Raymond Hettinger74f869e2010-09-13 22:14:36 +0000603- Issue #9826: OrderedDict.__repr__ can now handle self-referential
604 values: d['x'] = d.
605
Victor Stinner8fc843b2010-09-17 23:35:50 +0000606- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinner46287f52010-09-13 20:31:34 +0000607
Antoine Pitroue4195e82010-09-12 14:56:27 +0000608- Issue #9837: The read() method of ZipExtFile objects (as returned by
609 ZipFile.open()) could return more bytes than requested.
610
Raymond Hettinger20397532010-09-12 02:11:45 +0000611- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
612 This prevents user-created self-referencing ordered dictionaries from
613 becoming permanently uncollectable GC garbage. The downside is that
614 removing __del__ means that the internal doubly-linked list has to wait for
615 GC collection rather than freeing memory immediately when the refcnt drops
616 to zero.
617
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000618- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000619 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000620 value.
621
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000622- Issue #9792: In case of connection failure, socket.create_connection()
623 would swallow the exception and raise a new one, making it impossible
624 to fetch the original errno, or to filter timeout errors. Now the
625 original error is re-raised.
626
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000627- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
628 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
629 be updated back after the system call. Original patch by Brian Brazil.
630
Antoine Pitroudca9de92010-09-04 17:52:26 +0000631- Issue #1100562: Fix deep-copying of objects derived from the list and

635 ConfigParser.write.
636
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000637- Issue #808164: Fixed socket.close to avoid references to globals, to
638 avoid issues when socket.close is called from a __del__ method.
639
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000640- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
641 can be set to False to turn off the previously undocumented 'popularity'
642 heuristic. Patch by Terry Reedy and Eli Bendersky
643
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000644- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
645 falling into recursion.
646
R. David Murray7c4bf552010-08-25 01:45:57 +0000647- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
648 character years even if the message contains RFC822 two character years.
649
Daniel Stutzbach91287322010-08-24 21:09:30 +0000650- Issue #8750: Fixed MutableSet's methods to correctly handle
651 reflexive operations, namely x -= x and x ^= x.
652
Victor Stinnercaafd772010-09-08 10:51:01 +0000653- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

657 errors.

662 module now correctly return a set. (Patch by Eli Bendersky.)
663
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000664- Issue #9617: Signals received during a low-level write operation aren't
665 ignored by the buffered IO layer anymore.
666
Benjamin Peterson52c36052010-08-21 03:03:22 +0000667- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
668 are not held onto after they are deleted elsewhere.
669
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000670- Issue #9626: the view methods for collections.OrderedDict() were returning
671 the unordered versions inherited from dict. Those methods are now
672 overridden to provide ordered views.
673
Éric Araujo0389ae62010-08-14 03:07:46 +0000674- Issue #8688: MANIFEST files created by distutils now include a magic
675 comment indicating they are generated. Manually maintained MANIFESTs
676 without this marker will not be overwritten or removed.
677
Antoine Pitroue1436d12010-08-12 15:25:51 +0000678- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
679 and a BadZipfile error is raised if it doesn't match (as used to be the
680 case in Python 2.5 and earlier).
681
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000682- Issue #9550: a BufferedReader could issue an additional read when the
683 original read request had been satisfied, which could block indefinitely
684 when the underlying raw IO channel was e.g. a socket. Report and original
685 patch by Jason V. Miller.
686
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000687- Issue #9551: Don't raise TypeError when setting the value to None for
688 SafeConfigParser instances constructed with allow_no_value == True.
689
Antoine Pitrou8cdede42010-08-10 00:04:13 +0000690- Issue #6915: Under Windows, os.listdir() didn't release the Global
691 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
692
Antoine Pitrou99009162010-08-09 22:51:24 +0000693- Issue #3757: thread-local objects now support cyclic garbage collection.
694 Thread-local objects involved in reference cycles will be deallocated

706 This is how it is supposed to work, wget and curl do the same. Previous
707 behavior was wrong.
708
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +0000709- Issue #2944: asyncore doesn't handle connection refused correctly.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001075- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1076 start byte and the continuation byte(s) are now considered invalid, instead
1077 of the number of bytes specified by the start byte.
1078 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1079 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1080 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

1090 objects. (1) The comparison could incorrectly return True in some cases
1091 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1092 (2) The comparison raised an OverflowError for large integers, leading

1288 operation raises multiple signals and more than one of those signals is
1289 trapped, the specification determines the order in which the signals should be
1290 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00001435- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001436 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1437 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1438 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1458Core and Builtins
1459-----------------
1460
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001461- Issue #7301: Add environment variable $PYTHONWARNINGS.
1462
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001463- Issue #8329: Don't return the same lists from select.select when no fds are
1464 changed.
1465
Georg Brandlfee0f442010-05-22 21:26:21 +00001466- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001467 on 64-bit machines. The shift count for either left or right shift is
1468 permitted to be up to sys.maxsize.
1469
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001470- Ensure that tokenization of identifiers is not affected by locale.
1471
Georg Brandlfee0f442010-05-22 21:26:21 +00001472- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001473
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001474- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1475
Georg Brandlfee0f442010-05-22 21:26:21 +00001476- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1477 with a non-empty format string. This is an effort to future-proof user
1478 code. If a derived class does not currently implement __format__ but later
1479 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001480 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001481 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001482
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001483- Issue #8268: Old-style classes (not just instances) now support weak
1484 references.
1485
Georg Brandlfee0f442010-05-22 21:26:21 +00001486- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1487 is set.

