1128
1129- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1130 and later systems as is currently done for Python 3.x installers.
1131 For 2.7.7 only, we will provide three installers:
1132 the legacy deprecated 10.3+ 32-bit-only format;
1133 the newer 10.5+ 32-bit-only format;
1134 and the unchanged 10.6+ 64-/32-bit format.
1135 Although binary installers will no longer be available from
1136 python.org as of 2.7.8, it will still be possible to build from
1137 source on 10.3.9 and 10.4 systems if necessary.
1138 See Mac/BuildScript/README.txt for more information.

2520 32-bit-only installer Pythons on systems with Xcode 4 (currently
2521 OS X 10.8, 10.7, and optionally 10.6).
2522 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2523 * Since Xcode 4 removes ppc support, extension module builds now
2524 check for ppc compiler support and by default remove ppc and
2525 ppc64 archs when they are not available.
2526 * Extension module builds now revert to using system installed
2527 headers and libs (/usr and /System/Library) if the SDK used
2528 to build the interpreter is not installed or has moved.
2529 * Try to avoid building extension modules with deprecated
2530 and problematic Apple llvm-gcc compiler. If original compiler
2531 is not available, use clang instead by default.

2976 Distutils-based packages with C extension modules may fail because
2977 Apple has removed gcc-4.2, the version used to build python.org
2978 64-bit/32-bit Pythons. If the user does not explicitly override
2979 the default C compiler by setting the CC environment variable,
2980 Distutils will now attempt to compile extension modules with clang
2981 if gcc-4.2 is required but not found. Also as a convenience, if
2982 the user does explicitly set CC, substitute its value as the default
2983 compiler in the Distutils LDSHARED configuration variable for OS X.

Ned Deily87e82bb2011-06-28 19:52:59 -07003236- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3237 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3238 interpreter process. This could cause failures in non-Distutils subprocesses
3239 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003240 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003241 deployment target only in the environment of each build subprocess. It is
3242 still possible to globally override the default by setting
3243 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3244 greater or equal to the default value, the value with which the interpreter
3245 was built.

3274 updating the check interval, so if the user decreases the check interval,
3275 the ticker doesn't have to wind down to zero from the old starting point
3276 before the new interval takes effect. And if the user increases the
3277 interval, it makes sure the new limit takes effect right away rather have an
3278 early task switch before recognizing the new interval.

4276 This prevents user-created self-referencing ordered dictionaries from
4277 becoming permanently uncollectable GC garbage. The downside is that

4736-----------------
4737
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004738- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4739 start byte and the continuation byte(s) are now considered invalid, instead
4740 of the number of bytes specified by the start byte.
4741 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4742 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4743 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4744 Previous versions returned a single u'\ufffd'.
4745
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004746- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00004747 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
4748 arises from the "Overriding __eq__ blocks inheritance ..." warning
4749 when turned into an exception: in this case the exception simply
4750 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004751
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004752- Issue #8748: Fix two issues with comparisons between complex and integer
4753 objects. (1) The comparison could incorrectly return True in some cases
4754 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4755 (2) The comparison raised an OverflowError for large integers, leading
4756 to unpredictable exceptions when combining integers and complex objects
4757 in sets or dicts.
4758
Mark Dickinson81336372010-05-30 12:12:25 +00004759- Issue #5211: Implicit coercion for the complex type is now completely
4760 removed. (Coercion for arithmetic operations was already removed in 2.7
4761 alpha 4, but coercion for rich comparisons was accidentally left in.)
4762
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004763- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
4764 and error handler, instead of writing to the C stderr file in utf-8
4765
Georg Brandlfee0f442010-05-22 21:26:21 +00004766- Issue #7902: When using explicit relative import syntax, don't try implicit
4767 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00004768
Georg Brandlfee0f442010-05-22 21:26:21 +00004769- Issue #7079: Fix a possible crash when closing a file object while using it
4770 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +00004771
Victor Stinnerb65bd2e2010-06-11 19:22:28 +00004772- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00004773 Window Server again in a framework build on MacOSX 10.5 or earlier.

