Ned Deily18fae3f2013-01-31 01:24:55 -0800905- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
906 In particular, fix extension module build failures when trying to use
907 32-bit-only installer Pythons on systems with Xcode 4 (currently
908 OS X 10.8, 10.7, and optionally 10.6).
909 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
910 * Since Xcode 4 removes ppc support, extension module builds now
911 check for ppc compiler support and by default remove ppc and
912 ppc64 archs when they are not available.
913 * Extension module builds now revert to using system installed
914 headers and libs (/usr and /System/Library) if the SDK used
915 to build the interpreter is not installed or has moved.
916 * Try to avoid building extension modules with deprecated
917 and problematic Apple llvm-gcc compiler. If original compiler
918 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001204- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1205 int.__pow__. These overflow checks were causing int.__pow__ to produce
1206 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001207 compiler optimizing the check away. Also fix similar overflow checks
1208 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1209 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01001277- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001278 has left two versions of customize_compiler, the original in
1279 distutils.sysconfig and another copy in distutils.ccompiler, with some

1282 is the case in 3.x.
1283
Ned Deily0d0ea482012-02-10 12:59:06 +01001284- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1285 Distutils-based packages with C extension modules may fail because
1286 Apple has removed gcc-4.2, the version used to build python.org
1287 64-bit/32-bit Pythons. If the user does not explicitly override
1288 the default C compiler by setting the CC environment variable,
1289 Distutils will now attempt to compile extension modules with clang
1290 if gcc-4.2 is required but not found. Also as a convenience, if
1291 the user does explicitly set CC, substitute its value as the default
1292 compiler in the Distutils LDSHARED configuration variable for OS X.
1293 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1294 SDK, neither of which are available in Xcode 4. This change does not
1295 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001568- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1569 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1570 interpreter process. This could cause failures in non-Distutils subprocesses
1571 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001572 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001573 deployment target only in the environment of each build subprocess. It is
1574 still possible to globally override the default by setting
1575 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1576 greater or equal to the default value, the value with which the interpreter
1577 was built.

1604
Barry Warsawc5643282011-07-19 17:06:30 -04001605- sys.setcheckinterval() now updates the current ticker count as well as
1606 updating the check interval, so if the user decreases the check interval,
1607 the ticker doesn't have to wind down to zero from the old starting point
1608 before the new interval takes effect. And if the user increases the
1609 interval, it makes sure the new limit takes effect right away rather have an
1610 early task switch before recognizing the new interval.

2562 This prevents user-created self-referencing ordered dictionaries from
2563 becoming permanently uncollectable GC garbage. The downside is that
2564 removing __del__ means that the internal doubly-linked list has to wait for
2565 GC collection rather than freeing memory immediately when the refcnt drops
2566 to zero.

2575 original error is re-raised.

2596
R. David Murray7c4bf552010-08-25 01:45:57 +00002597- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

3024
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003025- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3026 start byte and the continuation byte(s) are now considered invalid, instead
3027 of the number of bytes specified by the start byte.
3028 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3029 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3030 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003039- Issue #8748: Fix two issues with comparisons between complex and integer
3040 objects. (1) The comparison could incorrectly return True in some cases
3041 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3042 (2) The comparison raised an OverflowError for large integers, leading
3043 to unpredictable exceptions when combining integers and complex objects
3044 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003046- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00003183- Issue #1533: Fix inconsistency in range function argument processing: any
3184 non-float non-integer argument is now converted to an integer (if possible)
3185 using its __int__ method. Previously, only small arguments were treated this
3186 way; larger arguments (those whose __int__ was outside the range of a C long)
3187 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00003195 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00003196 benefit compared to the dynamic memory allocation fallback. Patch by

3222 messages when accessing undefined class attributes because of the cheap
3223 inheritance with the underlying socket object. The cheap inheritance has been
3224 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00003225

Georg Brandlfee0f442010-05-22 21:26:21 +00003237- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3238 operation raises multiple signals and more than one of those signals is
3239 trapped, the specification determines the order in which the signals should be
3240 handled. In many cases this order wasn't being followed, leading to the wrong
3241 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00003242

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003411- Issue #7301: Add environment variable $PYTHONWARNINGS.
3412
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003413- Issue #8329: Don't return the same lists from select.select when no fds are
3414 changed.
3415
Georg Brandlfee0f442010-05-22 21:26:21 +00003416- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003417 on 64-bit machines. The shift count for either left or right shift is
3418 permitted to be up to sys.maxsize.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003424- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3425
Georg Brandlfee0f442010-05-22 21:26:21 +00003426- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3427 with a non-empty format string. This is an effort to future-proof user
3428 code. If a derived class does not currently implement __format__ but later
3429 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003430 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003431 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003432
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003433- Issue #8268: Old-style classes (not just instances) now support weak
3434 references.
3435
Georg Brandlfee0f442010-05-22 21:26:21 +00003436- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
3437 is set.

3445
Victor Stinner66644262010-03-10 22:30:19 +00003446- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003447 (SIGINT). If an error occurs while importing the site module, the error is
3448 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003449 module.

