1065 In particular, fix extension module build failures when trying to use
1066 32-bit-only installer Pythons on systems with Xcode 4 (currently
1067 OS X 10.8, 10.7, and optionally 10.6).
1068 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1069 * Since Xcode 4 removes ppc support, extension module builds now
1070 check for ppc compiler support and by default remove ppc and
1071 ppc64 archs when they are not available.
1072 * Extension module builds now revert to using system installed
1073 headers and libs (/usr and /System/Library) if the SDK used
1074 to build the interpreter is not installed or has moved.
1075 * Try to avoid building extension modules with deprecated
1076 and problematic Apple llvm-gcc compiler. If original compiler
1077 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001501- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001502 has left two versions of customize_compiler, the original in
1503 distutils.sysconfig and another copy in distutils.ccompiler, with some
1504 parts of distutils calling one and others using the other.
1505 Complete the revert back to only having one in distutils.sysconfig as
1506 is the case in 3.x.
1507
Ned Deily0d0ea482012-02-10 12:59:06 +01001508- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1509 Distutils-based packages with C extension modules may fail because
1510 Apple has removed gcc-4.2, the version used to build python.org
1511 64-bit/32-bit Pythons. If the user does not explicitly override
1512 the default C compiler by setting the CC environment variable,
1513 Distutils will now attempt to compile extension modules with clang
1514 if gcc-4.2 is required but not found. Also as a convenience, if
1515 the user does explicitly set CC, substitute its value as the default
1516 compiler in the Distutils LDSHARED configuration variable for OS X.
1517 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1518 SDK, neither of which are available in Xcode 4. This change does not
1519 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001769- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1770 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1771 interpreter process. This could cause failures in non-Distutils subprocesses
1772 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001773 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001774 deployment target only in the environment of each build subprocess. It is
1775 still possible to globally override the default by setting
1776 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1777 greater or equal to the default value, the value with which the interpreter
1778 was built.

1808 the ticker doesn't have to wind down to zero from the old starting point
1809 before the new interval takes effect. And if the user increases the
1810 interval, it makes sure the new limit takes effect right away rather have an
1811 early task switch before recognizing the new interval.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003255- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3256 start byte and the continuation byte(s) are now considered invalid, instead
3257 of the number of bytes specified by the start byte.
3258 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3259 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3260 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3261 Previous versions returned a single u'\ufffd'.

3265 arises from the "Overriding __eq__ blocks inheritance ..." warning
3266 when turned into an exception: in this case the exception simply
3267 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003269- Issue #8748: Fix two issues with comparisons between complex and integer
3270 objects. (1) The comparison could incorrectly return True in some cases
3271 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3272 (2) The comparison raised an OverflowError for large integers, leading
3273 to unpredictable exceptions when combining integers and complex objects
3274 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003276- Issue #5211: Implicit coercion for the complex type is now completely

3657 with a non-empty format string. This is an effort to future-proof user
3658 code. If a derived class does not currently implement __format__ but later
3659 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003660 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003661 Python 3.3 and it will be an error in Python 3.4.

3717 return a result based on the numeric values of the operands; previously they
3718 returned an arbitrary result based on the relative ordering of id(float) and
3719 id(Decimal).

3723 read on demand and the named file is compiled immediately. (Original patch by
3724 Piotr Ożarowski).

3735 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3736 <=> complex, and complex <=> complex comparisons.

4111 strings,
4112 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Antoine Pitroud840e512010-02-04 20:20:18 +00004146- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004147 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004148 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004153- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004154 file position when calling `truncate()`. It would previously change the file
4155 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004156 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4157

4159 class used to represent files stored inside an archive. The new
4160 implementation is significantly faster and can be wrapped in a
4161 ``io.BufferedReader`` object for more speedups. It also solves an issue
4162 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4163 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004173- Issue #7748: Since unicode values are supported for some metadata options in
4174 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4175 encoded string for them. This ensures that the upload and register commands
4176 send the correct values to PyPI without any error.

4252
Georg Brandlba83f822010-03-14 09:50:54 +00004253- The ``__complex__()`` method is now looked up on the class of instances to
4254 make it consistent with other special methods.

4258
Mark Dickinson1b34d252010-01-01 17:27:30 +00004259- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004260 DeprecationWarning when passed a float argument where an integer was expected.
4261 These functions and methods now raise TypeError instead. The majority of the
4262 effects of this change are in the extension modules, but some core functions
4263 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4264 and many unicode/str methods.