4777
Georg Brandlfee0f442010-05-22 21:26:21 +00004778- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
4779 of the interpreter to set sys.argv without also modifying sys.path. This
4780 helps fix `CVE-2008-5983

4805
R. David Murray52dcd452010-06-02 22:03:15 +00004806- Issue #1368247: set_charset (and therefore MIMEText) now automatically

4897 non-float non-integer argument is now converted to an integer (if possible)
4898 using its __int__ method. Previously, only small arguments were treated this

5127 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00005139- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5140 with a non-empty format string. This is an effort to future-proof user
5141 code. If a derived class does not currently implement __format__ but later
5142 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005143 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005144 Python 3.3 and it will be an error in Python 3.4.

5582 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5583 returning NULL. The macro now returns a statically allocated empty string

5594 strings,
5595 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5596 numeric strings corresponding to subnormal values,
5597 (3) a memory leak for some values large enough to cause overflow, and
5598 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00005629- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005630 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00005631 Also, raise ValueError rather than TypeError when an unknown TIPC address

Georg Brandlba83f822010-03-14 09:50:54 +00005637 file position when calling `truncate()`. It would previously change the file
5638 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005639 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5640

5642 class used to represent files stored inside an archive. The new
5643 implementation is significantly faster and can be wrapped in a
5644 ``io.BufferedReader`` object for more speedups. It also solves an issue
5645 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00005656- Issue #7748: Since unicode values are supported for some metadata options in
5657 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5658 encoded string for them. This ensures that the upload and register commands
5659 send the correct values to PyPI without any error.

5734-----------------
5735
Georg Brandlba83f822010-03-14 09:50:54 +00005736- The ``__complex__()`` method is now looked up on the class of instances to
5737 make it consistent with other special methods.

5741
Mark Dickinson1b34d252010-01-01 17:27:30 +00005742- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005743 DeprecationWarning when passed a float argument where an integer was expected.
5744 These functions and methods now raise TypeError instead. The majority of the
5745 effects of this change are in the extension modules, but some core functions
5746 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5747 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00005760- Issue #1811: Improve accuracy and cross-platform consistency for true division
5761 of integers: the result of a/b is now correctly rounded for ints a and b (at
5762 least on IEEE 754 platforms), and in particular does not depend on the
5763 internal representation of a long.

5771
Georg Brandlba83f822010-03-14 09:50:54 +00005772 These executables now work properly with the arch(1) command: ``arch -ppc
5773 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005929- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5930 decimal string that's guaranteed to round back to x under correct rounding
5931 (with round-half-to-even rounding mode). Previously it gave a string based on
5932 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5933 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5934 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00005936- Issue #7117: On almost all platforms: float-to-string and string-to-float
5937 conversions within Python are now correctly rounded. Places these conversions
5938 occur include: str for floats and complex numbers; the float and complex
5939 constructors; old-style and new-style numeric formatting; serialization and
5940 deserialization of floats and complex numbers using marshal, pickle and json;
5941 parsing of float and imaginary literals in Python code; Decimal-to-float
5942 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005943
Georg Brandlba83f822010-03-14 09:50:54 +00005944 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5945 providing correctly-rounded strtod and dtoa C functions. This code is
5946 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5947 the C compiler. There may be a small number of platforms on which correct
5948 operation of this code cannot be guaranteed, so the code is not used: notably,
5949 this applies to platforms where the C double format is not IEEE 754 binary64,
5950 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5951 and Python's configure script is unable to determine how to change the FPU
5952 precision. On these platforms conversions use the platform strtod and dtoa,
5953 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005955- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5956 uses the correctly-rounded string <-> float conversions described above (when
5957 available), and so produces correctly rounded results that will display nicely
5958 under the float repr. There are two related small changes: (1) round now
5959 accepts any class with an ``__index__()`` method for its second argument (but
5960 no longer accepts floats for the second argument), and (2) an excessively
5961 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5962 raises an exception.

