David Malcolm4c29e1c2011-01-06 17:39:24 +0000303- Issue #10655: Fix the build on PowerPC on Linux with GCC when building with
304 timestamp profiling (--with-tsc): the preprocessor test for the PowerPC
305 support now looks for "__powerpc__" as well as "__ppc__": the latter seems to
306 only be present on OS X; the former is the correct one for Linux with GCC.

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

1046
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001047- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1048 start byte and the continuation byte(s) are now considered invalid, instead
1049 of the number of bytes specified by the start byte.
1050 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1051 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1052 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1053 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001061- Issue #8748: Fix two issues with comparisons between complex and integer
1062 objects. (1) The comparison could incorrectly return True in some cases
1063 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1064 (2) The comparison raised an OverflowError for large integers, leading
1065 to unpredictable exceptions when combining integers and complex objects
1066 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001068- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00001205- Issue #1533: Fix inconsistency in range function argument processing: any
1206 non-float non-integer argument is now converted to an integer (if possible)
1207 using its __int__ method. Previously, only small arguments were treated this
1208 way; larger arguments (those whose __int__ was outside the range of a C long)
1209 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00001217 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00001218 benefit compared to the dynamic memory allocation fallback. Patch by

1245 inheritance with the underlying socket object. The cheap inheritance has been
1246 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00001259- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1260 operation raises multiple signals and more than one of those signals is
1261 trapped, the specification determines the order in which the signals should be
1262 handled. In many cases this order wasn't being followed, leading to the wrong
1263 Python exception being raised.

1430Core and Builtins
1431-----------------
1432
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001433- Issue #7301: Add environment variable $PYTHONWARNINGS.
1434
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001435- Issue #8329: Don't return the same lists from select.select when no fds are
1436 changed.
1437
Georg Brandlfee0f442010-05-22 21:26:21 +00001438- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001439 on 64-bit machines. The shift count for either left or right shift is
1440 permitted to be up to sys.maxsize.
1441
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001442- Ensure that tokenization of identifiers is not affected by locale.
1443
Georg Brandlfee0f442010-05-22 21:26:21 +00001444- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001445
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001446- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1447
Georg Brandlfee0f442010-05-22 21:26:21 +00001448- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1449 with a non-empty format string. This is an effort to future-proof user
1450 code. If a derived class does not currently implement __format__ but later
1451 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001452 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001453 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001454
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001455- Issue #8268: Old-style classes (not just instances) now support weak
1456 references.
1457
Georg Brandlfee0f442010-05-22 21:26:21 +00001458- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1459 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00001460
Victor Stinnerc7790ed2010-03-22 12:36:28 +00001461- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00001462
Benjamin Peterson96545892010-03-21 20:21:00 +00001463- Issue #6474: Make error message from passing an inadequate number of keyword
1464 arguments to a function correct.
1465
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001466- Issue #8164: Don't allow lambda functions to have a docstring.
1467
Victor Stinner66644262010-03-10 22:30:19 +00001468- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001469 (SIGINT). If an error occurs while importing the site module, the error is
1470 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001471 module.
1472
Collin Winter001a3952010-03-18 21:54:01 +00001473- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00001478- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
1479
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001480- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001481 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1482 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001483
Benjamin Peterson76a23c12010-04-04 23:23:22 +00001484- Issue #8310: Allow dis to examine new style classes.
1485
Georg Brandlfee0f442010-05-22 21:26:21 +00001486- Issue #8257: The Decimal construct now accepts a float instance directly,
1487 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001488
1489 >>> Decimal(1.1)
1490 Decimal('1.100000000000000088817841970012523233890533447265625')
1491
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001492- collections.Counter() now supports a subtract() method.
1493
Georg Brandlfee0f442010-05-22 21:26:21 +00001494- The functools module now has a total_ordering() class decorator to simplify
1495 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001496
Georg Brandlfee0f442010-05-22 21:26:21 +00001497- The functools module also adds cmp_to_key() as a tool to transition old-style
1498 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001499
Georg Brandlfee0f442010-05-22 21:26:21 +00001500- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1501 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001502
Georg Brandlfee0f442010-05-22 21:26:21 +00001503- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1504 InvalidOperation instead of returning False. (Comparisons involving a quiet
1505 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1506 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001507
Georg Brandlfee0f442010-05-22 21:26:21 +00001508- Issue #2531: Comparison operations between floats and Decimal instances now
1509 return a result based on the numeric values of the operands; previously they
1510 returned an arbitrary result based on the relative ordering of id(float) and
1511 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001512
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001513- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001514 argument `-` which tells it to read files to compile from stdin. Each line is
1515 read on demand and the named file is compiled immediately. (Original patch by
1516 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001517
Georg Brandlfee0f442010-05-22 21:26:21 +00001518- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1519 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001521- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1522 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001523 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001524
Georg Brandlfee0f442010-05-22 21:26:21 +00001525- Comparisons using one of <, <=, >, >= between a complex instance and a
1526 Fractions instance now raise TypeError instead of returning True/False. This
1527 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1528 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001529
Michael Foorde6410c52010-03-29 20:04:23 +00001530- Addition of ``WeakSet`` to the ``weakref`` module.