4278 of integers: the result of a/b is now correctly rounded for ints a and b (at
4279 least on IEEE 754 platforms), and in particular does not depend on the
4280 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004429- Issue #3382: 'F' formatting for float and complex now convert the result to
4430 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4431 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004432
Georg Brandlba83f822010-03-14 09:50:54 +00004433- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4434 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004435
Georg Brandlba83f822010-03-14 09:50:54 +00004436- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4437 1e-100 used to raise OverflowError, but now gives the requested 120
4438 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004439

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004446
Georg Brandlba83f822010-03-14 09:50:54 +00004447- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4448 decimal string that's guaranteed to round back to x under correct rounding
4449 (with round-half-to-even rounding mode). Previously it gave a string based on
4450 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4451 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4452 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004453
Georg Brandlba83f822010-03-14 09:50:54 +00004454- Issue #7117: On almost all platforms: float-to-string and string-to-float
4455 conversions within Python are now correctly rounded. Places these conversions
4456 occur include: str for floats and complex numbers; the float and complex
4457 constructors; old-style and new-style numeric formatting; serialization and
4458 deserialization of floats and complex numbers using marshal, pickle and json;
4459 parsing of float and imaginary literals in Python code; Decimal-to-float
4460 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004461
Georg Brandlba83f822010-03-14 09:50:54 +00004462 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4463 providing correctly-rounded strtod and dtoa C functions. This code is
4464 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4465 the C compiler. There may be a small number of platforms on which correct
4466 operation of this code cannot be guaranteed, so the code is not used: notably,
4467 this applies to platforms where the C double format is not IEEE 754 binary64,
4468 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4469 and Python's configure script is unable to determine how to change the FPU
4470 precision. On these platforms conversions use the platform strtod and dtoa,
4471 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004473- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4474 uses the correctly-rounded string <-> float conversions described above (when
4475 available), and so produces correctly rounded results that will display nicely
4476 under the float repr. There are two related small changes: (1) round now
4477 accepts any class with an ``__index__()`` method for its second argument (but
4478 no longer accepts floats for the second argument), and (2) an excessively
4479 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4480 raises an exception.

4483
Georg Brandlba83f822010-03-14 09:50:54 +00004484- Fix several issues with ``compile()``. The input can now contain Windows and

4630 of 12. Previously, the behavior the same but with a default precision of 6.
4631 This more closely matches ``str()``, and reduces surprises when adding

6065 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6066 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6067 neither __int__ nor __long__, TypeError used to be raised (with a
6068 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and

Georg Brandlba83f822010-03-14 09:50:54 +00006122 leak-chasing test runs give sensible results. The previous method of reaping
6123 threads could return successfully while some Thread objects were still
6124 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00006125
Georg Brandlba83f822010-03-14 09:50:54 +00006126- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

6142 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006143 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6144 the tests if DISPLAY is defined but can't be used.

6150 import both normal and optimised versions of modules. test_heapq and
6151 test_warnings have been adjusted to use it, tests for other modules with both
6152 C and Python implementations in the stdlib can be adjusted to use it over

6162 should cause a test to be skipped are now done using import_module from test
6163 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006266- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6268 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6269 ``printf`` function, whereas PyString_FromFormat has an independent
6270 implementation and uses "%zd" on all platforms for size_t values.
6271 This makes a difference on win64, where ``printf`` needs "%Id" to display

6280 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006282- Issue #3751: str.rpartition would perform a left-partition when called with
6283 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006287- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006288 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006289 was correctly parsed but parsing of subsequent arguments failed.
6290
Vinay Sajip35e3b032008-09-01 14:33:59 +00006291- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006292 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6293 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6294 when given a tuple of classes as second argument, were looking up
6295 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6296 type object.
6297
Neal Norwitz18aa3882008-08-24 05:04:52 +00006298- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006367 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6368 for catch_warnings() also led to an improvement in the raising of a
6369 DeprecationWarning related to warnings.warn_explicit().
6370