7569 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7570 neither __int__ nor __long__, TypeError used to be raised (with a
7571 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
7572 struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007769- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7771 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7772 ``printf`` function, whereas PyString_FromFormat has an independent
7773 implementation and uses "%zd" on all platforms for size_t values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007790- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007791 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007792 was correctly parsed but parsing of subsequent arguments failed.
7793
Vinay Sajip35e3b032008-09-01 14:33:59 +00007794- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007795 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7796 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7797 when given a tuple of classes as second argument, were looking up
7798 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7799 type object.
7800
Neal Norwitz18aa3882008-08-24 05:04:52 +00007801- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007870 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7871 for catch_warnings() also led to an improvement in the raising of a
7872 DeprecationWarning related to warnings.warn_explicit().
7873

7900
Benjamin Peterson37346b22008-08-23 20:27:43 +00007901- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007938What's New in Python 2.6 beta 3?
7939================================
7940
Barry Warsaw07a4a382008-08-21 01:15:08 +00007941*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007942
7943Core and Builtins
7944-----------------
7945
Guido van Rossumf8402962008-08-20 15:01:50 +00007946- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7947 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7948 extensions do not automatically benefit from the class attribute
7949 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7950 to their tp_flags field if they care. This is a backwards
7951 compatibility feature; in 3.0, all types will use the cache by
7952 default.
7953
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007954- Keyword arguments can now follow starred arguments. (``f(a, *args,
7955 keyword=23)`` is now valid syntax.)
7956
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007957- ctypes function pointers that are COM methods have a boolean True
7958 value again.
7959
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007960- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7961 by denying s# to parse objects that have a releasebuffer procedure,
7962 and introducing s*.
7963
Georg Brandl1e13ea92008-08-11 09:07:59 +00007964- Issue #3537: Fix an assertion failure when an empty but presized dict
7965 object was stored in the freelist.
7966
Mark Dickinsonb6467572008-08-04 21:30:09 +00007967- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7968 ValueError consistently across platforms.
7969
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007970- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7971 (64bit Unix, for example), unichr() would truncate its argument and return
7972 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7973
Neal Norwitze7d8be82008-07-31 17:17:14 +00007974- Apply security patches from Apple.
7975
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007976- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7977 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7978
Antoine Pitrou92f82162008-07-25 22:22:08 +00007979- Issue #1819: function calls with several named parameters are now on
7980 average 35% faster (as measured by pybench).
7981
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007982- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7983 the python debugger steps into a class statement: the free variables (local
7984 variables defined in an outer scope) would be deleted from the outer scope.
7985
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007986- Issue #2620: Overflow checking when allocating or reallocating memory
7987 was not always being done properly in some python types and extension
7988 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7989 all been updated to perform better checks and places in the code that
7990 would previously leak memory on the error path when such an allocation
7991 failed have been fixed.

