David Malcolm4c29e1c2011-01-06 17:39:24 +0000301- Issue #10655: Fix the build on PowerPC on Linux with GCC when building with
302 timestamp profiling (--with-tsc): the preprocessor test for the PowerPC
303 support now looks for "__powerpc__" as well as "__ppc__": the latter seems to
304 only be present on OS X; the former is the correct one for Linux with GCC.

582 This prevents user-created self-referencing ordered dictionaries from
583 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001045- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1046 start byte and the continuation byte(s) are now considered invalid, instead
1047 of the number of bytes specified by the start byte.
1048 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1049 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1050 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1051 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001059- Issue #8748: Fix two issues with comparisons between complex and integer
1060 objects. (1) The comparison could incorrectly return True in some cases
1061 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1062 (2) The comparison raised an OverflowError for large integers, leading
1063 to unpredictable exceptions when combining integers and complex objects
1064 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001066- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00001203- Issue #1533: Fix inconsistency in range function argument processing: any
1204 non-float non-integer argument is now converted to an integer (if possible)
1205 using its __int__ method. Previously, only small arguments were treated this
1206 way; larger arguments (those whose __int__ was outside the range of a C long)
1207 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00001215 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00001216 benefit compared to the dynamic memory allocation fallback. Patch by
1217 Charles-François Natali.

1242 messages when accessing undefined class attributes because of the cheap
1243 inheritance with the underlying socket object. The cheap inheritance has been
1244 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00001245

Georg Brandlfee0f442010-05-22 21:26:21 +00001257- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1258 operation raises multiple signals and more than one of those signals is
1259 trapped, the specification determines the order in which the signals should be
1260 handled. In many cases this order wasn't being followed, leading to the wrong
1261 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00001262

1430
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001431- Issue #7301: Add environment variable $PYTHONWARNINGS.
1432
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001433- Issue #8329: Don't return the same lists from select.select when no fds are
1434 changed.
1435
Georg Brandlfee0f442010-05-22 21:26:21 +00001436- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001437 on 64-bit machines. The shift count for either left or right shift is
1438 permitted to be up to sys.maxsize.
1439
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001440- Ensure that tokenization of identifiers is not affected by locale.
1441
Georg Brandlfee0f442010-05-22 21:26:21 +00001442- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001443
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001444- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1445
Georg Brandlfee0f442010-05-22 21:26:21 +00001446- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1447 with a non-empty format string. This is an effort to future-proof user
1448 code. If a derived class does not currently implement __format__ but later
1449 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001450 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001451 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001452
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001453- Issue #8268: Old-style classes (not just instances) now support weak
1454 references.
1455
Georg Brandlfee0f442010-05-22 21:26:21 +00001456- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1457 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00001458
Victor Stinnerc7790ed2010-03-22 12:36:28 +00001459- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00001460
Benjamin Peterson96545892010-03-21 20:21:00 +00001461- Issue #6474: Make error message from passing an inadequate number of keyword
1462 arguments to a function correct.
1463
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001464- Issue #8164: Don't allow lambda functions to have a docstring.
1465
Victor Stinner66644262010-03-10 22:30:19 +00001466- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001467 (SIGINT). If an error occurs while importing the site module, the error is
1468 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001469 module.
1470
Collin Winter001a3952010-03-18 21:54:01 +00001471- Code objects now support weak references.

1474-------
1475
R. David Murray661303f2010-04-13 20:57:40 +00001476- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
1477
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001478- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001479 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1480 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001482- Issue #8310: Allow dis to examine new style classes.
1483
Georg Brandlfee0f442010-05-22 21:26:21 +00001484- Issue #8257: The Decimal construct now accepts a float instance directly,
1485 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001486
1487 >>> Decimal(1.1)
1488 Decimal('1.100000000000000088817841970012523233890533447265625')
1489
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001490- collections.Counter() now supports a subtract() method.
1491
Georg Brandlfee0f442010-05-22 21:26:21 +00001492- The functools module now has a total_ordering() class decorator to simplify
1493 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001494
Georg Brandlfee0f442010-05-22 21:26:21 +00001495- The functools module also adds cmp_to_key() as a tool to transition old-style
1496 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001497
Georg Brandlfee0f442010-05-22 21:26:21 +00001498- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1499 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001500
Georg Brandlfee0f442010-05-22 21:26:21 +00001501- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1502 InvalidOperation instead of returning False. (Comparisons involving a quiet
1503 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1504 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001505
Georg Brandlfee0f442010-05-22 21:26:21 +00001506- Issue #2531: Comparison operations between floats and Decimal instances now
1507 return a result based on the numeric values of the operands; previously they
1508 returned an arbitrary result based on the relative ordering of id(float) and
1509 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001510
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001511- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001512 argument `-` which tells it to read files to compile from stdin. Each line is
1513 read on demand and the named file is compiled immediately. (Original patch by
1514 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001515
Georg Brandlfee0f442010-05-22 21:26:21 +00001516- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1517 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001519- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1520 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001521 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001522
Georg Brandlfee0f442010-05-22 21:26:21 +00001523- Comparisons using one of <, <=, >, >= between a complex instance and a
1524 Fractions instance now raise TypeError instead of returning True/False. This
1525 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1526 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001527
Michael Foorde6410c52010-03-29 20:04:23 +00001528- Addition of ``WeakSet`` to the ``weakref`` module.