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006435What's New in Python 2.6 beta 3?
6436================================
6437
Barry Warsaw07a4a382008-08-21 01:15:08 +00006438*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006439
6440Core and Builtins
6441-----------------
6442
Guido van Rossumf8402962008-08-20 15:01:50 +00006443- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6444 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6445 extensions do not automatically benefit from the class attribute
6446 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6447 to their tp_flags field if they care. This is a backwards
6448 compatibility feature; in 3.0, all types will use the cache by
6449 default.
6450
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006451- Keyword arguments can now follow starred arguments. (``f(a, *args,
6452 keyword=23)`` is now valid syntax.)
6453
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006454- ctypes function pointers that are COM methods have a boolean True
6455 value again.
6456
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006457- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6458 by denying s# to parse objects that have a releasebuffer procedure,
6459 and introducing s*.
6460
Georg Brandl1e13ea92008-08-11 09:07:59 +00006461- Issue #3537: Fix an assertion failure when an empty but presized dict
6462 object was stored in the freelist.
6463
Mark Dickinsonb6467572008-08-04 21:30:09 +00006464- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6465 ValueError consistently across platforms.
6466
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006467- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6468 (64bit Unix, for example), unichr() would truncate its argument and return
6469 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6470
Neal Norwitze7d8be82008-07-31 17:17:14 +00006471- Apply security patches from Apple.
6472
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006473- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6474 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6475
Antoine Pitrou92f82162008-07-25 22:22:08 +00006476- Issue #1819: function calls with several named parameters are now on
6477 average 35% faster (as measured by pybench).
6478
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006479- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6480 the python debugger steps into a class statement: the free variables (local
6481 variables defined in an outer scope) would be deleted from the outer scope.
6482
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006483- Issue #2620: Overflow checking when allocating or reallocating memory
6484 was not always being done properly in some python types and extension
6485 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6486 all been updated to perform better checks and places in the code that
6487 would previously leak memory on the error path when such an allocation
6488 failed have been fixed.

6491-------
6492
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006493- Issue #3612: Added some missing basic types in ctypes.wintypes.
6494
Benjamin Petersone977ad42008-08-20 01:42:01 +00006495- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6496 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6497
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006498- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6499 version reported by these tools does not necessarily follow the python
6500 version numbering scheme, so the module is less strict when parsing it.
6501
Nick Coghlanf70385a2008-08-18 12:42:46 +00006502- Issue #2235: Added Py3k warnings for types which will become unhashable
6503 under the stricter __hash__ inheritance rules in 3.0. Several types
6504 which did not meet the rules for hash invariants and were already
6505 unhashable in 3.0 have now been explicitly flagged as unhashable in
6506 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6507 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6508
Brett Cannon88f801d2008-08-18 00:46:22 +00006509- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6510 imported into the module but exposed as part of the module's API.
6511
Brett Cannon7b96f072008-08-18 00:41:11 +00006512- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6513
Brett Cannon46225e72008-08-18 00:36:52 +00006514- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

6517
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006518- Issue #3575: Incremental decoder's decode function now takes bytearray
6519 by using 's*' instead of 't#'.
6520
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006521- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006522 fails unicode conversion on 2nd parameter. (windows only)
6523
Georg Brandl222e2082010-08-01 22:27:39 +00006524- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006525 in a redirect.
6526
Brett Cannonabe423e2008-08-16 21:47:07 +00006527- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006528 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006529
Facundo Batistaeb90b782008-08-16 14:44:07 +00006530- Issue #2776: fixed small issue when handling an URL with double slash
6531 after a 302 response in the case of not going through a proxy.
6532
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006533- Issue #2676: in the email package, content-type parsing was hanging on
6534 pathological input because of quadratic or exponential behaviour of a
6535 regular expression.
6536
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006537- Issue #3476: binary buffered reading through the new "io" library is now
6538 thread-safe.
6539
Brett Cannonbf3157b2008-08-14 05:00:03 +00006540- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6541 since mimetools itself is deprecated. Because modules are cached, all
6542 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6543
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006544- Issue #3134: shutil referenced undefined WindowsError symbol.
6545
Robert Schuppenies14646332008-08-10 11:01:53 +00006546- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6547 menu entries were not deleted.
6548
Brett Cannon83e81842008-08-09 23:30:55 +00006549- Copied the implementation of reduce() to _functools.reduce() to have a
6550 version that did not raise a DeprecationWarning under -3.
6551
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006552- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6553 a MemoryError rather than silently stop the iteration.
6554
Guido van Rossum59ce9012008-08-09 14:55:34 +00006555- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6556 to _sre.compile() will now be rejected. This should not affect anybody
6557 since the re.compile() function never generates invalid re-bytecode.
6558
Skip Montanaroa032bf42008-08-08 22:52:51 +00006559- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6560 upon first access it can be automatically initialized from the csv file if
6561 it wasn't initialized during instantiation.
6562
Brett Cannon3aa2a492008-08-06 22:28:09 +00006563- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as