7994-------
7995
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007996- Issue #3612: Added some missing basic types in ctypes.wintypes.
7997
Benjamin Petersone977ad42008-08-20 01:42:01 +00007998- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7999 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8000
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008001- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8002 version reported by these tools does not necessarily follow the python
8003 version numbering scheme, so the module is less strict when parsing it.
8004
Nick Coghlanf70385a2008-08-18 12:42:46 +00008005- Issue #2235: Added Py3k warnings for types which will become unhashable
8006 under the stricter __hash__ inheritance rules in 3.0. Several types
8007 which did not meet the rules for hash invariants and were already
8008 unhashable in 3.0 have now been explicitly flagged as unhashable in
8009 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8010 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8011
Brett Cannon88f801d2008-08-18 00:46:22 +00008012- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8013 imported into the module but exposed as part of the module's API.
8014
Brett Cannon7b96f072008-08-18 00:41:11 +00008015- Remove an unneeded import of abc.ABCMeta from 'inspect'.
8016
Brett Cannon46225e72008-08-18 00:36:52 +00008017- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00008019- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
8020
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008021- Issue #3575: Incremental decoder's decode function now takes bytearray
8022 by using 's*' instead of 't#'.
8023
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008024- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008025 fails unicode conversion on 2nd parameter. (windows only)
8026
Georg Brandl222e2082010-08-01 22:27:39 +00008027- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008028 in a redirect.
8029
Brett Cannonabe423e2008-08-16 21:47:07 +00008030- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00008031 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008032
Facundo Batistaeb90b782008-08-16 14:44:07 +00008033- Issue #2776: fixed small issue when handling an URL with double slash
8034 after a 302 response in the case of not going through a proxy.
8035
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008036- Issue #2676: in the email package, content-type parsing was hanging on
8037 pathological input because of quadratic or exponential behaviour of a
8038 regular expression.
8039
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008040- Issue #3476: binary buffered reading through the new "io" library is now
8041 thread-safe.
8042
Brett Cannonbf3157b2008-08-14 05:00:03 +00008043- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8044 since mimetools itself is deprecated. Because modules are cached, all
8045 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8046
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008047- Issue #3134: shutil referenced undefined WindowsError symbol.
8048
Robert Schuppenies14646332008-08-10 11:01:53 +00008049- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8050 menu entries were not deleted.
8051
Brett Cannon83e81842008-08-09 23:30:55 +00008052- Copied the implementation of reduce() to _functools.reduce() to have a
8053 version that did not raise a DeprecationWarning under -3.
8054
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008055- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8056 a MemoryError rather than silently stop the iteration.
8057
Guido van Rossum59ce9012008-08-09 14:55:34 +00008058- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8059 to _sre.compile() will now be rejected. This should not affect anybody
8060 since the re.compile() function never generates invalid re-bytecode.
8061
Skip Montanaroa032bf42008-08-08 22:52:51 +00008062- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8063 upon first access it can be automatically initialized from the csv file if
8064 it wasn't initialized during instantiation.
8065
Brett Cannon3aa2a492008-08-06 22:28:09 +00008066- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8067 the reload() built-in has been removed.
8068
Brett Cannon7e30b672008-08-04 21:52:25 +00008069- Changed code in the following modules/packages to remove warnings raised

8138-----------------
8139
Georg Brandl3e483f62008-07-16 22:57:41 +00008140- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8141 its methods now allow for items objects that can be converted to
8142 an integer using operator.index().
8143
Mark Dickinson64b7e502008-07-16 09:40:03 +00008144- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8145 produced a ValueError instead of giving the correct float.
8146
Eric Smitha5fa5a22008-07-16 00:11:49 +00008147- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8148 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8149
Mark Dickinson7103aa42008-07-15 19:08:33 +00008150- Issue #3008: the float type has a new instance method 'float.hex'
8151 and a new class method 'float.fromhex' to convert floating-point
8152 numbers to and from hexadecimal strings, respectively.
8153
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008154- Issue #2235: __hash__ is once again inherited by default. To allow
8155 collections.Hashable to remain meaningful in the presence of the
8156 default hash implementation (object.__hash__), it is now possible
8157 to explicit block inheritance of hash by setting __hash__=None at
8158 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8159 level.
8160
Nick Coghlanb028f502008-07-13 14:52:36 +00008161- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8162 the parent module cannot be found while performing an absolute import.
8163 This means that an incorrectly defined __package__ attribute will
8164 now only prevent relative imports in that module rather than causing
8165 all imports from that module to fail.
8166
Nick Coghlan14ff9942008-07-08 14:21:42 +00008167- Issue #2517: Allow unicode messages in Exceptions again by correctly

8177 another thread's dictionary.
8178
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008179- Issue #3004: Minor change to slice.indices(): the start and stop
8180 arguments are now treated identically, making the behaviour easier
8181 to describe and understand. For example, slice(None, -10,
8182 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8183 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8184 10, -1).

8227 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008228 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008229 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008245- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00008636 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008637
8638 This is controlled by the configure argument ``--with-universal-archs``:
8639
8640 - ``--with-universal-archs=all``: install 4-way universal
8641
8642 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8643
8644 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8645
8646 This option should be used in combination with ``--enable-universalsdk=``.
8647
8648 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