Victor Stinner66644262010-03-10 22:30:19 +00001496- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001497 (SIGINT). If an error occurs while importing the site module, the error is
1498 printed and Python exits. Initialize the GIL before importing the site

Antoine Pitrouf9de5342010-04-05 21:35:07 +00001508- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001509 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001512- Issue #8310: Allow dis to examine new style classes.
1513
Georg Brandlfee0f442010-05-22 21:26:21 +00001514- Issue #8257: The Decimal construct now accepts a float instance directly,
1515 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001516
1517 >>> Decimal(1.1)
1518 Decimal('1.100000000000000088817841970012523233890533447265625')
1519
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001520- collections.Counter() now supports a subtract() method.
1521
Georg Brandlfee0f442010-05-22 21:26:21 +00001522- The functools module now has a total_ordering() class decorator to simplify
1523 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001524
Georg Brandlfee0f442010-05-22 21:26:21 +00001525- The functools module also adds cmp_to_key() as a tool to transition old-style
1526 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001527
Georg Brandlfee0f442010-05-22 21:26:21 +00001528- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1529 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001530
Georg Brandlfee0f442010-05-22 21:26:21 +00001531- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1532 InvalidOperation instead of returning False. (Comparisons involving a quiet
1533 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1534 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001535
Georg Brandlfee0f442010-05-22 21:26:21 +00001536- Issue #2531: Comparison operations between floats and Decimal instances now
1537 return a result based on the numeric values of the operands; previously they
1538 returned an arbitrary result based on the relative ordering of id(float) and
1539 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001540
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001541- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001542 argument `-` which tells it to read files to compile from stdin. Each line is
1543 read on demand and the named file is compiled immediately. (Original patch by
1544 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001545
Georg Brandlfee0f442010-05-22 21:26:21 +00001546- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1547 function like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +00001548
Florent Xicluna58b65662010-03-30 16:29:03 +00001549- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1550 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001551 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001552
Georg Brandlfee0f442010-05-22 21:26:21 +00001553- Comparisons using one of <, <=, >, >= between a complex instance and a
1554 Fractions instance now raise TypeError instead of returning True/False. This
1555 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1556 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001557
Michael Foorde6410c52010-03-29 20:04:23 +00001558- Addition of ``WeakSet`` to the ``weakref`` module.

1566
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001567- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001568 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1569 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001570
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001571- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1572 deprecated.
1573
Georg Brandlfee0f442010-05-22 21:26:21 +00001574- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1575 is running in WOW64 mode on 64 bit Windows.

1597 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00001598
Matthias Klose8b411682010-03-16 10:48:52 +00001599- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
1600 with Tcl/Tk-8.5.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001611- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001612 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1613 log file to compute the next rollover time. If the log file does not exist,
1614 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001615
Georg Brandlba83f822010-03-14 09:50:54 +00001616- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001624- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1625 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1626 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001655- Issue #8300: When passing a non-integer argument to struct.pack with any
1656 integer format code, struct.pack first attempts to convert the non-integer
1657 using its __index__ method. If that method is non-existent or raises
1658 TypeError it goes on to try the __int__ method, as described below.
1659
Georg Brandlba83f822010-03-14 09:50:54 +00001660- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1661 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1662 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001663 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1664 inconsistent: __int__ was used for some integer codes but not for others, and
1665 the set of integer codes for which it was used differed between native packing

1898 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001899 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00001974 file position when calling `truncate()`. It would previously change the file
1975 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001976 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1979 class used to represent files stored inside an archive. The new
1980 implementation is significantly faster and can be wrapped in a
1981 ``io.BufferedReader`` object for more speedups. It also solves an issue
1982 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1995 encoded string for them. This ensures that the upload and register commands
1996 send the correct values to PyPI without any error.

2078
Mark Dickinson1b34d252010-01-01 17:27:30 +00002079- Issue #5080: A number of functions and methods previously produced a

2083 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2084 and many unicode/str methods.

2108
Georg Brandlba83f822010-03-14 09:50:54 +00002109 These executables now work properly with the arch(1) command: ``arch -ppc
2110 python`` will start a universal binary version of python in PPC mode (unlike