6635-----------------
6636
Georg Brandl3e483f62008-07-16 22:57:41 +00006637- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6638 its methods now allow for items objects that can be converted to
6639 an integer using operator.index().
6640
Mark Dickinson64b7e502008-07-16 09:40:03 +00006641- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6642 produced a ValueError instead of giving the correct float.
6643
Eric Smitha5fa5a22008-07-16 00:11:49 +00006644- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6645 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6646
Mark Dickinson7103aa42008-07-15 19:08:33 +00006647- Issue #3008: the float type has a new instance method 'float.hex'
6648 and a new class method 'float.fromhex' to convert floating-point
6649 numbers to and from hexadecimal strings, respectively.
6650
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006651- Issue #2235: __hash__ is once again inherited by default. To allow
6652 collections.Hashable to remain meaningful in the presence of the
6653 default hash implementation (object.__hash__), it is now possible
6654 to explicit block inheritance of hash by setting __hash__=None at
6655 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6656 level.
6657
Nick Coghlanb028f502008-07-13 14:52:36 +00006658- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6659 the parent module cannot be found while performing an absolute import.
6660 This means that an incorrectly defined __package__ attribute will
6661 now only prevent relative imports in that module rather than causing
6662 all imports from that module to fail.
6663
Nick Coghlan14ff9942008-07-08 14:21:42 +00006664- Issue #2517: Allow unicode messages in Exceptions again by correctly

6674 another thread's dictionary.
6675
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006676- Issue #3004: Minor change to slice.indices(): the start and stop
6677 arguments are now treated identically, making the behaviour easier
6678 to describe and understand. For example, slice(None, -10,
6679 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6680 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6681 10, -1).
6682
Georg Brandl278fc502008-07-19 12:46:12 +00006683- Issue #3219: Calling a function with repeated keyword arguments,
6684 f(a=2, a=23), would not cause a syntax error. This was a regression
6685 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006723- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6724 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006725 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006726 content-length. The problem had been corrected in the 2.4 branch, but never
6727 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006742- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7130
Brett Cannonb61d8012008-05-11 23:39:04 +00007131- ``Lib/lib-old`` is now added to sys.path.
7132
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007133- On MacOS X it is now possible to install the framework in 64-bit
7134 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007135 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007136
7137 This is controlled by the configure argument ``--with-universal-archs``:
7138
7139 - ``--with-universal-archs=all``: install 4-way universal
7140
7141 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7142
7143 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7144
7145 This option should be used in combination with ``--enable-universalsdk=``.
7146
7147 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7152
Georg Brandl74a1dea2008-05-28 11:21:39 +00007153- Add ``PyType_Modified()`` as a public API to clear the type cache.
7154
7155- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00007156
7157- The PyString functions have been renamed to PyBytes. A batch of
7158 defines were added so that the linker still sees the original
7159 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007197- Issue #1631171: Re-implement the 'warnings' module in C (the
7198 original Python code has been kept as backup). This will allow for
7199 using the 'warning's machinery in such places as the parser where
7200 use of pure Python code is not possible. Both the ``showarning()``
7201 and ``formatwarning()`` gain an optional 'line' argument which is
7202 not called by default for backwards-compatibility reasons. Setting
7203 ``warnings.showwarning()`` to an implementation that lacks support
7204 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007229- The getpass module has been improved on Unix. It now uses /dev/tty
7230 by default and uses stderr instead of stdout. A GetPassWarning is
7231 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007246- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007247 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007267- Issue #2550: The approach used by client/server code for obtaining
7268 ports to listen on in network-oriented tests has been refined in an
7269 effort to facilitate running multiple instances of the entire
7270 regression test suite in parallel without issue.
7271 test_support.bind_port() has been fixed such that it will always
7272 return a unique port -- which wasn't always the case with the
7273 previous implementation, especially if socket options had been set
7274 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7275 new implementation of bind_port() will actually raise an exception
7276 if it is passed an AF_INET/SOCK_STREAM socket with either the
7277 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7278 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7279 the socket it's been passed. This currently only applies to
7280 Windows. This option prevents any other sockets from binding to the
7281 host/port we've bound to, thus removing the possibility of the
7282 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7283 when a second SOCK_STREAM socket binds and accepts to a host/port
7284 that's already been bound by another socket. The optional preferred
7285 port parameter to bind_port() has been removed. Under no
7286 circumstances should tests be hard coding ports!
7287
7288 test_support.find_unused_port() has also been introduced, which will
7289 pass a temporary socket object to bind_port() in order to obtain an
7290 unused port. The temporary socket object is then closed and
7291 deleted, and the port is returned. This method should only be used
7292 for obtaining an unused port in order to pass to an external program
7293 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7294 a parameter to a server-oriented class that doesn't give you direct
7295 access to the underlying socket used.
7296
7297 Finally, test_support.HOST has been introduced, which should be used
7298 for the host argument of any relevant socket calls (i.e. bind and
7299 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007300
7301 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007302 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007303 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7304 test_asynchat and test_socket_ssl.
7305
Georg Brandl3ee81df2008-05-17 18:14:43 +00007306 It is now possible for multiple instances of the regression test
7307 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007586- Added the future_builtins module, which contains hex() and oct().
7587 These are the PEP 3127 version of these functions, designed to be
7588 compatible with the hex() and oct() builtins from Python 3.0. They
7589 differ slightly in their output formats from the existing, unchanged
7590 Python 2.6 builtins. The expected usage of the future_builtins
7591 module is:
7592 from future_builtins import hex, oct
7593
Eric Smith7ef40bf2008-02-20 23:34:22 +00007594- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7595 exponents for exponents with absolute value < 100. Follows C99
7596 standard. This is a change on Windows, which would use 3 digits.
7597 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7598 so that any alterations it does to the resulting string will be
7599 available in stringlib/formatter.h (for float.__format__).
7600
Eric Smith5a3c1352008-02-19 13:21:56 +00007601- Implemented PEP 3101, Advanced String Formatting. This adds a new
7602 builtin format(); a format() method for str and unicode; a
7603 __format__() method to object, str, unicode, int, long, float, and
7604 datetime; the class string.Formatter; and the C API
7605 PyObject_Format().
7606
Georg Brandl3ee81df2008-05-17 18:14:43 +00007607- Fixed several potential crashes, all caused by specially crafted
7608 __del__ methods exploiting objects in temporarily inconsistent
7609 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007611- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007612 prevent a possible crash: an Abstract Base Class would try to access
7613 a slot on a registered virtual subclass.

