9Core and Builtins
10-----------------
11
Victor Stinner63c22fa2011-09-23 19:37:03 +020012- Issue #7732: Fix a crash on importing a module if a directory has the same
13 name than a Python module (e.g. "__init__.py"): don't close the file twice.
14
Mark Dickinsondbbed042011-09-19 16:38:08 +010015- Issue #12973: Fix overflow checks that invoked undefined behaviour in
16 int.__pow__. These overflow checks were causing int.__pow__ to produce
17 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010018 compiler optimizing the check away. Also fix similar overflow checks
19 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
20 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010021

Antoine Pitrou16166452011-07-12 22:04:20 +020031- Issue #12149: Update the method cache after a type's dictionnary gets
32 cleared by the garbage collector. This fixes a segfault when an instance
33 and its type get caught in a reference cycle, and the instance's
34 deallocator calls one of the methods on the type (e.g. when subclassing
35 IOBase). Diagnosis and patch by Davide Rizzo.
36
Victor Stinnerba8b3a22011-07-08 02:07:45 +020037- Issue #12501: Adjust callable() warning: callable() is only not supported in
38 Python 3.1. callable() is again supported in Python 3.2.
39
Victor Stinner59729ff2011-07-05 11:28:19 +020040- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and
41 os.write() clamp the length to INT_MAX on Windows.
42
Victor Stinnerd3c7e172011-05-30 23:49:13 +020043- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020044 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
45 raw_input() interrupted by CTRL+c.
46
Barry Warsawc5643282011-07-19 17:06:30 -040047- dict_proxy objects now display their contents rather than just the class
48 name.

177
Ned Deily87e82bb2011-06-28 19:52:59 -0700178- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
179 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
180 interpreter process. This could cause failures in non-Distutils subprocesses
181 and was unreliable since tests or user programs could modify the interpreter
182 environment after Distutils set it. Instead, have Distutils set the the
183 deployment target only in the environment of each build subprocess. It is
184 still possible to globally override the default by setting
185 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
186 greater or equal to the default value, the value with which the interpreter
187 was built.

193 Kitada.
194
R David Murrayf1138bb2011-06-17 22:23:04 -0400195- Issue #11700: mailbox proxy object close methods can now be called multiple
196 times without error, and _ProxyFile now closes the wrapped file.
197
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200198- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
199 connection if its getresponse() method fails with a socket error. Patch
200 written by Ezio Melotti.
201
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500202- Issue #9284: Allow inspect.findsource() to find the source of doctest
203 functions.
204
R David Murray873c5832011-06-09 16:01:09 -0400205- Issue #10694: zipfile now ignores garbage at the end of a zipfile.
206
Brian Curtincaea7e82011-06-08 19:29:53 -0500207- Issue #11583: Speed up os.path.isdir on Windows by using GetFileAttributes
208 instead of os.stat.
209
Mark Dickinsona493ca32011-06-04 18:24:15 +0100210- Issue #12080: Fix a performance issue in Decimal._power_exact that caused
211 some corner-case Decimal.__pow__ calls to take an unreasonably long time.
212

214
Barry Warsawc5643282011-07-19 17:06:30 -0400215- sys.setcheckinterval() now updates the current ticker count as well as
216 updating the check interval, so if the user decreases the check interval,
217 the ticker doesn't have to wind down to zero from the old starting point
218 before the new interval takes effect. And if the user increases the
219 interval, it makes sure the new limit takes effect right away rather have an
220 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700221
Victor Stinner776e69b2011-06-01 01:03:00 +0200222- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the
223 constructor has failed, e.g. because of an undeclared keyword argument. Patch

941 warning.
942
Benjamin Petersondc954242010-10-12 23:02:35 +0000943- Issue #10068: Global objects which have reference cycles with their module's
944 dict are now cleared again. This causes issue #7140 to appear again.
945
Mark Dickinsoncb61e5d2010-09-26 10:37:12 +0000946- Issue #9869: Make long() and PyNumber_Long return something of type

957 encoding and errors attributes instead of using utf-8 in strict mode, to get
958 the same behaviour than the print statement.
959
Antoine Pitrou9cf85f12010-09-01 21:17:34 +0000960- Issue #9737: Fix a crash when trying to delete a slice or an item from

