483
484- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
485 and later systems as is currently done for Python 3.x installers.
486 For 2.7.7 only, we will provide three installers:
487 the legacy deprecated 10.3+ 32-bit-only format;
488 the newer 10.5+ 32-bit-only format;
489 and the unchanged 10.6+ 64-/32-bit format.
490 Although binary installers will no longer be available from
491 python.org as of 2.7.8, it will still be possible to build from
492 source on 10.3.9 and 10.4 systems if necessary.

1872 32-bit-only installer Pythons on systems with Xcode 4 (currently
1873 OS X 10.8, 10.7, and optionally 10.6).
1874 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1875 * Since Xcode 4 removes ppc support, extension module builds now
1876 check for ppc compiler support and by default remove ppc and
1877 ppc64 archs when they are not available.
1878 * Extension module builds now revert to using system installed
1879 headers and libs (/usr and /System/Library) if the SDK used
1880 to build the interpreter is not installed or has moved.
1881 * Try to avoid building extension modules with deprecated
1882 and problematic Apple llvm-gcc compiler. If original compiler
1883 is not available, use clang instead by default.

2317 64-bit/32-bit Pythons. If the user does not explicitly override
2318 the default C compiler by setting the CC environment variable,
2319 Distutils will now attempt to compile extension modules with clang
2320 if gcc-4.2 is required but not found. Also as a convenience, if
2321 the user does explicitly set CC, substitute its value as the default
2322 compiler in the Distutils LDSHARED configuration variable for OS X.
2323 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2324 SDK, neither of which are available in Xcode 4. This change does not
2325 attempt to override settings to support their use with Xcode 4.)

2576 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2577 interpreter process. This could cause failures in non-Distutils subprocesses
2578 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002579 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002580 deployment target only in the environment of each build subprocess. It is
2581 still possible to globally override the default by setting

Barry Warsawc5643282011-07-19 17:06:30 -04002612- sys.setcheckinterval() now updates the current ticker count as well as
2613 updating the check interval, so if the user decreases the check interval,
2614 the ticker doesn't have to wind down to zero from the old starting point
2615 before the new interval takes effect. And if the user increases the
2616 interval, it makes sure the new limit takes effect right away rather have an
2617 early task switch before recognizing the new interval.

3587 by Andrew Bennetts.

3596
Raymond Hettinger20397532010-09-12 02:11:45 +00003597- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3598 This prevents user-created self-referencing ordered dictionaries from
3599 becoming permanently uncollectable GC garbage. The downside is that
3600 removing __del__ means that the internal doubly-linked list has to wait for
3601 GC collection rather than freeing memory immediately when the refcnt drops
3602 to zero.
3603
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003604- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3607
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003608- Issue #9792: In case of connection failure, socket.create_connection()
3609 would swallow the exception and raise a new one, making it impossible
3610 to fetch the original errno, or to filter timeout errors. Now the
3611 original error is re-raised.
3612
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003613- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3614 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3615 be updated back after the system call. Original patch by Brian Brazil.

3622
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003623- Issue #808164: Fixed socket.close to avoid references to globals, to

3627 can be set to False to turn off the previously undocumented 'popularity'
3628 heuristic. Patch by Terry Reedy and Eli Bendersky
3629

3631 falling into recursion.
3632
R. David Murray7c4bf552010-08-25 01:45:57 +00003633- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3634 character years even if the message contains RFC822 two character years.
3635
Daniel Stutzbach91287322010-08-24 21:09:30 +00003636- Issue #8750: Fixed MutableSet's methods to correctly handle

