Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000301 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
302 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
303 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

323Core and Builtins
324-----------------
325
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000326- Issue #7301: Add environment variable $PYTHONWARNINGS.
327
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000328- Issue #8329: Don't return the same lists from select.select when no fds are
329 changed.
330
Georg Brandlfee0f442010-05-22 21:26:21 +0000331- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000332 on 64-bit machines. The shift count for either left or right shift is
333 permitted to be up to sys.maxsize.
334
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000335- Ensure that tokenization of identifiers is not affected by locale.
336
Georg Brandlfee0f442010-05-22 21:26:21 +0000337- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000338
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000339- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
340
Georg Brandlfee0f442010-05-22 21:26:21 +0000341- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
342 with a non-empty format string. This is an effort to future-proof user
343 code. If a derived class does not currently implement __format__ but later
344 adds its own __format__, it would most likely break user code that had
345 supplied a format string. This will be changed to a DeprecationWaring in
346 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000347
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000348- Issue #8268: Old-style classes (not just instances) now support weak
349 references.

372
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000373- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000374 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
375 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +0000377- Issue #8310: Allow dis to examine new style classes.
378
Georg Brandlfee0f442010-05-22 21:26:21 +0000379- Issue #8257: The Decimal construct now accepts a float instance directly,
380 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000381
382 >>> Decimal(1.1)
383 Decimal('1.100000000000000088817841970012523233890533447265625')
384
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000385- collections.Counter() now supports a subtract() method.
386
Georg Brandlfee0f442010-05-22 21:26:21 +0000387- The functools module now has a total_ordering() class decorator to simplify
388 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000389
Georg Brandlfee0f442010-05-22 21:26:21 +0000390- The functools module also adds cmp_to_key() as a tool to transition old-style
391 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000392
Georg Brandlfee0f442010-05-22 21:26:21 +0000393- Issue #8294: The Fraction constructor now accepts Decimal and float instances
394 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000395
Georg Brandlfee0f442010-05-22 21:26:21 +0000396- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
397 InvalidOperation instead of returning False. (Comparisons involving a quiet
398 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
399 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000400
Georg Brandlfee0f442010-05-22 21:26:21 +0000401- Issue #2531: Comparison operations between floats and Decimal instances now
402 return a result based on the numeric values of the operands; previously they
403 returned an arbitrary result based on the relative ordering of id(float) and
404 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000405
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000406- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000407 argument `-` which tells it to read files to compile from stdin. Each line is
408 read on demand and the named file is compiled immediately. (Original patch by
409 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000410
Georg Brandlfee0f442010-05-22 21:26:21 +0000411- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000414- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
415 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000416 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000417
Georg Brandlfee0f442010-05-22 21:26:21 +0000418- Comparisons using one of <, <=, >, >= between a complex instance and a
419 Fractions instance now raise TypeError instead of returning True/False. This
420 makes Fraction <=> complex comparisons consistent with int <=> complex, float
421 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000422
Michael Foorde6410c52010-03-29 20:04:23 +0000423- Addition of ``WeakSet`` to the ``weakref`` module.

431
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000432- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000433 didn't support chflags() (for example ZFS under FreeBSD). The error is now
434 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000435
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000436- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000476- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000477 for ``TimedRotatingFileHandler`` by using the modification time of an existing
478 log file to compute the next rollover time. If the log file does not exist,
479 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000480

Georg Brandlba83f822010-03-14 09:50:54 +0000525- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
526 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +0000528 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
529 inconsistent: __int__ was used for some integer codes but not for others, and
530 the set of integer codes for which it was used differed between native packing
531 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000736- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
737 now also used by regrtest to run all the tests in a temporary directory. The
738 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
739 Xicluna who helped with the patch.

756 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000757 library would return a bogus result; on Solaris, it was possible to crash the
758 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000771- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
772 and add the additional members returned in an OSVERSIONINFOEX structure. The
773 new members are service_pack_major, service_pack_minor, suite_mask, and
774 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000776- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
777 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
778 returning NULL. The macro now returns a statically allocated empty string
779 instead.

789 strings,
790 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
791 numeric strings corresponding to subnormal values,
792 (3) a memory leak for some values large enough to cause overflow, and
793 (4) a number of flaws that could lead to incorrectly rounded results.
794

808 interpreter shutdown.
809
Georg Brandlba83f822010-03-14 09:50:54 +0000810- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
811 XML processing instructions and comments. These raw characters are allowed
812 by the XML specification, and are necessary when outputting e.g. PHP code in
813 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +0000821- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000822 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000823 Also, raise ValueError rather than TypeError when an unknown TIPC address
824 type is specified. Patch by Brian Curtin.
825
Vinay Sajip28c382f2010-02-04 18:48:53 +0000826- logging: Implemented PEP 391.
827
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000828- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000829 file position when calling `truncate()`. It would previously change the file
830 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000831 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
832
Benjamin Petersone06f7112010-01-28 02:15:02 +0000833- UserDict is now a new-style class.
834
Georg Brandlba83f822010-03-14 09:50:54 +0000835- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
836 class used to represent files stored inside an archive. The new
837 implementation is significantly faster and can be wrapped in a
838 ``io.BufferedReader`` object for more speedups. It also solves an issue
839 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
840 Patch by Nir Aides.