1536
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001537- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001538 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1539 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001540
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001541- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1542 deprecated.
1543
Georg Brandlfee0f442010-05-22 21:26:21 +00001544- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1545 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001546

1551 existing at the same time, causing a Unicode error when configuration code
1552 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001553
Georg Brandlfee0f442010-05-22 21:26:21 +00001554- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded

1558 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1559 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001581- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001582 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1583 log file to compute the next rollover time. If the log file does not exist,
1584 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001585

1593
Georg Brandlba83f822010-03-14 09:50:54 +00001594- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1595 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1596 This is a behavior change, so email's minor version number is now bumped, to
1597 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001625- Issue #8300: When passing a non-integer argument to struct.pack with any
1626 integer format code, struct.pack first attempts to convert the non-integer
1627 using its __index__ method. If that method is non-existent or raises
1628 TypeError it goes on to try the __int__ method, as described below.
1629
Georg Brandlba83f822010-03-14 09:50:54 +00001630- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1631 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1632 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001633 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1634 inconsistent: __int__ was used for some integer codes but not for others, and
1635 the set of integer codes for which it was used differed between native packing
1636 and standard packing.)

2041-----------------
2042
Georg Brandlba83f822010-03-14 09:50:54 +00002043- The ``__complex__()`` method is now looked up on the class of instances to

2048
Mark Dickinson1b34d252010-01-01 17:27:30 +00002049- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002050 DeprecationWarning when passed a float argument where an integer was expected.
2051 These functions and methods now raise TypeError instead. The majority of the
2052 effects of this change are in the extension modules, but some core functions
2053 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2054 and many unicode/str methods.

2069 least on IEEE 754 platforms), and in particular does not depend on the
2070 internal representation of a long.

2078
Georg Brandlba83f822010-03-14 09:50:54 +00002079 These executables now work properly with the arch(1) command: ``arch -ppc

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002222

2224 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00002237- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2238 decimal string that's guaranteed to round back to x under correct rounding
2239 (with round-half-to-even rounding mode). Previously it gave a string based on
2240 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2241 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2242 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002243
Georg Brandlba83f822010-03-14 09:50:54 +00002244- Issue #7117: On almost all platforms: float-to-string and string-to-float
2245 conversions within Python are now correctly rounded. Places these conversions
2246 occur include: str for floats and complex numbers; the float and complex
2247 constructors; old-style and new-style numeric formatting; serialization and
2248 deserialization of floats and complex numbers using marshal, pickle and json;
2249 parsing of float and imaginary literals in Python code; Decimal-to-float
2250 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002251
Georg Brandlba83f822010-03-14 09:50:54 +00002252 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2253 providing correctly-rounded strtod and dtoa C functions. This code is
2254 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2255 the C compiler. There may be a small number of platforms on which correct
2256 operation of this code cannot be guaranteed, so the code is not used: notably,
2257 this applies to platforms where the C double format is not IEEE 754 binary64,
2258 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2259 and Python's configure script is unable to determine how to change the FPU
2260 precision. On these platforms conversions use the platform strtod and dtoa,
2261 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002263- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2264 uses the correctly-rounded string <-> float conversions described above (when
2265 available), and so produces correctly rounded results that will display nicely
2266 under the float repr. There are two related small changes: (1) round now
2267 accepts any class with an ``__index__()`` method for its second argument (but
2268 no longer accepts floats for the second argument), and (2) an excessively
2269 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2270 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002412
Georg Brandlba83f822010-03-14 09:50:54 +00002413 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2414 (2) parsing of strings representing infinities and nans was locale aware; and
2415 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00002416
Georg Brandlba83f822010-03-14 09:50:54 +00002417- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2418 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2419 but with at least one decimal point and with a default precision
2420 of 12. Previously, the behavior the same but with a default precision of 6.
2421 This more closely matches ``str()``, and reduces surprises when adding
2422 alignment flags to the empty presentation type. This also affects the new
2423 complex.__format__ in the same way.
2424
2425- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2426 classtype's, even if it was None. property now inserts the __doc__ into the
2427 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002487- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002488 untrackable objects are not tracked by the garbage collector. This can reduce
2489 the size of collections and therefore the garbage collection overhead on