8652
Georg Brandl74a1dea2008-05-28 11:21:39 +00008653- Add ``PyType_Modified()`` as a public API to clear the type cache.
8654
8655- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00008656
8657- The PyString functions have been renamed to PyBytes. A batch of
8658 defines were added so that the linker still sees the original
8659 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008697- Issue #1631171: Re-implement the 'warnings' module in C (the
8698 original Python code has been kept as backup). This will allow for
8699 using the 'warning's machinery in such places as the parser where
8700 use of pure Python code is not possible. Both the ``showarning()``
8701 and ``formatwarning()`` gain an optional 'line' argument which is
8702 not called by default for backwards-compatibility reasons. Setting
8703 ``warnings.showwarning()`` to an implementation that lacks support
8704 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008746- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008747 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00008767- Issue #2550: The approach used by client/server code for obtaining
8768 ports to listen on in network-oriented tests has been refined in an
8769 effort to facilitate running multiple instances of the entire
8770 regression test suite in parallel without issue.
8771 test_support.bind_port() has been fixed such that it will always
8772 return a unique port -- which wasn't always the case with the
8773 previous implementation, especially if socket options had been set
8774 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8775 new implementation of bind_port() will actually raise an exception
8776 if it is passed an AF_INET/SOCK_STREAM socket with either the
8777 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8778 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8779 the socket it's been passed. This currently only applies to
8780 Windows. This option prevents any other sockets from binding to the
8781 host/port we've bound to, thus removing the possibility of the
8782 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8783 when a second SOCK_STREAM socket binds and accepts to a host/port
8784 that's already been bound by another socket. The optional preferred
8785 port parameter to bind_port() has been removed. Under no
8786 circumstances should tests be hard coding ports!
8787
8788 test_support.find_unused_port() has also been introduced, which will
8789 pass a temporary socket object to bind_port() in order to obtain an
8790 unused port. The temporary socket object is then closed and
8791 deleted, and the port is returned. This method should only be used
8792 for obtaining an unused port in order to pass to an external program
8793 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8794 a parameter to a server-oriented class that doesn't give you direct
8795 access to the underlying socket used.
8796
8797 Finally, test_support.HOST has been introduced, which should be used
8798 for the host argument of any relevant socket calls (i.e. bind and
8799 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008800
8801 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008802 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008803 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8804 test_asynchat and test_socket_ssl.
8805
Georg Brandl3ee81df2008-05-17 18:14:43 +00008806 It is now possible for multiple instances of the regression test
8807 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009086- Added the future_builtins module, which contains hex() and oct().
9087 These are the PEP 3127 version of these functions, designed to be
9088 compatible with the hex() and oct() builtins from Python 3.0. They
9089 differ slightly in their output formats from the existing, unchanged
9090 Python 2.6 builtins. The expected usage of the future_builtins
9091 module is:
9092 from future_builtins import hex, oct
9093
Eric Smith7ef40bf2008-02-20 23:34:22 +00009094- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9095 exponents for exponents with absolute value < 100. Follows C99
9096 standard. This is a change on Windows, which would use 3 digits.
9097 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9098 so that any alterations it does to the resulting string will be
9099 available in stringlib/formatter.h (for float.__format__).
9100
Eric Smith5a3c1352008-02-19 13:21:56 +00009101- Implemented PEP 3101, Advanced String Formatting. This adds a new
9102 builtin format(); a format() method for str and unicode; a
9103 __format__() method to object, str, unicode, int, long, float, and
9104 datetime; the class string.Formatter; and the C API
9105 PyObject_Format().
9106
Georg Brandl3ee81df2008-05-17 18:14:43 +00009107- Fixed several potential crashes, all caused by specially crafted
9108 __del__ methods exploiting objects in temporarily inconsistent
9109 state.

9120 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009121
Georg Brandl3ee81df2008-05-17 18:14:43 +00009122- Issue #2045: Fix an infinite recursion triggered when printing a
9123 subclass of collections.defaultdict, if its default_factory is set
9124 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009125
Christian Heimesf75dbef2008-02-08 00:11:31 +00009126- Fixed a minor memory leak in dictobject.c. The content of the free