7619 in order to allow pymalloc to free more arenas. Python may give back
7620 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007621
Georg Brandl3ee81df2008-05-17 18:14:43 +00007622- Issue #2045: Fix an infinite recursion triggered when printing a
7623 subclass of collections.defaultdict, if its default_factory is set
7624 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007625
Christian Heimesf75dbef2008-02-08 00:11:31 +00007626- Fixed a minor memory leak in dictobject.c. The content of the free
7627 list was not freed on interpreter shutdown.
7628
Georg Brandl21e99f42010-03-07 15:23:59 +00007629- Limit free list of method and built-in function objects to 256

7633 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007634 to compact the internal free lists of pre-allocted ints and floats.
7635
Georg Brandl3ee81df2008-05-17 18:14:43 +00007636- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7637 calls. Python expected the return type int but the fork familie
7638 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007639

Georg Brandl3ee81df2008-05-17 18:14:43 +00007646- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7647 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007648
Georg Brandl3ee81df2008-05-17 18:14:43 +00007649- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7650 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007651
Georg Brandl3ee81df2008-05-17 18:14:43 +00007652- Patch #1473257: generator objects gain a gi_code attribute. This is
7653 the same object as the func_code attribute of the function that
7654 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007655
Georg Brandl3ee81df2008-05-17 18:14:43 +00007656- Issue #1920: "while 0" statements were completely removed by the
7657 compiler, even in the presence of an "else" clause, which is
7658 supposed to be run when the condition is false. Now the compiler
7659 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007660
Guido van Rossumeead05f2008-01-24 18:21:02 +00007661- A few crashers fixed: weakref_in_del.py (issue #1377858);
7662 loosing_dict_ref.py (issue #1303614, test67.py);
7663 borrowed_ref_[34].py (not in tracker).
7664
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007665- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007666 suppressed while an extension is loaded by calling SetErrorMode in
7667 dynload_win.c. The error is still reported properly.
7668
Georg Brandl3ee81df2008-05-17 18:14:43 +00007669- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007670 several extension methods and modules do not work without unicode
7671 support.
7672
Georg Brandl26543b12008-01-21 18:36:51 +00007673- Issue #1882: when compiling code from a string, encoding cookies in the
7674 second line of code were not always recognized correctly.
7675
Georg Brandl14404b62008-01-19 19:27:05 +00007676- Issue #1679: "0x" was taken as a valid integer literal.
7677
Georg Brandl6caad7d2008-01-26 14:19:22 +00007678- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007679 added.
7680
Christian Heimesc94e2b52008-01-14 04:13:37 +00007681- sys.float_info / PyFloat_GetInfo: The floating point information
7682 object was converted from a dict to a specialized structseq object.
7683
Georg Brandl3ee81df2008-05-17 18:14:43 +00007684- Patch #1816: Added sys.flags structseq. It exposes the status of
7685 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007686
Georg Brandl3ee81df2008-05-17 18:14:43 +00007687- Objects/structseq.c: Implemented new structseq representation. The
7688 patch makes structseqs (e.g. the return value of os.stat) more
7689 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007690
Georg Brandl3ee81df2008-05-17 18:14:43 +00007691- Patch #1700288: added a type attribute cache that caches method
7692 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007693
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007694- Bug #1776: __import__() no longer accepts filenames on any platform.
7695 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007696
Georg Brandlaed6c662008-01-07 17:25:53 +00007697- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7698
Georg Brandl3ee81df2008-05-17 18:14:43 +00007699- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7700 envvar and sys.dont_write_bytecode attribute. All these can be set
7701 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007702
Georg Brandl3ee81df2008-05-17 18:14:43 +00007703- Improve some exception messages when Windows fails to load an
7704 extension module. Now we get for example '%1 is not a valid Win32
7705 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007706