2251 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002252
Georg Brandlba83f822010-03-14 09:50:54 +00002253- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2254 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002255
Georg Brandlba83f822010-03-14 09:50:54 +00002256- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002266
Georg Brandlba83f822010-03-14 09:50:54 +00002267- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2268 decimal string that's guaranteed to round back to x under correct rounding
2269 (with round-half-to-even rounding mode). Previously it gave a string based on
2270 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2271 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2272 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002273
Georg Brandlba83f822010-03-14 09:50:54 +00002274- Issue #7117: On almost all platforms: float-to-string and string-to-float
2275 conversions within Python are now correctly rounded. Places these conversions
2276 occur include: str for floats and complex numbers; the float and complex
2277 constructors; old-style and new-style numeric formatting; serialization and
2278 deserialization of floats and complex numbers using marshal, pickle and json;
2279 parsing of float and imaginary literals in Python code; Decimal-to-float
2280 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002281
Georg Brandlba83f822010-03-14 09:50:54 +00002282 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2283 providing correctly-rounded strtod and dtoa C functions. This code is
2284 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2285 the C compiler. There may be a small number of platforms on which correct
2286 operation of this code cannot be guaranteed, so the code is not used: notably,
2287 this applies to platforms where the C double format is not IEEE 754 binary64,
2288 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2289 and Python's configure script is unable to determine how to change the FPU
2290 precision. On these platforms conversions use the platform strtod and dtoa,
2291 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002292
Georg Brandlba83f822010-03-14 09:50:54 +00002293- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2294 uses the correctly-rounded string <-> float conversions described above (when
2295 available), and so produces correctly rounded results that will display nicely
2296 under the float repr. There are two related small changes: (1) round now
2297 accepts any class with an ``__index__()`` method for its second argument (but
2298 no longer accepts floats for the second argument), and (2) an excessively
2299 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2300 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002442
Georg Brandlba83f822010-03-14 09:50:54 +00002443 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2444 (2) parsing of strings representing infinities and nans was locale aware; and
2445 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002447- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2448 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2449 but with at least one decimal point and with a default precision
2450 of 12. Previously, the behavior the same but with a default precision of 6.
2451 This more closely matches ``str()``, and reduces surprises when adding
2452 alignment flags to the empty presentation type. This also affects the new
2453 complex.__format__ in the same way.
2454
2455- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2456 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00002518 untrackable objects are not tracked by the garbage collector. This can reduce

2527 internal representation of integers, for performance reasons. Base 2**30 is
2528 enabled by default on 64-bit machines. Add --enable-big-digits option to

2615
Georg Brandl6425a2f2008-12-28 11:54:53 +00002616- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002617 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002618
Skip Montanarof205c132008-12-23 03:30:15 +00002619- Added test case to ensure attempts to read from a file opened for writing
2620 fail.
2621
Georg Brandlba83f822010-03-14 09:50:54 +00002622- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
2623 elapsed times, not only when some objects are uncollectable/unreachable.

Georg Brandlba83f822010-03-14 09:50:54 +00002636- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2637 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2638 instances. On a typical machine this saves 3 bytes of memory (on average) per
2639 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002641- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2642 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2643 instead of throwing a MemoryError.
2644
Georg Brandlba83f822010-03-14 09:50:54 +00002645- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00002648- Issue #4367: Python would segfault during compiling when the unicodedata

2650
Georg Brandlba83f822010-03-14 09:50:54 +00002651- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2652 file objects with closefd=False. The file descriptor is still kept open but
2653 the file object behaves like a closed file. The ``FileIO`` object also got a
2654 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002656- Issue #4348: Some bytearray methods returned that didn't cause any change to
2657 the bytearray, returned the same bytearray instead of a copy.
2658
Georg Brandlba83f822010-03-14 09:50:54 +00002659- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002671- Issue #4209: Enabling unicode_literals and the print_function in the same
2672 __future__ import didn't work.
2673
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002674- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002675 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002676
Georg Brandlba83f822010-03-14 09:50:54 +00002677- On windows, ``os.chdir()`` given unicode was not working if
2678 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2679 this code path is really executed because I cannot move to such directory on
2680 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002681
Georg Brandlba83f822010-03-14 09:50:54 +00002682- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2683 element is temporarily replaced with an equivalent frozenset. But the
2684 eventual KeyError would always report the empty ``frozenset()`` as the missing
2685 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002702- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2703 returned them on 64bit platforms.
2704
Walter Dörwalded960ac2009-05-03 22:36:33 +00002705- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2706 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2707 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2708 of using the replace error handler in PyUnicode_DecodeUTF8().
2709
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002710- Issue #3739: The unicode-internal encoder now reports the number of characters
2711 consumed like any other encoder (instead of the number of bytes).
2712
Georg Brandlba83f822010-03-14 09:50:54 +00002713- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2714 allocator will be automatically disabled when running under Valgrind. This
2715 gives improved memory leak detection when running under Valgrind, while taking
2716 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003960 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3961 the tests if DISPLAY is defined but can't be used.

3965
Georg Brandlba83f822010-03-14 09:50:54 +00003966- Issue #5354: New test support function import_fresh_module() makes it easy to
3967 import both normal and optimised versions of modules. test_heapq and
3968 test_warnings have been adjusted to use it, tests for other modules with both
3969 C and Python implementations in the stdlib can be adjusted to use it over
3970 time.

3980 support, which does the conversion.

4082
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004083- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4084 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4085 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4086 ``printf`` function, whereas PyString_FromFormat has an independent
4087 implementation and uses "%zd" on all platforms for size_t values.
4088 This makes a difference on win64, where ``printf`` needs "%Id" to display
4089 64bit values.