2497 internal representation of integers, for performance reasons. Base 2**30 is
2498 enabled by default on 64-bit machines. Add --enable-big-digits option to
2499 configure, which overrides the default. Add sys.long_info structseq to
2500 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00002601- Issue #4597: Fixed exception handling when the __exit__ function of a context
2602 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00002603
Georg Brandlba83f822010-03-14 09:50:54 +00002604- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00002605
Georg Brandlba83f822010-03-14 09:50:54 +00002606- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2607 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2608 instances. On a typical machine this saves 3 bytes of memory (on average) per
2609 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002610
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002611- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2612 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2613 instead of throwing a MemoryError.
2614
Georg Brandlba83f822010-03-14 09:50:54 +00002615- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2616 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00002617
Benjamin Petersonc078f922008-11-21 22:27:24 +00002618- Issue #4367: Python would segfault during compiling when the unicodedata
2619 module couldn't be imported and \N escapes were present.
2620
Georg Brandlba83f822010-03-14 09:50:54 +00002621- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2622 file objects with closefd=False. The file descriptor is still kept open but
2623 the file object behaves like a closed file. The ``FileIO`` object also got a
2624 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002625
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002626- Issue #4348: Some bytearray methods returned that didn't cause any change to
2627 the bytearray, returned the same bytearray instead of a copy.
2628
Georg Brandlba83f822010-03-14 09:50:54 +00002629- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00002630
Benjamin Peterson273c2332008-11-17 22:39:09 +00002631- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
2632
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002633- Issue #4048: The parser module now correctly validates relative imports.
2634
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002635- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
2636 exec statement.
2637
Georg Brandlba83f822010-03-14 09:50:54 +00002638- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
2639 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00002640
Benjamin Petersonbdca9422008-10-26 20:21:13 +00002641- Issue #4209: Enabling unicode_literals and the print_function in the same
2642 __future__ import didn't work.
2643
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002644- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002645 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002646
Georg Brandlba83f822010-03-14 09:50:54 +00002647- On windows, ``os.chdir()`` given unicode was not working if
2648 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2649 this code path is really executed because I cannot move to such directory on
2650 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002651
Georg Brandlba83f822010-03-14 09:50:54 +00002652- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2653 element is temporarily replaced with an equivalent frozenset. But the
2654 eventual KeyError would always report the empty ``frozenset()`` as the missing
2655 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00002656
Georg Brandlba83f822010-03-14 09:50:54 +00002657- Issue #4509: Various issues surrounding resize of bytearray objects to which
2658 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00002659
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00002660- Issue #4748: Lambda generators no longer return a value.
2661
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00002662- Issue #3582: Use native TLS functions on Windows
2663
Gregory P. Smithae91d092009-03-02 05:13:57 +00002664- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
2665
Georg Brandlba83f822010-03-14 09:50:54 +00002666- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
2667 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00002668
Matthias Klose91a3b9e2009-04-05 21:19:13 +00002669- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2670 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00002671
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002672- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2673 returned them on 64bit platforms.
2674
Walter Dörwalded960ac2009-05-03 22:36:33 +00002675- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2676 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2677 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2678 of using the replace error handler in PyUnicode_DecodeUTF8().
2679
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002680- Issue #3739: The unicode-internal encoder now reports the number of characters
2681 consumed like any other encoder (instead of the number of bytes).
2682
Georg Brandlba83f822010-03-14 09:50:54 +00002683- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2684 allocator will be automatically disabled when running under Valgrind. This
2685 gives improved memory leak detection when running under Valgrind, while taking
2686 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00002711- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
2712 ownership when the group is not forced, because the group may be different
2713 from the user's group and inherit from its container when the test is run.

Georg Brandlba83f822010-03-14 09:50:54 +00002755- Issue #6816: runpy now provides a run_path function that allows Python code to
2756 execute file paths that refer to source or compiled Python files as well as
2757 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00002758 __main__.py file. This allows applications that run other Python scripts to
2759 support the same flexibility as the CPython command line itself.
2760
Georg Brandlba83f822010-03-14 09:50:54 +00002761- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
2762 connection with another process, rather than looping endlessly. The default
2763 timeout is 20 seconds, which should be amply sufficient for local connections.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004051- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4052
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004053- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4054 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4055 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4056 ``printf`` function, whereas PyString_FromFormat has an independent
4057 implementation and uses "%zd" on all platforms for size_t values.
4058 This makes a difference on win64, where ``printf`` needs "%Id" to display
4059 64bit values.
4060
Benjamin Peterson97179b02008-09-09 20:55:01 +00004061- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4065 object; previously an int would be returned for small values. the __long__
4066 method is allowed to return either an int or a long, but the behaviour of
4067 float objects should not change to respect backward compatibility.
4068
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004069- Issue #3751: str.rpartition would perform a left-partition when called with
4070 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004075 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004076 was correctly parsed but parsing of subsequent arguments failed.
4077
Vinay Sajip35e3b032008-09-01 14:33:59 +00004078- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004079 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4080 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4081 when given a tuple of classes as second argument, were looking up
4082 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4083 type object.
4084
Neal Norwitz18aa3882008-08-24 05:04:52 +00004085- Fix crashes on memory allocation failure found with failmalloc.
4086
4087- Fix memory leaks found with valgrind and update suppressions file.
4088
4089- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004154 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4155 for catch_warnings() also led to an improvement in the raising of a