3648 module now correctly return a set. (Patch by Eli Bendersky.)
3649
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003650- Issue #9617: Signals received during a low-level write operation aren't
3651 ignored by the buffered IO layer anymore.
3652
Benjamin Peterson52c36052010-08-21 03:03:22 +00003653- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3654 are not held onto after they are deleted elsewhere.
3655
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003656- Issue #9626: the view methods for collections.OrderedDict() were returning
3657 the unordered versions inherited from dict. Those methods are now
3658 overridden to provide ordered views.
3659
Éric Araujo0389ae62010-08-14 03:07:46 +00003660- Issue #8688: MANIFEST files created by distutils now include a magic
3661 comment indicating they are generated. Manually maintained MANIFESTs
3662 without this marker will not be overwritten or removed.
3663
Antoine Pitroue1436d12010-08-12 15:25:51 +00003664- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3665 and a BadZipfile error is raised if it doesn't match (as used to be the
3666 case in Python 2.5 and earlier).
3667
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003668- Issue #9550: a BufferedReader could issue an additional read when the
3669 original read request had been satisfied, which could block indefinitely
3670 when the underlying raw IO channel was e.g. a socket. Report and original
3671 patch by Jason V. Miller.
3672
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003673- Issue #9551: Don't raise TypeError when setting the value to None for

3692 This is how it is supposed to work, wget and curl do the same. Previous
3693 behavior was wrong.

3699
R. David Murray1cbf78e2010-08-03 18:14:01 +00003700- Issue #9444: Argparse now uses the first element of prefix_chars as
3701 the option character for the added 'h/help' option if prefix_chars
3702 does not contain a '-', instead of raising an error.
3703

4065 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4066 Previous versions returned a single u'\ufffd'.

4075 objects. (1) The comparison could incorrectly return True in some cases
4076 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4077 (2) The comparison raised an OverflowError for large integers, leading
4078 to unpredictable exceptions when combining integers and complex objects

Georg Brandlfee0f442010-05-22 21:26:21 +00004320- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4321 the method could block indefinitely if called just before the event loop

Antoine Pitroufc69af12010-04-24 20:04:58 +00004325- Issue #5103: SSL handshake would ignore the socket timeout and block
4326 indefinitely if the other end didn't respond.
4327
Georg Brandlfee0f442010-05-22 21:26:21 +00004328- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004421 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

4447
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004448- Issue #8329: Don't return the same lists from select.select when no fds are
4449 changed.
4450
Georg Brandlfee0f442010-05-22 21:26:21 +00004451- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004452 on 64-bit machines. The shift count for either left or right shift is
4453 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00004461- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4462 with a non-empty format string. This is an effort to future-proof user
4463 code. If a derived class does not currently implement __format__ but later
4464 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004465 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004466 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004516- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4517 InvalidOperation instead of returning False. (Comparisons involving a quiet
4518 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4519 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004520
Georg Brandlfee0f442010-05-22 21:26:21 +00004521- Issue #2531: Comparison operations between floats and Decimal instances now
4522 return a result based on the numeric values of the operands; previously they
4523 returned an arbitrary result based on the relative ordering of id(float) and
4524 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00004538- Comparisons using one of <, <=, >, >= between a complex instance and a
4539 Fractions instance now raise TypeError instead of returning True/False. This
4540 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4541 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004959 file position when calling `truncate()`. It would previously change the file
4960 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004961 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4964 class used to represent files stored inside an archive. The new
4965 implementation is significantly faster and can be wrapped in a

4967 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5056-----------------
5057
Georg Brandlba83f822010-03-14 09:50:54 +00005058- The ``__complex__()`` method is now looked up on the class of instances to
5059 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005060
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005061- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5062 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5063
Mark Dickinson1b34d252010-01-01 17:27:30 +00005064- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005065 DeprecationWarning when passed a float argument where an integer was expected.
5066 These functions and methods now raise TypeError instead. The majority of the
5067 effects of this change are in the extension modules, but some core functions
5068 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5069 and many unicode/str methods.

5080 used to drop the time part of the result.
5081
Georg Brandlba83f822010-03-14 09:50:54 +00005082- Issue #1811: Improve accuracy and cross-platform consistency for true division
5083 of integers: the result of a/b is now correctly rounded for ints a and b (at
5084 least on IEEE 754 platforms), and in particular does not depend on the
5085 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00005086
Georg Brandlba83f822010-03-14 09:50:54 +00005087- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00005092 executables on OSX.
5093
Georg Brandlba83f822010-03-14 09:50:54 +00005094 These executables now work properly with the arch(1) command: ``arch -ppc
5095 python`` will start a universal binary version of python in PPC mode (unlike
5096 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00005097
Georg Brandlba83f822010-03-14 09:50:54 +00005098- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +00005118 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
5119 alternative to cPickle if you care about performance. Patch by Florent