1538
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001539- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001540 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1541 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001542
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001543- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1544 deprecated.
1545
Georg Brandlfee0f442010-05-22 21:26:21 +00001546- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1547 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001548

1553 existing at the same time, causing a Unicode error when configuration code
1554 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001555
Georg Brandlfee0f442010-05-22 21:26:21 +00001556- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
1557 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00001558
Antoine Pitroueee91cd2010-03-26 19:27:16 +00001559- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
1560 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1561 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00001562
Florent Xiclunacf82fa62010-03-21 12:27:20 +00001563- Issue #8179: Fix macpath.realpath() on a non-existing path.

1569 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00001570
Matthias Klose8b411682010-03-16 10:48:52 +00001571- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
1572 with Tcl/Tk-8.5.

1577 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00001578
Georg Brandlfee0f442010-05-22 21:26:21 +00001579- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001583- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001584 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1585 log file to compute the next rollover time. If the log file does not exist,
1586 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001587
Georg Brandlba83f822010-03-14 09:50:54 +00001588- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

1595
Georg Brandlba83f822010-03-14 09:50:54 +00001596- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1597 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1598 This is a behavior change, so email's minor version number is now bumped, to
1599 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00001600

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001627- Issue #8300: When passing a non-integer argument to struct.pack with any
1628 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00001632- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1633 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1634 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001635 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1636 inconsistent: __int__ was used for some integer codes but not for others, and
1637 the set of integer codes for which it was used differed between native packing
1638 and standard packing.)

2043-----------------
2044
Georg Brandlba83f822010-03-14 09:50:54 +00002045- The ``__complex__()`` method is now looked up on the class of instances to
2046 make it consistent with other special methods.

2050
Mark Dickinson1b34d252010-01-01 17:27:30 +00002051- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002052 DeprecationWarning when passed a float argument where an integer was expected.
2053 These functions and methods now raise TypeError instead. The majority of the
2054 effects of this change are in the extension modules, but some core functions
2055 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2056 and many unicode/str methods.

2071 least on IEEE 754 platforms), and in particular does not depend on the
2072 internal representation of a long.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002224

Georg Brandlba83f822010-03-14 09:50:54 +00002239- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2240 decimal string that's guaranteed to round back to x under correct rounding
2241 (with round-half-to-even rounding mode). Previously it gave a string based on
2242 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2243 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2244 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002245
Georg Brandlba83f822010-03-14 09:50:54 +00002246- Issue #7117: On almost all platforms: float-to-string and string-to-float
2247 conversions within Python are now correctly rounded. Places these conversions
2248 occur include: str for floats and complex numbers; the float and complex
2249 constructors; old-style and new-style numeric formatting; serialization and
2250 deserialization of floats and complex numbers using marshal, pickle and json;
2251 parsing of float and imaginary literals in Python code; Decimal-to-float
2252 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002253
Georg Brandlba83f822010-03-14 09:50:54 +00002254 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2255 providing correctly-rounded strtod and dtoa C functions. This code is
2256 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2257 the C compiler. There may be a small number of platforms on which correct
2258 operation of this code cannot be guaranteed, so the code is not used: notably,
2259 this applies to platforms where the C double format is not IEEE 754 binary64,
2260 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2261 and Python's configure script is unable to determine how to change the FPU
2262 precision. On these platforms conversions use the platform strtod and dtoa,
2263 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002265- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2266 uses the correctly-rounded string <-> float conversions described above (when
2267 available), and so produces correctly rounded results that will display nicely
2268 under the float repr. There are two related small changes: (1) round now
2269 accepts any class with an ``__index__()`` method for its second argument (but
2270 no longer accepts floats for the second argument), and (2) an excessively
2271 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2272 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002366- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
2367 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
2368 of stdint.h on that platform.
Mark Dickinson2f865b92009-06-30 15:32:30 +00002369

2404 literals.
Mark Dickinsona4e0efa2009-05-20 18:43:07 +00002405

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002413- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00002414
Georg Brandlba83f822010-03-14 09:50:54 +00002415 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2416 (2) parsing of strings representing infinities and nans was locale aware; and
2417 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00002418
Georg Brandlba83f822010-03-14 09:50:54 +00002419- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2420 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2421 but with at least one decimal point and with a default precision
2422 of 12. Previously, the behavior the same but with a default precision of 6.
2423 This more closely matches ``str()``, and reduces surprises when adding
2424 alignment flags to the empty presentation type. This also affects the new
2425 complex.__format__ in the same way.
2426
2427- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2428 classtype's, even if it was None. property now inserts the __doc__ into the
2429 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002489- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002490 untrackable objects are not tracked by the garbage collector. This can reduce
2491 the size of collections and therefore the garbage collection overhead on
2492 long-running programs, depending on their particular use of datatypes.