3463
Georg Brandlfee0f442010-05-22 21:26:21 +00003464- Issue #8257: The Decimal construct now accepts a float instance directly,
3465 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003466
3467 >>> Decimal(1.1)
3468 Decimal('1.100000000000000088817841970012523233890533447265625')
3469
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003470- collections.Counter() now supports a subtract() method.
3471
Georg Brandlfee0f442010-05-22 21:26:21 +00003472- The functools module now has a total_ordering() class decorator to simplify
3473 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003474
Georg Brandlfee0f442010-05-22 21:26:21 +00003475- The functools module also adds cmp_to_key() as a tool to transition old-style
3476 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003477
Georg Brandlfee0f442010-05-22 21:26:21 +00003478- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3479 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003480
Georg Brandlfee0f442010-05-22 21:26:21 +00003481- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3482 InvalidOperation instead of returning False. (Comparisons involving a quiet
3483 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3484 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003485
Georg Brandlfee0f442010-05-22 21:26:21 +00003486- Issue #2531: Comparison operations between floats and Decimal instances now
3487 return a result based on the numeric values of the operands; previously they
3488 returned an arbitrary result based on the relative ordering of id(float) and
3489 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003490
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003491- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003492 argument `-` which tells it to read files to compile from stdin. Each line is
3493 read on demand and the named file is compiled immediately. (Original patch by
3494 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003495
Georg Brandlfee0f442010-05-22 21:26:21 +00003496- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3497 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003499- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3500 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003501 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003502
Georg Brandlfee0f442010-05-22 21:26:21 +00003503- Comparisons using one of <, <=, >, >= between a complex instance and a
3504 Fractions instance now raise TypeError instead of returning True/False. This
3505 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3506 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003507

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003517- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003518 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3519 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003520
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003521- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3522 deprecated.
3523
Georg Brandlfee0f442010-05-22 21:26:21 +00003524- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3525 is running in WOW64 mode on 64 bit Windows.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003561- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003562 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3563 log file to compute the next rollover time. If the log file does not exist,
3564 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +00003574- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3575 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3576 This is a behavior change, so email's minor version number is now bumped, to
3577 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003605- Issue #8300: When passing a non-integer argument to struct.pack with any
3606 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003610- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3611 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3612 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003613 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3614 inconsistent: __int__ was used for some integer codes but not for others, and
3615 the set of integer codes for which it was used differed between native packing
3616 and standard packing.)

4020Core and Builtins
4021-----------------
4022
Georg Brandlba83f822010-03-14 09:50:54 +00004023- The ``__complex__()`` method is now looked up on the class of instances to
4024 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004026- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

4028
Mark Dickinson1b34d252010-01-01 17:27:30 +00004029- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004030 DeprecationWarning when passed a float argument where an integer was expected.
4031 These functions and methods now raise TypeError instead. The majority of the
4032 effects of this change are in the extension modules, but some core functions
4033 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4034 and many unicode/str methods.

4045 used to drop the time part of the result.
4046
Georg Brandlba83f822010-03-14 09:50:54 +00004047- Issue #1811: Improve accuracy and cross-platform consistency for true division
4048 of integers: the result of a/b is now correctly rounded for ints a and b (at
4049 least on IEEE 754 platforms), and in particular does not depend on the
4050 internal representation of a long.

4058
Georg Brandlba83f822010-03-14 09:50:54 +00004059 These executables now work properly with the arch(1) command: ``arch -ppc
4060 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004217- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4218 decimal string that's guaranteed to round back to x under correct rounding
4219 (with round-half-to-even rounding mode). Previously it gave a string based on
4220 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4221 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4222 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004223
Georg Brandlba83f822010-03-14 09:50:54 +00004224- Issue #7117: On almost all platforms: float-to-string and string-to-float
4225 conversions within Python are now correctly rounded. Places these conversions
4226 occur include: str for floats and complex numbers; the float and complex
4227 constructors; old-style and new-style numeric formatting; serialization and
4228 deserialization of floats and complex numbers using marshal, pickle and json;
4229 parsing of float and imaginary literals in Python code; Decimal-to-float
4230 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004231
Georg Brandlba83f822010-03-14 09:50:54 +00004232 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4233 providing correctly-rounded strtod and dtoa C functions. This code is
4234 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4235 the C compiler. There may be a small number of platforms on which correct
4236 operation of this code cannot be guaranteed, so the code is not used: notably,
4237 this applies to platforms where the C double format is not IEEE 754 binary64,
4238 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4239 and Python's configure script is unable to determine how to change the FPU
4240 precision. On these platforms conversions use the platform strtod and dtoa,
4241 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004243- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4244 uses the correctly-rounded string <-> float conversions described above (when
4245 available), and so produces correctly rounded results that will display nicely
4246 under the float repr. There are two related small changes: (1) round now
4247 accepts any class with an ``__index__()`` method for its second argument (but
4248 no longer accepts floats for the second argument), and (2) an excessively
4249 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4250 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004392
Georg Brandlba83f822010-03-14 09:50:54 +00004393 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4394 (2) parsing of strings representing infinities and nans was locale aware; and
4395 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00004396
Georg Brandlba83f822010-03-14 09:50:54 +00004397- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4398 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4399 but with at least one decimal point and with a default precision
4400 of 12. Previously, the behavior the same but with a default precision of 6.
4401 This more closely matches ``str()``, and reduces surprises when adding
4402 alignment flags to the empty presentation type. This also affects the new
4403 complex.__format__ in the same way.
4404
4405- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4406 classtype's, even if it was None. property now inserts the __doc__ into the
4407 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00004468 untrackable objects are not tracked by the garbage collector. This can reduce

