Victor Stinner66c6e9d2013-12-13 02:37:09 +0100704- Issue #14432: Generator now clears the borrowed reference to the thread
705 state. Fix a crash when a generator is created in a C thread that is
706 destroyed while the generator is still used. The issue was that a generator
707 contains a frame, and the frame kept a reference to the Python state of the
708 destroyed C thread. The crash occurs when a trace function is setup.

1113
1114- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1115 and later systems as is currently done for Python 3.x installers.
1116 For 2.7.7 only, we will provide three installers:
1117 the legacy deprecated 10.3+ 32-bit-only format;
1118 the newer 10.5+ 32-bit-only format;
1119 and the unchanged 10.6+ 64-/32-bit format.
1120 Although binary installers will no longer be available from
1121 python.org as of 2.7.8, it will still be possible to build from
1122 source on 10.3.9 and 10.4 systems if necessary.
1123 See Mac/BuildScript/README.txt for more information.

2504 In particular, fix extension module build failures when trying to use
2505 32-bit-only installer Pythons on systems with Xcode 4 (currently
2506 OS X 10.8, 10.7, and optionally 10.6).
2507 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2508 * Since Xcode 4 removes ppc support, extension module builds now
2509 check for ppc compiler support and by default remove ppc and
2510 ppc64 archs when they are not available.
2511 * Extension module builds now revert to using system installed
2512 headers and libs (/usr and /System/Library) if the SDK used
2513 to build the interpreter is not installed or has moved.
2514 * Try to avoid building extension modules with deprecated
2515 and problematic Apple llvm-gcc compiler. If original compiler
2516 is not available, use clang instead by default.

2884 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01002960- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2961 Distutils-based packages with C extension modules may fail because
2962 Apple has removed gcc-4.2, the version used to build python.org
2963 64-bit/32-bit Pythons. If the user does not explicitly override
2964 the default C compiler by setting the CC environment variable,
2965 Distutils will now attempt to compile extension modules with clang
2966 if gcc-4.2 is required but not found. Also as a convenience, if
2967 the user does explicitly set CC, substitute its value as the default
2968 compiler in the Distutils LDSHARED configuration variable for OS X.
2969 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2970 SDK, neither of which are available in Xcode 4. This change does not
2971 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003221- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3222 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3223 interpreter process. This could cause failures in non-Distutils subprocesses
3224 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003225 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003226 deployment target only in the environment of each build subprocess. It is
3227 still possible to globally override the default by setting
3228 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3229 greater or equal to the default value, the value with which the interpreter
3230 was built.

3260 the ticker doesn't have to wind down to zero from the old starting point
3261 before the new interval takes effect. And if the user increases the
3262 interval, it makes sure the new limit takes effect right away rather have an
3263 early task switch before recognizing the new interval.

4250 by Andrew Bennetts.

4259
Raymond Hettinger20397532010-09-12 02:11:45 +00004260- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4261 This prevents user-created self-referencing ordered dictionaries from
4262 becoming permanently uncollectable GC garbage. The downside is that
4263 removing __del__ means that the internal doubly-linked list has to wait for
4264 GC collection rather than freeing memory immediately when the refcnt drops
4265 to zero.
4266
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004267- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

4270
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004271- Issue #9792: In case of connection failure, socket.create_connection()
4272 would swallow the exception and raise a new one, making it impossible
4273 to fetch the original errno, or to filter timeout errors. Now the
4274 original error is re-raised.
4275
Antoine Pitrouf4f61712010-09-07 16:34:47 +00004276- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
4277 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
4278 be updated back after the system call. Original patch by Brian Brazil.