848 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000849
Georg Brandlba83f822010-03-14 09:50:54 +0000850- Issue #7748: Since unicode values are supported for some metadata options in
851 Distutils, the DistributionMetadata get_* methods will now return an utf-8
852 encoded string for them. This ensures that the upload and register commands
853 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000855- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000856 headers in multipart/signed MIME parts, which fixes one of the sources of

927Core and Builtins
928-----------------
929
Georg Brandlba83f822010-03-14 09:50:54 +0000930- The ``__complex__()`` method is now looked up on the class of instances to
931 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000932
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000933- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
934 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
935
Mark Dickinson1b34d252010-01-01 17:27:30 +0000936- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000937 DeprecationWarning when passed a float argument where an integer was expected.
938 These functions and methods now raise TypeError instead. The majority of the
939 effects of this change are in the extension modules, but some core functions
940 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
941 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000954- Issue #1811: Improve accuracy and cross-platform consistency for true division
955 of integers: the result of a/b is now correctly rounded for ints a and b (at
956 least on IEEE 754 platforms), and in particular does not depend on the
957 internal representation of a long.

965
Georg Brandlba83f822010-03-14 09:50:54 +0000966 These executables now work properly with the arch(1) command: ``arch -ppc
967 python`` will start a universal binary version of python in PPC mode (unlike
968 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000969

1108 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001109
Georg Brandlba83f822010-03-14 09:50:54 +00001110- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1111 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001112

Georg Brandlba83f822010-03-14 09:50:54 +00001124- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1125 decimal string that's guaranteed to round back to x under correct rounding
1126 (with round-half-to-even rounding mode). Previously it gave a string based on
1127 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1128 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1129 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001130
Georg Brandlba83f822010-03-14 09:50:54 +00001131- Issue #7117: On almost all platforms: float-to-string and string-to-float
1132 conversions within Python are now correctly rounded. Places these conversions
1133 occur include: str for floats and complex numbers; the float and complex
1134 constructors; old-style and new-style numeric formatting; serialization and
1135 deserialization of floats and complex numbers using marshal, pickle and json;
1136 parsing of float and imaginary literals in Python code; Decimal-to-float
1137 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001138
Georg Brandlba83f822010-03-14 09:50:54 +00001139 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1140 providing correctly-rounded strtod and dtoa C functions. This code is
1141 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1142 the C compiler. There may be a small number of platforms on which correct
1143 operation of this code cannot be guaranteed, so the code is not used: notably,
1144 this applies to platforms where the C double format is not IEEE 754 binary64,
1145 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1146 and Python's configure script is unable to determine how to change the FPU
1147 precision. On these platforms conversions use the platform strtod and dtoa,
1148 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001150- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1151 uses the correctly-rounded string <-> float conversions described above (when
1152 available), and so produces correctly rounded results that will display nicely
1153 under the float repr. There are two related small changes: (1) round now
1154 accepts any class with an ``__index__()`` method for its second argument (but
1155 no longer accepts floats for the second argument), and (2) an excessively
1156 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1157 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001304- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1305 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1306 but with at least one decimal point and with a default precision
1307 of 12. Previously, the behavior the same but with a default precision of 6.
1308 This more closely matches ``str()``, and reduces surprises when adding
1309 alignment flags to the empty presentation type. This also affects the new
1310 complex.__format__ in the same way.

1449
Georg Brandlba83f822010-03-14 09:50:54 +00001450- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1451 existing .py counterpart, override the co_filename attributes of all code
1452 objects if the original filename is obsolete (which can happen if the file has
1453 been renamed, moved, or if it is accessed through different paths). Patch by
1454 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00001455