4477 internal representation of integers, for performance reasons. Base 2**30 is
4478 enabled by default on 64-bit machines. Add --enable-big-digits option to
4479 configure, which overrides the default. Add sys.long_info structseq to
4480 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004581- Issue #4597: Fixed exception handling when the __exit__ function of a context
4582 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00004583
Georg Brandlba83f822010-03-14 09:50:54 +00004584- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00004585
Georg Brandlba83f822010-03-14 09:50:54 +00004586- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4587 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4588 instances. On a typical machine this saves 3 bytes of memory (on average) per
4589 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004590
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004591- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4592 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4593 instead of throwing a MemoryError.
4594
Georg Brandlba83f822010-03-14 09:50:54 +00004595- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4596 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004597
Benjamin Petersonc078f922008-11-21 22:27:24 +00004598- Issue #4367: Python would segfault during compiling when the unicodedata
4599 module couldn't be imported and \N escapes were present.
4600
Georg Brandlba83f822010-03-14 09:50:54 +00004601- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4602 file objects with closefd=False. The file descriptor is still kept open but
4603 the file object behaves like a closed file. The ``FileIO`` object also got a
4604 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004605
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004606- Issue #4348: Some bytearray methods returned that didn't cause any change to
4607 the bytearray, returned the same bytearray instead of a copy.
4608
Georg Brandlba83f822010-03-14 09:50:54 +00004609- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00004610
Benjamin Peterson273c2332008-11-17 22:39:09 +00004611- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
4612
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004613- Issue #4048: The parser module now correctly validates relative imports.
4614
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004615- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
4616 exec statement.
4617
Georg Brandlba83f822010-03-14 09:50:54 +00004618- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4619 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00004620
Benjamin Petersonbdca9422008-10-26 20:21:13 +00004621- Issue #4209: Enabling unicode_literals and the print_function in the same
4622 __future__ import didn't work.
4623
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004624- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004625 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004626
Georg Brandlba83f822010-03-14 09:50:54 +00004627- On windows, ``os.chdir()`` given unicode was not working if
4628 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4629 this code path is really executed because I cannot move to such directory on
4630 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004631
Georg Brandlba83f822010-03-14 09:50:54 +00004632- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4633 element is temporarily replaced with an equivalent frozenset. But the
4634 eventual KeyError would always report the empty ``frozenset()`` as the missing
4635 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004636
Georg Brandlba83f822010-03-14 09:50:54 +00004637- Issue #4509: Various issues surrounding resize of bytearray objects to which
4638 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00004639
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00004640- Issue #4748: Lambda generators no longer return a value.
4641
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00004642- Issue #3582: Use native TLS functions on Windows
4643
Gregory P. Smithae91d092009-03-02 05:13:57 +00004644- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
4645
Georg Brandlba83f822010-03-14 09:50:54 +00004646- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
4647 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00004648
Matthias Klose91a3b9e2009-04-05 21:19:13 +00004649- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
4650 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00004651
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004652- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4653 returned them on 64bit platforms.
4654
Walter Dörwalded960ac2009-05-03 22:36:33 +00004655- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4656 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4657 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4658 of using the replace error handler in PyUnicode_DecodeUTF8().
4659
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004660- Issue #3739: The unicode-internal encoder now reports the number of characters
4661 consumed like any other encoder (instead of the number of bytes).
4662
Georg Brandlba83f822010-03-14 09:50:54 +00004663- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4664 allocator will be automatically disabled when running under Valgrind. This
4665 gives improved memory leak detection when running under Valgrind, while taking
4666 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00004691- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
4692 ownership when the group is not forced, because the group may be different
4693 from the user's group and inherit from its container when the test is run.

Georg Brandlba83f822010-03-14 09:50:54 +00004735- Issue #6816: runpy now provides a run_path function that allows Python code to
4736 execute file paths that refer to source or compiled Python files as well as
4737 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00004738 __main__.py file. This allows applications that run other Python scripts to
4739 support the same flexibility as the CPython command line itself.
4740
Georg Brandlba83f822010-03-14 09:50:54 +00004741- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
4742 connection with another process, rather than looping endlessly. The default
4743 timeout is 20 seconds, which should be amply sufficient for local connections.

5833 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5834 neither __int__ nor __long__, TypeError used to be raised (with a

6032
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006033- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6034 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6035 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6036 ``printf`` function, whereas PyString_FromFormat has an independent
6037 implementation and uses "%zd" on all platforms for size_t values.
6038 This makes a difference on win64, where ``printf`` needs "%Id" to display
6039 64bit values.

6045 object; previously an int would be returned for small values. the __long__
6046 method is allowed to return either an int or a long, but the behaviour of
6047 float objects should not change to respect backward compatibility.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006055 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006056 was correctly parsed but parsing of subsequent arguments failed.
6057
Vinay Sajip35e3b032008-09-01 14:33:59 +00006058- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006059 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6060 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6061 when given a tuple of classes as second argument, were looking up
6062 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6063 type object.
6064
Neal Norwitz18aa3882008-08-24 05:04:52 +00006065- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006134 warnings.catch_warnings() along with some API cleanup. Expanding the tests

6208-----------------
6209
Guido van Rossumf8402962008-08-20 15:01:50 +00006210- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6211 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6212 extensions do not automatically benefit from the class attribute
6213 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6214 to their tp_flags field if they care. This is a backwards
6215 compatibility feature; in 3.0, all types will use the cache by
6216 default.
6217
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006218- Keyword arguments can now follow starred arguments. (``f(a, *args,
6219 keyword=23)`` is now valid syntax.)
6220
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006221- ctypes function pointers that are COM methods have a boolean True
6222 value again.