4285
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00004286- Issue #808164: Fixed socket.close to avoid references to globals, to
4287 avoid issues when socket.close is called from a __del__ method.
4288
Terry Reedyd2d2ae92010-11-11 23:22:19 +00004289- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
4290 can be set to False to turn off the previously undocumented 'popularity'
4291 heuristic. Patch by Terry Reedy and Eli Bendersky
4292
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00004293- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
4294 falling into recursion.
4295
R. David Murray7c4bf552010-08-25 01:45:57 +00004296- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4297 character years even if the message contains RFC822 two character years.
4298
Daniel Stutzbach91287322010-08-24 21:09:30 +00004299- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00004310- Issue #9214: Set operations on KeysView or ItemsView in the collections
4311 module now correctly return a set. (Patch by Eli Bendersky.)
4312
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00004313- Issue #9617: Signals received during a low-level write operation aren't
4314 ignored by the buffered IO layer anymore.
4315
Benjamin Peterson52c36052010-08-21 03:03:22 +00004316- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
4317 are not held onto after they are deleted elsewhere.
4318
Raymond Hettingera54b2da2010-08-17 19:03:06 +00004319- Issue #9626: the view methods for collections.OrderedDict() were returning
4320 the unordered versions inherited from dict. Those methods are now
4321 overridden to provide ordered views.
4322
Éric Araujo0389ae62010-08-14 03:07:46 +00004323- Issue #8688: MANIFEST files created by distutils now include a magic
4324 comment indicating they are generated. Manually maintained MANIFESTs
4325 without this marker will not be overwritten or removed.
4326
Antoine Pitroue1436d12010-08-12 15:25:51 +00004327- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
4328 and a BadZipfile error is raised if it doesn't match (as used to be the
4329 case in Python 2.5 and earlier).
4330
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00004331- Issue #9550: a BufferedReader could issue an additional read when the
4332 original read request had been satisfied, which could block indefinitely
4333 when the underlying raw IO channel was e.g. a socket. Report and original
4334 patch by Jason V. Miller.
4335
Fred Drake0a1fa0e2010-08-10 13:09:54 +00004336- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00004354- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
4355 This is how it is supposed to work, wget and curl do the same. Previous
4356 behavior was wrong.

4364 the option character for the added 'h/help' option if prefix_chars
4365 does not contain a '-', instead of raising an error.
4366

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004737- Issue #8748: Fix two issues with comparisons between complex and integer
4738 objects. (1) The comparison could incorrectly return True in some cases
4739 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4740 (2) The comparison raised an OverflowError for large integers, leading
4741 to unpredictable exceptions when combining integers and complex objects
4742 in sets or dicts.

4989 indefinitely if the other end didn't respond.
4990
Georg Brandlfee0f442010-05-22 21:26:21 +00004991- The do_handshake() method of SSL objects now adjusts the blocking mode of the

5110
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005111- Issue #8329: Don't return the same lists from select.select when no fds are
5112 changed.
5113
Georg Brandlfee0f442010-05-22 21:26:21 +00005114- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005115 on 64-bit machines. The shift count for either left or right shift is
5116 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00005124- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5125 with a non-empty format string. This is an effort to future-proof user
5126 code. If a derived class does not currently implement __format__ but later
5127 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005128 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005129 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00005162- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00005179- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5180 InvalidOperation instead of returning False. (Comparisons involving a quiet
5181 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5182 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005183
Georg Brandlfee0f442010-05-22 21:26:21 +00005184- Issue #2531: Comparison operations between floats and Decimal instances now
5185 return a result based on the numeric values of the operands; previously they
5186 returned an arbitrary result based on the relative ordering of id(float) and
5187 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00005201- Comparisons using one of <, <=, >, >= between a complex instance and a
5202 Fractions instance now raise TypeError instead of returning True/False. This
5203 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5204 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00005622 file position when calling `truncate()`. It would previously change the file
5623 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005624 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

5627 class used to represent files stored inside an archive. The new
5628 implementation is significantly faster and can be wrapped in a

5630 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5720
Georg Brandlba83f822010-03-14 09:50:54 +00005721- The ``__complex__()`` method is now looked up on the class of instances to
5722 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005723
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005724- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5725 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5726
Mark Dickinson1b34d252010-01-01 17:27:30 +00005727- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005728 DeprecationWarning when passed a float argument where an integer was expected.
5729 These functions and methods now raise TypeError instead. The majority of the
5730 effects of this change are in the extension modules, but some core functions
5731 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5732 and many unicode/str methods.