1090 unhelpful TypeError when called on an unconnected socket. Original patch
1091 by Andrew Bennetts.
1092

1100
Raymond Hettinger20397532010-09-12 02:11:45 +00001101- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1102 This prevents user-created self-referencing ordered dictionaries from
1103 becoming permanently uncollectable GC garbage. The downside is that
1104 removing __del__ means that the internal doubly-linked list has to wait for
1105 GC collection rather than freeing memory immediately when the refcnt drops
1106 to zero.
1107
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001108- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1111
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001112- Issue #9792: In case of connection failure, socket.create_connection()
1113 would swallow the exception and raise a new one, making it impossible
1114 to fetch the original errno, or to filter timeout errors. Now the
1115 original error is re-raised.
1116
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001117- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1118 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1119 be updated back after the system call. Original patch by Brian Brazil.

1135 falling into recursion.
1136
R. David Murray7c4bf552010-08-25 01:45:57 +00001137- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1138 character years even if the message contains RFC822 two character years.
1139
Daniel Stutzbach91287322010-08-24 21:09:30 +00001140- Issue #8750: Fixed MutableSet's methods to correctly handle

1155 ignored by the buffered IO layer anymore.
1156
Benjamin Peterson52c36052010-08-21 03:03:22 +00001157- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1159
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001160- Issue #9626: the view methods for collections.OrderedDict() were returning

1165 comment indicating they are generated. Manually maintained MANIFESTs
1166 without this marker will not be overwritten or removed.
1167
Antoine Pitroue1436d12010-08-12 15:25:51 +00001168- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1169 and a BadZipfile error is raised if it doesn't match (as used to be the
1170 case in Python 2.5 and earlier).
1171
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001172- Issue #9550: a BufferedReader could issue an additional read when the
1173 original read request had been satisfied, which could block indefinitely
1174 when the underlying raw IO channel was e.g. a socket. Report and original
1175 patch by Jason V. Miller.
1176
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001177- Issue #9551: Don't raise TypeError when setting the value to None for

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001565- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1566 start byte and the continuation byte(s) are now considered invalid, instead
1567 of the number of bytes specified by the start byte.
1568 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1569 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1570 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

1581 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

1967 with a non-empty format string. This is an effort to future-proof user
1968 code. If a derived class does not currently implement __format__ but later
1969 adds its own __format__, it would most likely break user code that had

Georg Brandlba83f822010-03-14 09:50:54 +00002464 file position when calling `truncate()`. It would previously change the file
2465 position to the given argument, which goes against the tradition of

2469 class used to represent files stored inside an archive. The new
2470 implementation is significantly faster and can be wrapped in a
2471 ``io.BufferedReader`` object for more speedups. It also solves an issue
2472 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2568
Mark Dickinson1b34d252010-01-01 17:27:30 +00002569- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002570 DeprecationWarning when passed a float argument where an integer was expected.
2571 These functions and methods now raise TypeError instead. The majority of the
2572 effects of this change are in the extension modules, but some core functions
2573 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2574 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002739- Issue #3382: 'F' formatting for float and complex now convert the result to
2740 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2741 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002742
Georg Brandlba83f822010-03-14 09:50:54 +00002743- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2744 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002745
Georg Brandlba83f822010-03-14 09:50:54 +00002746- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2747 1e-100 used to raise OverflowError, but now gives the requested 120
2748 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00002749