4095 object; previously an int would be returned for small values. the __long__
4096 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004106 was correctly parsed but parsing of subsequent arguments failed.
4107
Vinay Sajip35e3b032008-09-01 14:33:59 +00004108- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004109 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4110 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4111 when given a tuple of classes as second argument, were looking up
4112 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4113 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004252What's New in Python 2.6 beta 3?
4253================================
4254
Barry Warsaw07a4a382008-08-21 01:15:08 +00004255*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004256
4257Core and Builtins
4258-----------------
4259
Guido van Rossumf8402962008-08-20 15:01:50 +00004260- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4261 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4262 extensions do not automatically benefit from the class attribute
4263 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4264 to their tp_flags field if they care. This is a backwards
4265 compatibility feature; in 3.0, all types will use the cache by
4266 default.
4267
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004268- Keyword arguments can now follow starred arguments. (``f(a, *args,
4269 keyword=23)`` is now valid syntax.)
4270
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004271- ctypes function pointers that are COM methods have a boolean True
4272 value again.
4273
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004274- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4275 by denying s# to parse objects that have a releasebuffer procedure,
4276 and introducing s*.
4277
Georg Brandl1e13ea92008-08-11 09:07:59 +00004278- Issue #3537: Fix an assertion failure when an empty but presized dict
4279 object was stored in the freelist.
4280
Mark Dickinsonb6467572008-08-04 21:30:09 +00004281- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4282 ValueError consistently across platforms.
4283
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004284- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4285 (64bit Unix, for example), unichr() would truncate its argument and return
4286 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4287
Neal Norwitze7d8be82008-07-31 17:17:14 +00004288- Apply security patches from Apple.
4289
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004290- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4291 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4292
Antoine Pitrou92f82162008-07-25 22:22:08 +00004293- Issue #1819: function calls with several named parameters are now on
4294 average 35% faster (as measured by pybench).
4295
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004296- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4297 the python debugger steps into a class statement: the free variables (local
4298 variables defined in an outer scope) would be deleted from the outer scope.
4299
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004300- Issue #2620: Overflow checking when allocating or reallocating memory
4301 was not always being done properly in some python types and extension
4302 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4303 all been updated to perform better checks and places in the code that
4304 would previously leak memory on the error path when such an allocation
4305 failed have been fixed.
4306
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004307Library
4308-------
4309
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004310- Issue #3612: Added some missing basic types in ctypes.wintypes.
4311
Benjamin Petersone977ad42008-08-20 01:42:01 +00004312- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4313 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4314
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004315- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4316 version reported by these tools does not necessarily follow the python
4317 version numbering scheme, so the module is less strict when parsing it.
4318
Nick Coghlanf70385a2008-08-18 12:42:46 +00004319- Issue #2235: Added Py3k warnings for types which will become unhashable
4320 under the stricter __hash__ inheritance rules in 3.0. Several types
4321 which did not meet the rules for hash invariants and were already
4322 unhashable in 3.0 have now been explicitly flagged as unhashable in
4323 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4324 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4325
Brett Cannon88f801d2008-08-18 00:46:22 +00004326- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4327 imported into the module but exposed as part of the module's API.
4328
Brett Cannon7b96f072008-08-18 00:41:11 +00004329- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4330
Brett Cannon46225e72008-08-18 00:36:52 +00004331- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4332
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004333- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4334
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004335- Issue #3575: Incremental decoder's decode function now takes bytearray
4336 by using 's*' instead of 't#'.
4337
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004338- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004339 fails unicode conversion on 2nd parameter. (windows only)
4340
Georg Brandl222e2082010-08-01 22:27:39 +00004341- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004342 in a redirect.
4343
Brett Cannonabe423e2008-08-16 21:47:07 +00004344- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004345 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004346
Facundo Batistaeb90b782008-08-16 14:44:07 +00004347- Issue #2776: fixed small issue when handling an URL with double slash
4348 after a 302 response in the case of not going through a proxy.
4349
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004350- Issue #2676: in the email package, content-type parsing was hanging on
4351 pathological input because of quadratic or exponential behaviour of a
4352 regular expression.
4353
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004354- Issue #3476: binary buffered reading through the new "io" library is now
4355 thread-safe.
4356
Brett Cannonbf3157b2008-08-14 05:00:03 +00004357- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4358 since mimetools itself is deprecated. Because modules are cached, all
4359 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4360
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004361- Issue #3134: shutil referenced undefined WindowsError symbol.
4362
Robert Schuppenies14646332008-08-10 11:01:53 +00004363- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4364 menu entries were not deleted.
4365
Brett Cannon83e81842008-08-09 23:30:55 +00004366- Copied the implementation of reduce() to _functools.reduce() to have a
4367 version that did not raise a DeprecationWarning under -3.
4368
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004369- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4370 a MemoryError rather than silently stop the iteration.
4371
Guido van Rossum59ce9012008-08-09 14:55:34 +00004372- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4373 to _sre.compile() will now be rejected. This should not affect anybody
4374 since the re.compile() function never generates invalid re-bytecode.
4375
Skip Montanaroa032bf42008-08-08 22:52:51 +00004376- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4377 upon first access it can be automatically initialized from the csv file if
4378 it wasn't initialized during instantiation.
4379
Brett Cannon3aa2a492008-08-06 22:28:09 +00004380- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4381 the reload() built-in has been removed.
4382
Brett Cannon7e30b672008-08-04 21:52:25 +00004383- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004384 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004385 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4386 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4387 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4388 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4389 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004390
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004391- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4392 raised an AttributeError.
4393
Benjamin Peterson01a24322008-07-28 23:35:27 +00004394- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004395 asking for a specific length. This problem only affected files opened
4396 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004397
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004398- Issue #3449: Update decimal module to use most recent specification
4399 (v. 1.68) and tests (v. 2.58) from IBM.
4400
Georg Brandl222e2082010-08-01 22:27:39 +00004401- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004402