6233
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006234- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6235 (64bit Unix, for example), unichr() would truncate its argument and return
6236 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006240- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6241 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6242
Antoine Pitrou92f82162008-07-25 22:22:08 +00006243- Issue #1819: function calls with several named parameters are now on
6244 average 35% faster (as measured by pybench).
6245
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006246- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6247 the python debugger steps into a class statement: the free variables (local
6248 variables defined in an outer scope) would be deleted from the outer scope.
6249
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006250- Issue #2620: Overflow checking when allocating or reallocating memory
6251 was not always being done properly in some python types and extension
6252 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6253 all been updated to perform better checks and places in the code that
6254 would previously leak memory on the error path when such an allocation
6255 failed have been fixed.

6261
Benjamin Petersone977ad42008-08-20 01:42:01 +00006262- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6263 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6264
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006265- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6266 version reported by these tools does not necessarily follow the python
6267 version numbering scheme, so the module is less strict when parsing it.
6268
Nick Coghlanf70385a2008-08-18 12:42:46 +00006269- Issue #2235: Added Py3k warnings for types which will become unhashable
6270 under the stricter __hash__ inheritance rules in 3.0. Several types
6271 which did not meet the rules for hash invariants and were already
6272 unhashable in 3.0 have now been explicitly flagged as unhashable in
6273 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6274 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6275
Brett Cannon88f801d2008-08-18 00:46:22 +00006276- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6277 imported into the module but exposed as part of the module's API.
6278

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006285- Issue #3575: Incremental decoder's decode function now takes bytearray
6286 by using 's*' instead of 't#'.
6287
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006288- Issue #2222: Fixed reference leak when occurred os.rename()

6298 after a 302 response in the case of not going through a proxy.
6299
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006300- Issue #2676: in the email package, content-type parsing was hanging on
6301 pathological input because of quadratic or exponential behaviour of a
6302 regular expression.
6303
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006304- Issue #3476: binary buffered reading through the new "io" library is now
6305 thread-safe.
6306
Brett Cannonbf3157b2008-08-14 05:00:03 +00006307- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6308 since mimetools itself is deprecated. Because modules are cached, all
6309 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6310
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006311- Issue #3134: shutil referenced undefined WindowsError symbol.

6314 menu entries were not deleted.
6315
Brett Cannon83e81842008-08-09 23:30:55 +00006316- Copied the implementation of reduce() to _functools.reduce() to have a

6318
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006319- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6320 a MemoryError rather than silently stop the iteration.
6321
Guido van Rossum59ce9012008-08-09 14:55:34 +00006322- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6323 to _sre.compile() will now be rejected. This should not affect anybody
6324 since the re.compile() function never generates invalid re-bytecode.
6325
Skip Montanaroa032bf42008-08-08 22:52:51 +00006326- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6327 upon first access it can be automatically initialized from the csv file if
6328 it wasn't initialized during instantiation.
6329
Brett Cannon3aa2a492008-08-06 22:28:09 +00006330- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6331 the reload() built-in has been removed.
6332
Brett Cannon7e30b672008-08-04 21:52:25 +00006333- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006334 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6342 raised an AttributeError.
6343
Benjamin Peterson01a24322008-07-28 23:35:27 +00006344- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006345 asking for a specific length. This problem only affected files opened
6346 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006347

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006371- Issue #3394: zipfile.writestr sets external attributes when passed a
6372 file name rather than a ZipInfo instance, so files are extracted with
6373 mode 0600 rather than 000 under Unix.
6374
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006375- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6376 argument in python 2.5, this broke code that subclassed Popen to include its
6377 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006387- Issue #2235: the C API function PyObject_HashNotImplemented and its
6388 interaction with the tp_hash slot (added in 2.6b2) are now documented
6389
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006390- Issue #643841: The language reference now provides more detailed
6391 coverage of the lookup process for special methods. The disclaimers
6392 regarding lack of coverage of new-style classes have also been
6393 removed, since the coverage is now fairly reasonable.