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002756
Georg Brandlba83f822010-03-14 09:50:54 +00002757- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2758 decimal string that's guaranteed to round back to x under correct rounding
2759 (with round-half-to-even rounding mode). Previously it gave a string based on
2760 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2761 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2762 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002763
Georg Brandlba83f822010-03-14 09:50:54 +00002764- Issue #7117: On almost all platforms: float-to-string and string-to-float
2765 conversions within Python are now correctly rounded. Places these conversions
2766 occur include: str for floats and complex numbers; the float and complex
2767 constructors; old-style and new-style numeric formatting; serialization and
2768 deserialization of floats and complex numbers using marshal, pickle and json;
2769 parsing of float and imaginary literals in Python code; Decimal-to-float
2770 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002771
Georg Brandlba83f822010-03-14 09:50:54 +00002772 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2773 providing correctly-rounded strtod and dtoa C functions. This code is
2774 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2775 the C compiler. There may be a small number of platforms on which correct
2776 operation of this code cannot be guaranteed, so the code is not used: notably,
2777 this applies to platforms where the C double format is not IEEE 754 binary64,
2778 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2779 and Python's configure script is unable to determine how to change the FPU
2780 precision. On these platforms conversions use the platform strtod and dtoa,
2781 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002782
Georg Brandlba83f822010-03-14 09:50:54 +00002783- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2784 uses the correctly-rounded string <-> float conversions described above (when
2785 available), and so produces correctly rounded results that will display nicely
2786 under the float repr. There are two related small changes: (1) round now
2787 accepts any class with an ``__index__()`` method for its second argument (but
2788 no longer accepts floats for the second argument), and (2) an excessively
2789 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2790 raises an exception.

2793
Georg Brandlba83f822010-03-14 09:50:54 +00002794- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002932
Georg Brandlba83f822010-03-14 09:50:54 +00002933 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2934 (2) parsing of strings representing infinities and nans was locale aware; and
2935 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002937- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2938 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2939 but with at least one decimal point and with a default precision
2940 of 12. Previously, the behavior the same but with a default precision of 6.
2941 This more closely matches ``str()``, and reduces surprises when adding
2942 alignment flags to the empty presentation type. This also affects the new
2943 complex.__format__ in the same way.
2944
2945- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2946 classtype's, even if it was None. property now inserts the __doc__ into the
2947 subclass instance __dict__.

3017 internal representation of integers, for performance reasons. Base 2**30 is
3018 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00004429 leak-chasing test runs give sensible results. The previous method of reaping
4430 threads could return successfully while some Thread objects were still

Georg Brandl2bd92a52009-10-11 21:10:07 +00004551- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00004552 AttributeError instead of RuntimeError, depending in which C API call
4553 exactly the recursion limit is exceeded. Consequently, both exception types
4554 are caught and silenced.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004571- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4572
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004573- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4574 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4575 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4576 ``printf`` function, whereas PyString_FromFormat has an independent
4577 implementation and uses "%zd" on all platforms for size_t values.
4578 This makes a difference on win64, where ``printf`` needs "%Id" to display
4579 64bit values.
4580
Benjamin Peterson97179b02008-09-09 20:55:01 +00004581- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4582 error.
4583
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004584- Issue #3777: long() applied to a float object now always return a long
4585 object; previously an int would be returned for small values. the __long__
4586 method is allowed to return either an int or a long, but the behaviour of
4587 float objects should not change to respect backward compatibility.
4588
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004589- Issue #3751: str.rpartition would perform a left-partition when called with
4590 a unicode argument.
4591
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004592- Issue #3683: Fix compilation when --without-threads is given.
4593
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004594- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004595 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004596 was correctly parsed but parsing of subsequent arguments failed.
4597
Vinay Sajip35e3b032008-09-01 14:33:59 +00004598- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004599 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4600 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4601 when given a tuple of classes as second argument, were looking up
4602 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4603 type object.
4604
Neal Norwitz18aa3882008-08-24 05:04:52 +00004605- Fix crashes on memory allocation failure found with failmalloc.
4606
4607- Fix memory leaks found with valgrind and update suppressions file.
4608
4609- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4610
4611- Fix problem using wrong name in decimal module reported by pychecker.
4612
Christian Heimes7d4c3172008-08-22 19:47:25 +00004613- Silenced another compiler warning about a used but not defined
4614 function 'stringlib_contains_obj'.

4617 ``__delslice__``.
4618
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004619- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4620 library targets in the Makefile.
4621
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004622- Issue #1204: The configure script now tests for additional libraries
4623 that may be required when linking against readline. This fixes issues
4624 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00004648 return a list or None rather than a custom object.
4649
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004650- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004674 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4675 for catch_warnings() also led to an improvement in the raising of a
4676 DeprecationWarning related to warnings.warn_explicit().
4677
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004678- The deprecation warnings for the old camelCase threading API were removed.