Georg Brandlba83f822010-03-14 09:50:54 +00005258- Issue #7117: On almost all platforms: float-to-string and string-to-float
5259 conversions within Python are now correctly rounded. Places these conversions
5260 occur include: str for floats and complex numbers; the float and complex
5261 constructors; old-style and new-style numeric formatting; serialization and
5262 deserialization of floats and complex numbers using marshal, pickle and json;
5263 parsing of float and imaginary literals in Python code; Decimal-to-float
5264 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005265
Georg Brandlba83f822010-03-14 09:50:54 +00005266 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5267 providing correctly-rounded strtod and dtoa C functions. This code is
5268 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5269 the C compiler. There may be a small number of platforms on which correct
5270 operation of this code cannot be guaranteed, so the code is not used: notably,
5271 this applies to platforms where the C double format is not IEEE 754 binary64,
5272 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5273 and Python's configure script is unable to determine how to change the FPU
5274 precision. On these platforms conversions use the platform strtod and dtoa,
5275 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005277- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5278 uses the correctly-rounded string <-> float conversions described above (when
5279 available), and so produces correctly rounded results that will display nicely
5280 under the float repr. There are two related small changes: (1) round now
5281 accepts any class with an ``__index__()`` method for its second argument (but
5282 no longer accepts floats for the second argument), and (2) an excessively
5283 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5284 raises an exception.

6869 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6870 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6871 neither __int__ nor __long__, TypeError used to be raised (with a
6872 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6873 struct.error in other cases.

6876 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007070- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7072 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7073 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00007171 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7172 for catch_warnings() also led to an improvement in the raising of a
7173 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007239What's New in Python 2.6 beta 3?
7240================================
7241
Barry Warsaw07a4a382008-08-21 01:15:08 +00007242*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007243
7244Core and Builtins
7245-----------------
7246
Guido van Rossumf8402962008-08-20 15:01:50 +00007247- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7248 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7249 extensions do not automatically benefit from the class attribute
7250 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7251 to their tp_flags field if they care. This is a backwards
7252 compatibility feature; in 3.0, all types will use the cache by
7253 default.
7254
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007255- Keyword arguments can now follow starred arguments. (``f(a, *args,
7256 keyword=23)`` is now valid syntax.)
7257
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007258- ctypes function pointers that are COM methods have a boolean True
7259 value again.
7260
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007261- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7262 by denying s# to parse objects that have a releasebuffer procedure,
7263 and introducing s*.
7264
Georg Brandl1e13ea92008-08-11 09:07:59 +00007265- Issue #3537: Fix an assertion failure when an empty but presized dict
7266 object was stored in the freelist.
7267
Mark Dickinsonb6467572008-08-04 21:30:09 +00007268- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7269 ValueError consistently across platforms.
7270
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007271- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7272 (64bit Unix, for example), unichr() would truncate its argument and return
7273 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7274
Neal Norwitze7d8be82008-07-31 17:17:14 +00007275- Apply security patches from Apple.
7276
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007277- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7278 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7279
Antoine Pitrou92f82162008-07-25 22:22:08 +00007280- Issue #1819: function calls with several named parameters are now on
7281 average 35% faster (as measured by pybench).
7282
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007283- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7284 the python debugger steps into a class statement: the free variables (local
7285 variables defined in an outer scope) would be deleted from the outer scope.
7286
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007287- Issue #2620: Overflow checking when allocating or reallocating memory
7288 was not always being done properly in some python types and extension
7289 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7290 all been updated to perform better checks and places in the code that
7291 would previously leak memory on the error path when such an allocation
7292 failed have been fixed.