9135
Georg Brandl3ee81df2008-05-17 18:14:43 +00009136- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

Georg Brandl3ee81df2008-05-17 18:14:43 +00009152- Patch #1473257: generator objects gain a gi_code attribute. This is
9153 the same object as the func_code attribute of the function that
9154 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009155
Georg Brandl3ee81df2008-05-17 18:14:43 +00009156- Issue #1920: "while 0" statements were completely removed by the
9157 compiler, even in the presence of an "else" clause, which is
9158 supposed to be run when the condition is false. Now the compiler
9159 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009160
Guido van Rossumeead05f2008-01-24 18:21:02 +00009161- A few crashers fixed: weakref_in_del.py (issue #1377858);
9162 loosing_dict_ref.py (issue #1303614, test67.py);
9163 borrowed_ref_[34].py (not in tracker).
9164
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009165- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009166 suppressed while an extension is loaded by calling SetErrorMode in
9167 dynload_win.c. The error is still reported properly.
9168
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009170 several extension methods and modules do not work without unicode
9171 support.
9172
Georg Brandl26543b12008-01-21 18:36:51 +00009173- Issue #1882: when compiling code from a string, encoding cookies in the
9174 second line of code were not always recognized correctly.
9175
Georg Brandl14404b62008-01-19 19:27:05 +00009176- Issue #1679: "0x" was taken as a valid integer literal.
9177
Georg Brandl6caad7d2008-01-26 14:19:22 +00009178- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009179 added.
9180
Christian Heimesc94e2b52008-01-14 04:13:37 +00009181- sys.float_info / PyFloat_GetInfo: The floating point information
9182 object was converted from a dict to a specialized structseq object.
9183
Georg Brandl3ee81df2008-05-17 18:14:43 +00009184- Patch #1816: Added sys.flags structseq. It exposes the status of
9185 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009186
Georg Brandl3ee81df2008-05-17 18:14:43 +00009187- Objects/structseq.c: Implemented new structseq representation. The
9188 patch makes structseqs (e.g. the return value of os.stat) more
9189 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009190
Georg Brandl3ee81df2008-05-17 18:14:43 +00009191- Patch #1700288: added a type attribute cache that caches method
9192 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009193
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009194- Bug #1776: __import__() no longer accepts filenames on any platform.
9195 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009196
Georg Brandlaed6c662008-01-07 17:25:53 +00009197- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9198
Georg Brandl3ee81df2008-05-17 18:14:43 +00009199- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9200 envvar and sys.dont_write_bytecode attribute. All these can be set
9201 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009202
Georg Brandl3ee81df2008-05-17 18:14:43 +00009203- Improve some exception messages when Windows fails to load an
9204 extension module. Now we get for example '%1 is not a valid Win32
9205 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009206
Georg Brandl3ee81df2008-05-17 18:14:43 +00009207- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009209- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9210 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009211
Christian Heimes0a8143f2007-12-18 23:22:54 +00009212- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009213 and INF. float("nan"), float("inf") and float("-inf") now work on
9214 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009215
Georg Brandl3ee81df2008-05-17 18:14:43 +00009216- Compiler now generates simpler and faster code for dictionary
9217 literals. The oparg for BUILD_MAP now indicates an estimated
9218 dictionary size. There is a new opcode, STORE_MAP, for adding
9219 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009220
Georg Brandl3ee81df2008-05-17 18:14:43 +00009221- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009226- Issue #1538: Avoid copying string in split/rsplit if the split char
9227 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009228
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009229- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009230 SystemError.
9231
Nick Coghlanef01d822007-12-03 12:55:17 +00009232- PEP 366: Allow explicit relative imports when executing modules
9233 inside packages with the -m switch via a new module level
9234 __package__ attribute.
9235
Georg Brandl3ee81df2008-05-17 18:14:43 +00009236- Issue #1402: Fix a crash on exit, when another thread is still
9237 running, and if the deallocation of its frames somehow calls the
9238 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009239