6397================================
6398
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006399*Release date: 17-Jul-2008*
6400
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006401Core and Builtins
6402-----------------
6403
Georg Brandl3e483f62008-07-16 22:57:41 +00006404- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6405 its methods now allow for items objects that can be converted to
6406 an integer using operator.index().
6407
Mark Dickinson64b7e502008-07-16 09:40:03 +00006408- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6409 produced a ValueError instead of giving the correct float.
6410
Eric Smitha5fa5a22008-07-16 00:11:49 +00006411- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6412 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6413
Mark Dickinson7103aa42008-07-15 19:08:33 +00006414- Issue #3008: the float type has a new instance method 'float.hex'
6415 and a new class method 'float.fromhex' to convert floating-point
6416 numbers to and from hexadecimal strings, respectively.
6417
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006418- Issue #2235: __hash__ is once again inherited by default. To allow
6419 collections.Hashable to remain meaningful in the presence of the
6420 default hash implementation (object.__hash__), it is now possible
6421 to explicit block inheritance of hash by setting __hash__=None at
6422 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6423 level.
6424
Nick Coghlanb028f502008-07-13 14:52:36 +00006425- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6426 the parent module cannot be found while performing an absolute import.
6427 This means that an incorrectly defined __package__ attribute will
6428 now only prevent relative imports in that module rather than causing
6429 all imports from that module to fail.
6430
Nick Coghlan14ff9942008-07-08 14:21:42 +00006431- Issue #2517: Allow unicode messages in Exceptions again by correctly
6432 bypassing the instance dictionary when looking up __unicode__ on
6433 new-style classes.
6434
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006435- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6436 set to a custom object whose write() method happens to install
6437 another file in sys.stdout.
6438
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006439- Issue #3088: Corrected a race condition in classes derived from
6440 threading.local: the first member set by a thread could be saved in
6441 another thread's dictionary.
6442
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006443- Issue #3004: Minor change to slice.indices(): the start and stop
6444 arguments are now treated identically, making the behaviour easier
6445 to describe and understand. For example, slice(None, -10,
6446 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6447 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6448 10, -1).
6449
Georg Brandl278fc502008-07-19 12:46:12 +00006450- Issue #3219: Calling a function with repeated keyword arguments,
6451 f(a=2, a=23), would not cause a syntax error. This was a regression
6452 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006453
Georg Brandl278fc502008-07-19 12:46:12 +00006454- Issue #2862: Make int and float freelist management consistent with
6455 other freelists. Changes their CompactFreeList apis into
6456 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006457

6459-------
6460
Thomas Heller57adf222008-08-14 19:10:48 +00006461- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6462 api functions without holding the GIL, which could lead to a fatal
6463 error when they failed.
6464
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006465- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006473- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6474 ForkingPickler.register() to resolve conflict with ctypes.
6475
Vinay Sajip51e65192008-07-18 09:01:10 +00006476- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006477
Thomas Heller880f5292008-07-15 19:39:38 +00006478- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6479 a valid dlerror() message.
6480
Thomas Heller2bad6572008-07-15 17:19:50 +00006481- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6482 incomplete structure was created.
6483
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006484- Issue #3339: dummy_thread.acquire() should not return None.
6485
Raymond Hettingerb01713e2008-07-10 14:34:57 +00006486- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
6487
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006488- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006489
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006490- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6491 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006492 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006493 content-length. The problem had been corrected in the 2.4 branch, but never
6494 merged into trunk.
6495
Georg Brandle78fbcc2008-07-05 10:13:36 +00006496- Issue #2663: add filtering capability to shutil.copytree().

6502- Issue #1746: Correct handling of zipfile archive comments (previously
6503 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00006504 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006505
Vinay Sajip51e65192008-07-18 09:01:10 +00006506- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006507 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006508
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006509- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6510 handling is now the same as that of other special attributes like __name__).
6511
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006512- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6513 removal in Python 3.0 in favor of urllib2.urlopen().
6514
Gregory P. Smithf4140642008-07-06 07:16:40 +00006515- Issue #2113: Fix error in subprocess.Popen if the select system call is
6516 interrupted by a signal.

Georg Brandl5cc774e2008-06-11 20:28:06 +00006902 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006903
6904 This is controlled by the configure argument ``--with-universal-archs``:
6905
6906 - ``--with-universal-archs=all``: install 4-way universal
6907
6908 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6909
6910 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6911
6912 This option should be used in combination with ``--enable-universalsdk=``.
6913
6914 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006964- Issue #1631171: Re-implement the 'warnings' module in C (the
6965 original Python code has been kept as backup). This will allow for
6966 using the 'warning's machinery in such places as the parser where
6967 use of pure Python code is not possible. Both the ``showarning()``
6968 and ``formatwarning()`` gain an optional 'line' argument which is
6969 not called by default for backwards-compatibility reasons. Setting
6970 ``warnings.showwarning()`` to an implementation that lacks support
6971 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007034- Issue #2550: The approach used by client/server code for obtaining
7035 ports to listen on in network-oriented tests has been refined in an
7036 effort to facilitate running multiple instances of the entire
7037 regression test suite in parallel without issue.
7038 test_support.bind_port() has been fixed such that it will always
7039 return a unique port -- which wasn't always the case with the
7040 previous implementation, especially if socket options had been set
7041 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7042 new implementation of bind_port() will actually raise an exception
7043 if it is passed an AF_INET/SOCK_STREAM socket with either the
7044 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7045 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7046 the socket it's been passed. This currently only applies to
7047 Windows. This option prevents any other sockets from binding to the
7048 host/port we've bound to, thus removing the possibility of the
7049 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7050 when a second SOCK_STREAM socket binds and accepts to a host/port
7051 that's already been bound by another socket. The optional preferred
7052 port parameter to bind_port() has been removed. Under no
7053 circumstances should tests be hard coding ports!
7054
7055 test_support.find_unused_port() has also been introduced, which will
7056 pass a temporary socket object to bind_port() in order to obtain an
7057 unused port. The temporary socket object is then closed and
7058 deleted, and the port is returned. This method should only be used
7059 for obtaining an unused port in order to pass to an external program
7060 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7061 a parameter to a server-oriented class that doesn't give you direct
7062 access to the underlying socket used.
7063
7064 Finally, test_support.HOST has been introduced, which should be used
7065 for the host argument of any relevant socket calls (i.e. bind and
7066 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007067
7068 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007069 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

7071 test_asynchat and test_socket_ssl.
7072
Georg Brandl3ee81df2008-05-17 18:14:43 +00007073 It is now possible for multiple instances of the regression test
7074 suite to run in parallel without issue.