2499 internal representation of integers, for performance reasons. Base 2**30 is
2500 enabled by default on 64-bit machines. Add --enable-big-digits option to
2501 configure, which overrides the default. Add sys.long_info structseq to
2502 provide information about the internal format.

2622
Georg Brandlba83f822010-03-14 09:50:54 +00002623- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2624 file objects with closefd=False. The file descriptor is still kept open but
2625 the file object behaves like a closed file. The ``FileIO`` object also got a
2626 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002646- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002649- On windows, ``os.chdir()`` given unicode was not working if
2650 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2651 this code path is really executed because I cannot move to such directory on
2652 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002654- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2655 element is temporarily replaced with an equivalent frozenset. But the
2656 eventual KeyError would always report the empty ``frozenset()`` as the missing
2657 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002677- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2678 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2679 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2680 of using the replace error handler in PyUnicode_DecodeUTF8().
2681
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002682- Issue #3739: The unicode-internal encoder now reports the number of characters

2684
Georg Brandlba83f822010-03-14 09:50:54 +00002685- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2687 gives improved memory leak detection when running under Valgrind, while taking
2688 advantage of pymalloc at other times.

3855 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3856 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00003911 leak-chasing test runs give sensible results. The previous method of reaping
3912 threads could return successfully while some Thread objects were still

4054
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004055- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4056 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4057 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4058 ``printf`` function, whereas PyString_FromFormat has an independent
4059 implementation and uses "%zd" on all platforms for size_t values.
4060 This makes a difference on win64, where ``printf`` needs "%Id" to display
4061 64bit values.

4067 object; previously an int would be returned for small values. the __long__
4068 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004078 was correctly parsed but parsing of subsequent arguments failed.
4079
Vinay Sajip35e3b032008-09-01 14:33:59 +00004080- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004081 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4082 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4083 when given a tuple of classes as second argument, were looking up
4084 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4085 type object.

4230-----------------
4231
Guido van Rossumf8402962008-08-20 15:01:50 +00004232- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4233 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4234 extensions do not automatically benefit from the class attribute
4235 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4236 to their tp_flags field if they care. This is a backwards
4237 compatibility feature; in 3.0, all types will use the cache by
4238 default.
4239
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004240- Keyword arguments can now follow starred arguments. (``f(a, *args,
4241 keyword=23)`` is now valid syntax.)
4242
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004243- ctypes function pointers that are COM methods have a boolean True
4244 value again.

4254 ValueError consistently across platforms.
4255
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004256- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4257 (64bit Unix, for example), unichr() would truncate its argument and return
4258 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00004260- Apply security patches from Apple.
4261
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004262- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4263 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4264
Antoine Pitrou92f82162008-07-25 22:22:08 +00004265- Issue #1819: function calls with several named parameters are now on
4266 average 35% faster (as measured by pybench).
4267
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004268- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4269 the python debugger steps into a class statement: the free variables (local
4270 variables defined in an outer scope) would be deleted from the outer scope.
4271
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004272- Issue #2620: Overflow checking when allocating or reallocating memory
4273 was not always being done properly in some python types and extension
4274 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4275 all been updated to perform better checks and places in the code that
4276 would previously leak memory on the error path when such an allocation
4277 failed have been fixed.

4283
Benjamin Petersone977ad42008-08-20 01:42:01 +00004284- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4285 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4286
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004287- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4288 version reported by these tools does not necessarily follow the python
4289 version numbering scheme, so the module is less strict when parsing it.
4290
Nick Coghlanf70385a2008-08-18 12:42:46 +00004291- Issue #2235: Added Py3k warnings for types which will become unhashable
4292 under the stricter __hash__ inheritance rules in 3.0. Several types
4293 which did not meet the rules for hash invariants and were already
4294 unhashable in 3.0 have now been explicitly flagged as unhashable in
4295 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4296 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4297
Brett Cannon88f801d2008-08-18 00:46:22 +00004298- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4299 imported into the module but exposed as part of the module's API.

Antoine Pitroub90a8be2008-08-15 21:03:21 +00004322- Issue #2676: in the email package, content-type parsing was hanging on
4323 pathological input because of quadratic or exponential behaviour of a
4324 regular expression.