Georg Brandl3ee81df2008-05-17 18:14:43 +00007707- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007709- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7710 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007711
Christian Heimes0a8143f2007-12-18 23:22:54 +00007712- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007713 and INF. float("nan"), float("inf") and float("-inf") now work on
7714 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007715
Georg Brandl3ee81df2008-05-17 18:14:43 +00007716- Compiler now generates simpler and faster code for dictionary
7717 literals. The oparg for BUILD_MAP now indicates an estimated
7718 dictionary size. There is a new opcode, STORE_MAP, for adding
7719 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007720
Georg Brandl3ee81df2008-05-17 18:14:43 +00007721- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007726- Issue #1538: Avoid copying string in split/rsplit if the split char
7727 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007728
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007729- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007730 SystemError.
7731
Nick Coghlanef01d822007-12-03 12:55:17 +00007732- PEP 366: Allow explicit relative imports when executing modules
7733 inside packages with the -m switch via a new module level
7734 __package__ attribute.
7735

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007743 attribute of an empty cell object.
7744
Georg Brandl3ee81df2008-05-17 18:14:43 +00007745- Issue #1460: The utf-7 incremental decoder did not accept truncated
7746 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007747
Georg Brandl3ee81df2008-05-17 18:14:43 +00007748- Patch #1739468: Directories and zipfiles containing a __main__.py
7749 file can now be directly executed by passing their name to the
7750 interpreter. The directory/zipfile is automatically inserted as the
7751 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007752
Georg Brandl3ee81df2008-05-17 18:14:43 +00007753- Issue #1265: Fix a problem with sys.settrace, if the tracing
7754 function uses a generator expression when at the same time the
7755 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007756
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007757- sets and frozensets now have an isdisjoint() method.
7758
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007759- optimize the performance of builtin.sum().
7760
Neal Norwitz44f326e2007-10-05 05:29:17 +00007761- Fix warnings found by the new version of the Coverity checker.
7762
Georg Brandl21e99f42010-03-07 15:23:59 +00007763- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007764 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7765 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007766
Georg Brandl3ee81df2008-05-17 18:14:43 +00007767- Issue #1686386: Tuple's tp_repr did not take into account the
7768 possibility of having a self-referential tuple, which is possible
7769 from C code. Nor did object's tp_str consider that a type's tp_str
7770 could do something that could lead to an inifinite recursion.
7771 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7772 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007773
Georg Brandl3ee81df2008-05-17 18:14:43 +00007774- Issue #1164: It was possible to trigger deadlock when using the
7775 'print' statement to write to a file since the GIL was not released
7776 as needed. Now PyObject_Print() does the right thing along with
7777 various tp_print implementations of the built-in types and those in
7778 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007779
Georg Brandl3ee81df2008-05-17 18:14:43 +00007780- Issue #1147: Exceptions were directly allowing string exceptions in
7781 their throw() method even though string exceptions no longer
7782 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007783
Georg Brandl3ee81df2008-05-17 18:14:43 +00007784- Issue #1096: Prevent a segfault from getting the repr of a very
7785 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007786
Brett Cannon1e534b52007-09-07 04:18:30 +00007787- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007788 PyObject_Call() never calling back out to Python code to trigger
7789 recursion depth updates/checks. Required the creation of a static
7790 RuntimeError instance in case normalizing an exception put the
7791 recursion check value past its limit. Fixes crashers
7792 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007793
Georg Brandl3ee81df2008-05-17 18:14:43 +00007794- Patch #1031213: Decode source line in SyntaxErrors back to its