7295-------
7296
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007297- Issue #3612: Added some missing basic types in ctypes.wintypes.
7298
Benjamin Petersone977ad42008-08-20 01:42:01 +00007299- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7300 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7301
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007302- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7303 version reported by these tools does not necessarily follow the python
7304 version numbering scheme, so the module is less strict when parsing it.
7305
Nick Coghlanf70385a2008-08-18 12:42:46 +00007306- Issue #2235: Added Py3k warnings for types which will become unhashable
7307 under the stricter __hash__ inheritance rules in 3.0. Several types
7308 which did not meet the rules for hash invariants and were already
7309 unhashable in 3.0 have now been explicitly flagged as unhashable in
7310 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7311 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7312
Brett Cannon88f801d2008-08-18 00:46:22 +00007313- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7314 imported into the module but exposed as part of the module's API.
7315
Brett Cannon7b96f072008-08-18 00:41:11 +00007316- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7317
Brett Cannon46225e72008-08-18 00:36:52 +00007318- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007320- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7321
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007322- Issue #3575: Incremental decoder's decode function now takes bytearray
7323 by using 's*' instead of 't#'.
7324
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007325- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007326 fails unicode conversion on 2nd parameter. (windows only)
7327
Georg Brandl222e2082010-08-01 22:27:39 +00007328- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007329 in a redirect.
7330
Brett Cannonabe423e2008-08-16 21:47:07 +00007331- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007332 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007333
Facundo Batistaeb90b782008-08-16 14:44:07 +00007334- Issue #2776: fixed small issue when handling an URL with double slash
7335 after a 302 response in the case of not going through a proxy.
7336
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007337- Issue #2676: in the email package, content-type parsing was hanging on
7338 pathological input because of quadratic or exponential behaviour of a
7339 regular expression.
7340
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007341- Issue #3476: binary buffered reading through the new "io" library is now
7342 thread-safe.
7343
Brett Cannonbf3157b2008-08-14 05:00:03 +00007344- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7345 since mimetools itself is deprecated. Because modules are cached, all
7346 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7347
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007348- Issue #3134: shutil referenced undefined WindowsError symbol.
7349
Robert Schuppenies14646332008-08-10 11:01:53 +00007350- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7351 menu entries were not deleted.
7352
Brett Cannon83e81842008-08-09 23:30:55 +00007353- Copied the implementation of reduce() to _functools.reduce() to have a
7354 version that did not raise a DeprecationWarning under -3.
7355
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007356- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7357 a MemoryError rather than silently stop the iteration.
7358
Guido van Rossum59ce9012008-08-09 14:55:34 +00007359- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7360 to _sre.compile() will now be rejected. This should not affect anybody
7361 since the re.compile() function never generates invalid re-bytecode.
7362
Skip Montanaroa032bf42008-08-08 22:52:51 +00007363- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7364 upon first access it can be automatically initialized from the csv file if
7365 it wasn't initialized during instantiation.
7366
Brett Cannon3aa2a492008-08-06 22:28:09 +00007367- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7368 the reload() built-in has been removed.
7369
Brett Cannon7e30b672008-08-04 21:52:25 +00007370- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007371 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007382 asking for a specific length. This problem only affected files opened
7383 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007384
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007385- Issue #3449: Update decimal module to use most recent specification
7386 (v. 1.68) and tests (v. 2.58) from IBM.

7439-----------------
7440
Georg Brandl3e483f62008-07-16 22:57:41 +00007441- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7442 its methods now allow for items objects that can be converted to
7443 an integer using operator.index().
7444
Mark Dickinson64b7e502008-07-16 09:40:03 +00007445- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7446 produced a ValueError instead of giving the correct float.
7447
Eric Smitha5fa5a22008-07-16 00:11:49 +00007448- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7449 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7450
Mark Dickinson7103aa42008-07-15 19:08:33 +00007451- Issue #3008: the float type has a new instance method 'float.hex'
7452 and a new class method 'float.fromhex' to convert floating-point
7453 numbers to and from hexadecimal strings, respectively.
7454
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007455- Issue #2235: __hash__ is once again inherited by default. To allow
7456 collections.Hashable to remain meaningful in the presence of the
7457 default hash implementation (object.__hash__), it is now possible
7458 to explicit block inheritance of hash by setting __hash__=None at
7459 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7460 level.
7461
Nick Coghlanb028f502008-07-13 14:52:36 +00007462- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7463 the parent module cannot be found while performing an absolute import.
7464 This means that an incorrectly defined __package__ attribute will
7465 now only prevent relative imports in that module rather than causing
7466 all imports from that module to fail.
7467
Nick Coghlan14ff9942008-07-08 14:21:42 +00007468- Issue #2517: Allow unicode messages in Exceptions again by correctly