Brett Cannonbf3157b2008-08-14 05:00:03 +00004329- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4330 since mimetools itself is deprecated. Because modules are cached, all
4331 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4332
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004333- Issue #3134: shutil referenced undefined WindowsError symbol.

4342 a MemoryError rather than silently stop the iteration.
4343
Guido van Rossum59ce9012008-08-09 14:55:34 +00004344- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4345 to _sre.compile() will now be rejected. This should not affect anybody
4346 since the re.compile() function never generates invalid re-bytecode.
4347
Skip Montanaroa032bf42008-08-08 22:52:51 +00004348- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4349 upon first access it can be automatically initialized from the csv file if
4350 it wasn't initialized during instantiation.
4351
Brett Cannon3aa2a492008-08-06 22:28:09 +00004352- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4353 the reload() built-in has been removed.
4354
Brett Cannon7e30b672008-08-04 21:52:25 +00004355- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004356 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4364 raised an AttributeError.
4365
Benjamin Peterson01a24322008-07-28 23:35:27 +00004366- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004367 asking for a specific length. This problem only affected files opened
4368 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004369

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004393- Issue #3394: zipfile.writestr sets external attributes when passed a
4394 file name rather than a ZipInfo instance, so files are extracted with
4395 mode 0600 rather than 000 under Unix.
4396
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004397- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4398 argument in python 2.5, this broke code that subclassed Popen to include its
4399 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004409- Issue #2235: the C API function PyObject_HashNotImplemented and its
4410 interaction with the tp_hash slot (added in 2.6b2) are now documented
4411
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004412- Issue #643841: The language reference now provides more detailed
4413 coverage of the lookup process for special methods. The disclaimers
4414 regarding lack of coverage of new-style classes have also been
4415 removed, since the coverage is now fairly reasonable.

4419================================
4420
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004421*Release date: 17-Jul-2008*
4422
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004423Core and Builtins
4424-----------------
4425
Georg Brandl3e483f62008-07-16 22:57:41 +00004426- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4427 its methods now allow for items objects that can be converted to
4428 an integer using operator.index().
4429
Mark Dickinson64b7e502008-07-16 09:40:03 +00004430- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4431 produced a ValueError instead of giving the correct float.
4432
Eric Smitha5fa5a22008-07-16 00:11:49 +00004433- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4434 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4435
Mark Dickinson7103aa42008-07-15 19:08:33 +00004436- Issue #3008: the float type has a new instance method 'float.hex'
4437 and a new class method 'float.fromhex' to convert floating-point
4438 numbers to and from hexadecimal strings, respectively.
4439
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004440- Issue #2235: __hash__ is once again inherited by default. To allow
4441 collections.Hashable to remain meaningful in the presence of the
4442 default hash implementation (object.__hash__), it is now possible
4443 to explicit block inheritance of hash by setting __hash__=None at
4444 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4445 level.
4446
Nick Coghlanb028f502008-07-13 14:52:36 +00004447- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4448 the parent module cannot be found while performing an absolute import.
4449 This means that an incorrectly defined __package__ attribute will
4450 now only prevent relative imports in that module rather than causing
4451 all imports from that module to fail.
4452
Nick Coghlan14ff9942008-07-08 14:21:42 +00004453- Issue #2517: Allow unicode messages in Exceptions again by correctly
4454 bypassing the instance dictionary when looking up __unicode__ on
4455 new-style classes.
4456
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004457- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4458 set to a custom object whose write() method happens to install
4459 another file in sys.stdout.
4460
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004461- Issue #3088: Corrected a race condition in classes derived from
4462 threading.local: the first member set by a thread could be saved in
4463 another thread's dictionary.
4464
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004465- Issue #3004: Minor change to slice.indices(): the start and stop
4466 arguments are now treated identically, making the behaviour easier
4467 to describe and understand. For example, slice(None, -10,
4468 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4469 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4470 10, -1).
4471
Georg Brandl278fc502008-07-19 12:46:12 +00004472- Issue #3219: Calling a function with repeated keyword arguments,
4473 f(a=2, a=23), would not cause a syntax error. This was a regression
4474 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004475
Georg Brandl278fc502008-07-19 12:46:12 +00004476- Issue #2862: Make int and float freelist management consistent with
4477 other freelists. Changes their CompactFreeList apis into
4478 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004479

4481-------
4482
Thomas Heller57adf222008-08-14 19:10:48 +00004483- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4484 api functions without holding the GIL, which could lead to a fatal
4485 error when they failed.
4486
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004487- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004495- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4496 ForkingPickler.register() to resolve conflict with ctypes.
4497
Vinay Sajip51e65192008-07-18 09:01:10 +00004498- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004499
Thomas Heller880f5292008-07-15 19:39:38 +00004500- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4501 a valid dlerror() message.
4502
Thomas Heller2bad6572008-07-15 17:19:50 +00004503- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4504 incomplete structure was created.
4505
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004506- Issue #3339: dummy_thread.acquire() should not return None.
4507
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004508- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4509
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004510- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004511
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004512- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4513 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004514 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004515 content-length. The problem had been corrected in the 2.4 branch, but never
4516 merged into trunk.
4517
Georg Brandle78fbcc2008-07-05 10:13:36 +00004518- Issue #2663: add filtering capability to shutil.copytree().