5744
Georg Brandlba83f822010-03-14 09:50:54 +00005745- Issue #1811: Improve accuracy and cross-platform consistency for true division
5746 of integers: the result of a/b is now correctly rounded for ints a and b (at
5747 least on IEEE 754 platforms), and in particular does not depend on the
5748 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00005750- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00005755 executables on OSX.
5756
Georg Brandlba83f822010-03-14 09:50:54 +00005757 These executables now work properly with the arch(1) command: ``arch -ppc
5758 python`` will start a universal binary version of python in PPC mode (unlike
5759 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00005781 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00005921- Issue #7117: On almost all platforms: float-to-string and string-to-float
5922 conversions within Python are now correctly rounded. Places these conversions
5923 occur include: str for floats and complex numbers; the float and complex
5924 constructors; old-style and new-style numeric formatting; serialization and
5925 deserialization of floats and complex numbers using marshal, pickle and json;
5926 parsing of float and imaginary literals in Python code; Decimal-to-float
5927 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005928
Georg Brandlba83f822010-03-14 09:50:54 +00005929 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5930 providing correctly-rounded strtod and dtoa C functions. This code is
5931 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5932 the C compiler. There may be a small number of platforms on which correct
5933 operation of this code cannot be guaranteed, so the code is not used: notably,
5934 this applies to platforms where the C double format is not IEEE 754 binary64,
5935 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5936 and Python's configure script is unable to determine how to change the FPU
5937 precision. On these platforms conversions use the platform strtod and dtoa,
5938 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005940- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5941 uses the correctly-rounded string <-> float conversions described above (when
5942 available), and so produces correctly rounded results that will display nicely
5943 under the float repr. There are two related small changes: (1) round now
5944 accepts any class with an ``__index__()`` method for its second argument (but
5945 no longer accepts floats for the second argument), and (2) an excessively
5946 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5947 raises an exception.

7756 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7757 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00007855 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7856 for catch_warnings() also led to an improvement in the raising of a
7857 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007923What's New in Python 2.6 beta 3?
7924================================
7925
Barry Warsaw07a4a382008-08-21 01:15:08 +00007926*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007927
7928Core and Builtins
7929-----------------
7930
Guido van Rossumf8402962008-08-20 15:01:50 +00007931- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7932 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7933 extensions do not automatically benefit from the class attribute
7934 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7935 to their tp_flags field if they care. This is a backwards
7936 compatibility feature; in 3.0, all types will use the cache by
7937 default.
7938
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007939- Keyword arguments can now follow starred arguments. (``f(a, *args,
7940 keyword=23)`` is now valid syntax.)
7941
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007942- ctypes function pointers that are COM methods have a boolean True
7943 value again.
7944
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007945- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7946 by denying s# to parse objects that have a releasebuffer procedure,
7947 and introducing s*.
7948
Georg Brandl1e13ea92008-08-11 09:07:59 +00007949- Issue #3537: Fix an assertion failure when an empty but presized dict
7950 object was stored in the freelist.
7951
Mark Dickinsonb6467572008-08-04 21:30:09 +00007952- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7953 ValueError consistently across platforms.
7954
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007955- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7956 (64bit Unix, for example), unichr() would truncate its argument and return
7957 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7958
Neal Norwitze7d8be82008-07-31 17:17:14 +00007959- Apply security patches from Apple.
7960
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007961- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7962 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7963
Antoine Pitrou92f82162008-07-25 22:22:08 +00007964- Issue #1819: function calls with several named parameters are now on
7965 average 35% faster (as measured by pybench).
7966
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007967- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7968 the python debugger steps into a class statement: the free variables (local
7969 variables defined in an outer scope) would be deleted from the outer scope.
7970
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007971- Issue #2620: Overflow checking when allocating or reallocating memory
7972 was not always being done properly in some python types and extension
7973 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7974 all been updated to perform better checks and places in the code that
7975 would previously leak memory on the error path when such an allocation
7976 failed have been fixed.