4747Core and Builtins
4748-----------------
4749
Guido van Rossumf8402962008-08-20 15:01:50 +00004750- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4751 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4752 extensions do not automatically benefit from the class attribute
4753 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4754 to their tp_flags field if they care. This is a backwards
4755 compatibility feature; in 3.0, all types will use the cache by
4756 default.
4757
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004758- Keyword arguments can now follow starred arguments. (``f(a, *args,
4759 keyword=23)`` is now valid syntax.)
4760
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004761- ctypes function pointers that are COM methods have a boolean True
4762 value again.
4763
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004764- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4765 by denying s# to parse objects that have a releasebuffer procedure,
4766 and introducing s*.
4767
Georg Brandl1e13ea92008-08-11 09:07:59 +00004768- Issue #3537: Fix an assertion failure when an empty but presized dict
4769 object was stored in the freelist.
4770
Mark Dickinsonb6467572008-08-04 21:30:09 +00004771- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4772 ValueError consistently across platforms.
4773
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004774- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4775 (64bit Unix, for example), unichr() would truncate its argument and return
4776 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4777
Neal Norwitze7d8be82008-07-31 17:17:14 +00004778- Apply security patches from Apple.
4779
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004780- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4781 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4782
Antoine Pitrou92f82162008-07-25 22:22:08 +00004783- Issue #1819: function calls with several named parameters are now on
4784 average 35% faster (as measured by pybench).
4785
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004786- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4787 the python debugger steps into a class statement: the free variables (local
4788 variables defined in an outer scope) would be deleted from the outer scope.
4789
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004790- Issue #2620: Overflow checking when allocating or reallocating memory
4791 was not always being done properly in some python types and extension
4792 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4793 all been updated to perform better checks and places in the code that
4794 would previously leak memory on the error path when such an allocation
4795 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00004802- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4803 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4804
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004805- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4806 version reported by these tools does not necessarily follow the python
4807 version numbering scheme, so the module is less strict when parsing it.
4808
Nick Coghlanf70385a2008-08-18 12:42:46 +00004809- Issue #2235: Added Py3k warnings for types which will become unhashable
4810 under the stricter __hash__ inheritance rules in 3.0. Several types
4811 which did not meet the rules for hash invariants and were already
4812 unhashable in 3.0 have now been explicitly flagged as unhashable in
4813 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4814 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4815
Brett Cannon88f801d2008-08-18 00:46:22 +00004816- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4817 imported into the module but exposed as part of the module's API.
4818
Brett Cannon7b96f072008-08-18 00:41:11 +00004819- Remove an unneeded import of abc.ABCMeta from 'inspect'.

4824
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004825- Issue #3575: Incremental decoder's decode function now takes bytearray
4826 by using 's*' instead of 't#'.
4827
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004828- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004829 fails unicode conversion on 2nd parameter. (windows only)

4929
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004930- Issue #643841: The language reference now provides more detailed

4943
Georg Brandl3e483f62008-07-16 22:57:41 +00004944- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4945 its methods now allow for items objects that can be converted to
4946 an integer using operator.index().
4947
Mark Dickinson64b7e502008-07-16 09:40:03 +00004948- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4949 produced a ValueError instead of giving the correct float.
4950
Eric Smitha5fa5a22008-07-16 00:11:49 +00004951- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4952 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4953
Mark Dickinson7103aa42008-07-15 19:08:33 +00004954- Issue #3008: the float type has a new instance method 'float.hex'
4955 and a new class method 'float.fromhex' to convert floating-point
4956 numbers to and from hexadecimal strings, respectively.
4957
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004958- Issue #2235: __hash__ is once again inherited by default. To allow
4959 collections.Hashable to remain meaningful in the presence of the
4960 default hash implementation (object.__hash__), it is now possible
4961 to explicit block inheritance of hash by setting __hash__=None at
4962 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4963 level.
4964
Nick Coghlanb028f502008-07-13 14:52:36 +00004965- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4966 the parent module cannot be found while performing an absolute import.
4967 This means that an incorrectly defined __package__ attribute will
4968 now only prevent relative imports in that module rather than causing
4969 all imports from that module to fail.
4970
Nick Coghlan14ff9942008-07-08 14:21:42 +00004971- Issue #2517: Allow unicode messages in Exceptions again by correctly

4981 another thread's dictionary.
4982
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004983- Issue #3004: Minor change to slice.indices(): the start and stop
4984 arguments are now treated identically, making the behaviour easier
4985 to describe and understand. For example, slice(None, -10,
4986 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4987 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4988 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00004990- Issue #3219: Calling a function with repeated keyword arguments,

4992 from 2.4 caused by the switch to the new compiler.