4524- Issue #1746: Correct handling of zipfile archive comments (previously
4525 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004526 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004527
Vinay Sajip51e65192008-07-18 09:01:10 +00004528- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004529 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004530
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004531- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4532 handling is now the same as that of other special attributes like __name__).
4533
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004534- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4535 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004924 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004925
4926 This is controlled by the configure argument ``--with-universal-archs``:
4927
4928 - ``--with-universal-archs=all``: install 4-way universal
4929
4930 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4931
4932 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4933
4934 This option should be used in combination with ``--enable-universalsdk=``.
4935
4936 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 +00004986- Issue #1631171: Re-implement the 'warnings' module in C (the
4987 original Python code has been kept as backup). This will allow for
4988 using the 'warning's machinery in such places as the parser where
4989 use of pure Python code is not possible. Both the ``showarning()``
4990 and ``formatwarning()`` gain an optional 'line' argument which is
4991 not called by default for backwards-compatibility reasons. Setting
4992 ``warnings.showwarning()`` to an implementation that lacks support
4993 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005056- Issue #2550: The approach used by client/server code for obtaining
5057 ports to listen on in network-oriented tests has been refined in an
5058 effort to facilitate running multiple instances of the entire
5059 regression test suite in parallel without issue.
5060 test_support.bind_port() has been fixed such that it will always
5061 return a unique port -- which wasn't always the case with the
5062 previous implementation, especially if socket options had been set
5063 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5064 new implementation of bind_port() will actually raise an exception
5065 if it is passed an AF_INET/SOCK_STREAM socket with either the
5066 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5067 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5068 the socket it's been passed. This currently only applies to
5069 Windows. This option prevents any other sockets from binding to the
5070 host/port we've bound to, thus removing the possibility of the
5071 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5072 when a second SOCK_STREAM socket binds and accepts to a host/port
5073 that's already been bound by another socket. The optional preferred
5074 port parameter to bind_port() has been removed. Under no
5075 circumstances should tests be hard coding ports!
5076
5077 test_support.find_unused_port() has also been introduced, which will
5078 pass a temporary socket object to bind_port() in order to obtain an
5079 unused port. The temporary socket object is then closed and
5080 deleted, and the port is returned. This method should only be used
5081 for obtaining an unused port in order to pass to an external program
5082 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5083 a parameter to a server-oriented class that doesn't give you direct
5084 access to the underlying socket used.
5085
5086 Finally, test_support.HOST has been introduced, which should be used
5087 for the host argument of any relevant socket calls (i.e. bind and
5088 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005089
5090 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005091 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005092 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5093 test_asynchat and test_socket_ssl.
5094
Georg Brandl3ee81df2008-05-17 18:14:43 +00005095 It is now possible for multiple instances of the regression test
5096 suite to run in parallel without issue.