Martin v. Löwis5344c992009-01-02 20:32:55 +00001457
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00001458- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
1459 file with `str' filename on Windows.
1460
Antoine Pitrouaa687902009-01-01 14:11:22 +00001461- Issue #3680: Reference cycles created through a dict, set or deque iterator
1462 did not get collected.
1463
Georg Brandlba83f822010-03-14 09:50:54 +00001464- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
1465 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00001466
Benjamin Peterson7af65562008-12-29 17:56:58 +00001467- Issue #4764: With io.open, IOError.filename is set when trying to open a
1468 directory on POSIX systems.
1469
Benjamin Petersonfe231b02008-12-29 17:47:42 +00001470- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1471 systems.
1472
Georg Brandl6425a2f2008-12-28 11:54:53 +00001473- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001474 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001475
Skip Montanarof205c132008-12-23 03:30:15 +00001476- Added test case to ensure attempts to read from a file opened for writing
1477 fail.
1478
Georg Brandlba83f822010-03-14 09:50:54 +00001479- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1480 elapsed times, not only when some objects are uncollectable/unreachable.
1481 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00001482
Mark Dickinson1a707982008-12-17 16:14:37 +00001483- Issue #3439: Add a bit_length method to int and long.
1484
Georg Brandlba83f822010-03-14 09:50:54 +00001485- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
1486 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00001487
Georg Brandlba83f822010-03-14 09:50:54 +00001488- Issue #4597: Fixed exception handling when the __exit__ function of a context
1489 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00001490
Georg Brandlba83f822010-03-14 09:50:54 +00001491- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00001492
Georg Brandlba83f822010-03-14 09:50:54 +00001493- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1494 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1495 instances. On a typical machine this saves 3 bytes of memory (on average) per
1496 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001497
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001498- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1499 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1500 instead of throwing a MemoryError.
1501
Georg Brandlba83f822010-03-14 09:50:54 +00001502- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1503 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001504
Benjamin Petersonc078f922008-11-21 22:27:24 +00001505- Issue #4367: Python would segfault during compiling when the unicodedata
1506 module couldn't be imported and \N escapes were present.
1507
Georg Brandlba83f822010-03-14 09:50:54 +00001508- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1509 file objects with closefd=False. The file descriptor is still kept open but
1510 the file object behaves like a closed file. The ``FileIO`` object also got a
1511 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001512
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001513- Issue #4348: Some bytearray methods returned that didn't cause any change to
1514 the bytearray, returned the same bytearray instead of a copy.
1515
Georg Brandlba83f822010-03-14 09:50:54 +00001516- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00001518- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1519
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001520- Issue #4048: The parser module now correctly validates relative imports.
1521
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001522- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1523 exec statement.
1524
Georg Brandlba83f822010-03-14 09:50:54 +00001525- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
1526 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001527
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001528- Issue #4209: Enabling unicode_literals and the print_function in the same
1529 __future__ import didn't work.
1530
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001531- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001532 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001533
Georg Brandlba83f822010-03-14 09:50:54 +00001534- On windows, ``os.chdir()`` given unicode was not working if
1535 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1536 this code path is really executed because I cannot move to such directory on
1537 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001538
Georg Brandlba83f822010-03-14 09:50:54 +00001539- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1540 element is temporarily replaced with an equivalent frozenset. But the
1541 eventual KeyError would always report the empty ``frozenset()`` as the missing
1542 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00001543
Georg Brandlba83f822010-03-14 09:50:54 +00001544- Issue #4509: Various issues surrounding resize of bytearray objects to which
1545 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00001546
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00001547- Issue #4748: Lambda generators no longer return a value.
1548