Georg Brandl7c3b50d2007-07-12 08:38:00 +00007797- Patch #1673759: add a missing overflow check when formatting floats
7798 with %G.
7799
Georg Brandl3ee81df2008-05-17 18:14:43 +00007800- Prevent expandtabs() on string and unicode objects from causing a
7801 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007802

Neal Norwitz0ac60192007-05-27 04:08:54 +00007807- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007808 __*__ attributes. (Some already existed, e.g., __doc__ and
7809 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007810
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007811- Add -3 option to the interpreter to warn about features that are
7812 deprecated and will be changed/removed in Python 3.0.
7813
Georg Brandl2134e752007-05-21 20:34:16 +00007814- Patch #1686487: you can now pass any mapping after '**' in function
7815 calls.
7816
Collin Winter62903052007-05-18 23:11:24 +00007817- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007818 "except E as target:". This is to provide forwards compatibility
7819 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007820
Brett Cannon229cee22007-05-05 01:34:02 +00007821- Deprecate BaseException.message as per PEP 352.
7822
Georg Brandl3ee81df2008-05-17 18:14:43 +00007823- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007824 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007825
Vinay Sajip8549ce32007-05-06 17:53:37 +00007826- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007827 setting a plain string, ie don't expand to single letter identifiers.
7828
Raymond Hettinger13936692007-04-11 18:40:58 +00007829- Request #1191699: Slices can now be pickled.
7830
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007831- Request #1193128: str.translate() now allows a None argument for
7832 translations that only remove characters without re-mapping the
7833 remaining characters.
7834
Georg Brandl5cb76c12007-03-21 09:00:39 +00007835- Patch #1682205: a TypeError while unpacking an iterable is no longer
7836 masked by a generic one with the message "unpack non-sequence".
7837
Neal Norwitzaa754b72007-03-21 06:39:48 +00007838- Remove unused file Python/fmod.c.
7839
Guido van Rossum143b5642007-03-23 04:58:42 +00007840- Bug #1683368: The object.__init__() and object.__new__() methods are
7841 now stricter in rejecting excess arguments. The only time when
7842 either allows excess arguments is when it is not overridden and the
7843 other one is. For backwards compatibility, when both are
7844 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007845 warning later). Also, type.__init__() insists on the same signature
7846 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007847
Georg Brandl3ee81df2008-05-17 18:14:43 +00007848- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7849 object to complex using its __complex__() method before falling back
7850 to the __float__() method. Therefore, the functions in the cmath
7851 module now can operate on objects that define a __complex__()
7852 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007853
Georg Brandl3ee81df2008-05-17 18:14:43 +00007854- Patch #1623563: allow __class__ assignment for classes with
7855 __slots__. The old and the new class are still required to have the
7856 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007857
Georg Brandl3ee81df2008-05-17 18:14:43 +00007858- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00007861- Patch #1462488: Python no longer segfaults when
7862 ``object.__reduce_ex__()`` is called with an object that is faking
7863 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007864
Georg Brandl3ee81df2008-05-17 18:14:43 +00007865- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00007868- Patch #1444529: the builtin compile() now accepts keyword arguments.
7869
Georg Brandl7b9c5552007-03-12 14:30:05 +00007870- Bug #1678647: write a newline after printing an exception in any
7871 case, even when converting the value to a string failed.
7872
Georg Brandl871f1bc2007-03-12 13:17:36 +00007873- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007874 its argument, if it exists. If not, it will work like before. This
7875 allows customizing the output of dir() in the presence of a
7876 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007877
Collin Winter276887b2007-03-12 16:11:39 +00007878- Patch #922167: Python no longer segfaults when faced with infinitely
7879 self-recursive reload() calls (as reported by bug #742342).
7880
Georg Brandl3ee81df2008-05-17 18:14:43 +00007881- Patch #1675981: remove unreachable code from ``type.__new__()``
7882 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00007883
Georg Brandl3ee81df2008-05-17 18:14:43 +00007884- Patch #1491866: change the complex() constructor to allow