4228-----------------
4229
Guido van Rossumf8402962008-08-20 15:01:50 +00004230- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4231 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4232 extensions do not automatically benefit from the class attribute
4233 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4234 to their tp_flags field if they care. This is a backwards
4235 compatibility feature; in 3.0, all types will use the cache by
4236 default.
4237
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004238- Keyword arguments can now follow starred arguments. (``f(a, *args,
4239 keyword=23)`` is now valid syntax.)
4240
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004241- ctypes function pointers that are COM methods have a boolean True
4242 value again.
4243
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004244- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4245 by denying s# to parse objects that have a releasebuffer procedure,
4246 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00004248- Issue #3537: Fix an assertion failure when an empty but presized dict
4249 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00004251- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4252 ValueError consistently across platforms.
4253
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004254- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4255 (64bit Unix, for example), unichr() would truncate its argument and return
4256 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4257
Neal Norwitze7d8be82008-07-31 17:17:14 +00004258- Apply security patches from Apple.
4259
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004260- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00004263- Issue #1819: function calls with several named parameters are now on
4264 average 35% faster (as measured by pybench).
4265
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004266- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4267 the python debugger steps into a class statement: the free variables (local
4268 variables defined in an outer scope) would be deleted from the outer scope.
4269
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004270- Issue #2620: Overflow checking when allocating or reallocating memory
4271 was not always being done properly in some python types and extension
4272 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4273 all been updated to perform better checks and places in the code that
4274 would previously leak memory on the error path when such an allocation
4275 failed have been fixed.

4281
Benjamin Petersone977ad42008-08-20 01:42:01 +00004282- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4283 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4284
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004285- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4286 version reported by these tools does not necessarily follow the python
4287 version numbering scheme, so the module is less strict when parsing it.
4288
Nick Coghlanf70385a2008-08-18 12:42:46 +00004289- Issue #2235: Added Py3k warnings for types which will become unhashable
4290 under the stricter __hash__ inheritance rules in 3.0. Several types
4291 which did not meet the rules for hash invariants and were already
4292 unhashable in 3.0 have now been explicitly flagged as unhashable in
4293 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4294 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4295
Brett Cannon88f801d2008-08-18 00:46:22 +00004296- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4297 imported into the module but exposed as part of the module's API.
4298

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004305- Issue #3575: Incremental decoder's decode function now takes bytearray
4306 by using 's*' instead of 't#'.
4307
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004308- Issue #2222: Fixed reference leak when occurred os.rename()

4318 after a 302 response in the case of not going through a proxy.
4319
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004320- Issue #2676: in the email package, content-type parsing was hanging on
4321 pathological input because of quadratic or exponential behaviour of a
4322 regular expression.
4323
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004324- Issue #3476: binary buffered reading through the new "io" library is now
4325 thread-safe.
4326
Brett Cannonbf3157b2008-08-14 05:00:03 +00004327- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4328 since mimetools itself is deprecated. Because modules are cached, all
4329 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4330
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004331- Issue #3134: shutil referenced undefined WindowsError symbol.

4334 menu entries were not deleted.
4335
Brett Cannon83e81842008-08-09 23:30:55 +00004336- Copied the implementation of reduce() to _functools.reduce() to have a

4338
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004339- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4340 a MemoryError rather than silently stop the iteration.
4341
Guido van Rossum59ce9012008-08-09 14:55:34 +00004342- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4343 to _sre.compile() will now be rejected. This should not affect anybody
4344 since the re.compile() function never generates invalid re-bytecode.
4345
Skip Montanaroa032bf42008-08-08 22:52:51 +00004346- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4347 upon first access it can be automatically initialized from the csv file if
4348 it wasn't initialized during instantiation.
4349
Brett Cannon3aa2a492008-08-06 22:28:09 +00004350- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4351 the reload() built-in has been removed.
4352
Brett Cannon7e30b672008-08-04 21:52:25 +00004353- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004354 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4362 raised an AttributeError.
4363
Benjamin Peterson01a24322008-07-28 23:35:27 +00004364- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004365 asking for a specific length. This problem only affected files opened
4366 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004367

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004391- Issue #3394: zipfile.writestr sets external attributes when passed a
4392 file name rather than a ZipInfo instance, so files are extracted with
4393 mode 0600 rather than 000 under Unix.
4394
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004395- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4396 argument in python 2.5, this broke code that subclassed Popen to include its
4397 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004407- Issue #2235: the C API function PyObject_HashNotImplemented and its
4408 interaction with the tp_hash slot (added in 2.6b2) are now documented
4409
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004410- Issue #643841: The language reference now provides more detailed
4411 coverage of the lookup process for special methods. The disclaimers
4412 regarding lack of coverage of new-style classes have also been
4413 removed, since the coverage is now fairly reasonable.