4405
Georg Brandlf9efabb2008-07-23 15:16:45 +00004406- Deprecate the "ast" parser function aliases.
4407
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004408- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4409
4410- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4411 invalid arguments.
4412
4413- Issue #3302: Fix several crashes when calling locale's gettext functions
4414 with None arguments.
4415
4416- Issue #3389: Allow resolving dotted names for handlers in logging
4417 configuration files.
4418

4420
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004421- Issue #3394: zipfile.writestr sets external attributes when passed a
4422 file name rather than a ZipInfo instance, so files are extracted with
4423 mode 0600 rather than 000 under Unix.
4424
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004425- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4426 argument in python 2.5, this broke code that subclassed Popen to include its
4427 own poll method. Fixed my moving _deadstate to an _internal_poll method.
4428
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00004429Build
4430-----

4435-------------
4436
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004437- Issue #2235: the C API function PyObject_HashNotImplemented and its
4438 interaction with the tp_hash slot (added in 2.6b2) are now documented
4439
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004440- Issue #643841: The language reference now provides more detailed
4441 coverage of the lookup process for special methods. The disclaimers
4442 regarding lack of coverage of new-style classes have also been
4443 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004446What's New in Python 2.6 beta 2?
4447================================
4448
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004449*Release date: 17-Jul-2008*
4450
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004451Core and Builtins
4452-----------------
4453
Georg Brandl3e483f62008-07-16 22:57:41 +00004454- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4455 its methods now allow for items objects that can be converted to
4456 an integer using operator.index().
4457
Mark Dickinson64b7e502008-07-16 09:40:03 +00004458- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4459 produced a ValueError instead of giving the correct float.
4460
Eric Smitha5fa5a22008-07-16 00:11:49 +00004461- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4462 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4463
Mark Dickinson7103aa42008-07-15 19:08:33 +00004464- Issue #3008: the float type has a new instance method 'float.hex'
4465 and a new class method 'float.fromhex' to convert floating-point
4466 numbers to and from hexadecimal strings, respectively.
4467
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004468- Issue #2235: __hash__ is once again inherited by default. To allow
4469 collections.Hashable to remain meaningful in the presence of the
4470 default hash implementation (object.__hash__), it is now possible
4471 to explicit block inheritance of hash by setting __hash__=None at
4472 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4473 level.
4474
Nick Coghlanb028f502008-07-13 14:52:36 +00004475- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4476 the parent module cannot be found while performing an absolute import.
4477 This means that an incorrectly defined __package__ attribute will
4478 now only prevent relative imports in that module rather than causing
4479 all imports from that module to fail.
4480
Nick Coghlan14ff9942008-07-08 14:21:42 +00004481- Issue #2517: Allow unicode messages in Exceptions again by correctly
4482 bypassing the instance dictionary when looking up __unicode__ on
4483 new-style classes.
4484
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004485- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4486 set to a custom object whose write() method happens to install
4487 another file in sys.stdout.
4488
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004489- Issue #3088: Corrected a race condition in classes derived from
4490 threading.local: the first member set by a thread could be saved in
4491 another thread's dictionary.
4492
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004493- Issue #3004: Minor change to slice.indices(): the start and stop
4494 arguments are now treated identically, making the behaviour easier
4495 to describe and understand. For example, slice(None, -10,
4496 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4497 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4498 10, -1).
4499
Georg Brandl278fc502008-07-19 12:46:12 +00004500- Issue #3219: Calling a function with repeated keyword arguments,
4501 f(a=2, a=23), would not cause a syntax error. This was a regression
4502 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004503
Georg Brandl278fc502008-07-19 12:46:12 +00004504- Issue #2862: Make int and float freelist management consistent with
4505 other freelists. Changes their CompactFreeList apis into
4506 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004507

4510
Thomas Heller57adf222008-08-14 19:10:48 +00004511- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4512 api functions without holding the GIL, which could lead to a fatal
4513 error when they failed.
4514
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004515- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004523- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4524 ForkingPickler.register() to resolve conflict with ctypes.
4525
Vinay Sajip51e65192008-07-18 09:01:10 +00004526- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004527
Thomas Heller880f5292008-07-15 19:39:38 +00004528- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4529 a valid dlerror() message.
4530
Thomas Heller2bad6572008-07-15 17:19:50 +00004531- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4532 incomplete structure was created.
4533
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004534- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00004536- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4537

4949
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004950- On MacOS X it is now possible to install the framework in 64-bit
4951 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004952 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004953
4954 This is controlled by the configure argument ``--with-universal-archs``:
4955
4956 - ``--with-universal-archs=all``: install 4-way universal
4957
4958 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4959
4960 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4961
4962 This option should be used in combination with ``--enable-universalsdk=``.
4963
4964 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5001 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005002
Christian Heimese74c8f22008-04-19 02:23:57 +00005003- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5004
Georg Brandl3ee81df2008-05-17 18:14:43 +00005005- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
5006 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00005007
Georg Brandl3ee81df2008-05-17 18:14:43 +00005008- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00005014- Issue #1631171: Re-implement the 'warnings' module in C (the
5015 original Python code has been kept as backup). This will allow for
5016 using the 'warning's machinery in such places as the parser where
5017 use of pure Python code is not possible. Both the ``showarning()``
5018 and ``formatwarning()`` gain an optional 'line' argument which is
5019 not called by default for backwards-compatibility reasons. Setting
5020 ``warnings.showwarning()`` to an implementation that lacks support
5021 for the ``line`` argument will raise a DeprecationWarning.