7979-------
7980
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007981- Issue #3612: Added some missing basic types in ctypes.wintypes.
7982
Benjamin Petersone977ad42008-08-20 01:42:01 +00007983- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7984 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7985
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007986- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7987 version reported by these tools does not necessarily follow the python
7988 version numbering scheme, so the module is less strict when parsing it.
7989
Nick Coghlanf70385a2008-08-18 12:42:46 +00007990- Issue #2235: Added Py3k warnings for types which will become unhashable
7991 under the stricter __hash__ inheritance rules in 3.0. Several types
7992 which did not meet the rules for hash invariants and were already
7993 unhashable in 3.0 have now been explicitly flagged as unhashable in
7994 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7995 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7996
Brett Cannon88f801d2008-08-18 00:46:22 +00007997- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7998 imported into the module but exposed as part of the module's API.
7999
Brett Cannon7b96f072008-08-18 00:41:11 +00008000- Remove an unneeded import of abc.ABCMeta from 'inspect'.
8001
Brett Cannon46225e72008-08-18 00:36:52 +00008002- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00008004- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
8005
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008006- Issue #3575: Incremental decoder's decode function now takes bytearray
8007 by using 's*' instead of 't#'.
8008
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008009- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008010 fails unicode conversion on 2nd parameter. (windows only)
8011
Georg Brandl222e2082010-08-01 22:27:39 +00008012- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008013 in a redirect.
8014
Brett Cannonabe423e2008-08-16 21:47:07 +00008015- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00008016 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008017
Facundo Batistaeb90b782008-08-16 14:44:07 +00008018- Issue #2776: fixed small issue when handling an URL with double slash
8019 after a 302 response in the case of not going through a proxy.
8020
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008021- Issue #2676: in the email package, content-type parsing was hanging on
8022 pathological input because of quadratic or exponential behaviour of a
8023 regular expression.
8024
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008025- Issue #3476: binary buffered reading through the new "io" library is now
8026 thread-safe.
8027
Brett Cannonbf3157b2008-08-14 05:00:03 +00008028- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8029 since mimetools itself is deprecated. Because modules are cached, all
8030 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8031
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008032- Issue #3134: shutil referenced undefined WindowsError symbol.
8033
Robert Schuppenies14646332008-08-10 11:01:53 +00008034- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8035 menu entries were not deleted.
8036
Brett Cannon83e81842008-08-09 23:30:55 +00008037- Copied the implementation of reduce() to _functools.reduce() to have a
8038 version that did not raise a DeprecationWarning under -3.
8039
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008040- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8041 a MemoryError rather than silently stop the iteration.
8042
Guido van Rossum59ce9012008-08-09 14:55:34 +00008043- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8044 to _sre.compile() will now be rejected. This should not affect anybody
8045 since the re.compile() function never generates invalid re-bytecode.
8046
Skip Montanaroa032bf42008-08-08 22:52:51 +00008047- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8048 upon first access it can be automatically initialized from the csv file if
8049 it wasn't initialized during instantiation.
8050
Brett Cannon3aa2a492008-08-06 22:28:09 +00008051- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8052 the reload() built-in has been removed.
8053
Brett Cannon7e30b672008-08-04 21:52:25 +00008054- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008055 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

8058 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
8059 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
8060 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00008061

Antoine Pitroude781a42008-08-09 12:43:23 +00008066 asking for a specific length. This problem only affected files opened

8123-----------------
8124
Georg Brandl3e483f62008-07-16 22:57:41 +00008125- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8126 its methods now allow for items objects that can be converted to
8127 an integer using operator.index().
8128
Mark Dickinson64b7e502008-07-16 09:40:03 +00008129- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8130 produced a ValueError instead of giving the correct float.
8131
Eric Smitha5fa5a22008-07-16 00:11:49 +00008132- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8133 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8134
Mark Dickinson7103aa42008-07-15 19:08:33 +00008135- Issue #3008: the float type has a new instance method 'float.hex'
8136 and a new class method 'float.fromhex' to convert floating-point
8137 numbers to and from hexadecimal strings, respectively.
8138
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008139- Issue #2235: __hash__ is once again inherited by default. To allow
8140 collections.Hashable to remain meaningful in the presence of the
8141 default hash implementation (object.__hash__), it is now possible
8142 to explicit block inheritance of hash by setting __hash__=None at
8143 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8144 level.
8145
Nick Coghlanb028f502008-07-13 14:52:36 +00008146- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8147 the parent module cannot be found while performing an absolute import.
8148 This means that an incorrectly defined __package__ attribute will
8149 now only prevent relative imports in that module rather than causing
8150 all imports from that module to fail.
8151
Nick Coghlan14ff9942008-07-08 14:21:42 +00008152- Issue #2517: Allow unicode messages in Exceptions again by correctly