4417================================
4418
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004419*Release date: 17-Jul-2008*
4420
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004421Core and Builtins
4422-----------------
4423
Georg Brandl3e483f62008-07-16 22:57:41 +00004424- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4425 its methods now allow for items objects that can be converted to
4426 an integer using operator.index().
4427
Mark Dickinson64b7e502008-07-16 09:40:03 +00004428- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4429 produced a ValueError instead of giving the correct float.
4430
Eric Smitha5fa5a22008-07-16 00:11:49 +00004431- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4432 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4433
Mark Dickinson7103aa42008-07-15 19:08:33 +00004434- Issue #3008: the float type has a new instance method 'float.hex'
4435 and a new class method 'float.fromhex' to convert floating-point
4436 numbers to and from hexadecimal strings, respectively.
4437
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004438- Issue #2235: __hash__ is once again inherited by default. To allow
4439 collections.Hashable to remain meaningful in the presence of the
4440 default hash implementation (object.__hash__), it is now possible
4441 to explicit block inheritance of hash by setting __hash__=None at
4442 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4443 level.
4444
Nick Coghlanb028f502008-07-13 14:52:36 +00004445- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4446 the parent module cannot be found while performing an absolute import.
4447 This means that an incorrectly defined __package__ attribute will
4448 now only prevent relative imports in that module rather than causing
4449 all imports from that module to fail.
4450
Nick Coghlan14ff9942008-07-08 14:21:42 +00004451- Issue #2517: Allow unicode messages in Exceptions again by correctly
4452 bypassing the instance dictionary when looking up __unicode__ on
4453 new-style classes.
4454
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004455- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4456 set to a custom object whose write() method happens to install
4457 another file in sys.stdout.
4458
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004459- Issue #3088: Corrected a race condition in classes derived from
4460 threading.local: the first member set by a thread could be saved in
4461 another thread's dictionary.
4462
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004463- Issue #3004: Minor change to slice.indices(): the start and stop
4464 arguments are now treated identically, making the behaviour easier
4465 to describe and understand. For example, slice(None, -10,
4466 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4467 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4468 10, -1).
4469
Georg Brandl278fc502008-07-19 12:46:12 +00004470- Issue #3219: Calling a function with repeated keyword arguments,
4471 f(a=2, a=23), would not cause a syntax error. This was a regression
4472 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004473
Georg Brandl278fc502008-07-19 12:46:12 +00004474- Issue #2862: Make int and float freelist management consistent with
4475 other freelists. Changes their CompactFreeList apis into
4476 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004477

4479-------
4480
Thomas Heller57adf222008-08-14 19:10:48 +00004481- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4482 api functions without holding the GIL, which could lead to a fatal
4483 error when they failed.
4484
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004485- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004493- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4494 ForkingPickler.register() to resolve conflict with ctypes.
4495
Vinay Sajip51e65192008-07-18 09:01:10 +00004496- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004497
Thomas Heller880f5292008-07-15 19:39:38 +00004498- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4499 a valid dlerror() message.
4500
Thomas Heller2bad6572008-07-15 17:19:50 +00004501- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4502 incomplete structure was created.
4503
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004504- Issue #3339: dummy_thread.acquire() should not return None.

4507
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004508- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004509
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004510- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4511 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004512 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004513 content-length. The problem had been corrected in the 2.4 branch, but never
4514 merged into trunk.
4515
Georg Brandle78fbcc2008-07-05 10:13:36 +00004516- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00004524 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004525
Vinay Sajip51e65192008-07-18 09:01:10 +00004526- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004527 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004528
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004529- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4530 handling is now the same as that of other special attributes like __name__).
4531
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004532- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4533 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004922 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004923
4924 This is controlled by the configure argument ``--with-universal-archs``:
4925
4926 - ``--with-universal-archs=all``: install 4-way universal
4927
4928 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4929
4930 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4931
4932 This option should be used in combination with ``--enable-universalsdk=``.
4933
4934 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 +00004984- Issue #1631171: Re-implement the 'warnings' module in C (the
4985 original Python code has been kept as backup). This will allow for
4986 using the 'warning's machinery in such places as the parser where
4987 use of pure Python code is not possible. Both the ``showarning()``
4988 and ``formatwarning()`` gain an optional 'line' argument which is
4989 not called by default for backwards-compatibility reasons. Setting
4990 ``warnings.showwarning()`` to an implementation that lacks support
4991 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005054- Issue #2550: The approach used by client/server code for obtaining
5055 ports to listen on in network-oriented tests has been refined in an
5056 effort to facilitate running multiple instances of the entire
5057 regression test suite in parallel without issue.
5058 test_support.bind_port() has been fixed such that it will always
5059 return a unique port -- which wasn't always the case with the
5060 previous implementation, especially if socket options had been set
5061 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5062 new implementation of bind_port() will actually raise an exception
5063 if it is passed an AF_INET/SOCK_STREAM socket with either the
5064 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5065 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5066 the socket it's been passed. This currently only applies to
5067 Windows. This option prevents any other sockets from binding to the
5068 host/port we've bound to, thus removing the possibility of the
5069 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5070 when a second SOCK_STREAM socket binds and accepts to a host/port
5071 that's already been bound by another socket. The optional preferred
5072 port parameter to bind_port() has been removed. Under no
5073 circumstances should tests be hard coding ports!
5074
5075 test_support.find_unused_port() has also been introduced, which will
5076 pass a temporary socket object to bind_port() in order to obtain an
5077 unused port. The temporary socket object is then closed and
5078 deleted, and the port is returned. This method should only be used
5079 for obtaining an unused port in order to pass to an external program
5080 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5081 a parameter to a server-oriented class that doesn't give you direct
5082 access to the underlying socket used.
5083
5084 Finally, test_support.HOST has been introduced, which should be used
5085 for the host argument of any relevant socket calls (i.e. bind and
5086 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005087
5088 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005089 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

5091 test_asynchat and test_socket_ssl.
5092
Georg Brandl3ee81df2008-05-17 18:14:43 +00005093 It is now possible for multiple instances of the regression test
5094 suite to run in parallel without issue.