7477 threading.local: the first member set by a thread could be saved in
7478 another thread's dictionary.
7479
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007480- Issue #3004: Minor change to slice.indices(): the start and stop
7481 arguments are now treated identically, making the behaviour easier
7482 to describe and understand. For example, slice(None, -10,
7483 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7484 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7485 10, -1).
7486
Georg Brandl278fc502008-07-19 12:46:12 +00007487- Issue #3219: Calling a function with repeated keyword arguments,
7488 f(a=2, a=23), would not cause a syntax error. This was a regression
7489 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007490
Georg Brandl278fc502008-07-19 12:46:12 +00007491- Issue #2862: Make int and float freelist management consistent with
7492 other freelists. Changes their CompactFreeList apis into

7499 api functions without holding the GIL, which could lead to a fatal
7500 error when they failed.
7501
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007502- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007527- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7528 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007529 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007530 content-length. The problem had been corrected in the 2.4 branch, but never
7531 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007546- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- Issue #1631171: Re-implement the 'warnings' module in C (the
7999 original Python code has been kept as backup). This will allow for
8000 using the 'warning's machinery in such places as the parser where
8001 use of pure Python code is not possible. Both the ``showarning()``
8002 and ``formatwarning()`` gain an optional 'line' argument which is
8003 not called by default for backwards-compatibility reasons. Setting
8004 ``warnings.showwarning()`` to an implementation that lacks support
8005 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008068- Issue #2550: The approach used by client/server code for obtaining
8069 ports to listen on in network-oriented tests has been refined in an
8070 effort to facilitate running multiple instances of the entire
8071 regression test suite in parallel without issue.
8072 test_support.bind_port() has been fixed such that it will always
8073 return a unique port -- which wasn't always the case with the
8074 previous implementation, especially if socket options had been set
8075 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8076 new implementation of bind_port() will actually raise an exception
8077 if it is passed an AF_INET/SOCK_STREAM socket with either the
8078 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8079 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8080 the socket it's been passed. This currently only applies to
8081 Windows. This option prevents any other sockets from binding to the
8082 host/port we've bound to, thus removing the possibility of the
8083 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8084 when a second SOCK_STREAM socket binds and accepts to a host/port
8085 that's already been bound by another socket. The optional preferred
8086 port parameter to bind_port() has been removed. Under no
8087 circumstances should tests be hard coding ports!
8088
8089 test_support.find_unused_port() has also been introduced, which will
8090 pass a temporary socket object to bind_port() in order to obtain an
8091 unused port. The temporary socket object is then closed and
8092 deleted, and the port is returned. This method should only be used
8093 for obtaining an unused port in order to pass to an external program
8094 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8095 a parameter to a server-oriented class that doesn't give you direct
8096 access to the underlying socket used.
8097
8098 Finally, test_support.HOST has been introduced, which should be used
8099 for the host argument of any relevant socket calls (i.e. bind and
8100 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008101
8102 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008103 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008104 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8105 test_asynchat and test_socket_ssl.
8106
Georg Brandl3ee81df2008-05-17 18:14:43 +00008107 It is now possible for multiple instances of the regression test
8108 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008387- Added the future_builtins module, which contains hex() and oct().
8388 These are the PEP 3127 version of these functions, designed to be
8389 compatible with the hex() and oct() builtins from Python 3.0. They
8390 differ slightly in their output formats from the existing, unchanged
8391 Python 2.6 builtins. The expected usage of the future_builtins
8392 module is:
8393 from future_builtins import hex, oct
8394
Eric Smith7ef40bf2008-02-20 23:34:22 +00008395- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8396 exponents for exponents with absolute value < 100. Follows C99
8397 standard. This is a change on Windows, which would use 3 digits.
8398 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8399 so that any alterations it does to the resulting string will be
8400 available in stringlib/formatter.h (for float.__format__).
8401
Eric Smith5a3c1352008-02-19 13:21:56 +00008402- Implemented PEP 3101, Advanced String Formatting. This adds a new
8403 builtin format(); a format() method for str and unicode; a
8404 __format__() method to object, str, unicode, int, long, float, and
8405 datetime; the class string.Formatter; and the C API
8406 PyObject_Format().
8407
Georg Brandl3ee81df2008-05-17 18:14:43 +00008408- Fixed several potential crashes, all caused by specially crafted
8409 __del__ methods exploiting objects in temporarily inconsistent
8410 state.