5031 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005032 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005033 content-length. The problem had been corrected in the 2.4 branch, but never

5439
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005440- On MacOS X it is now possible to install the framework in 64-bit
5441 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005442 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005443
5444 This is controlled by the configure argument ``--with-universal-archs``:
5445
5446 - ``--with-universal-archs=all``: install 4-way universal
5447
5448 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5449
5450 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5451
5452 This option should be used in combination with ``--enable-universalsdk=``.
5453
5454 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005504- Issue #1631171: Re-implement the 'warnings' module in C (the
5505 original Python code has been kept as backup). This will allow for
5506 using the 'warning's machinery in such places as the parser where
5507 use of pure Python code is not possible. Both the ``showarning()``
5508 and ``formatwarning()`` gain an optional 'line' argument which is
5509 not called by default for backwards-compatibility reasons. Setting
5510 ``warnings.showwarning()`` to an implementation that lacks support
5511 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005574- Issue #2550: The approach used by client/server code for obtaining
5575 ports to listen on in network-oriented tests has been refined in an
5576 effort to facilitate running multiple instances of the entire
5577 regression test suite in parallel without issue.
5578 test_support.bind_port() has been fixed such that it will always
5579 return a unique port -- which wasn't always the case with the
5580 previous implementation, especially if socket options had been set
5581 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5582 new implementation of bind_port() will actually raise an exception
5583 if it is passed an AF_INET/SOCK_STREAM socket with either the
5584 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5585 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5586 the socket it's been passed. This currently only applies to
5587 Windows. This option prevents any other sockets from binding to the
5588 host/port we've bound to, thus removing the possibility of the
5589 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5590 when a second SOCK_STREAM socket binds and accepts to a host/port
5591 that's already been bound by another socket. The optional preferred
5592 port parameter to bind_port() has been removed. Under no
5593 circumstances should tests be hard coding ports!
5594
5595 test_support.find_unused_port() has also been introduced, which will
5596 pass a temporary socket object to bind_port() in order to obtain an
5597 unused port. The temporary socket object is then closed and
5598 deleted, and the port is returned. This method should only be used
5599 for obtaining an unused port in order to pass to an external program
5600 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5601 a parameter to a server-oriented class that doesn't give you direct
5602 access to the underlying socket used.
5603
5604 Finally, test_support.HOST has been introduced, which should be used
5605 for the host argument of any relevant socket calls (i.e. bind and
5606 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005607
5608 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005609 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005610 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5611 test_asynchat and test_socket_ssl.
5612
Georg Brandl3ee81df2008-05-17 18:14:43 +00005613 It is now possible for multiple instances of the regression test
5614 suite to run in parallel without issue.

5672 this case, like normal unicode literals and the 'unicode-escape'