1550
Gregory P. Smithae91d092009-03-02 05:13:57 +00001551- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
1552
Georg Brandlba83f822010-03-14 09:50:54 +00001553- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
1554 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00001555
Matthias Klose91a3b9e2009-04-05 21:19:13 +00001556- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1557 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00001558
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001559- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1560 returned them on 64bit platforms.
1561
Walter Dörwalded960ac2009-05-03 22:36:33 +00001562- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1563 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1564 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1565 of using the replace error handler in PyUnicode_DecodeUTF8().
1566
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001567- Issue #3739: The unicode-internal encoder now reports the number of characters
1568 consumed like any other encoder (instead of the number of bytes).
1569
Georg Brandlba83f822010-03-14 09:50:54 +00001570- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1571 allocator will be automatically disabled when running under Valgrind. This
1572 gives improved memory leak detection when running under Valgrind, while taking
1573 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00001598- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
1599 ownership when the group is not forced, because the group may be different
1600 from the user's group and inherit from its container when the test is run.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002815- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2816 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002817 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2818 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00002823- Issue #5354: New test support function import_fresh_module() makes it easy to
2824 import both normal and optimised versions of modules. test_heapq and
2825 test_warnings have been adjusted to use it, tests for other modules with both
2826 C and Python implementations in the stdlib can be adjusted to use it over
2827 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002835- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2836 should cause a test to be skipped are now done using import_module from test
2837 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002938- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2939
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002940- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2941 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2942 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2943 ``printf`` function, whereas PyString_FromFormat has an independent
2944 implementation and uses "%zd" on all platforms for size_t values.
2945 This makes a difference on win64, where ``printf`` needs "%Id" to display
2946 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002948- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2952 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002963 was correctly parsed but parsing of subsequent arguments failed.
2964
Vinay Sajip35e3b032008-09-01 14:33:59 +00002965- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002966 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2967 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2968 when given a tuple of classes as second argument, were looking up
2969 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2970 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003109What's New in Python 2.6 beta 3?
3110================================
3111
Barry Warsaw07a4a382008-08-21 01:15:08 +00003112*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003113
3114Core and Builtins
3115-----------------
3116
Guido van Rossumf8402962008-08-20 15:01:50 +00003117- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3118 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3119 extensions do not automatically benefit from the class attribute
3120 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3121 to their tp_flags field if they care. This is a backwards
3122 compatibility feature; in 3.0, all types will use the cache by
3123 default.
3124
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003125- Keyword arguments can now follow starred arguments. (``f(a, *args,
3126 keyword=23)`` is now valid syntax.)
3127
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003128- ctypes function pointers that are COM methods have a boolean True
3129 value again.
3130
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003131- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3132 by denying s# to parse objects that have a releasebuffer procedure,
3133 and introducing s*.
3134
Georg Brandl1e13ea92008-08-11 09:07:59 +00003135- Issue #3537: Fix an assertion failure when an empty but presized dict
3136 object was stored in the freelist.
3137
Mark Dickinsonb6467572008-08-04 21:30:09 +00003138- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3139 ValueError consistently across platforms.
3140
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003141- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3142 (64bit Unix, for example), unichr() would truncate its argument and return
3143 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3144
Neal Norwitze7d8be82008-07-31 17:17:14 +00003145- Apply security patches from Apple.
3146
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003147- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3148 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3149
Antoine Pitrou92f82162008-07-25 22:22:08 +00003150- Issue #1819: function calls with several named parameters are now on
3151 average 35% faster (as measured by pybench).
3152
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003153- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3154 the python debugger steps into a class statement: the free variables (local
3155 variables defined in an outer scope) would be deleted from the outer scope.
3156
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003157- Issue #2620: Overflow checking when allocating or reallocating memory
3158 was not always being done properly in some python types and extension
3159 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3160 all been updated to perform better checks and places in the code that
3161 would previously leak memory on the error path when such an allocation
3162 failed have been fixed.
3163
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003164Library
3165-------
3166
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003167- Issue #3612: Added some missing basic types in ctypes.wintypes.
3168
Benjamin Petersone977ad42008-08-20 01:42:01 +00003169- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3170 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3171
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003172- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3173 version reported by these tools does not necessarily follow the python
3174 version numbering scheme, so the module is less strict when parsing it.
3175
Nick Coghlanf70385a2008-08-18 12:42:46 +00003176- Issue #2235: Added Py3k warnings for types which will become unhashable
3177 under the stricter __hash__ inheritance rules in 3.0. Several types
3178 which did not meet the rules for hash invariants and were already
3179 unhashable in 3.0 have now been explicitly flagged as unhashable in
3180 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3181 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3182
Brett Cannon88f801d2008-08-18 00:46:22 +00003183- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3184 imported into the module but exposed as part of the module's API.
3185
Brett Cannon7b96f072008-08-18 00:41:11 +00003186- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3187
Brett Cannon46225e72008-08-18 00:36:52 +00003188- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3189
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003190- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3191
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003192- Issue #3575: Incremental decoder's decode function now takes bytearray
3193 by using 's*' instead of 't#'.
3194
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003195- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003196 fails unicode conversion on 2nd parameter. (windows only)
3197
Facundo Batista94f243a2008-08-17 03:38:39 +00003198- Issue 2464. urllib2 now supports a malformation in the URL received
3199 in a redirect.
3200
Brett Cannonabe423e2008-08-16 21:47:07 +00003201- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003202 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003203
Facundo Batistaeb90b782008-08-16 14:44:07 +00003204- Issue #2776: fixed small issue when handling an URL with double slash
3205 after a 302 response in the case of not going through a proxy.
3206
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003207- Issue #2676: in the email package, content-type parsing was hanging on
3208 pathological input because of quadratic or exponential behaviour of a
3209 regular expression.
3210
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003211- Issue #3476: binary buffered reading through the new "io" library is now
3212 thread-safe.
3213
Brett Cannonbf3157b2008-08-14 05:00:03 +00003214- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3215 since mimetools itself is deprecated. Because modules are cached, all
3216 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3217
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003218- Issue #3134: shutil referenced undefined WindowsError symbol.
3219
Robert Schuppenies14646332008-08-10 11:01:53 +00003220- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3221 menu entries were not deleted.
3222
Brett Cannon83e81842008-08-09 23:30:55 +00003223- Copied the implementation of reduce() to _functools.reduce() to have a
3224 version that did not raise a DeprecationWarning under -3.
3225
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003226- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3227 a MemoryError rather than silently stop the iteration.
3228
Guido van Rossum59ce9012008-08-09 14:55:34 +00003229- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3230 to _sre.compile() will now be rejected. This should not affect anybody
3231 since the re.compile() function never generates invalid re-bytecode.
3232
Skip Montanaroa032bf42008-08-08 22:52:51 +00003233- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3234 upon first access it can be automatically initialized from the csv file if
3235 it wasn't initialized during instantiation.
3236
Brett Cannon3aa2a492008-08-06 22:28:09 +00003237- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3238 the reload() built-in has been removed.
3239
Brett Cannon7e30b672008-08-04 21:52:25 +00003240- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003241 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003242 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3243 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3244 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3245 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3246 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003247
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003248- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3249 raised an AttributeError.
3250
Benjamin Peterson01a24322008-07-28 23:35:27 +00003251- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003252 asking for a specific length. This problem only affected files opened
3253 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003254
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003255- Issue #3449: Update decimal module to use most recent specification
3256 (v. 1.68) and tests (v. 2.58) from IBM.
3257
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003258- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3259
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003260- Issue 1592: Improve error reporting when operations are attempted
3261 on a closed shelf.

3264
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003265- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3266
3267- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3268 invalid arguments.
3269
3270- Issue #3302: Fix several crashes when calling locale's gettext functions
3271 with None arguments.
3272
3273- Issue #3389: Allow resolving dotted names for handlers in logging
3274 configuration files.
3275
3276- Deprecate the sunaudio module for removal in Python 3.0.
3277
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003278- Issue #3394: zipfile.writestr sets external attributes when passed a
3279 file name rather than a ZipInfo instance, so files are extracted with
3280 mode 0600 rather than 000 under Unix.
3281
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003282- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3283 argument in python 2.5, this broke code that subclassed Popen to include its
3284 own poll method. Fixed my moving _deadstate to an _internal_poll method.
3285
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00003286Build
3287-----

