back
5190 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005191
Georg Brandl3ee81df2008-05-17 18:14:43 +00005192- Issue #2045: Fix an infinite recursion triggered when printing a
5193 subclass of collections.defaultdict, if its default_factory is set
5194 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005195
Christian Heimesf75dbef2008-02-08 00:11:31 +00005196- Fixed a minor memory leak in dictobject.c. The content of the free
5197 list was not freed on interpreter shutdown.
5198
Georg Brandl21e99f42010-03-07 15:23:59 +00005199- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005200 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005201
Georg Brandl3ee81df2008-05-17 18:14:43 +00005202- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5203 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005204 to compact the internal free lists of pre-allocted ints and floats.
5205
Georg Brandl3ee81df2008-05-17 18:14:43 +00005206- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5207 calls. Python expected the return type int but the fork familie
5208 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005209
Georg Brandl3ee81df2008-05-17 18:14:43 +00005210- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5211 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005222- Patch #1473257: generator objects gain a gi_code attribute. This is
5223 the same object as the func_code attribute of the function that
5224 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005225
Georg Brandl3ee81df2008-05-17 18:14:43 +00005226- Issue #1920: "while 0" statements were completely removed by the
5227 compiler, even in the presence of an "else" clause, which is
5228 supposed to be run when the condition is false. Now the compiler
5229 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005230
Guido van Rossumeead05f2008-01-24 18:21:02 +00005231- A few crashers fixed: weakref_in_del.py (issue #1377858);
5232 loosing_dict_ref.py (issue #1303614, test67.py);
5233 borrowed_ref_[34].py (not in tracker).
5234
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005235- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005236 suppressed while an extension is loaded by calling SetErrorMode in

5238
Georg Brandl3ee81df2008-05-17 18:14:43 +00005239- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005240 several extension methods and modules do not work without unicode
5241 support.
5242
Georg Brandl26543b12008-01-21 18:36:51 +00005243- Issue #1882: when compiling code from a string, encoding cookies in the
5244 second line of code were not always recognized correctly.
5245
Georg Brandl14404b62008-01-19 19:27:05 +00005246- Issue #1679: "0x" was taken as a valid integer literal.
5247
Georg Brandl6caad7d2008-01-26 14:19:22 +00005248- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005249 added.
5250
Christian Heimesc94e2b52008-01-14 04:13:37 +00005251- sys.float_info / PyFloat_GetInfo: The floating point information
5252 object was converted from a dict to a specialized structseq object.
5253
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254- Patch #1816: Added sys.flags structseq. It exposes the status of
5255 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005257- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00005283 and INF. float("nan"), float("inf") and float("-inf") now work on
5284 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005285
Georg Brandl3ee81df2008-05-17 18:14:43 +00005286- Compiler now generates simpler and faster code for dictionary
5287 literals. The oparg for BUILD_MAP now indicates an estimated
5288 dictionary size. There is a new opcode, STORE_MAP, for adding
5289 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005318- Patch #1739468: Directories and zipfiles containing a __main__.py
5319 file can now be directly executed by passing their name to the
5320 interpreter. The directory/zipfile is automatically inserted as the
5321 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005323- Issue #1265: Fix a problem with sys.settrace, if the tracing
5324 function uses a generator expression when at the same time the
5325 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005326
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005327- sets and frozensets now have an isdisjoint() method.

5330
Neal Norwitz44f326e2007-10-05 05:29:17 +00005331- Fix warnings found by the new version of the Coverity checker.
5332
Georg Brandl21e99f42010-03-07 15:23:59 +00005333- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005334 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5335 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005336
Georg Brandl3ee81df2008-05-17 18:14:43 +00005337- Issue #1686386: Tuple's tp_repr did not take into account the
5338 possibility of having a self-referential tuple, which is possible
5339 from C code. Nor did object's tp_str consider that a type's tp_str
5340 could do something that could lead to an inifinite recursion.
5341 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5342 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005343
Georg Brandl3ee81df2008-05-17 18:14:43 +00005344- Issue #1164: It was possible to trigger deadlock when using the
5345 'print' statement to write to a file since the GIL was not released
5346 as needed. Now PyObject_Print() does the right thing along with
5347 various tp_print implementations of the built-in types and those in
5348 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005349
Georg Brandl3ee81df2008-05-17 18:14:43 +00005350- Issue #1147: Exceptions were directly allowing string exceptions in
5351 their throw() method even though string exceptions no longer
5352 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005353
Georg Brandl3ee81df2008-05-17 18:14:43 +00005354- Issue #1096: Prevent a segfault from getting the repr of a very
5355 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005356
Brett Cannon1e534b52007-09-07 04:18:30 +00005357- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005358 PyObject_Call() never calling back out to Python code to trigger
5359 recursion depth updates/checks. Required the creation of a static
5360 RuntimeError instance in case normalizing an exception put the
5361 recursion check value past its limit. Fixes crashers
5362 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005363