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00009243 attribute of an empty cell object.
9244
Georg Brandl3ee81df2008-05-17 18:14:43 +00009245- Issue #1460: The utf-7 incremental decoder did not accept truncated
9246 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00009247
Georg Brandl3ee81df2008-05-17 18:14:43 +00009248- Patch #1739468: Directories and zipfiles containing a __main__.py
9249 file can now be directly executed by passing their name to the
9250 interpreter. The directory/zipfile is automatically inserted as the
9251 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009252
Georg Brandl3ee81df2008-05-17 18:14:43 +00009253- Issue #1265: Fix a problem with sys.settrace, if the tracing
9254 function uses a generator expression when at the same time the
9255 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009256
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009257- sets and frozensets now have an isdisjoint() method.
9258
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009259- optimize the performance of builtin.sum().
9260
Neal Norwitz44f326e2007-10-05 05:29:17 +00009261- Fix warnings found by the new version of the Coverity checker.
9262
Georg Brandl21e99f42010-03-07 15:23:59 +00009263- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009264 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9265 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009266
Georg Brandl3ee81df2008-05-17 18:14:43 +00009267- Issue #1686386: Tuple's tp_repr did not take into account the
9268 possibility of having a self-referential tuple, which is possible
9269 from C code. Nor did object's tp_str consider that a type's tp_str
9270 could do something that could lead to an inifinite recursion.
9271 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9272 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009273
Georg Brandl3ee81df2008-05-17 18:14:43 +00009274- Issue #1164: It was possible to trigger deadlock when using the
9275 'print' statement to write to a file since the GIL was not released
9276 as needed. Now PyObject_Print() does the right thing along with
9277 various tp_print implementations of the built-in types and those in
9278 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009279
Georg Brandl3ee81df2008-05-17 18:14:43 +00009280- Issue #1147: Exceptions were directly allowing string exceptions in
9281 their throw() method even though string exceptions no longer
9282 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009283
Georg Brandl3ee81df2008-05-17 18:14:43 +00009284- Issue #1096: Prevent a segfault from getting the repr of a very
9285 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009286
Brett Cannon1e534b52007-09-07 04:18:30 +00009287- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009288 PyObject_Call() never calling back out to Python code to trigger
9289 recursion depth updates/checks. Required the creation of a static
9290 RuntimeError instance in case normalizing an exception put the
9291 recursion check value past its limit. Fixes crashers
9292 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009293
Georg Brandl3ee81df2008-05-17 18:14:43 +00009294- Patch #1031213: Decode source line in SyntaxErrors back to its

9298 with %G.
9299
Georg Brandl3ee81df2008-05-17 18:14:43 +00009300- Prevent expandtabs() on string and unicode objects from causing a
9301 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00009302