8162 another thread's dictionary.
8163
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008164- Issue #3004: Minor change to slice.indices(): the start and stop
8165 arguments are now treated identically, making the behaviour easier
8166 to describe and understand. For example, slice(None, -10,
8167 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8168 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8169 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00008171- Issue #3219: Calling a function with repeated keyword arguments,
8172 f(a=2, a=23), would not cause a syntax error. This was a regression
8173 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008211- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8212 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008213 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008214 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008230- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

8640- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00008641
8642- The PyString functions have been renamed to PyBytes. A batch of
8643 defines were added so that the linker still sees the original
8644 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008682- Issue #1631171: Re-implement the 'warnings' module in C (the
8683 original Python code has been kept as backup). This will allow for
8684 using the 'warning's machinery in such places as the parser where
8685 use of pure Python code is not possible. Both the ``showarning()``
8686 and ``formatwarning()`` gain an optional 'line' argument which is
8687 not called by default for backwards-compatibility reasons. Setting
8688 ``warnings.showwarning()`` to an implementation that lacks support
8689 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008731- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008732 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00008752- Issue #2550: The approach used by client/server code for obtaining
8753 ports to listen on in network-oriented tests has been refined in an
8754 effort to facilitate running multiple instances of the entire
8755 regression test suite in parallel without issue.
8756 test_support.bind_port() has been fixed such that it will always
8757 return a unique port -- which wasn't always the case with the
8758 previous implementation, especially if socket options had been set
8759 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8760 new implementation of bind_port() will actually raise an exception
8761 if it is passed an AF_INET/SOCK_STREAM socket with either the
8762 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8763 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8764 the socket it's been passed. This currently only applies to
8765 Windows. This option prevents any other sockets from binding to the
8766 host/port we've bound to, thus removing the possibility of the
8767 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8768 when a second SOCK_STREAM socket binds and accepts to a host/port
8769 that's already been bound by another socket. The optional preferred
8770 port parameter to bind_port() has been removed. Under no
8771 circumstances should tests be hard coding ports!
8772
8773 test_support.find_unused_port() has also been introduced, which will
8774 pass a temporary socket object to bind_port() in order to obtain an
8775 unused port. The temporary socket object is then closed and
8776 deleted, and the port is returned. This method should only be used
8777 for obtaining an unused port in order to pass to an external program
8778 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8779 a parameter to a server-oriented class that doesn't give you direct
8780 access to the underlying socket used.
8781
8782 Finally, test_support.HOST has been introduced, which should be used
8783 for the host argument of any relevant socket calls (i.e. bind and
8784 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008785
8786 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008787 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008788 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8789 test_asynchat and test_socket_ssl.
8790
Georg Brandl3ee81df2008-05-17 18:14:43 +00008791 It is now possible for multiple instances of the regression test
8792 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009071- Added the future_builtins module, which contains hex() and oct().
9072 These are the PEP 3127 version of these functions, designed to be
9073 compatible with the hex() and oct() builtins from Python 3.0. They
9074 differ slightly in their output formats from the existing, unchanged
9075 Python 2.6 builtins. The expected usage of the future_builtins
9076 module is:
9077 from future_builtins import hex, oct
9078
Eric Smith7ef40bf2008-02-20 23:34:22 +00009079- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9080 exponents for exponents with absolute value < 100. Follows C99
9081 standard. This is a change on Windows, which would use 3 digits.
9082 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9083 so that any alterations it does to the resulting string will be
9084 available in stringlib/formatter.h (for float.__format__).
9085
Eric Smith5a3c1352008-02-19 13:21:56 +00009086- Implemented PEP 3101, Advanced String Formatting. This adds a new
9087 builtin format(); a format() method for str and unicode; a
9088 __format__() method to object, str, unicode, int, long, float, and
9089 datetime; the class string.Formatter; and the C API
9090 PyObject_Format().
9091
Georg Brandl3ee81df2008-05-17 18:14:43 +00009092- Fixed several potential crashes, all caused by specially crafted
9093 __del__ methods exploiting objects in temporarily inconsistent
9094 state.