7341-----------------
7342
Fred Drakea8ee94b2008-03-01 02:45:07 +00007343- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007344 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007345
Georg Brandlad61bc82008-02-23 15:11:18 +00007346- Issue #2067: file.__exit__() now calls subclasses' close() method.
7347
7348- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007349
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007350- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007351 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007352
Eric Smitha73fbe72008-02-23 03:09:44 +00007353- Added the future_builtins module, which contains hex() and oct().
7354 These are the PEP 3127 version of these functions, designed to be
7355 compatible with the hex() and oct() builtins from Python 3.0. They
7356 differ slightly in their output formats from the existing, unchanged
7357 Python 2.6 builtins. The expected usage of the future_builtins
7358 module is:
7359 from future_builtins import hex, oct
7360
Eric Smith7ef40bf2008-02-20 23:34:22 +00007361- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7362 exponents for exponents with absolute value < 100. Follows C99
7363 standard. This is a change on Windows, which would use 3 digits.
7364 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7365 so that any alterations it does to the resulting string will be
7366 available in stringlib/formatter.h (for float.__format__).
7367
Eric Smith5a3c1352008-02-19 13:21:56 +00007368- Implemented PEP 3101, Advanced String Formatting. This adds a new
7369 builtin format(); a format() method for str and unicode; a
7370 __format__() method to object, str, unicode, int, long, float, and
7371 datetime; the class string.Formatter; and the C API
7372 PyObject_Format().
7373
Georg Brandl3ee81df2008-05-17 18:14:43 +00007374- Fixed several potential crashes, all caused by specially crafted
7375 __del__ methods exploiting objects in temporarily inconsistent
7376 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007377
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007378- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007379 prevent a possible crash: an Abstract Base Class would try to access
7380 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007381
Georg Brandl3ee81df2008-05-17 18:14:43 +00007382- Fixed repr() and str() of complex numbers with infinity or nan as
7383 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007384
Georg Brandl3ee81df2008-05-17 18:14:43 +00007385- Clear all free lists during a gc.collect() of the highest generation
7386 in order to allow pymalloc to free more arenas. Python may give back
7387 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007388
Georg Brandl3ee81df2008-05-17 18:14:43 +00007389- Issue #2045: Fix an infinite recursion triggered when printing a
7390 subclass of collections.defaultdict, if its default_factory is set
7391 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007392
Christian Heimesf75dbef2008-02-08 00:11:31 +00007393- Fixed a minor memory leak in dictobject.c. The content of the free
7394 list was not freed on interpreter shutdown.
7395
Georg Brandl21e99f42010-03-07 15:23:59 +00007396- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007397 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007398
Georg Brandl3ee81df2008-05-17 18:14:43 +00007399- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7400 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007401 to compact the internal free lists of pre-allocted ints and floats.
7402
Georg Brandl3ee81df2008-05-17 18:14:43 +00007403- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7404 calls. Python expected the return type int but the fork familie
7405 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007406
Georg Brandl3ee81df2008-05-17 18:14:43 +00007407- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7408 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007409
Georg Brandl3ee81df2008-05-17 18:14:43 +00007410- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7411 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007412
Georg Brandl3ee81df2008-05-17 18:14:43 +00007413- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7414 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007415
Georg Brandl3ee81df2008-05-17 18:14:43 +00007416- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7417 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007418
Georg Brandl3ee81df2008-05-17 18:14:43 +00007419- Patch #1473257: generator objects gain a gi_code attribute. This is
7420 the same object as the func_code attribute of the function that
7421 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007422
Georg Brandl3ee81df2008-05-17 18:14:43 +00007423- Issue #1920: "while 0" statements were completely removed by the
7424 compiler, even in the presence of an "else" clause, which is
7425 supposed to be run when the condition is false. Now the compiler
7426 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007427
Guido van Rossumeead05f2008-01-24 18:21:02 +00007428- A few crashers fixed: weakref_in_del.py (issue #1377858);
7429 loosing_dict_ref.py (issue #1303614, test67.py);
7430 borrowed_ref_[34].py (not in tracker).
7431
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007432- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007433 suppressed while an extension is loaded by calling SetErrorMode in
7434 dynload_win.c. The error is still reported properly.
7435
Georg Brandl3ee81df2008-05-17 18:14:43 +00007436- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007437 several extension methods and modules do not work without unicode
7438 support.
7439
Georg Brandl26543b12008-01-21 18:36:51 +00007440- Issue #1882: when compiling code from a string, encoding cookies in the
7441 second line of code were not always recognized correctly.
7442
Georg Brandl14404b62008-01-19 19:27:05 +00007443- Issue #1679: "0x" was taken as a valid integer literal.
7444
Georg Brandl6caad7d2008-01-26 14:19:22 +00007445- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007446 added.
7447
Christian Heimesc94e2b52008-01-14 04:13:37 +00007448- sys.float_info / PyFloat_GetInfo: The floating point information
7449 object was converted from a dict to a specialized structseq object.
7450
Georg Brandl3ee81df2008-05-17 18:14:43 +00007451- Patch #1816: Added sys.flags structseq. It exposes the status of
7452 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007453
Georg Brandl3ee81df2008-05-17 18:14:43 +00007454- Objects/structseq.c: Implemented new structseq representation. The
7455 patch makes structseqs (e.g. the return value of os.stat) more
7456 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007457
Georg Brandl3ee81df2008-05-17 18:14:43 +00007458- Patch #1700288: added a type attribute cache that caches method
7459 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007460
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007461- Bug #1776: __import__() no longer accepts filenames on any platform.
7462 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007463
Georg Brandlaed6c662008-01-07 17:25:53 +00007464- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7465
Georg Brandl3ee81df2008-05-17 18:14:43 +00007466- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7467 envvar and sys.dont_write_bytecode attribute. All these can be set
7468 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007469
Georg Brandl3ee81df2008-05-17 18:14:43 +00007470- Improve some exception messages when Windows fails to load an
7471 extension module. Now we get for example '%1 is not a valid Win32
7472 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007473
Georg Brandl3ee81df2008-05-17 18:14:43 +00007474- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007476- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7477 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007478
Christian Heimes0a8143f2007-12-18 23:22:54 +00007479- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007480 and INF. float("nan"), float("inf") and float("-inf") now work on
7481 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007482
Georg Brandl3ee81df2008-05-17 18:14:43 +00007483- Compiler now generates simpler and faster code for dictionary
7484 literals. The oparg for BUILD_MAP now indicates an estimated
7485 dictionary size. There is a new opcode, STORE_MAP, for adding
7486 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007487
Georg Brandl3ee81df2008-05-17 18:14:43 +00007488- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007493- Issue #1538: Avoid copying string in split/rsplit if the split char
7494 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007495
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007496- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007497 SystemError.
7498
Nick Coghlanef01d822007-12-03 12:55:17 +00007499- PEP 366: Allow explicit relative imports when executing modules