3292-------------
3293
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003294- Issue #2235: the C API function PyObject_HashNotImplemented and its
3295 interaction with the tp_hash slot (added in 2.6b2) are now documented
3296
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003297- Issue #643841: The language reference now provides more detailed
3298 coverage of the lookup process for special methods. The disclaimers
3299 regarding lack of coverage of new-style classes have also been
3300 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003303What's New in Python 2.6 beta 2?
3304================================
3305
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003306*Release date: 17-Jul-2008*
3307
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003308Core and Builtins
3309-----------------
3310
Georg Brandl3e483f62008-07-16 22:57:41 +00003311- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3312 its methods now allow for items objects that can be converted to
3313 an integer using operator.index().
3314
Mark Dickinson64b7e502008-07-16 09:40:03 +00003315- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3316 produced a ValueError instead of giving the correct float.
3317
Eric Smitha5fa5a22008-07-16 00:11:49 +00003318- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3319 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3320
Mark Dickinson7103aa42008-07-15 19:08:33 +00003321- Issue #3008: the float type has a new instance method 'float.hex'
3322 and a new class method 'float.fromhex' to convert floating-point
3323 numbers to and from hexadecimal strings, respectively.
3324
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003325- Issue #2235: __hash__ is once again inherited by default. To allow
3326 collections.Hashable to remain meaningful in the presence of the
3327 default hash implementation (object.__hash__), it is now possible
3328 to explicit block inheritance of hash by setting __hash__=None at
3329 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3330 level.
3331
Nick Coghlanb028f502008-07-13 14:52:36 +00003332- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3333 the parent module cannot be found while performing an absolute import.
3334 This means that an incorrectly defined __package__ attribute will
3335 now only prevent relative imports in that module rather than causing
3336 all imports from that module to fail.
3337
Nick Coghlan14ff9942008-07-08 14:21:42 +00003338- Issue #2517: Allow unicode messages in Exceptions again by correctly
3339 bypassing the instance dictionary when looking up __unicode__ on
3340 new-style classes.
3341
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003342- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3343 set to a custom object whose write() method happens to install
3344 another file in sys.stdout.
3345
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003346- Issue #3088: Corrected a race condition in classes derived from
3347 threading.local: the first member set by a thread could be saved in
3348 another thread's dictionary.
3349
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003350- Issue #3004: Minor change to slice.indices(): the start and stop
3351 arguments are now treated identically, making the behaviour easier
3352 to describe and understand. For example, slice(None, -10,
3353 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3354 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3355 10, -1).
3356
Georg Brandl278fc502008-07-19 12:46:12 +00003357- Issue #3219: Calling a function with repeated keyword arguments,
3358 f(a=2, a=23), would not cause a syntax error. This was a regression
3359 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003360
Georg Brandl278fc502008-07-19 12:46:12 +00003361- Issue #2862: Make int and float freelist management consistent with
3362 other freelists. Changes their CompactFreeList apis into
3363 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003364

3366-------
3367
Thomas Heller57adf222008-08-14 19:10:48 +00003368- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3369 api functions without holding the GIL, which could lead to a fatal
3370 error when they failed.
3371
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003372- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3379
Jesse Noller13e9d582008-07-16 14:32:36 +00003380- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3381 ForkingPickler.register() to resolve conflict with ctypes.
3382
Vinay Sajip51e65192008-07-18 09:01:10 +00003383- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003384
Thomas Heller880f5292008-07-15 19:39:38 +00003385- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3386 a valid dlerror() message.
3387
Thomas Heller2bad6572008-07-15 17:19:50 +00003388- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3389 incomplete structure was created.
3390
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003391- Issue #3339: dummy_thread.acquire() should not return None.
3392
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003393- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3394
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003395- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003396

3808 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003809 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003810
3811 This is controlled by the configure argument ``--with-universal-archs``:
3812
3813 - ``--with-universal-archs=all``: install 4-way universal
3814
3815 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3816
3817 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3818
3819 This option should be used in combination with ``--enable-universalsdk=``.
3820
3821 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3858 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00003859
Christian Heimese74c8f22008-04-19 02:23:57 +00003860- Added kill, terminate and send_signal(sig) to subprocess.Popen.
3861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
3863 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00003864

Georg Brandl3ee81df2008-05-17 18:14:43 +00003871- Issue #1631171: Re-implement the 'warnings' module in C (the
3872 original Python code has been kept as backup). This will allow for
3873 using the 'warning's machinery in such places as the parser where
3874 use of pure Python code is not possible. Both the ``showarning()``
3875 and ``formatwarning()`` gain an optional 'line' argument which is
3876 not called by default for backwards-compatibility reasons. Setting
3877 ``warnings.showwarning()`` to an implementation that lacks support
3878 for the ``line`` argument will raise a DeprecationWarning.