5362Core and builtins
5363-----------------
5364
Fred Drakea8ee94b2008-03-01 02:45:07 +00005365- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005366 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005367
Georg Brandlad61bc82008-02-23 15:11:18 +00005368- Issue #2067: file.__exit__() now calls subclasses' close() method.
5369
5370- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005371
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005372- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005373 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005374
Eric Smitha73fbe72008-02-23 03:09:44 +00005375- Added the future_builtins module, which contains hex() and oct().
5376 These are the PEP 3127 version of these functions, designed to be
5377 compatible with the hex() and oct() builtins from Python 3.0. They
5378 differ slightly in their output formats from the existing, unchanged
5379 Python 2.6 builtins. The expected usage of the future_builtins
5380 module is:
5381 from future_builtins import hex, oct
5382
Eric Smith7ef40bf2008-02-20 23:34:22 +00005383- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5384 exponents for exponents with absolute value < 100. Follows C99
5385 standard. This is a change on Windows, which would use 3 digits.
5386 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5387 so that any alterations it does to the resulting string will be
5388 available in stringlib/formatter.h (for float.__format__).
5389
Eric Smith5a3c1352008-02-19 13:21:56 +00005390- Implemented PEP 3101, Advanced String Formatting. This adds a new
5391 builtin format(); a format() method for str and unicode; a
5392 __format__() method to object, str, unicode, int, long, float, and
5393 datetime; the class string.Formatter; and the C API
5394 PyObject_Format().
5395
Georg Brandl3ee81df2008-05-17 18:14:43 +00005396- Fixed several potential crashes, all caused by specially crafted
5397 __del__ methods exploiting objects in temporarily inconsistent
5398 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005399
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005400- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005401 prevent a possible crash: an Abstract Base Class would try to access
5402 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005403
Georg Brandl3ee81df2008-05-17 18:14:43 +00005404- Fixed repr() and str() of complex numbers with infinity or nan as
5405 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005406
Georg Brandl3ee81df2008-05-17 18:14:43 +00005407- Clear all free lists during a gc.collect() of the highest generation
5408 in order to allow pymalloc to free more arenas. Python may give back
5409 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005410
Georg Brandl3ee81df2008-05-17 18:14:43 +00005411- Issue #2045: Fix an infinite recursion triggered when printing a
5412 subclass of collections.defaultdict, if its default_factory is set
5413 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005414
Christian Heimesf75dbef2008-02-08 00:11:31 +00005415- Fixed a minor memory leak in dictobject.c. The content of the free
5416 list was not freed on interpreter shutdown.
5417
Georg Brandl21e99f42010-03-07 15:23:59 +00005418- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005419 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005420
Georg Brandl3ee81df2008-05-17 18:14:43 +00005421- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5422 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005423 to compact the internal free lists of pre-allocted ints and floats.
5424
Georg Brandl3ee81df2008-05-17 18:14:43 +00005425- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5426 calls. Python expected the return type int but the fork familie
5427 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005428
Georg Brandl3ee81df2008-05-17 18:14:43 +00005429- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5430 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005431
Georg Brandl3ee81df2008-05-17 18:14:43 +00005432- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5433 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005434
Georg Brandl3ee81df2008-05-17 18:14:43 +00005435- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5436 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005437
Georg Brandl3ee81df2008-05-17 18:14:43 +00005438- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5439 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005440
Georg Brandl3ee81df2008-05-17 18:14:43 +00005441- Patch #1473257: generator objects gain a gi_code attribute. This is
5442 the same object as the func_code attribute of the function that
5443 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005444
Georg Brandl3ee81df2008-05-17 18:14:43 +00005445- Issue #1920: "while 0" statements were completely removed by the
5446 compiler, even in the presence of an "else" clause, which is
5447 supposed to be run when the condition is false. Now the compiler
5448 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005449
Guido van Rossumeead05f2008-01-24 18:21:02 +00005450- A few crashers fixed: weakref_in_del.py (issue #1377858);
5451 loosing_dict_ref.py (issue #1303614, test67.py);
5452 borrowed_ref_[34].py (not in tracker).
5453
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005454- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005455 suppressed while an extension is loaded by calling SetErrorMode in
5456 dynload_win.c. The error is still reported properly.
5457
Georg Brandl3ee81df2008-05-17 18:14:43 +00005458- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005459 several extension methods and modules do not work without unicode
5460 support.
5461
Georg Brandl26543b12008-01-21 18:36:51 +00005462- Issue #1882: when compiling code from a string, encoding cookies in the
5463 second line of code were not always recognized correctly.
5464
Georg Brandl14404b62008-01-19 19:27:05 +00005465- Issue #1679: "0x" was taken as a valid integer literal.
5466
Georg Brandl6caad7d2008-01-26 14:19:22 +00005467- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005468 added.
5469
Christian Heimesc94e2b52008-01-14 04:13:37 +00005470- sys.float_info / PyFloat_GetInfo: The floating point information
5471 object was converted from a dict to a specialized structseq object.
5472
Georg Brandl3ee81df2008-05-17 18:14:43 +00005473- Patch #1816: Added sys.flags structseq. It exposes the status of
5474 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005475
Georg Brandl3ee81df2008-05-17 18:14:43 +00005476- Objects/structseq.c: Implemented new structseq representation. The
5477 patch makes structseqs (e.g. the return value of os.stat) more
5478 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005479
Georg Brandl3ee81df2008-05-17 18:14:43 +00005480- Patch #1700288: added a type attribute cache that caches method
5481 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005482
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005483- Bug #1776: __import__() no longer accepts filenames on any platform.
5484 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005485
Georg Brandlaed6c662008-01-07 17:25:53 +00005486- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5487
Georg Brandl3ee81df2008-05-17 18:14:43 +00005488- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5489 envvar and sys.dont_write_bytecode attribute. All these can be set
5490 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005491
Georg Brandl3ee81df2008-05-17 18:14:43 +00005492- Improve some exception messages when Windows fails to load an
5493 extension module. Now we get for example '%1 is not a valid Win32
5494 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005495
Georg Brandl3ee81df2008-05-17 18:14:43 +00005496- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005498- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5499 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005500
Christian Heimes0a8143f2007-12-18 23:22:54 +00005501- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005502 and INF. float("nan"), float("inf") and float("-inf") now work on
5503 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005504
Georg Brandl3ee81df2008-05-17 18:14:43 +00005505- Compiler now generates simpler and faster code for dictionary
5506 literals. The oparg for BUILD_MAP now indicates an estimated
5507 dictionary size. There is a new opcode, STORE_MAP, for adding
5508 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005509
Georg Brandl3ee81df2008-05-17 18:14:43 +00005510- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005515- Issue #1538: Avoid copying string in split/rsplit if the split char
5516 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005517
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005518- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005519 SystemError.
5520
Nick Coghlanef01d822007-12-03 12:55:17 +00005521- PEP 366: Allow explicit relative imports when executing modules
5522 inside packages with the -m switch via a new module level
5523 __package__ attribute.
5524
Georg Brandl3ee81df2008-05-17 18:14:43 +00005525- Issue #1402: Fix a crash on exit, when another thread is still
5526 running, and if the deallocation of its frames somehow calls the
5527 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005528