9105 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009106
Georg Brandl3ee81df2008-05-17 18:14:43 +00009107- Issue #2045: Fix an infinite recursion triggered when printing a
9108 subclass of collections.defaultdict, if its default_factory is set
9109 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009137- Patch #1473257: generator objects gain a gi_code attribute. This is
9138 the same object as the func_code attribute of the function that
9139 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009140
Georg Brandl3ee81df2008-05-17 18:14:43 +00009141- Issue #1920: "while 0" statements were completely removed by the
9142 compiler, even in the presence of an "else" clause, which is
9143 supposed to be run when the condition is false. Now the compiler
9144 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009145

9152 dynload_win.c. The error is still reported properly.
9153
Georg Brandl3ee81df2008-05-17 18:14:43 +00009154- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009155 several extension methods and modules do not work without unicode
9156 support.
9157
Georg Brandl26543b12008-01-21 18:36:51 +00009158- Issue #1882: when compiling code from a string, encoding cookies in the
9159 second line of code were not always recognized correctly.
9160
Georg Brandl14404b62008-01-19 19:27:05 +00009161- Issue #1679: "0x" was taken as a valid integer literal.
9162
Georg Brandl6caad7d2008-01-26 14:19:22 +00009163- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009164 added.
9165
Christian Heimesc94e2b52008-01-14 04:13:37 +00009166- sys.float_info / PyFloat_GetInfo: The floating point information
9167 object was converted from a dict to a specialized structseq object.
9168
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169- Patch #1816: Added sys.flags structseq. It exposes the status of
9170 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009171
Georg Brandl3ee81df2008-05-17 18:14:43 +00009172- Objects/structseq.c: Implemented new structseq representation. The
9173 patch makes structseqs (e.g. the return value of os.stat) more
9174 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009175
Georg Brandl3ee81df2008-05-17 18:14:43 +00009176- Patch #1700288: added a type attribute cache that caches method
9177 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009178
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009179- Bug #1776: __import__() no longer accepts filenames on any platform.
9180 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009181
Georg Brandlaed6c662008-01-07 17:25:53 +00009182- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9183
Georg Brandl3ee81df2008-05-17 18:14:43 +00009184- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9185 envvar and sys.dont_write_bytecode attribute. All these can be set
9186 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009187
Georg Brandl3ee81df2008-05-17 18:14:43 +00009188- Improve some exception messages when Windows fails to load an
9189 extension module. Now we get for example '%1 is not a valid Win32
9190 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009191
Georg Brandl3ee81df2008-05-17 18:14:43 +00009192- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009194- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9195 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009196
Christian Heimes0a8143f2007-12-18 23:22:54 +00009197- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009198 and INF. float("nan"), float("inf") and float("-inf") now work on
9199 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009200
Georg Brandl3ee81df2008-05-17 18:14:43 +00009201- Compiler now generates simpler and faster code for dictionary
9202 literals. The oparg for BUILD_MAP now indicates an estimated
9203 dictionary size. There is a new opcode, STORE_MAP, for adding
9204 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009208- Issue #1620: New property decorator syntax was modifying the
9209 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00009210
Georg Brandl3ee81df2008-05-17 18:14:43 +00009211- Issue #1538: Avoid copying string in split/rsplit if the split char
9212 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009213
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009214- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009215 SystemError.
9216
Nick Coghlanef01d822007-12-03 12:55:17 +00009217- PEP 366: Allow explicit relative imports when executing modules
9218 inside packages with the -m switch via a new module level
9219 __package__ attribute.
9220
Georg Brandl3ee81df2008-05-17 18:14:43 +00009221- Issue #1402: Fix a crash on exit, when another thread is still
9222 running, and if the deallocation of its frames somehow calls the
9223 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009224