Neal Norwitz0ac60192007-05-27 04:08:54 +00009307- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009308 __*__ attributes. (Some already existed, e.g., __doc__ and
9309 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009310
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009311- Add -3 option to the interpreter to warn about features that are
9312 deprecated and will be changed/removed in Python 3.0.
9313
Georg Brandl2134e752007-05-21 20:34:16 +00009314- Patch #1686487: you can now pass any mapping after '**' in function
9315 calls.
9316
Collin Winter62903052007-05-18 23:11:24 +00009317- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009318 "except E as target:". This is to provide forwards compatibility
9319 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009320
Brett Cannon229cee22007-05-05 01:34:02 +00009321- Deprecate BaseException.message as per PEP 352.
9322
Georg Brandl3ee81df2008-05-17 18:14:43 +00009323- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009324 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009325
Vinay Sajip8549ce32007-05-06 17:53:37 +00009326- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009327 setting a plain string, ie don't expand to single letter identifiers.
9328
Raymond Hettinger13936692007-04-11 18:40:58 +00009329- Request #1191699: Slices can now be pickled.
9330
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009331- Request #1193128: str.translate() now allows a None argument for
9332 translations that only remove characters without re-mapping the
9333 remaining characters.
9334
Georg Brandl5cb76c12007-03-21 09:00:39 +00009335- Patch #1682205: a TypeError while unpacking an iterable is no longer
9336 masked by a generic one with the message "unpack non-sequence".
9337
Neal Norwitzaa754b72007-03-21 06:39:48 +00009338- Remove unused file Python/fmod.c.
9339
Guido van Rossum143b5642007-03-23 04:58:42 +00009340- Bug #1683368: The object.__init__() and object.__new__() methods are
9341 now stricter in rejecting excess arguments. The only time when
9342 either allows excess arguments is when it is not overridden and the
9343 other one is. For backwards compatibility, when both are
9344 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009345 warning later). Also, type.__init__() insists on the same signature
9346 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009347
Georg Brandl3ee81df2008-05-17 18:14:43 +00009348- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9349 object to complex using its __complex__() method before falling back
9350 to the __float__() method. Therefore, the functions in the cmath
9351 module now can operate on objects that define a __complex__()
9352 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009353
Georg Brandl3ee81df2008-05-17 18:14:43 +00009354- Patch #1623563: allow __class__ assignment for classes with
9355 __slots__. The old and the new class are still required to have the
9356 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009357
Georg Brandl3ee81df2008-05-17 18:14:43 +00009358- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00009361- Patch #1462488: Python no longer segfaults when
9362 ``object.__reduce_ex__()`` is called with an object that is faking
9363 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009364
Georg Brandl3ee81df2008-05-17 18:14:43 +00009365- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00009368- Patch #1444529: the builtin compile() now accepts keyword arguments.
9369
Georg Brandl7b9c5552007-03-12 14:30:05 +00009370- Bug #1678647: write a newline after printing an exception in any
9371 case, even when converting the value to a string failed.
9372
Georg Brandl871f1bc2007-03-12 13:17:36 +00009373- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009374 its argument, if it exists. If not, it will work like before. This
9375 allows customizing the output of dir() in the presence of a
9376 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009377
Collin Winter276887b2007-03-12 16:11:39 +00009378- Patch #922167: Python no longer segfaults when faced with infinitely
9379 self-recursive reload() calls (as reported by bug #742342).
9380
Georg Brandl3ee81df2008-05-17 18:14:43 +00009381- Patch #1675981: remove unreachable code from ``type.__new__()``
9382 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00009383
Georg Brandl3ee81df2008-05-17 18:14:43 +00009384- Patch #1491866: change the complex() constructor to allow
9385 parthensized forms. This means complex(repr(x)) now works instead of
9386 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009387
Georg Brandlaa2321b2007-03-07 00:40:28 +00009388- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009389 makes the filenames the warning module prints much more sensible

Facundo Batistad918a652007-04-24 13:54:38 +00009898- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009899 the client's request was successfully received, understood, and
9900 accepted. Now in these cases no error is raised in urllib (issue
9901 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00009902

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009909- Added a timeout parameter to the constructor of other protocols
9910 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9911 work started with create_connection() and timeout in httplib, and
9912 closes patch #723312.
9913
Vinay Sajip8549ce32007-05-06 17:53:37 +00009914- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00009940 AttributeError instead of an IOError when the server's response
9941 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009942
Georg Brandl3ee81df2008-05-17 18:14:43 +00009943- Patch #957650: "%var%" environment variable references are now
9944 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00009946
Georg Brandl3ee81df2008-05-17 18:14:43 +00009947- Patch #1429539: pdb now correctly initializes the __main__ module
9948 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009949 correctly now.
9950

9957
Georg Brandl3ee81df2008-05-17 18:14:43 +00009958- Patch #1530482: add pydoc.render_doc() which returns the
9959 documentation for a thing instead of paging it to stdout, which
9960 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00009961

9973
Georg Brandl92a6bae2007-03-13 17:43:32 +00009974- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009975 are set for invalid interpolation sequences that would lead to
9976 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00009977

10019 returned string up to the first NUL character.
10020

10030
Georg Brandl3ee81df2008-05-17 18:14:43 +000010031- unittest now verifies more of its assumptions. In particular,
10032 TestCase and TestSuite subclasses (not instances) are no longer
10033 accepted in TestSuite.addTest(). This should cause no

10035 -- the failure just occurred later, with a more cumbersome
10036 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010419 time so that opening a database previously created with the DB_DUP
10420 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10421 opens. Specifically: dictionary assignment to a DB object will
10422 replace all values for a given key when the database allows
10423 duplicate values. DB users should use DB.put(k, v) when they want
10424 to store duplicates; not DB[k] = v.

10431 characters with ASCII value less than 32. Also, it correctly quotes
10432 dots only if they occur on a single line, as opposed to the previous
10433 behavior of quoting dots if they are the second character of any
10434 line.