Neal Norwitz0ac60192007-05-27 04:08:54 +00005377- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005378 __*__ attributes. (Some already existed, e.g., __doc__ and
5379 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005380
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005381- Add -3 option to the interpreter to warn about features that are
5382 deprecated and will be changed/removed in Python 3.0.
5383
Georg Brandl2134e752007-05-21 20:34:16 +00005384- Patch #1686487: you can now pass any mapping after '**' in function
5385 calls.
5386
Collin Winter62903052007-05-18 23:11:24 +00005387- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005388 "except E as target:". This is to provide forwards compatibility
5389 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005390
Brett Cannon229cee22007-05-05 01:34:02 +00005391- Deprecate BaseException.message as per PEP 352.
5392
Georg Brandl3ee81df2008-05-17 18:14:43 +00005393- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005394 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005395
Vinay Sajip8549ce32007-05-06 17:53:37 +00005396- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005397 setting a plain string, ie don't expand to single letter identifiers.
5398
Raymond Hettinger13936692007-04-11 18:40:58 +00005399- Request #1191699: Slices can now be pickled.
5400
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005401- Request #1193128: str.translate() now allows a None argument for
5402 translations that only remove characters without re-mapping the
5403 remaining characters.
5404
Georg Brandl5cb76c12007-03-21 09:00:39 +00005405- Patch #1682205: a TypeError while unpacking an iterable is no longer
5406 masked by a generic one with the message "unpack non-sequence".
5407
Neal Norwitzaa754b72007-03-21 06:39:48 +00005408- Remove unused file Python/fmod.c.
5409
Guido van Rossum143b5642007-03-23 04:58:42 +00005410- Bug #1683368: The object.__init__() and object.__new__() methods are
5411 now stricter in rejecting excess arguments. The only time when
5412 either allows excess arguments is when it is not overridden and the
5413 other one is. For backwards compatibility, when both are
5414 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005415 warning later). Also, type.__init__() insists on the same signature
5416 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005417
Georg Brandl3ee81df2008-05-17 18:14:43 +00005418- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5419 object to complex using its __complex__() method before falling back
5420 to the __float__() method. Therefore, the functions in the cmath
5421 module now can operate on objects that define a __complex__()
5422 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005423
Georg Brandl3ee81df2008-05-17 18:14:43 +00005424- Patch #1623563: allow __class__ assignment for classes with
5425 __slots__. The old and the new class are still required to have the
5426 same slot names.

5432 ``object.__reduce_ex__()`` is called with an object that is faking
5433 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005434
Georg Brandl3ee81df2008-05-17 18:14:43 +00005435- Patch #1680015: Don't modify __slots__ tuple if it contains an

5439
Georg Brandl7b9c5552007-03-12 14:30:05 +00005440- Bug #1678647: write a newline after printing an exception in any
5441 case, even when converting the value to a string failed.
5442
Georg Brandl871f1bc2007-03-12 13:17:36 +00005443- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005444 its argument, if it exists. If not, it will work like before. This
5445 allows customizing the output of dir() in the presence of a
5446 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005454- Patch #1491866: change the complex() constructor to allow
5455 parthensized forms. This means complex(repr(x)) now works instead of
5456 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005457
Georg Brandlaa2321b2007-03-07 00:40:28 +00005458- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005459 makes the filenames the warning module prints much more sensible
5460 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005461

5463 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005464 variable is given, but break into the interactive interpreter just
5465 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00005472
Georg Brandl0fca97a2007-03-05 22:28:08 +00005473- Patch #1674228: when assigning a slice (old-style), check for the
5474 sq_ass_slice instead of the sq_slice slot.
5475
Georg Brandl3ee81df2008-05-17 18:14:43 +00005476- When printing an unraisable error, don't print exceptions. before
5477 the name. This duplicates the behavior whening normally printing
5478 exceptions.

6106 -- the failure just occurred later, with a more cumbersome
6107 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006388- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6389 with RFC 3207 and forgets any knowledge obtained from the server not
6390 obtained from the TLS negotiation itself. Patch contributed by Bill
6391 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006392
Georg Brandl3ee81df2008-05-17 18:14:43 +00006393- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006394 that the SMTP.starttls() caller no longer needs to call ehlo()
6395 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006396 does not claim to support starttls. Adds the
6397 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6478 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6479 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00006481

Georg Brandl3ee81df2008-05-17 18:14:43 +00006496 time so that opening a database previously created with the DB_DUP
6497 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6498 opens. Specifically: dictionary assignment to a DB object will
6499 replace all values for a given key when the database allows
6500 duplicate values. DB users should use DB.put(k, v) when they want
6501 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006502

6508 characters with ASCII value less than 32. Also, it correctly quotes
6509 dots only if they occur on a single line, as opposed to the previous
6510 behavior of quoting dots if they are the second character of any
6511 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006512

6834-----
6835
Georg Brandl3ee81df2008-05-17 18:14:43 +00006836- Unified naming convention for free lists and their limits. All free
6837 lists in Object/ are named ``free_list``, the counter ``numfree``

6839 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006840
Georg Brandl3ee81df2008-05-17 18:14:43 +00006841- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6842 to ``PyTuple_SetItem``, it can be used to populate a brand new

6855
Georg Brandl3ee81df2008-05-17 18:14:43 +00006856- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6857 of w# format code incorrectly truncated the length to an int, even
6858 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6859 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006860
Georg Brandl3ee81df2008-05-17 18:14:43 +00006861- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6878
6879- Fix some leftovers from the conversion from int to Py_ssize_t
6880 (relevant to strings and sequences of more than 2**31 items).
6881
6882- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6883 outside of pystate.c and should not be necessary.
6884
Georg Brandl3ee81df2008-05-17 18:14:43 +00006885- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6886 absolute imports. In earlier versions they might have used relative
6887 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006888
Georg Brandl3ee81df2008-05-17 18:14:43 +00006889- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6890 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006891
Georg Brandl3ee81df2008-05-17 18:14:43 +00006892- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006899- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6900 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6901 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6902 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006903

6916
Georg Brandl3ee81df2008-05-17 18:14:43 +00006917- Removed the macfs module. It had been deprecated since Python 2.5.
6918 This lead to the deprecation of macostools.touched() as it relied
6919 solely on macfs and was a no-op under OS X.