5361-----------------
5362
Fred Drakea8ee94b2008-03-01 02:45:07 +00005363- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005364 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005365
Georg Brandlad61bc82008-02-23 15:11:18 +00005366- Issue #2067: file.__exit__() now calls subclasses' close() method.
5367
5368- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005369
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005370- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005371 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005372
Eric Smitha73fbe72008-02-23 03:09:44 +00005373- Added the future_builtins module, which contains hex() and oct().
5374 These are the PEP 3127 version of these functions, designed to be
5375 compatible with the hex() and oct() builtins from Python 3.0. They
5376 differ slightly in their output formats from the existing, unchanged
5377 Python 2.6 builtins. The expected usage of the future_builtins
5378 module is:
5379 from future_builtins import hex, oct
5380
Eric Smith7ef40bf2008-02-20 23:34:22 +00005381- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5382 exponents for exponents with absolute value < 100. Follows C99
5383 standard. This is a change on Windows, which would use 3 digits.
5384 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5385 so that any alterations it does to the resulting string will be
5386 available in stringlib/formatter.h (for float.__format__).
5387
Eric Smith5a3c1352008-02-19 13:21:56 +00005388- Implemented PEP 3101, Advanced String Formatting. This adds a new
5389 builtin format(); a format() method for str and unicode; a
5390 __format__() method to object, str, unicode, int, long, float, and
5391 datetime; the class string.Formatter; and the C API
5392 PyObject_Format().
5393
Georg Brandl3ee81df2008-05-17 18:14:43 +00005394- Fixed several potential crashes, all caused by specially crafted
5395 __del__ methods exploiting objects in temporarily inconsistent
5396 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005397
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005398- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005399 prevent a possible crash: an Abstract Base Class would try to access
5400 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005401
Georg Brandl3ee81df2008-05-17 18:14:43 +00005402- Fixed repr() and str() of complex numbers with infinity or nan as
5403 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005404
Georg Brandl3ee81df2008-05-17 18:14:43 +00005405- Clear all free lists during a gc.collect() of the highest generation
5406 in order to allow pymalloc to free more arenas. Python may give back
5407 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005408
Georg Brandl3ee81df2008-05-17 18:14:43 +00005409- Issue #2045: Fix an infinite recursion triggered when printing a
5410 subclass of collections.defaultdict, if its default_factory is set
5411 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005412
Christian Heimesf75dbef2008-02-08 00:11:31 +00005413- Fixed a minor memory leak in dictobject.c. The content of the free
5414 list was not freed on interpreter shutdown.
5415
Georg Brandl21e99f42010-03-07 15:23:59 +00005416- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005417 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005418
Georg Brandl3ee81df2008-05-17 18:14:43 +00005419- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5420 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005421 to compact the internal free lists of pre-allocted ints and floats.
5422
Georg Brandl3ee81df2008-05-17 18:14:43 +00005423- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5424 calls. Python expected the return type int but the fork familie
5425 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005426
Georg Brandl3ee81df2008-05-17 18:14:43 +00005427- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5428 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005429
Georg Brandl3ee81df2008-05-17 18:14:43 +00005430- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5431 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005432
Georg Brandl3ee81df2008-05-17 18:14:43 +00005433- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5434 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005435
Georg Brandl3ee81df2008-05-17 18:14:43 +00005436- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5437 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005438
Georg Brandl3ee81df2008-05-17 18:14:43 +00005439- Patch #1473257: generator objects gain a gi_code attribute. This is
5440 the same object as the func_code attribute of the function that
5441 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005442
Georg Brandl3ee81df2008-05-17 18:14:43 +00005443- Issue #1920: "while 0" statements were completely removed by the
5444 compiler, even in the presence of an "else" clause, which is
5445 supposed to be run when the condition is false. Now the compiler
5446 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005447
Guido van Rossumeead05f2008-01-24 18:21:02 +00005448- A few crashers fixed: weakref_in_del.py (issue #1377858);
5449 loosing_dict_ref.py (issue #1303614, test67.py);
5450 borrowed_ref_[34].py (not in tracker).
5451
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005452- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005453 suppressed while an extension is loaded by calling SetErrorMode in
5454 dynload_win.c. The error is still reported properly.
5455
Georg Brandl3ee81df2008-05-17 18:14:43 +00005456- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005457 several extension methods and modules do not work without unicode
5458 support.
5459
Georg Brandl26543b12008-01-21 18:36:51 +00005460- Issue #1882: when compiling code from a string, encoding cookies in the
5461 second line of code were not always recognized correctly.
5462
Georg Brandl14404b62008-01-19 19:27:05 +00005463- Issue #1679: "0x" was taken as a valid integer literal.
5464
Georg Brandl6caad7d2008-01-26 14:19:22 +00005465- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005466 added.
5467
Christian Heimesc94e2b52008-01-14 04:13:37 +00005468- sys.float_info / PyFloat_GetInfo: The floating point information
5469 object was converted from a dict to a specialized structseq object.
5470
Georg Brandl3ee81df2008-05-17 18:14:43 +00005471- Patch #1816: Added sys.flags structseq. It exposes the status of
5472 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005473
Georg Brandl3ee81df2008-05-17 18:14:43 +00005474- Objects/structseq.c: Implemented new structseq representation. The
5475 patch makes structseqs (e.g. the return value of os.stat) more
5476 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005477
Georg Brandl3ee81df2008-05-17 18:14:43 +00005478- Patch #1700288: added a type attribute cache that caches method
5479 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005480
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005481- Bug #1776: __import__() no longer accepts filenames on any platform.
5482 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005483
Georg Brandlaed6c662008-01-07 17:25:53 +00005484- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5485
Georg Brandl3ee81df2008-05-17 18:14:43 +00005486- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5487 envvar and sys.dont_write_bytecode attribute. All these can be set
5488 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005489
Georg Brandl3ee81df2008-05-17 18:14:43 +00005490- Improve some exception messages when Windows fails to load an
5491 extension module. Now we get for example '%1 is not a valid Win32
5492 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005493
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005496- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5497 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005498
Christian Heimes0a8143f2007-12-18 23:22:54 +00005499- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005500 and INF. float("nan"), float("inf") and float("-inf") now work on
5501 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005502
Georg Brandl3ee81df2008-05-17 18:14:43 +00005503- Compiler now generates simpler and faster code for dictionary
5504 literals. The oparg for BUILD_MAP now indicates an estimated
5505 dictionary size. There is a new opcode, STORE_MAP, for adding
5506 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005507
Georg Brandl3ee81df2008-05-17 18:14:43 +00005508- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005513- Issue #1538: Avoid copying string in split/rsplit if the split char
5514 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005515
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005516- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005517 SystemError.
5518
Nick Coghlanef01d822007-12-03 12:55:17 +00005519- PEP 366: Allow explicit relative imports when executing modules