8421 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008422
Georg Brandl3ee81df2008-05-17 18:14:43 +00008423- Issue #2045: Fix an infinite recursion triggered when printing a
8424 subclass of collections.defaultdict, if its default_factory is set
8425 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008426
Christian Heimesf75dbef2008-02-08 00:11:31 +00008427- Fixed a minor memory leak in dictobject.c. The content of the free

8434 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008435 to compact the internal free lists of pre-allocted ints and floats.
8436
Georg Brandl3ee81df2008-05-17 18:14:43 +00008437- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8438 calls. Python expected the return type int but the fork familie
8439 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008453- Patch #1473257: generator objects gain a gi_code attribute. This is
8454 the same object as the func_code attribute of the function that
8455 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008456
Georg Brandl3ee81df2008-05-17 18:14:43 +00008457- Issue #1920: "while 0" statements were completely removed by the
8458 compiler, even in the presence of an "else" clause, which is
8459 supposed to be run when the condition is false. Now the compiler
8460 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008461

8478
Georg Brandl6caad7d2008-01-26 14:19:22 +00008479- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008480 added.
8481
Christian Heimesc94e2b52008-01-14 04:13:37 +00008482- sys.float_info / PyFloat_GetInfo: The floating point information
8483 object was converted from a dict to a specialized structseq object.
8484
Georg Brandl3ee81df2008-05-17 18:14:43 +00008485- Patch #1816: Added sys.flags structseq. It exposes the status of
8486 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008487
Georg Brandl3ee81df2008-05-17 18:14:43 +00008488- Objects/structseq.c: Implemented new structseq representation. The
8489 patch makes structseqs (e.g. the return value of os.stat) more
8490 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008491
Georg Brandl3ee81df2008-05-17 18:14:43 +00008492- Patch #1700288: added a type attribute cache that caches method
8493 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008494
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008495- Bug #1776: __import__() no longer accepts filenames on any platform.
8496 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008497
Georg Brandlaed6c662008-01-07 17:25:53 +00008498- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8499
Georg Brandl3ee81df2008-05-17 18:14:43 +00008500- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8501 envvar and sys.dont_write_bytecode attribute. All these can be set
8502 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008503
Georg Brandl3ee81df2008-05-17 18:14:43 +00008504- Improve some exception messages when Windows fails to load an
8505 extension module. Now we get for example '%1 is not a valid Win32
8506 application' instead of 'error code 193'.