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005532 attribute of an empty cell object.
5533
Georg Brandl3ee81df2008-05-17 18:14:43 +00005534- Issue #1460: The utf-7 incremental decoder did not accept truncated
5535 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005536
Georg Brandl3ee81df2008-05-17 18:14:43 +00005537- Patch #1739468: Directories and zipfiles containing a __main__.py
5538 file can now be directly executed by passing their name to the
5539 interpreter. The directory/zipfile is automatically inserted as the
5540 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005541
Georg Brandl3ee81df2008-05-17 18:14:43 +00005542- Issue #1265: Fix a problem with sys.settrace, if the tracing
5543 function uses a generator expression when at the same time the
5544 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005545
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005546- sets and frozensets now have an isdisjoint() method.
5547
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005548- optimize the performance of builtin.sum().
5549
Neal Norwitz44f326e2007-10-05 05:29:17 +00005550- Fix warnings found by the new version of the Coverity checker.
5551
Georg Brandl21e99f42010-03-07 15:23:59 +00005552- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005553 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5554 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005555
Georg Brandl3ee81df2008-05-17 18:14:43 +00005556- Issue #1686386: Tuple's tp_repr did not take into account the
5557 possibility of having a self-referential tuple, which is possible
5558 from C code. Nor did object's tp_str consider that a type's tp_str
5559 could do something that could lead to an inifinite recursion.
5560 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5561 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005562
Georg Brandl3ee81df2008-05-17 18:14:43 +00005563- Issue #1164: It was possible to trigger deadlock when using the
5564 'print' statement to write to a file since the GIL was not released
5565 as needed. Now PyObject_Print() does the right thing along with
5566 various tp_print implementations of the built-in types and those in
5567 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005568
Georg Brandl3ee81df2008-05-17 18:14:43 +00005569- Issue #1147: Exceptions were directly allowing string exceptions in
5570 their throw() method even though string exceptions no longer
5571 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005572

Brett Cannon1e534b52007-09-07 04:18:30 +00005576- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005577 PyObject_Call() never calling back out to Python code to trigger
5578 recursion depth updates/checks. Required the creation of a static
5579 RuntimeError instance in case normalizing an exception put the
5580 recursion check value past its limit. Fixes crashers
5581 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005582
Georg Brandl3ee81df2008-05-17 18:14:43 +00005583- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005596- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005597 __*__ attributes. (Some already existed, e.g., __doc__ and
5598 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005599
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005600- Add -3 option to the interpreter to warn about features that are
5601 deprecated and will be changed/removed in Python 3.0.
5602

5604 calls.
5605
Collin Winter62903052007-05-18 23:11:24 +00005606- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005607 "except E as target:". This is to provide forwards compatibility
5608 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005609
Brett Cannon229cee22007-05-05 01:34:02 +00005610- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005612- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005613 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005615- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005616 setting a plain string, ie don't expand to single letter identifiers.
5617
Raymond Hettinger13936692007-04-11 18:40:58 +00005618- Request #1191699: Slices can now be pickled.

5628
Guido van Rossum143b5642007-03-23 04:58:42 +00005629- Bug #1683368: The object.__init__() and object.__new__() methods are
5630 now stricter in rejecting excess arguments. The only time when
5631 either allows excess arguments is when it is not overridden and the
5632 other one is. For backwards compatibility, when both are
5633 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005634 warning later). Also, type.__init__() insists on the same signature
5635 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005636
Georg Brandl3ee81df2008-05-17 18:14:43 +00005637- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5638 object to complex using its __complex__() method before falling back
5639 to the __float__() method. Therefore, the functions in the cmath
5640 module now can operate on objects that define a __complex__()
5641 method.