Eric Smitha73fbe72008-02-23 03:09:44 +00005893- Added the future_builtins module, which contains hex() and oct().
5894 These are the PEP 3127 version of these functions, designed to be
5895 compatible with the hex() and oct() builtins from Python 3.0. They
5896 differ slightly in their output formats from the existing, unchanged
5897 Python 2.6 builtins. The expected usage of the future_builtins
5898 module is:
5899 from future_builtins import hex, oct
5900
Eric Smith7ef40bf2008-02-20 23:34:22 +00005901- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5902 exponents for exponents with absolute value < 100. Follows C99
5903 standard. This is a change on Windows, which would use 3 digits.
5904 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5905 so that any alterations it does to the resulting string will be
5906 available in stringlib/formatter.h (for float.__format__).
5907
Eric Smith5a3c1352008-02-19 13:21:56 +00005908- Implemented PEP 3101, Advanced String Formatting. This adds a new
5909 builtin format(); a format() method for str and unicode; a
5910 __format__() method to object, str, unicode, int, long, float, and
5911 datetime; the class string.Formatter; and the C API
5912 PyObject_Format().
5913
Georg Brandl3ee81df2008-05-17 18:14:43 +00005914- Fixed several potential crashes, all caused by specially crafted
5915 __del__ methods exploiting objects in temporarily inconsistent
5916 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005925- Clear all free lists during a gc.collect() of the highest generation
5926 in order to allow pymalloc to free more arenas. Python may give back
5927 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005928
Georg Brandl3ee81df2008-05-17 18:14:43 +00005929- Issue #2045: Fix an infinite recursion triggered when printing a
5930 subclass of collections.defaultdict, if its default_factory is set
5931 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005932
Christian Heimesf75dbef2008-02-08 00:11:31 +00005933- Fixed a minor memory leak in dictobject.c. The content of the free
5934 list was not freed on interpreter shutdown.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005959- Patch #1473257: generator objects gain a gi_code attribute. This is
5960 the same object as the func_code attribute of the function that
5961 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005962
Georg Brandl3ee81df2008-05-17 18:14:43 +00005963- Issue #1920: "while 0" statements were completely removed by the
5964 compiler, even in the presence of an "else" clause, which is
5965 supposed to be run when the condition is false. Now the compiler
5966 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005967
Guido van Rossumeead05f2008-01-24 18:21:02 +00005968- A few crashers fixed: weakref_in_del.py (issue #1377858);
5969 loosing_dict_ref.py (issue #1303614, test67.py);
5970 borrowed_ref_[34].py (not in tracker).
5971
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005972- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005973 suppressed while an extension is loaded by calling SetErrorMode in
5974 dynload_win.c. The error is still reported properly.
5975
Georg Brandl3ee81df2008-05-17 18:14:43 +00005976- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005977 several extension methods and modules do not work without unicode
5978 support.
5979
Georg Brandl26543b12008-01-21 18:36:51 +00005980- Issue #1882: when compiling code from a string, encoding cookies in the

5984
Georg Brandl6caad7d2008-01-26 14:19:22 +00005985- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005986 added.
5987
Christian Heimesc94e2b52008-01-14 04:13:37 +00005988- sys.float_info / PyFloat_GetInfo: The floating point information
5989 object was converted from a dict to a specialized structseq object.
5990
Georg Brandl3ee81df2008-05-17 18:14:43 +00005991- Patch #1816: Added sys.flags structseq. It exposes the status of
5992 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005993
Georg Brandl3ee81df2008-05-17 18:14:43 +00005994- Objects/structseq.c: Implemented new structseq representation. The
5995 patch makes structseqs (e.g. the return value of os.stat) more
5996 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005997
Georg Brandl3ee81df2008-05-17 18:14:43 +00005998- Patch #1700288: added a type attribute cache that caches method
5999 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006000
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006001- Bug #1776: __import__() no longer accepts filenames on any platform.
6002 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00006004- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6005
Georg Brandl3ee81df2008-05-17 18:14:43 +00006006- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6007 envvar and sys.dont_write_bytecode attribute. All these can be set
6008 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006009
Georg Brandl3ee81df2008-05-17 18:14:43 +00006010- Improve some exception messages when Windows fails to load an
6011 extension module. Now we get for example '%1 is not a valid Win32
6012 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006013

Christian Heimes0a8143f2007-12-18 23:22:54 +00006019- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006020 and INF. float("nan"), float("inf") and float("-inf") now work on
6021 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006022
Georg Brandl3ee81df2008-05-17 18:14:43 +00006023- Compiler now generates simpler and faster code for dictionary
6024 literals. The oparg for BUILD_MAP now indicates an estimated
6025 dictionary size. There is a new opcode, STORE_MAP, for adding
6026 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006055- Patch #1739468: Directories and zipfiles containing a __main__.py
6056 file can now be directly executed by passing their name to the
6057 interpreter. The directory/zipfile is automatically inserted as the
6058 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006060- Issue #1265: Fix a problem with sys.settrace, if the tracing
6061 function uses a generator expression when at the same time the
6062 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006063
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006064- sets and frozensets now have an isdisjoint() method.
6065
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006066- optimize the performance of builtin.sum().