Neal Norwitz2b0bea52008-04-25 03:40:17 +00003900- Issue #2682: ctypes callback functions no longer contain a cyclic
Thomas Hellerbf027c42008-04-24 18:14:19 +00003901 reference to themselves.
3902
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003903- The getpass module has been improved on Unix. It now uses /dev/tty
3904 by default and uses stderr instead of stdout. A GetPassWarning is
3905 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003906

3917 implementation detail of the public ``types`` module, has been
3918 removed and replaced by pure python code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003920- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003921 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003941- Issue #2550: The approach used by client/server code for obtaining
3942 ports to listen on in network-oriented tests has been refined in an
3943 effort to facilitate running multiple instances of the entire
3944 regression test suite in parallel without issue.
3945 test_support.bind_port() has been fixed such that it will always
3946 return a unique port -- which wasn't always the case with the
3947 previous implementation, especially if socket options had been set
3948 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3949 new implementation of bind_port() will actually raise an exception
3950 if it is passed an AF_INET/SOCK_STREAM socket with either the
3951 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3952 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3953 the socket it's been passed. This currently only applies to
3954 Windows. This option prevents any other sockets from binding to the
3955 host/port we've bound to, thus removing the possibility of the
3956 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3957 when a second SOCK_STREAM socket binds and accepts to a host/port
3958 that's already been bound by another socket. The optional preferred
3959 port parameter to bind_port() has been removed. Under no
3960 circumstances should tests be hard coding ports!
3961
3962 test_support.find_unused_port() has also been introduced, which will
3963 pass a temporary socket object to bind_port() in order to obtain an
3964 unused port. The temporary socket object is then closed and
3965 deleted, and the port is returned. This method should only be used
3966 for obtaining an unused port in order to pass to an external program
3967 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3968 a parameter to a server-oriented class that doesn't give you direct
3969 access to the underlying socket used.
3970
3971 Finally, test_support.HOST has been introduced, which should be used
3972 for the host argument of any relevant socket calls (i.e. bind and
3973 connect).

4248-----------------
4249
Fred Drakea8ee94b2008-03-01 02:45:07 +00004250- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004251 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004252
Georg Brandlad61bc82008-02-23 15:11:18 +00004253- Issue #2067: file.__exit__() now calls subclasses' close() method.
4254
4255- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004256
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004257- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004258 issue 215555 for a discussion.
4259
Eric Smitha73fbe72008-02-23 03:09:44 +00004260- Added the future_builtins module, which contains hex() and oct().
4261 These are the PEP 3127 version of these functions, designed to be
4262 compatible with the hex() and oct() builtins from Python 3.0. They
4263 differ slightly in their output formats from the existing, unchanged
4264 Python 2.6 builtins. The expected usage of the future_builtins
4265 module is:
4266 from future_builtins import hex, oct
4267
Eric Smith7ef40bf2008-02-20 23:34:22 +00004268- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4269 exponents for exponents with absolute value < 100. Follows C99
4270 standard. This is a change on Windows, which would use 3 digits.
4271 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4272 so that any alterations it does to the resulting string will be
4273 available in stringlib/formatter.h (for float.__format__).
4274
Eric Smith5a3c1352008-02-19 13:21:56 +00004275- Implemented PEP 3101, Advanced String Formatting. This adds a new
4276 builtin format(); a format() method for str and unicode; a
4277 __format__() method to object, str, unicode, int, long, float, and
4278 datetime; the class string.Formatter; and the C API
4279 PyObject_Format().
4280
Georg Brandl3ee81df2008-05-17 18:14:43 +00004281- Fixed several potential crashes, all caused by specially crafted
4282 __del__ methods exploiting objects in temporarily inconsistent
4283 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004284
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004285- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004286 prevent a possible crash: an Abstract Base Class would try to access
4287 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004288
Georg Brandl3ee81df2008-05-17 18:14:43 +00004289- Fixed repr() and str() of complex numbers with infinity or nan as
4290 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004291
Georg Brandl3ee81df2008-05-17 18:14:43 +00004292- Clear all free lists during a gc.collect() of the highest generation
4293 in order to allow pymalloc to free more arenas. Python may give back
4294 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004295
Georg Brandl3ee81df2008-05-17 18:14:43 +00004296- Issue #2045: Fix an infinite recursion triggered when printing a
4297 subclass of collections.defaultdict, if its default_factory is set
4298 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004299
Christian Heimesf75dbef2008-02-08 00:11:31 +00004300- Fixed a minor memory leak in dictobject.c. The content of the free
4301 list was not freed on interpreter shutdown.
4302
Georg Brandl21e99f42010-03-07 15:23:59 +00004303- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004304 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004305
Georg Brandl3ee81df2008-05-17 18:14:43 +00004306- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4307 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004308 to compact the internal free lists of pre-allocted ints and floats.
4309
Georg Brandl3ee81df2008-05-17 18:14:43 +00004310- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4311 calls. Python expected the return type int but the fork familie
4312 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004313
Georg Brandl3ee81df2008-05-17 18:14:43 +00004314- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4315 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004316
Georg Brandl3ee81df2008-05-17 18:14:43 +00004317- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4318 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004319
Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4321 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004322
Georg Brandl3ee81df2008-05-17 18:14:43 +00004323- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4324 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004325
Georg Brandl3ee81df2008-05-17 18:14:43 +00004326- Patch #1473257: generator objects gain a gi_code attribute. This is
4327 the same object as the func_code attribute of the function that
4328 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004329
Georg Brandl3ee81df2008-05-17 18:14:43 +00004330- Issue #1920: "while 0" statements were completely removed by the
4331 compiler, even in the presence of an "else" clause, which is
4332 supposed to be run when the condition is false. Now the compiler
4333 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004334
Guido van Rossumeead05f2008-01-24 18:21:02 +00004335- A few crashers fixed: weakref_in_del.py (issue #1377858);
4336 loosing_dict_ref.py (issue #1303614, test67.py);
4337 borrowed_ref_[34].py (not in tracker).
4338
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004339- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004340 suppressed while an extension is loaded by calling SetErrorMode in
4341 dynload_win.c. The error is still reported properly.
4342
Georg Brandl3ee81df2008-05-17 18:14:43 +00004343- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004344 several extension methods and modules do not work without unicode
4345 support.
4346
Georg Brandl26543b12008-01-21 18:36:51 +00004347- Issue #1882: when compiling code from a string, encoding cookies in the
4348 second line of code were not always recognized correctly.
4349
Georg Brandl14404b62008-01-19 19:27:05 +00004350- Issue #1679: "0x" was taken as a valid integer literal.
4351
Georg Brandl6caad7d2008-01-26 14:19:22 +00004352- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004353 added.
4354
Christian Heimesc94e2b52008-01-14 04:13:37 +00004355- sys.float_info / PyFloat_GetInfo: The floating point information
4356 object was converted from a dict to a specialized structseq object.
4357
Georg Brandl3ee81df2008-05-17 18:14:43 +00004358- Patch #1816: Added sys.flags structseq. It exposes the status of
4359 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004360
Georg Brandl3ee81df2008-05-17 18:14:43 +00004361- Objects/structseq.c: Implemented new structseq representation. The
4362 patch makes structseqs (e.g. the return value of os.stat) more
4363 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004364
Georg Brandl3ee81df2008-05-17 18:14:43 +00004365- Patch #1700288: added a type attribute cache that caches method
4366 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004367
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004368- Bug #1776: __import__() no longer accepts filenames on any platform.
4369 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004370
Georg Brandlaed6c662008-01-07 17:25:53 +00004371- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4372
Georg Brandl3ee81df2008-05-17 18:14:43 +00004373- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4374 envvar and sys.dont_write_bytecode attribute. All these can be set
4375 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004376
Georg Brandl3ee81df2008-05-17 18:14:43 +00004377- Improve some exception messages when Windows fails to load an
4378 extension module. Now we get for example '%1 is not a valid Win32
4379 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004380
Georg Brandl3ee81df2008-05-17 18:14:43 +00004381- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004383- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4384 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004385
Christian Heimes0a8143f2007-12-18 23:22:54 +00004386- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004387 and INF. float("nan"), float("inf") and float("-inf") now work on
4388 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004389
Georg Brandl3ee81df2008-05-17 18:14:43 +00004390- Compiler now generates simpler and faster code for dictionary
4391 literals. The oparg for BUILD_MAP now indicates an estimated
4392 dictionary size. There is a new opcode, STORE_MAP, for adding
4393 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004394
Georg Brandl3ee81df2008-05-17 18:14:43 +00004395- Issue #1638: %zd configure test fails on Linux.