7501 __package__ attribute.
7502
Georg Brandl3ee81df2008-05-17 18:14:43 +00007503- Issue #1402: Fix a crash on exit, when another thread is still
7504 running, and if the deallocation of its frames somehow calls the
7505 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007506

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007510 attribute of an empty cell object.
7511
Georg Brandl3ee81df2008-05-17 18:14:43 +00007512- Issue #1460: The utf-7 incremental decoder did not accept truncated
7513 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007514
Georg Brandl3ee81df2008-05-17 18:14:43 +00007515- Patch #1739468: Directories and zipfiles containing a __main__.py
7516 file can now be directly executed by passing their name to the
7517 interpreter. The directory/zipfile is automatically inserted as the
7518 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007519
Georg Brandl3ee81df2008-05-17 18:14:43 +00007520- Issue #1265: Fix a problem with sys.settrace, if the tracing
7521 function uses a generator expression when at the same time the
7522 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007523
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007524- sets and frozensets now have an isdisjoint() method.
7525
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007526- optimize the performance of builtin.sum().
7527
Neal Norwitz44f326e2007-10-05 05:29:17 +00007528- Fix warnings found by the new version of the Coverity checker.
7529
Georg Brandl21e99f42010-03-07 15:23:59 +00007530- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007531 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7532 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007533
Georg Brandl3ee81df2008-05-17 18:14:43 +00007534- Issue #1686386: Tuple's tp_repr did not take into account the
7535 possibility of having a self-referential tuple, which is possible
7536 from C code. Nor did object's tp_str consider that a type's tp_str
7537 could do something that could lead to an inifinite recursion.
7538 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7539 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007540
Georg Brandl3ee81df2008-05-17 18:14:43 +00007541- Issue #1164: It was possible to trigger deadlock when using the
7542 'print' statement to write to a file since the GIL was not released
7543 as needed. Now PyObject_Print() does the right thing along with
7544 various tp_print implementations of the built-in types and those in
7545 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007546
Georg Brandl3ee81df2008-05-17 18:14:43 +00007547- Issue #1147: Exceptions were directly allowing string exceptions in
7548 their throw() method even though string exceptions no longer
7549 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007550

Brett Cannon1e534b52007-09-07 04:18:30 +00007554- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007555 PyObject_Call() never calling back out to Python code to trigger
7556 recursion depth updates/checks. Required the creation of a static
7557 RuntimeError instance in case normalizing an exception put the
7558 recursion check value past its limit. Fixes crashers
7559 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007560

Neal Norwitz0ac60192007-05-27 04:08:54 +00007574- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007575 __*__ attributes. (Some already existed, e.g., __doc__ and
7576 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007577
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007578- Add -3 option to the interpreter to warn about features that are

7582 calls.
7583
Collin Winter62903052007-05-18 23:11:24 +00007584- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007585 "except E as target:". This is to provide forwards compatibility
7586 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007587
Brett Cannon229cee22007-05-05 01:34:02 +00007588- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007593- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007594 setting a plain string, ie don't expand to single letter identifiers.
7595
Raymond Hettinger13936692007-04-11 18:40:58 +00007596- Request #1191699: Slices can now be pickled.