8397 ".cpp" too.
8398
Facundo Batistad918a652007-04-24 13:54:38 +00008399- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008400 the client's request was successfully received, understood, and
8401 accepted. Now in these cases no error is raised in urllib (issue
8402 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008403

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008410- Added a timeout parameter to the constructor of other protocols
8411 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8412 work started with create_connection() and timeout in httplib, and
8413 closes patch #723312.
8414
Vinay Sajip8549ce32007-05-06 17:53:37 +00008415- Patch #1676823: Added create_connection() to socket.py, which may be
8416 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008417 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008418
Martin v. Löwis0af33882007-03-23 13:27:15 +00008419- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008426- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
8427 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00008428 directories.
8429

8431 GNOME or KDE browser, depending on whether there is a session of one
8432 of those present. Also, it tries the Windows default browser before
8433 trying Mozilla variants.

8439
Georg Brandlf66b6032007-03-14 08:27:52 +00008440- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008441 AttributeError instead of an IOError when the server's response
8442 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008443
Georg Brandl3ee81df2008-05-17 18:14:43 +00008444- Patch #957650: "%var%" environment variable references are now
8445 properly expanded in ntpath.expandvars(), also "~user" home
8446 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00008447
Georg Brandl3ee81df2008-05-17 18:14:43 +00008448- Patch #1429539: pdb now correctly initializes the __main__ module
8449 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008450 correctly now.
8451
Georg Brandlbad6f192007-03-13 21:32:56 +00008452- The nonobvious commands.getstatus() function is now deprecated.

8458
Georg Brandl3ee81df2008-05-17 18:14:43 +00008459- Patch #1530482: add pydoc.render_doc() which returns the
8460 documentation for a thing instead of paging it to stdout, which
8461 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008462
Georg Brandl3ee81df2008-05-17 18:14:43 +00008463- Patch #1533909: the timeit module now accepts callables in addition

8469 parameter which can be set to False to prevent the default
8470 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008471
Georg Brandl9e6b4702007-03-13 18:15:41 +00008472- Patch #1581073: add a flag to textwrap that prevents the dropping of
8473 whitespace while wrapping.
8474
Georg Brandl92a6bae2007-03-13 17:43:32 +00008475- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008476 are set for invalid interpolation sequences that would lead to
8477 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008478

8491
Georg Brandl94fe3f52007-03-13 09:32:11 +00008492- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00008493 field names in its exception message if you try to write a record
8494 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00008512

8520 returned string up to the first NUL character.
8521

8531
Georg Brandl3ee81df2008-05-17 18:14:43 +00008532- unittest now verifies more of its assumptions. In particular,
8533 TestCase and TestSuite subclasses (not instances) are no longer
8534 accepted in TestSuite.addTest(). This should cause no
8535 incompatibility since it never made sense with ordinary subclasses
8536 -- the failure just occurred later, with a more cumbersome
8537 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00008538

8546 given a unicode argument and os.listdir() returns unicode filenames.
8547
Georg Brandl3ee81df2008-05-17 18:14:43 +00008548- Patch #1673619: setup.py identifies extension modules it doesn't

8550 build.

8902 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8903 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00008920 time so that opening a database previously created with the DB_DUP
8921 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8922 opens. Specifically: dictionary assignment to a DB object will
8923 replace all values for a given key when the database allows
8924 duplicate values. DB users should use DB.put(k, v) when they want
8925 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008926

8932 characters with ASCII value less than 32. Also, it correctly quotes
8933 dots only if they occur on a single line, as opposed to the previous
8934 behavior of quoting dots if they are the second character of any
8935 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008936