4405
Nick Coghlanef01d822007-12-03 12:55:17 +00004406- PEP 366: Allow explicit relative imports when executing modules
4407 inside packages with the -m switch via a new module level
4408 __package__ attribute.
4409
Georg Brandl3ee81df2008-05-17 18:14:43 +00004410- Issue #1402: Fix a crash on exit, when another thread is still
4411 running, and if the deallocation of its frames somehow calls the
4412 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004413

4423 file can now be directly executed by passing their name to the
4424 interpreter. The directory/zipfile is automatically inserted as the
4425 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004426
Georg Brandl3ee81df2008-05-17 18:14:43 +00004427- Issue #1265: Fix a problem with sys.settrace, if the tracing
4428 function uses a generator expression when at the same time the
4429 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004430
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004431- sets and frozensets now have an isdisjoint() method.
4432
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004433- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004435- Fix warnings found by the new version of the Coverity checker.
4436
Georg Brandl21e99f42010-03-07 15:23:59 +00004437- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004438 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4439 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004440
Georg Brandl3ee81df2008-05-17 18:14:43 +00004441- Issue #1686386: Tuple's tp_repr did not take into account the
4442 possibility of having a self-referential tuple, which is possible
4443 from C code. Nor did object's tp_str consider that a type's tp_str
4444 could do something that could lead to an inifinite recursion.
4445 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4446 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004448- Issue #1164: It was possible to trigger deadlock when using the
4449 'print' statement to write to a file since the GIL was not released
4450 as needed. Now PyObject_Print() does the right thing along with
4451 various tp_print implementations of the built-in types and those in

Brett Cannon1e534b52007-09-07 04:18:30 +00004461- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004462 PyObject_Call() never calling back out to Python code to trigger
4463 recursion depth updates/checks. Required the creation of a static
4464 RuntimeError instance in case normalizing an exception put the
4465 recursion check value past its limit. Fixes crashers
4466 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004481- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004482 __*__ attributes. (Some already existed, e.g., __doc__ and
4483 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004484
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004485- Add -3 option to the interpreter to warn about features that are