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00009228 attribute of an empty cell object.
9229
Georg Brandl3ee81df2008-05-17 18:14:43 +00009230- Issue #1460: The utf-7 incremental decoder did not accept truncated
9231 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00009232
Georg Brandl3ee81df2008-05-17 18:14:43 +00009233- Patch #1739468: Directories and zipfiles containing a __main__.py
9234 file can now be directly executed by passing their name to the
9235 interpreter. The directory/zipfile is automatically inserted as the
9236 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009237
Georg Brandl3ee81df2008-05-17 18:14:43 +00009238- Issue #1265: Fix a problem with sys.settrace, if the tracing
9239 function uses a generator expression when at the same time the
9240 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009241
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009242- sets and frozensets now have an isdisjoint() method.
9243
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009244- optimize the performance of builtin.sum().
9245
Neal Norwitz44f326e2007-10-05 05:29:17 +00009246- Fix warnings found by the new version of the Coverity checker.
9247
Georg Brandl21e99f42010-03-07 15:23:59 +00009248- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009249 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9250 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009251
Georg Brandl3ee81df2008-05-17 18:14:43 +00009252- Issue #1686386: Tuple's tp_repr did not take into account the
9253 possibility of having a self-referential tuple, which is possible
9254 from C code. Nor did object's tp_str consider that a type's tp_str
9255 could do something that could lead to an inifinite recursion.
9256 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9257 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009258
Georg Brandl3ee81df2008-05-17 18:14:43 +00009259- Issue #1164: It was possible to trigger deadlock when using the
9260 'print' statement to write to a file since the GIL was not released
9261 as needed. Now PyObject_Print() does the right thing along with
9262 various tp_print implementations of the built-in types and those in
9263 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009264
Georg Brandl3ee81df2008-05-17 18:14:43 +00009265- Issue #1147: Exceptions were directly allowing string exceptions in
9266 their throw() method even though string exceptions no longer
9267 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009268
Georg Brandl3ee81df2008-05-17 18:14:43 +00009269- Issue #1096: Prevent a segfault from getting the repr of a very
9270 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009271
Brett Cannon1e534b52007-09-07 04:18:30 +00009272- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009273 PyObject_Call() never calling back out to Python code to trigger
9274 recursion depth updates/checks. Required the creation of a static
9275 RuntimeError instance in case normalizing an exception put the
9276 recursion check value past its limit. Fixes crashers
9277 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009278
Georg Brandl3ee81df2008-05-17 18:14:43 +00009279- Patch #1031213: Decode source line in SyntaxErrors back to its

9283 with %G.
9284
Georg Brandl3ee81df2008-05-17 18:14:43 +00009285- Prevent expandtabs() on string and unicode objects from causing a
9286 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00009287