6069
Georg Brandl21e99f42010-03-07 15:23:59 +00006070- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006071 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6072 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006073
Georg Brandl3ee81df2008-05-17 18:14:43 +00006074- Issue #1686386: Tuple's tp_repr did not take into account the
6075 possibility of having a self-referential tuple, which is possible
6076 from C code. Nor did object's tp_str consider that a type's tp_str
6077 could do something that could lead to an inifinite recursion.
6078 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6079 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006080
Georg Brandl3ee81df2008-05-17 18:14:43 +00006081- Issue #1164: It was possible to trigger deadlock when using the
6082 'print' statement to write to a file since the GIL was not released
6083 as needed. Now PyObject_Print() does the right thing along with
6084 various tp_print implementations of the built-in types and those in
6085 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006086
Georg Brandl3ee81df2008-05-17 18:14:43 +00006087- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00006094- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006095 PyObject_Call() never calling back out to Python code to trigger
6096 recursion depth updates/checks. Required the creation of a static
6097 RuntimeError instance in case normalizing an exception put the
6098 recursion check value past its limit. Fixes crashers
6099 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006114- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006115 __*__ attributes. (Some already existed, e.g., __doc__ and
6116 __name__.)

6120
Georg Brandl2134e752007-05-21 20:34:16 +00006121- Patch #1686487: you can now pass any mapping after '**' in function
6122 calls.
6123
Collin Winter62903052007-05-18 23:11:24 +00006124- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006125 "except E as target:". This is to provide forwards compatibility
6126 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006133- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006134 setting a plain string, ie don't expand to single letter identifiers.
6135
Raymond Hettinger13936692007-04-11 18:40:58 +00006136- Request #1191699: Slices can now be pickled.
6137
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006138- Request #1193128: str.translate() now allows a None argument for

6140 remaining characters.
6141
Georg Brandl5cb76c12007-03-21 09:00:39 +00006142- Patch #1682205: a TypeError while unpacking an iterable is no longer

6146
Guido van Rossum143b5642007-03-23 04:58:42 +00006147- Bug #1683368: The object.__init__() and object.__new__() methods are
6148 now stricter in rejecting excess arguments. The only time when
6149 either allows excess arguments is when it is not overridden and the
6150 other one is. For backwards compatibility, when both are
6151 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006152 warning later). Also, type.__init__() insists on the same signature
6153 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006155- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6156 object to complex using its __complex__() method before falling back
6157 to the __float__() method. Therefore, the functions in the cmath
6158 module now can operate on objects that define a __complex__()
6159 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006181 its argument, if it exists. If not, it will work like before. This
6182 allows customizing the output of dir() in the presence of a
6183 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00006195- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00006265- Bug #1545497: when given an explicit base, int() did ignore NULs
6266 embedded in the string to convert.
6267
Georg Brandl846f73a2006-10-08 07:11:54 +00006268- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006316 generator expressions (x for x, in ... ) works again. Fixing this
6317 problem required changing the .pyc magic number. This means that
6318 .pyc files generated before 2.5c2 will be regenerated.

7126 with RFC 3207 and forgets any knowledge obtained from the server not
7127 obtained from the TLS negotiation itself. Patch contributed by Bill
7128 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007130- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007131 that the SMTP.starttls() caller no longer needs to call ehlo()
7132 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007133 does not claim to support starttls. Adds the
7134 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7135 Fenner.

7215 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7216 silently miscode subclasses of those types. Now, it raises a
7217 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007218

Georg Brandl3ee81df2008-05-17 18:14:43 +00007233 time so that opening a database previously created with the DB_DUP
7234 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7235 opens. Specifically: dictionary assignment to a DB object will
7236 replace all values for a given key when the database allows
7237 duplicate values. DB users should use DB.put(k, v) when they want
7238 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007239

7245 characters with ASCII value less than 32. Also, it correctly quotes
7246 dots only if they occur on a single line, as opposed to the previous
7247 behavior of quoting dots if they are the second character of any
7248 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007249