7601
Georg Brandl5cb76c12007-03-21 09:00:39 +00007602- Patch #1682205: a TypeError while unpacking an iterable is no longer

7606
Guido van Rossum143b5642007-03-23 04:58:42 +00007607- Bug #1683368: The object.__init__() and object.__new__() methods are
7608 now stricter in rejecting excess arguments. The only time when
7609 either allows excess arguments is when it is not overridden and the
7610 other one is. For backwards compatibility, when both are
7611 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007612 warning later). Also, type.__init__() insists on the same signature
7613 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007614
Georg Brandl3ee81df2008-05-17 18:14:43 +00007615- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7616 object to complex using its __complex__() method before falling back
7617 to the __float__() method. Therefore, the functions in the cmath
7618 module now can operate on objects that define a __complex__()
7619 method.

7636
Georg Brandl7b9c5552007-03-12 14:30:05 +00007637- Bug #1678647: write a newline after printing an exception in any
7638 case, even when converting the value to a string failed.
7639
Georg Brandl871f1bc2007-03-12 13:17:36 +00007640- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007641 its argument, if it exists. If not, it will work like before. This
7642 allows customizing the output of dir() in the presence of a
7643 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007644
Collin Winter276887b2007-03-12 16:11:39 +00007645- Patch #922167: Python no longer segfaults when faced with infinitely
7646 self-recursive reload() calls (as reported by bug #742342).

7652 parthensized forms. This means complex(repr(x)) now works instead of
7653 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007654
Georg Brandlaa2321b2007-03-07 00:40:28 +00007655- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007656 makes the filenames the warning module prints much more sensible
7657 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007658

Georg Brandl0fca97a2007-03-05 22:28:08 +00007670- Patch #1674228: when assigning a slice (old-style), check for the
7671 sq_ass_slice instead of the sq_slice slot.
7672
Georg Brandl3ee81df2008-05-17 18:14:43 +00007673- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00008208 AttributeError instead of an IOError when the server's response

8300 TestCase and TestSuite subclasses (not instances) are no longer

8583 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008584
Georg Brandl3ee81df2008-05-17 18:14:43 +00008585- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8586 with RFC 3207 and forgets any knowledge obtained from the server not
8587 obtained from the TLS negotiation itself. Patch contributed by Bill
8588 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008589
Georg Brandl3ee81df2008-05-17 18:14:43 +00008590- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008591 that the SMTP.starttls() caller no longer needs to call ehlo()
8592 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008593 does not claim to support starttls. Adds the
8594 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8675 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8676 silently miscode subclasses of those types. Now, it raises a
8677 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008678

Georg Brandl3ee81df2008-05-17 18:14:43 +00008693 time so that opening a database previously created with the DB_DUP
8694 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8695 opens. Specifically: dictionary assignment to a DB object will
8696 replace all values for a given key when the database allows
8697 duplicate values. DB users should use DB.put(k, v) when they want
8698 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008699

8705 characters with ASCII value less than 32. Also, it correctly quotes
8706 dots only if they occur on a single line, as opposed to the previous
8707 behavior of quoting dots if they are the second character of any
8708 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008709

Georg Brandl3ee81df2008-05-17 18:14:43 +00009038- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9039 to ``PyTuple_SetItem``, it can be used to populate a brand new
9040 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009044- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9045 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9046 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009047
9048- Patch #1720595: add T_BOOL to the range of structmember types.
9049
9050- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9051 ``PyFloat_GetInfo()`` to the float API.
9052
Georg Brandl3ee81df2008-05-17 18:14:43 +00009053- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9054 of w# format code incorrectly truncated the length to an int, even
9055 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9056 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009057
Georg Brandl3ee81df2008-05-17 18:14:43 +00009058- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9059 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009061- PEP 3123: Provide forward compatibility with Python 3.0, while
9062 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9063 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009064
Georg Brandl3ee81df2008-05-17 18:14:43 +00009065- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9066 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009067
9068- Patch #1733960: Allow T_LONGLONG to accept ints.
9069
9070- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9071
Christian Heimes000a0742008-01-03 22:16:32 +00009072- Added a new API function ``PyImport_ImportModuleNoBlock``.
9073
Georg Brandl6caad7d2008-01-26 14:19:22 +00009074- Bug #1637022: Prefix AST symbols with _Py_.
9075
9076- Fix some leftovers from the conversion from int to Py_ssize_t
9077 (relevant to strings and sequences of more than 2**31 items).
9078
9079- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9080 outside of pystate.c and should not be necessary.
9081
Georg Brandl3ee81df2008-05-17 18:14:43 +00009082- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9083 absolute imports. In earlier versions they might have used relative
9084 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009085
Georg Brandl3ee81df2008-05-17 18:14:43 +00009086- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9087 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009088
Georg Brandl3ee81df2008-05-17 18:14:43 +00009089- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
9090 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009096- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9097 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9098 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9099 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009100

Georg Brandl3ee81df2008-05-17 18:14:43 +00009114- Removed the macfs module. It had been deprecated since Python 2.5.
9115 This lead to the deprecation of macostools.touched() as it relied
9116 solely on macfs and was a no-op under OS X.