4489 calls.
4490
Collin Winter62903052007-05-18 23:11:24 +00004491- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004492 "except E as target:". This is to provide forwards compatibility
4493 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004494
Brett Cannon229cee22007-05-05 01:34:02 +00004495- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004500- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004501 setting a plain string, ie don't expand to single letter identifiers.
4502
Raymond Hettinger13936692007-04-11 18:40:58 +00004503- Request #1191699: Slices can now be pickled.
4504
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004505- Request #1193128: str.translate() now allows a None argument for
4506 translations that only remove characters without re-mapping the
4507 remaining characters.
4508
Georg Brandl5cb76c12007-03-21 09:00:39 +00004509- Patch #1682205: a TypeError while unpacking an iterable is no longer

4513
Guido van Rossum143b5642007-03-23 04:58:42 +00004514- Bug #1683368: The object.__init__() and object.__new__() methods are
4515 now stricter in rejecting excess arguments. The only time when
4516 either allows excess arguments is when it is not overridden and the
4517 other one is. For backwards compatibility, when both are
4518 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004519 warning later). Also, type.__init__() insists on the same signature
4520 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004521
Georg Brandl3ee81df2008-05-17 18:14:43 +00004522- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4523 object to complex using its __complex__() method before falling back
4524 to the __float__() method. Therefore, the functions in the cmath
4525 module now can operate on objects that define a __complex__()
4526 method.

4543
Georg Brandl7b9c5552007-03-12 14:30:05 +00004544- Bug #1678647: write a newline after printing an exception in any
4545 case, even when converting the value to a string failed.
4546
Georg Brandl871f1bc2007-03-12 13:17:36 +00004547- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004548 its argument, if it exists. If not, it will work like before. This
4549 allows customizing the output of dir() in the presence of a
4550 __getattr__().

4559 parthensized forms. This means complex(repr(x)) now works instead of
4560 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004561
Georg Brandlaa2321b2007-03-07 00:40:28 +00004562- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004563 makes the filenames the warning module prints much more sensible
4564 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004565

4567 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004568 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00004577- Patch #1674228: when assigning a slice (old-style), check for the
4578 sq_ass_slice instead of the sq_slice slot.
4579
Georg Brandl3ee81df2008-05-17 18:14:43 +00004580- When printing an unraisable error, don't print exceptions. before

Thomas Heller2456a3c2007-03-09 20:39:22 +00005190- Bug #1651235: When a tuple was passed to a ctypes function call,
5191 Python would crash instead of raising an error.
5192
Thomas Hellerc2f77252007-03-09 19:21:28 +00005193- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
5194 returned string up to the first NUL character.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005206- unittest now verifies more of its assumptions. In particular,
5207 TestCase and TestSuite subclasses (not instances) are no longer
5208 accepted in TestSuite.addTest(). This should cause no
5209 incompatibility since it never made sense with ordinary subclasses
5210 -- the failure just occurred later, with a more cumbersome
5211 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005498 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00005600 time so that opening a database previously created with the DB_DUP
5601 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5602 opens. Specifically: dictionary assignment to a DB object will
5603 replace all values for a given key when the database allows
5604 duplicate values. DB users should use DB.put(k, v) when they want
5605 to store duplicates; not DB[k] = v.

5612 characters with ASCII value less than 32. Also, it correctly quotes
5613 dots only if they occur on a single line, as opposed to the previous
5614 behavior of quoting dots if they are the second character of any
5615 line.

5938-----
5939
Georg Brandl3ee81df2008-05-17 18:14:43 +00005940- Unified naming convention for free lists and their limits. All free
5941 lists in Object/ are named ``free_list``, the counter ``numfree``
5942 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5943 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005944
Georg Brandl3ee81df2008-05-17 18:14:43 +00005945- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5946 to ``PyTuple_SetItem``, it can be used to populate a brand new
5947 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005948
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005949- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005951- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5952 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5953 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005954
5955- Patch #1720595: add T_BOOL to the range of structmember types.
5956
5957- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5958 ``PyFloat_GetInfo()`` to the float API.
5959
Georg Brandl3ee81df2008-05-17 18:14:43 +00005960- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5961 of w# format code incorrectly truncated the length to an int, even
5962 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5963 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005964
Georg Brandl3ee81df2008-05-17 18:14:43 +00005965- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5966 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005968- PEP 3123: Provide forward compatibility with Python 3.0, while
5969 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5970 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005971
Georg Brandl3ee81df2008-05-17 18:14:43 +00005972- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5973 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005974
5975- Patch #1733960: Allow T_LONGLONG to accept ints.
5976
5977- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5978

5982
5983- Fix some leftovers from the conversion from int to Py_ssize_t
5984 (relevant to strings and sequences of more than 2**31 items).
5985
5986- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5987 outside of pystate.c and should not be necessary.
5988
Georg Brandl3ee81df2008-05-17 18:14:43 +00005989- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5990 absolute imports. In earlier versions they might have used relative
5991 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005992
Georg Brandl3ee81df2008-05-17 18:14:43 +00005993- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5994 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005995
Georg Brandl3ee81df2008-05-17 18:14:43 +00005996- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5997 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006003- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6004 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6005 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6006 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006007
Georg Brandl3ee81df2008-05-17 18:14:43 +00006008- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00006021- Removed the macfs module. It had been deprecated since Python 2.5.
6022 This lead to the deprecation of macostools.touched() as it relied
6023 solely on macfs and was a no-op under OS X.