5658
Georg Brandl7b9c5552007-03-12 14:30:05 +00005659- Bug #1678647: write a newline after printing an exception in any
5660 case, even when converting the value to a string failed.
5661
Georg Brandl871f1bc2007-03-12 13:17:36 +00005662- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005663 its argument, if it exists. If not, it will work like before. This
5664 allows customizing the output of dir() in the presence of a
5665 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005666
Collin Winter276887b2007-03-12 16:11:39 +00005667- Patch #922167: Python no longer segfaults when faced with infinitely
5668 self-recursive reload() calls (as reported by bug #742342).

5674 parthensized forms. This means complex(repr(x)) now works instead of
5675 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005676
Georg Brandlaa2321b2007-03-07 00:40:28 +00005677- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005678 makes the filenames the warning module prints much more sensible
5679 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005680

Georg Brandl0fca97a2007-03-05 22:28:08 +00005692- Patch #1674228: when assigning a slice (old-style), check for the
5693 sq_ass_slice instead of the sq_slice slot.
5694
Georg Brandl3ee81df2008-05-17 18:14:43 +00005695- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006230 AttributeError instead of an IOError when the server's response
6231 didn't contain a valid HTTP status line.

6322 TestCase and TestSuite subclasses (not instances) are no longer
6323 accepted in TestSuite.addTest(). This should cause no

6325 -- the failure just occurred later, with a more cumbersome

Georg Brandl3ee81df2008-05-17 18:14:43 +00006607- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6608 with RFC 3207 and forgets any knowledge obtained from the server not
6609 obtained from the TLS negotiation itself. Patch contributed by Bill
6610 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006611
Georg Brandl3ee81df2008-05-17 18:14:43 +00006612- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006613 that the SMTP.starttls() caller no longer needs to call ehlo()
6614 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006615 does not claim to support starttls. Adds the
6616 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6697 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6698 silently miscode subclasses of those types. Now, it raises a
6699 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006700

Georg Brandl3ee81df2008-05-17 18:14:43 +00006715 time so that opening a database previously created with the DB_DUP
6716 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6717 opens. Specifically: dictionary assignment to a DB object will
6718 replace all values for a given key when the database allows
6719 duplicate values. DB users should use DB.put(k, v) when they want
6720 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006721

6727 characters with ASCII value less than 32. Also, it correctly quotes
6728 dots only if they occur on a single line, as opposed to the previous
6729 behavior of quoting dots if they are the second character of any
6730 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006731

Georg Brandl3ee81df2008-05-17 18:14:43 +00007060- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7061 to ``PyTuple_SetItem``, it can be used to populate a brand new
7062 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007063
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007064- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007066- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7067 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7068 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007069
7070- Patch #1720595: add T_BOOL to the range of structmember types.
7071
7072- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7073 ``PyFloat_GetInfo()`` to the float API.
7074
Georg Brandl3ee81df2008-05-17 18:14:43 +00007075- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7076 of w# format code incorrectly truncated the length to an int, even
7077 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7078 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007079
Georg Brandl3ee81df2008-05-17 18:14:43 +00007080- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7081 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007082
Georg Brandl3ee81df2008-05-17 18:14:43 +00007083- PEP 3123: Provide forward compatibility with Python 3.0, while
7084 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7085 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007086
Georg Brandl3ee81df2008-05-17 18:14:43 +00007087- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7088 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007089
7090- Patch #1733960: Allow T_LONGLONG to accept ints.
7091
7092- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7093
Christian Heimes000a0742008-01-03 22:16:32 +00007094- Added a new API function ``PyImport_ImportModuleNoBlock``.
7095
Georg Brandl6caad7d2008-01-26 14:19:22 +00007096- Bug #1637022: Prefix AST symbols with _Py_.
7097
7098- Fix some leftovers from the conversion from int to Py_ssize_t
7099 (relevant to strings and sequences of more than 2**31 items).
7100
7101- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7102 outside of pystate.c and should not be necessary.
7103
Georg Brandl3ee81df2008-05-17 18:14:43 +00007104- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7105 absolute imports. In earlier versions they might have used relative
7106 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007107
Georg Brandl3ee81df2008-05-17 18:14:43 +00007108- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7109 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007110
Georg Brandl3ee81df2008-05-17 18:14:43 +00007111- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7112 macro so it can be used as an expression.

7117
Georg Brandl3ee81df2008-05-17 18:14:43 +00007118- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7119 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7120 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7121 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007122
Georg Brandl3ee81df2008-05-17 18:14:43 +00007123- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
7124 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00007134- buildtools now raises a DeprecationWarning.
7135
Georg Brandl3ee81df2008-05-17 18:14:43 +00007136- Removed the macfs module. It had been deprecated since Python 2.5.
7137 This lead to the deprecation of macostools.touched() as it relied
7138 solely on macfs and was a no-op under OS X.