8511 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008512
Christian Heimes0a8143f2007-12-18 23:22:54 +00008513- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008514 and INF. float("nan"), float("inf") and float("-inf") now work on
8515 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008516
Georg Brandl3ee81df2008-05-17 18:14:43 +00008517- Compiler now generates simpler and faster code for dictionary
8518 literals. The oparg for BUILD_MAP now indicates an estimated
8519 dictionary size. There is a new opcode, STORE_MAP, for adding
8520 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008549- Patch #1739468: Directories and zipfiles containing a __main__.py
8550 file can now be directly executed by passing their name to the
8551 interpreter. The directory/zipfile is automatically inserted as the
8552 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008553
Georg Brandl3ee81df2008-05-17 18:14:43 +00008554- Issue #1265: Fix a problem with sys.settrace, if the tracing
8555 function uses a generator expression when at the same time the
8556 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008557
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008558- sets and frozensets now have an isdisjoint() method.
8559
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008560- optimize the performance of builtin.sum().
8561
Neal Norwitz44f326e2007-10-05 05:29:17 +00008562- Fix warnings found by the new version of the Coverity checker.
8563
Georg Brandl21e99f42010-03-07 15:23:59 +00008564- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008565 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8566 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008567
Georg Brandl3ee81df2008-05-17 18:14:43 +00008568- Issue #1686386: Tuple's tp_repr did not take into account the
8569 possibility of having a self-referential tuple, which is possible
8570 from C code. Nor did object's tp_str consider that a type's tp_str
8571 could do something that could lead to an inifinite recursion.
8572 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8573 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008574
Georg Brandl3ee81df2008-05-17 18:14:43 +00008575- Issue #1164: It was possible to trigger deadlock when using the
8576 'print' statement to write to a file since the GIL was not released
8577 as needed. Now PyObject_Print() does the right thing along with
8578 various tp_print implementations of the built-in types and those in
8579 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008580
Georg Brandl3ee81df2008-05-17 18:14:43 +00008581- Issue #1147: Exceptions were directly allowing string exceptions in
8582 their throw() method even though string exceptions no longer
8583 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008584
Georg Brandl3ee81df2008-05-17 18:14:43 +00008585- Issue #1096: Prevent a segfault from getting the repr of a very
8586 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008587
Brett Cannon1e534b52007-09-07 04:18:30 +00008588- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008589 PyObject_Call() never calling back out to Python code to trigger
8590 recursion depth updates/checks. Required the creation of a static
8591 RuntimeError instance in case normalizing an exception put the
8592 recursion check value past its limit. Fixes crashers
8593 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008594

Neal Norwitz0ac60192007-05-27 04:08:54 +00008608- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008609 __*__ attributes. (Some already existed, e.g., __doc__ and
8610 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008611
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008612- Add -3 option to the interpreter to warn about features that are
8613 deprecated and will be changed/removed in Python 3.0.
8614
Georg Brandl2134e752007-05-21 20:34:16 +00008615- Patch #1686487: you can now pass any mapping after '**' in function
8616 calls.
8617
Collin Winter62903052007-05-18 23:11:24 +00008618- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008619 "except E as target:". This is to provide forwards compatibility
8620 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008621
Brett Cannon229cee22007-05-05 01:34:02 +00008622- Deprecate BaseException.message as per PEP 352.
8623
Georg Brandl3ee81df2008-05-17 18:14:43 +00008624- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008625 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008626
Vinay Sajip8549ce32007-05-06 17:53:37 +00008627- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008628 setting a plain string, ie don't expand to single letter identifiers.
8629
Raymond Hettinger13936692007-04-11 18:40:58 +00008630- Request #1191699: Slices can now be pickled.
8631
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008632- Request #1193128: str.translate() now allows a None argument for
8633 translations that only remove characters without re-mapping the
8634 remaining characters.
8635
Georg Brandl5cb76c12007-03-21 09:00:39 +00008636- Patch #1682205: a TypeError while unpacking an iterable is no longer
8637 masked by a generic one with the message "unpack non-sequence".
8638
Neal Norwitzaa754b72007-03-21 06:39:48 +00008639- Remove unused file Python/fmod.c.
8640
Guido van Rossum143b5642007-03-23 04:58:42 +00008641- Bug #1683368: The object.__init__() and object.__new__() methods are
8642 now stricter in rejecting excess arguments. The only time when
8643 either allows excess arguments is when it is not overridden and the
8644 other one is. For backwards compatibility, when both are
8645 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008646 warning later). Also, type.__init__() insists on the same signature
8647 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008648
Georg Brandl3ee81df2008-05-17 18:14:43 +00008649- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8650 object to complex using its __complex__() method before falling back
8651 to the __float__() method. Therefore, the functions in the cmath
8652 module now can operate on objects that define a __complex__()
8653 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008654
Georg Brandl3ee81df2008-05-17 18:14:43 +00008655- Patch #1623563: allow __class__ assignment for classes with
8656 __slots__. The old and the new class are still required to have the
8657 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008658
Georg Brandl3ee81df2008-05-17 18:14:43 +00008659- Patch #1642547: Fix an error/crash when encountering syntax errors