5045
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005046- The getpass module has been improved on Unix. It now uses /dev/tty
5047 by default and uses stderr instead of stdout. A GetPassWarning is
5048 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00005049

Georg Brandl3ee81df2008-05-17 18:14:43 +00005063- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005064 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005084- Issue #2550: The approach used by client/server code for obtaining
5085 ports to listen on in network-oriented tests has been refined in an
5086 effort to facilitate running multiple instances of the entire
5087 regression test suite in parallel without issue.
5088 test_support.bind_port() has been fixed such that it will always
5089 return a unique port -- which wasn't always the case with the
5090 previous implementation, especially if socket options had been set
5091 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5092 new implementation of bind_port() will actually raise an exception
5093 if it is passed an AF_INET/SOCK_STREAM socket with either the
5094 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5095 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5096 the socket it's been passed. This currently only applies to
5097 Windows. This option prevents any other sockets from binding to the
5098 host/port we've bound to, thus removing the possibility of the
5099 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5100 when a second SOCK_STREAM socket binds and accepts to a host/port
5101 that's already been bound by another socket. The optional preferred
5102 port parameter to bind_port() has been removed. Under no
5103 circumstances should tests be hard coding ports!
5104
5105 test_support.find_unused_port() has also been introduced, which will
5106 pass a temporary socket object to bind_port() in order to obtain an
5107 unused port. The temporary socket object is then closed and
5108 deleted, and the port is returned. This method should only be used
5109 for obtaining an unused port in order to pass to an external program
5110 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5111 a parameter to a server-oriented class that doesn't give you direct
5112 access to the underlying socket used.
5113
5114 Finally, test_support.HOST has been introduced, which should be used
5115 for the host argument of any relevant socket calls (i.e. bind and
5116 connect).

Fred Drakea8ee94b2008-03-01 02:45:07 +00005393- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005394 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005395
Georg Brandlad61bc82008-02-23 15:11:18 +00005396- Issue #2067: file.__exit__() now calls subclasses' close() method.
5397
5398- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005399
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005400- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005401 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005402
Eric Smitha73fbe72008-02-23 03:09:44 +00005403- Added the future_builtins module, which contains hex() and oct().
5404 These are the PEP 3127 version of these functions, designed to be
5405 compatible with the hex() and oct() builtins from Python 3.0. They
5406 differ slightly in their output formats from the existing, unchanged
5407 Python 2.6 builtins. The expected usage of the future_builtins
5408 module is:
5409 from future_builtins import hex, oct
5410
Eric Smith7ef40bf2008-02-20 23:34:22 +00005411- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5412 exponents for exponents with absolute value < 100. Follows C99
5413 standard. This is a change on Windows, which would use 3 digits.
5414 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5415 so that any alterations it does to the resulting string will be
5416 available in stringlib/formatter.h (for float.__format__).
5417
Eric Smith5a3c1352008-02-19 13:21:56 +00005418- Implemented PEP 3101, Advanced String Formatting. This adds a new
5419 builtin format(); a format() method for str and unicode; a
5420 __format__() method to object, str, unicode, int, long, float, and
5421 datetime; the class string.Formatter; and the C API
5422 PyObject_Format().
5423
Georg Brandl3ee81df2008-05-17 18:14:43 +00005424- Fixed several potential crashes, all caused by specially crafted
5425 __del__ methods exploiting objects in temporarily inconsistent
5426 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005427
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005428- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005429 prevent a possible crash: an Abstract Base Class would try to access
5430 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005431
Georg Brandl3ee81df2008-05-17 18:14:43 +00005432- Fixed repr() and str() of complex numbers with infinity or nan as
5433 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005434
Georg Brandl3ee81df2008-05-17 18:14:43 +00005435- Clear all free lists during a gc.collect() of the highest generation
5436 in order to allow pymalloc to free more arenas. Python may give back
5437 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005438
Georg Brandl3ee81df2008-05-17 18:14:43 +00005439- Issue #2045: Fix an infinite recursion triggered when printing a
5440 subclass of collections.defaultdict, if its default_factory is set
5441 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005442
Christian Heimesf75dbef2008-02-08 00:11:31 +00005443- Fixed a minor memory leak in dictobject.c. The content of the free
5444 list was not freed on interpreter shutdown.
5445
Georg Brandl21e99f42010-03-07 15:23:59 +00005446- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005447 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005448
Georg Brandl3ee81df2008-05-17 18:14:43 +00005449- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5450 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005451 to compact the internal free lists of pre-allocted ints and floats.
5452
Georg Brandl3ee81df2008-05-17 18:14:43 +00005453- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5454 calls. Python expected the return type int but the fork familie
5455 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005456
Georg Brandl3ee81df2008-05-17 18:14:43 +00005457- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5458 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005459
Georg Brandl3ee81df2008-05-17 18:14:43 +00005460- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5461 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005462
Georg Brandl3ee81df2008-05-17 18:14:43 +00005463- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5464 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005465
Georg Brandl3ee81df2008-05-17 18:14:43 +00005466- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5467 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005468
Georg Brandl3ee81df2008-05-17 18:14:43 +00005469- Patch #1473257: generator objects gain a gi_code attribute. This is
5470 the same object as the func_code attribute of the function that
5471 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005472
Georg Brandl3ee81df2008-05-17 18:14:43 +00005473- Issue #1920: "while 0" statements were completely removed by the
5474 compiler, even in the presence of an "else" clause, which is
5475 supposed to be run when the condition is false. Now the compiler
5476 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005477
Guido van Rossumeead05f2008-01-24 18:21:02 +00005478- A few crashers fixed: weakref_in_del.py (issue #1377858);
5479 loosing_dict_ref.py (issue #1303614, test67.py);
5480 borrowed_ref_[34].py (not in tracker).
5481
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005482- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005483 suppressed while an extension is loaded by calling SetErrorMode in
5484 dynload_win.c. The error is still reported properly.
5485
Georg Brandl3ee81df2008-05-17 18:14:43 +00005486- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005487 several extension methods and modules do not work without unicode
5488 support.
5489
Georg Brandl26543b12008-01-21 18:36:51 +00005490- Issue #1882: when compiling code from a string, encoding cookies in the
5491 second line of code were not always recognized correctly.
5492
Georg Brandl14404b62008-01-19 19:27:05 +00005493- Issue #1679: "0x" was taken as a valid integer literal.
5494
Georg Brandl6caad7d2008-01-26 14:19:22 +00005495- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005496 added.
5497
Christian Heimesc94e2b52008-01-14 04:13:37 +00005498- sys.float_info / PyFloat_GetInfo: The floating point information
5499 object was converted from a dict to a specialized structseq object.
5500
Georg Brandl3ee81df2008-05-17 18:14:43 +00005501- Patch #1816: Added sys.flags structseq. It exposes the status of
5502 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005503
Georg Brandl3ee81df2008-05-17 18:14:43 +00005504- Objects/structseq.c: Implemented new structseq representation. The
5505 patch makes structseqs (e.g. the return value of os.stat) more
5506 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005507
Georg Brandl3ee81df2008-05-17 18:14:43 +00005508- Patch #1700288: added a type attribute cache that caches method
5509 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005510
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005511- Bug #1776: __import__() no longer accepts filenames on any platform.
5512 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005513