Georg Brandla5ea6892007-06-01 11:33:33 +00009291
Neal Norwitz0ac60192007-05-27 04:08:54 +00009292- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009293 __*__ attributes. (Some already existed, e.g., __doc__ and
9294 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009295
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009296- Add -3 option to the interpreter to warn about features that are
9297 deprecated and will be changed/removed in Python 3.0.
9298
Georg Brandl2134e752007-05-21 20:34:16 +00009299- Patch #1686487: you can now pass any mapping after '**' in function
9300 calls.
9301
Collin Winter62903052007-05-18 23:11:24 +00009302- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009303 "except E as target:". This is to provide forwards compatibility
9304 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009305
Brett Cannon229cee22007-05-05 01:34:02 +00009306- Deprecate BaseException.message as per PEP 352.
9307
Georg Brandl3ee81df2008-05-17 18:14:43 +00009308- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009309 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009310
Vinay Sajip8549ce32007-05-06 17:53:37 +00009311- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009312 setting a plain string, ie don't expand to single letter identifiers.
9313
Raymond Hettinger13936692007-04-11 18:40:58 +00009314- Request #1191699: Slices can now be pickled.
9315
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009316- Request #1193128: str.translate() now allows a None argument for
9317 translations that only remove characters without re-mapping the
9318 remaining characters.
9319
Georg Brandl5cb76c12007-03-21 09:00:39 +00009320- Patch #1682205: a TypeError while unpacking an iterable is no longer
9321 masked by a generic one with the message "unpack non-sequence".
9322
Neal Norwitzaa754b72007-03-21 06:39:48 +00009323- Remove unused file Python/fmod.c.
9324
Guido van Rossum143b5642007-03-23 04:58:42 +00009325- Bug #1683368: The object.__init__() and object.__new__() methods are
9326 now stricter in rejecting excess arguments. The only time when
9327 either allows excess arguments is when it is not overridden and the
9328 other one is. For backwards compatibility, when both are
9329 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009330 warning later). Also, type.__init__() insists on the same signature
9331 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009332
Georg Brandl3ee81df2008-05-17 18:14:43 +00009333- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9334 object to complex using its __complex__() method before falling back
9335 to the __float__() method. Therefore, the functions in the cmath
9336 module now can operate on objects that define a __complex__()
9337 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009338
Georg Brandl3ee81df2008-05-17 18:14:43 +00009339- Patch #1623563: allow __class__ assignment for classes with
9340 __slots__. The old and the new class are still required to have the
9341 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009342
Georg Brandl3ee81df2008-05-17 18:14:43 +00009343- Patch #1642547: Fix an error/crash when encountering syntax errors
9344 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009346- Patch #1462488: Python no longer segfaults when
9347 ``object.__reduce_ex__()`` is called with an object that is faking
9348 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009349
Georg Brandl3ee81df2008-05-17 18:14:43 +00009350- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00009353- Patch #1444529: the builtin compile() now accepts keyword arguments.
9354
Georg Brandl7b9c5552007-03-12 14:30:05 +00009355- Bug #1678647: write a newline after printing an exception in any
9356 case, even when converting the value to a string failed.
9357
Georg Brandl871f1bc2007-03-12 13:17:36 +00009358- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009359 its argument, if it exists. If not, it will work like before. This
9360 allows customizing the output of dir() in the presence of a
9361 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009362
Collin Winter276887b2007-03-12 16:11:39 +00009363- Patch #922167: Python no longer segfaults when faced with infinitely
9364 self-recursive reload() calls (as reported by bug #742342).
9365
Georg Brandl3ee81df2008-05-17 18:14:43 +00009366- Patch #1675981: remove unreachable code from ``type.__new__()``
9367 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009369- Patch #1491866: change the complex() constructor to allow
9370 parthensized forms. This means complex(repr(x)) now works instead of
9371 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009372
Georg Brandlaa2321b2007-03-07 00:40:28 +00009373- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009374 makes the filenames the warning module prints much more sensible
9375 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009376
Georg Brandl49aafc92007-03-07 00:34:46 +00009377- Variant of patch #697613: don't exit the interpreter on a SystemExit
9378 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00009379 variable is given, but break into the interactive interpreter just
9380 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009385- Bug #1674503: close the file opened by execfile() in an error
9386 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00009387

9881 ".cpp" too.
9882
Facundo Batistad918a652007-04-24 13:54:38 +00009883- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009884 the client's request was successfully received, understood, and
9885 accepted. Now in these cases no error is raised in urllib (issue
9886 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00009887

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009894- Added a timeout parameter to the constructor of other protocols
9895 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9896 work started with create_connection() and timeout in httplib, and
9897 closes patch #723312.
9898
Vinay Sajip8549ce32007-05-06 17:53:37 +00009899- Patch #1676823: Added create_connection() to socket.py, which may be
9900 called with a timeout, and use it from httplib (whose HTTPConnection

Georg Brandl3ee81df2008-05-17 18:14:43 +00009925 AttributeError instead of an IOError when the server's response
9926 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009927

9933 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009934 correctly now.
9935

9942
Georg Brandl3ee81df2008-05-17 18:14:43 +00009943- Patch #1530482: add pydoc.render_doc() which returns the

9958
Georg Brandl92a6bae2007-03-13 17:43:32 +00009959- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009960 are set for invalid interpolation sequences that would lead to
9961 errors on reading back those values.

10015
Georg Brandl3ee81df2008-05-17 18:14:43 +000010016- unittest now verifies more of its assumptions. In particular,
10017 TestCase and TestSuite subclasses (not instances) are no longer
10018 accepted in TestSuite.addTest(). This should cause no

10020 -- the failure just occurred later, with a more cumbersome
10021 exception.

10386 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10387 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010403- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000010404 time so that opening a database previously created with the DB_DUP
10405 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10406 opens. Specifically: dictionary assignment to a DB object will
10407 replace all values for a given key when the database allows
10408 duplicate values. DB users should use DB.put(k, v) when they want
10409 to store duplicates; not DB[k] = v.

10416 characters with ASCII value less than 32. Also, it correctly quotes
10417 dots only if they occur on a single line, as opposed to the previous
10418 behavior of quoting dots if they are the second character of any
10419 line.