5521 __package__ attribute.
5522
Georg Brandl3ee81df2008-05-17 18:14:43 +00005523- Issue #1402: Fix a crash on exit, when another thread is still
5524 running, and if the deallocation of its frames somehow calls the
5525 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005526

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005530 attribute of an empty cell object.
5531
Georg Brandl3ee81df2008-05-17 18:14:43 +00005532- Issue #1460: The utf-7 incremental decoder did not accept truncated
5533 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005534
Georg Brandl3ee81df2008-05-17 18:14:43 +00005535- Patch #1739468: Directories and zipfiles containing a __main__.py
5536 file can now be directly executed by passing their name to the
5537 interpreter. The directory/zipfile is automatically inserted as the
5538 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005539
Georg Brandl3ee81df2008-05-17 18:14:43 +00005540- Issue #1265: Fix a problem with sys.settrace, if the tracing
5541 function uses a generator expression when at the same time the
5542 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005543
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005544- sets and frozensets now have an isdisjoint() method.
5545
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005546- optimize the performance of builtin.sum().
5547
Neal Norwitz44f326e2007-10-05 05:29:17 +00005548- Fix warnings found by the new version of the Coverity checker.
5549
Georg Brandl21e99f42010-03-07 15:23:59 +00005550- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005551 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5552 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005553
Georg Brandl3ee81df2008-05-17 18:14:43 +00005554- Issue #1686386: Tuple's tp_repr did not take into account the
5555 possibility of having a self-referential tuple, which is possible
5556 from C code. Nor did object's tp_str consider that a type's tp_str
5557 could do something that could lead to an inifinite recursion.
5558 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5559 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005560
Georg Brandl3ee81df2008-05-17 18:14:43 +00005561- Issue #1164: It was possible to trigger deadlock when using the
5562 'print' statement to write to a file since the GIL was not released
5563 as needed. Now PyObject_Print() does the right thing along with
5564 various tp_print implementations of the built-in types and those in
5565 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005566
Georg Brandl3ee81df2008-05-17 18:14:43 +00005567- Issue #1147: Exceptions were directly allowing string exceptions in
5568 their throw() method even though string exceptions no longer
5569 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005570

Brett Cannon1e534b52007-09-07 04:18:30 +00005574- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005575 PyObject_Call() never calling back out to Python code to trigger
5576 recursion depth updates/checks. Required the creation of a static
5577 RuntimeError instance in case normalizing an exception put the
5578 recursion check value past its limit. Fixes crashers
5579 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005580

Neal Norwitz0ac60192007-05-27 04:08:54 +00005594- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005595 __*__ attributes. (Some already existed, e.g., __doc__ and
5596 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005597
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005598- Add -3 option to the interpreter to warn about features that are

5602 calls.
5603
Collin Winter62903052007-05-18 23:11:24 +00005604- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005605 "except E as target:". This is to provide forwards compatibility
5606 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005607
Brett Cannon229cee22007-05-05 01:34:02 +00005608- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005610- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005611 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005613- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005614 setting a plain string, ie don't expand to single letter identifiers.
5615
Raymond Hettinger13936692007-04-11 18:40:58 +00005616- Request #1191699: Slices can now be pickled.