5515
Georg Brandl3ee81df2008-05-17 18:14:43 +00005516- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5517 envvar and sys.dont_write_bytecode attribute. All these can be set
5518 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005519
Georg Brandl3ee81df2008-05-17 18:14:43 +00005520- Improve some exception messages when Windows fails to load an
5521 extension module. Now we get for example '%1 is not a valid Win32
5522 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005523
Georg Brandl3ee81df2008-05-17 18:14:43 +00005524- Bug #1481296: Fixed long(float('nan')) != 0L.

5527 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005528
Christian Heimes0a8143f2007-12-18 23:22:54 +00005529- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005530 and INF. float("nan"), float("inf") and float("-inf") now work on
5531 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005532
Georg Brandl3ee81df2008-05-17 18:14:43 +00005533- Compiler now generates simpler and faster code for dictionary
5534 literals. The oparg for BUILD_MAP now indicates an estimated
5535 dictionary size. There is a new opcode, STORE_MAP, for adding
5536 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005570- Issue #1265: Fix a problem with sys.settrace, if the tracing
5571 function uses a generator expression when at the same time the
5572 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005573
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005574- sets and frozensets now have an isdisjoint() method.

Georg Brandl21e99f42010-03-07 15:23:59 +00005580- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005581 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5582 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005583
Georg Brandl3ee81df2008-05-17 18:14:43 +00005584- Issue #1686386: Tuple's tp_repr did not take into account the
5585 possibility of having a self-referential tuple, which is possible
5586 from C code. Nor did object's tp_str consider that a type's tp_str
5587 could do something that could lead to an inifinite recursion.
5588 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5589 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005590
Georg Brandl3ee81df2008-05-17 18:14:43 +00005591- Issue #1164: It was possible to trigger deadlock when using the

5593 as needed. Now PyObject_Print() does the right thing along with
5594 various tp_print implementations of the built-in types and those in
5595 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005597- Issue #1147: Exceptions were directly allowing string exceptions in
5598 their throw() method even though string exceptions no longer
5599 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005601- Issue #1096: Prevent a segfault from getting the repr of a very
5602 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005603
Brett Cannon1e534b52007-09-07 04:18:30 +00005604- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005605 PyObject_Call() never calling back out to Python code to trigger
5606 recursion depth updates/checks. Required the creation of a static
5607 RuntimeError instance in case normalizing an exception put the
5608 recursion check value past its limit. Fixes crashers
5609 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005624- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005625 __*__ attributes. (Some already existed, e.g., __doc__ and
5626 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005627
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005628- Add -3 option to the interpreter to warn about features that are

5632 calls.
5633
Collin Winter62903052007-05-18 23:11:24 +00005634- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005635 "except E as target:". This is to provide forwards compatibility
5636 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005637
Brett Cannon229cee22007-05-05 01:34:02 +00005638- Deprecate BaseException.message as per PEP 352.
5639
Georg Brandl3ee81df2008-05-17 18:14:43 +00005640- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00005643- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005644 setting a plain string, ie don't expand to single letter identifiers.
5645
Raymond Hettinger13936692007-04-11 18:40:58 +00005646- Request #1191699: Slices can now be pickled.
5647
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005648- Request #1193128: str.translate() now allows a None argument for
5649 translations that only remove characters without re-mapping the
5650 remaining characters.
5651
Georg Brandl5cb76c12007-03-21 09:00:39 +00005652- Patch #1682205: a TypeError while unpacking an iterable is no longer