8663 ``object.__reduce_ex__()`` is called with an object that is faking
8664 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008665
Georg Brandl3ee81df2008-05-17 18:14:43 +00008666- Patch #1680015: Don't modify __slots__ tuple if it contains an

8670
Georg Brandl7b9c5552007-03-12 14:30:05 +00008671- Bug #1678647: write a newline after printing an exception in any
8672 case, even when converting the value to a string failed.
8673
Georg Brandl871f1bc2007-03-12 13:17:36 +00008674- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008675 its argument, if it exists. If not, it will work like before. This
8676 allows customizing the output of dir() in the presence of a
8677 __getattr__().

8681
Georg Brandl3ee81df2008-05-17 18:14:43 +00008682- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00008685- Patch #1491866: change the complex() constructor to allow
8686 parthensized forms. This means complex(repr(x)) now works instead of
8687 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008688
Georg Brandlaa2321b2007-03-07 00:40:28 +00008689- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008690 makes the filenames the warning module prints much more sensible
8691 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008692
Georg Brandl49aafc92007-03-07 00:34:46 +00008693- Variant of patch #697613: don't exit the interpreter on a SystemExit
8694 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008695 variable is given, but break into the interactive interpreter just
8696 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008704- Patch #1674228: when assigning a slice (old-style), check for the
8705 sq_ass_slice instead of the sq_slice slot.
8706
Georg Brandl3ee81df2008-05-17 18:14:43 +00008707- When printing an unraisable error, don't print exceptions. before
8708 the name. This duplicates the behavior whening normally printing
8709 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009210- Added a timeout parameter to the constructor of other protocols
9211 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9212 work started with create_connection() and timeout in httplib, and
9213 closes patch #723312.
9214
Vinay Sajip8549ce32007-05-06 17:53:37 +00009215- Patch #1676823: Added create_connection() to socket.py, which may be
9216 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00009217 and HTTPSConnection now accept an optional timeout).

9239
Georg Brandlf66b6032007-03-14 08:27:52 +00009240- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00009241 AttributeError instead of an IOError when the server's response
9242 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009243
Georg Brandl3ee81df2008-05-17 18:14:43 +00009244- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00009248- Patch #1429539: pdb now correctly initializes the __main__ module
9249 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009250 correctly now.
9251

9258
Georg Brandl3ee81df2008-05-17 18:14:43 +00009259- Patch #1530482: add pydoc.render_doc() which returns the

9269 parameter which can be set to False to prevent the default
9270 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00009272- Patch #1581073: add a flag to textwrap that prevents the dropping of
9273 whitespace while wrapping.
9274
Georg Brandl92a6bae2007-03-13 17:43:32 +00009275- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009276 are set for invalid interpolation sequences that would lead to
9277 errors on reading back those values.

9320 returned string up to the first NUL character.
9321

9331
Georg Brandl3ee81df2008-05-17 18:14:43 +00009332- unittest now verifies more of its assumptions. In particular,
9333 TestCase and TestSuite subclasses (not instances) are no longer
9334 accepted in TestSuite.addTest(). This should cause no
9335 incompatibility since it never made sense with ordinary subclasses
9336 -- the failure just occurred later, with a more cumbersome
9337 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00009338

9346 given a unicode argument and os.listdir() returns unicode filenames.
9347
Georg Brandl3ee81df2008-05-17 18:14:43 +00009348- Patch #1673619: setup.py identifies extension modules it doesn't

9702 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009719- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009720 time so that opening a database previously created with the DB_DUP
9721 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9722 opens. Specifically: dictionary assignment to a DB object will
9723 replace all values for a given key when the database allows
9724 duplicate values. DB users should use DB.put(k, v) when they want
9725 to store duplicates; not DB[k] = v.

9732 characters with ASCII value less than 32. Also, it correctly quotes
9733 dots only if they occur on a single line, as opposed to the previous
9734 behavior of quoting dots if they are the second character of any
9735 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010118- Added case insensitive comparison methods ``PyOS_stricmp(char*,