5626
Guido van Rossum143b5642007-03-23 04:58:42 +00005627- Bug #1683368: The object.__init__() and object.__new__() methods are
5628 now stricter in rejecting excess arguments. The only time when
5629 either allows excess arguments is when it is not overridden and the
5630 other one is. For backwards compatibility, when both are
5631 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005632 warning later). Also, type.__init__() insists on the same signature
5633 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005634
Georg Brandl3ee81df2008-05-17 18:14:43 +00005635- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5636 object to complex using its __complex__() method before falling back
5637 to the __float__() method. Therefore, the functions in the cmath
5638 module now can operate on objects that define a __complex__()
5639 method.

5656
Georg Brandl7b9c5552007-03-12 14:30:05 +00005657- Bug #1678647: write a newline after printing an exception in any
5658 case, even when converting the value to a string failed.
5659
Georg Brandl871f1bc2007-03-12 13:17:36 +00005660- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005661 its argument, if it exists. If not, it will work like before. This
5662 allows customizing the output of dir() in the presence of a
5663 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005664
Collin Winter276887b2007-03-12 16:11:39 +00005665- Patch #922167: Python no longer segfaults when faced with infinitely
5666 self-recursive reload() calls (as reported by bug #742342).

5672 parthensized forms. This means complex(repr(x)) now works instead of
5673 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005674
Georg Brandlaa2321b2007-03-07 00:40:28 +00005675- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005676 makes the filenames the warning module prints much more sensible
5677 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005678

Georg Brandl0fca97a2007-03-05 22:28:08 +00005690- Patch #1674228: when assigning a slice (old-style), check for the
5691 sq_ass_slice instead of the sq_slice slot.
5692
Georg Brandl3ee81df2008-05-17 18:14:43 +00005693- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006228 AttributeError instead of an IOError when the server's response
6229 didn't contain a valid HTTP status line.

6320 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006605- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6606 with RFC 3207 and forgets any knowledge obtained from the server not
6607 obtained from the TLS negotiation itself. Patch contributed by Bill
6608 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006609
Georg Brandl3ee81df2008-05-17 18:14:43 +00006610- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006611 that the SMTP.starttls() caller no longer needs to call ehlo()
6612 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006613 does not claim to support starttls. Adds the
6614 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6695 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6696 silently miscode subclasses of those types. Now, it raises a
6697 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006698

Georg Brandl3ee81df2008-05-17 18:14:43 +00006713 time so that opening a database previously created with the DB_DUP
6714 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6715 opens. Specifically: dictionary assignment to a DB object will
6716 replace all values for a given key when the database allows
6717 duplicate values. DB users should use DB.put(k, v) when they want
6718 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006719

6725 characters with ASCII value less than 32. Also, it correctly quotes
6726 dots only if they occur on a single line, as opposed to the previous
6727 behavior of quoting dots if they are the second character of any
6728 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006729

Georg Brandl3ee81df2008-05-17 18:14:43 +00007058- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7059 to ``PyTuple_SetItem``, it can be used to populate a brand new
7060 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007061
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007062- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007064- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7065 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7066 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007067
7068- Patch #1720595: add T_BOOL to the range of structmember types.
7069
7070- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7071 ``PyFloat_GetInfo()`` to the float API.
7072
Georg Brandl3ee81df2008-05-17 18:14:43 +00007073- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7074 of w# format code incorrectly truncated the length to an int, even
7075 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7076 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007077
Georg Brandl3ee81df2008-05-17 18:14:43 +00007078- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7079 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007081- PEP 3123: Provide forward compatibility with Python 3.0, while
7082 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7083 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007084
Georg Brandl3ee81df2008-05-17 18:14:43 +00007085- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7086 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007087
7088- Patch #1733960: Allow T_LONGLONG to accept ints.
7089
7090- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7091
Christian Heimes000a0742008-01-03 22:16:32 +00007092- Added a new API function ``PyImport_ImportModuleNoBlock``.
7093
Georg Brandl6caad7d2008-01-26 14:19:22 +00007094- Bug #1637022: Prefix AST symbols with _Py_.
7095
7096- Fix some leftovers from the conversion from int to Py_ssize_t
7097 (relevant to strings and sequences of more than 2**31 items).
7098
7099- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7100 outside of pystate.c and should not be necessary.
7101
Georg Brandl3ee81df2008-05-17 18:14:43 +00007102- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7103 absolute imports. In earlier versions they might have used relative
7104 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007105
Georg Brandl3ee81df2008-05-17 18:14:43 +00007106- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7107 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007108
Georg Brandl3ee81df2008-05-17 18:14:43 +00007109- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7110 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007116- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7117 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7118 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7119 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007120
Georg Brandl3ee81df2008-05-17 18:14:43 +00007121- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00007132- buildtools now raises a DeprecationWarning.
7133
Georg Brandl3ee81df2008-05-17 18:14:43 +00007134- Removed the macfs module. It had been deprecated since Python 2.5.
7135 This lead to the deprecation of macostools.touched() as it relied
7136 solely on macfs and was a no-op under OS X.