5654
Neal Norwitzaa754b72007-03-21 06:39:48 +00005655- Remove unused file Python/fmod.c.
5656
Guido van Rossum143b5642007-03-23 04:58:42 +00005657- Bug #1683368: The object.__init__() and object.__new__() methods are
5658 now stricter in rejecting excess arguments. The only time when
5659 either allows excess arguments is when it is not overridden and the
5660 other one is. For backwards compatibility, when both are
5661 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005662 warning later). Also, type.__init__() insists on the same signature
5663 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005664
Georg Brandl3ee81df2008-05-17 18:14:43 +00005665- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5666 object to complex using its __complex__() method before falling back
5667 to the __float__() method. Therefore, the functions in the cmath
5668 module now can operate on objects that define a __complex__()
5669 method.

5686
Georg Brandl7b9c5552007-03-12 14:30:05 +00005687- Bug #1678647: write a newline after printing an exception in any
5688 case, even when converting the value to a string failed.
5689
Georg Brandl871f1bc2007-03-12 13:17:36 +00005690- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005691 its argument, if it exists. If not, it will work like before. This
5692 allows customizing the output of dir() in the presence of a
5693 __getattr__().

5702 parthensized forms. This means complex(repr(x)) now works instead of
5703 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005704
Georg Brandlaa2321b2007-03-07 00:40:28 +00005705- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005706 makes the filenames the warning module prints much more sensible
5707 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005708

Georg Brandl0fca97a2007-03-05 22:28:08 +00005720- Patch #1674228: when assigning a slice (old-style), check for the
5721 sq_ass_slice instead of the sq_slice slot.
5722
Georg Brandl3ee81df2008-05-17 18:14:43 +00005723- When printing an unraisable error, don't print exceptions. before

6334 Python would crash instead of raising an error.
6335

6351 accepted in TestSuite.addTest(). This should cause no
6352 incompatibility since it never made sense with ordinary subclasses
6353 -- the failure just occurred later, with a more cumbersome
6354 exception.

6637 obtained from the TLS negotiation itself. Patch contributed by Bill
6638 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006639
Georg Brandl3ee81df2008-05-17 18:14:43 +00006640- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006641 that the SMTP.starttls() caller no longer needs to call ehlo()
6642 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006643 does not claim to support starttls. Adds the
6644 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6725 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6726 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006743 time so that opening a database previously created with the DB_DUP
6744 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6745 opens. Specifically: dictionary assignment to a DB object will
6746 replace all values for a given key when the database allows
6747 duplicate values. DB users should use DB.put(k, v) when they want
6748 to store duplicates; not DB[k] = v.

6755 characters with ASCII value less than 32. Also, it correctly quotes
6756 dots only if they occur on a single line, as opposed to the previous
6757 behavior of quoting dots if they are the second character of any
6758 line.

7081-----
7082
Georg Brandl3ee81df2008-05-17 18:14:43 +00007083- Unified naming convention for free lists and their limits. All free
7084 lists in Object/ are named ``free_list``, the counter ``numfree``
7085 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7086 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007087
Georg Brandl3ee81df2008-05-17 18:14:43 +00007088- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7089 to ``PyTuple_SetItem``, it can be used to populate a brand new
7090 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007091
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007092- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007094- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7095 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7096 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007097
7098- Patch #1720595: add T_BOOL to the range of structmember types.
7099
7100- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7101 ``PyFloat_GetInfo()`` to the float API.
7102
Georg Brandl3ee81df2008-05-17 18:14:43 +00007103- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7104 of w# format code incorrectly truncated the length to an int, even
7105 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7106 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007107
Georg Brandl3ee81df2008-05-17 18:14:43 +00007108- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7109 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007110
Georg Brandl3ee81df2008-05-17 18:14:43 +00007111- PEP 3123: Provide forward compatibility with Python 3.0, while
7112 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7113 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007114
Georg Brandl3ee81df2008-05-17 18:14:43 +00007115- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7116 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007117
7118- Patch #1733960: Allow T_LONGLONG to accept ints.
7119
7120- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7121

7125
7126- Fix some leftovers from the conversion from int to Py_ssize_t
7127 (relevant to strings and sequences of more than 2**31 items).
7128
7129- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7130 outside of pystate.c and should not be necessary.
7131
Georg Brandl3ee81df2008-05-17 18:14:43 +00007132- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7133 absolute imports. In earlier versions they might have used relative
7134 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007135
Georg Brandl3ee81df2008-05-17 18:14:43 +00007136- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7137 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007138
Georg Brandl3ee81df2008-05-17 18:14:43 +00007139- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7140 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007146- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7147 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7148 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7149 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007150
Georg Brandl3ee81df2008-05-17 18:14:43 +00007151- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00007164- Removed the macfs module. It had been deprecated since Python 2.5.
7165 This lead to the deprecation of macostools.touched() as it relied
7166 solely on macfs and was a no-op under OS X.
