477
478- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
479 and later systems as is currently done for Python 3.x installers.
480 For 2.7.7 only, we will provide three installers:
481 the legacy deprecated 10.3+ 32-bit-only format;
482 the newer 10.5+ 32-bit-only format;
483 and the unchanged 10.6+ 64-/32-bit format.
484 Although binary installers will no longer be available from
485 python.org as of 2.7.8, it will still be possible to build from
486 source on 10.3.9 and 10.4 systems if necessary.
487 See Mac/BuildScript/README.txt for more information.

1866 32-bit-only installer Pythons on systems with Xcode 4 (currently
1867 OS X 10.8, 10.7, and optionally 10.6).
1868 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1869 * Since Xcode 4 removes ppc support, extension module builds now
1870 check for ppc compiler support and by default remove ppc and
1871 ppc64 archs when they are not available.
1872 * Extension module builds now revert to using system installed
1873 headers and libs (/usr and /System/Library) if the SDK used
1874 to build the interpreter is not installed or has moved.
1875 * Try to avoid building extension modules with deprecated
1876 and problematic Apple llvm-gcc compiler. If original compiler
1877 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01002308- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2309 Distutils-based packages with C extension modules may fail because
2310 Apple has removed gcc-4.2, the version used to build python.org
2311 64-bit/32-bit Pythons. If the user does not explicitly override
2312 the default C compiler by setting the CC environment variable,
2313 Distutils will now attempt to compile extension modules with clang
2314 if gcc-4.2 is required but not found. Also as a convenience, if
2315 the user does explicitly set CC, substitute its value as the default
2316 compiler in the Distutils LDSHARED configuration variable for OS X.
2317 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2318 SDK, neither of which are available in Xcode 4. This change does not

Ned Deily87e82bb2011-06-28 19:52:59 -07002569- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2570 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2571 interpreter process. This could cause failures in non-Distutils subprocesses
2572 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002573 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002574 deployment target only in the environment of each build subprocess. It is
2575 still possible to globally override the default by setting
2576 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2577 greater or equal to the default value, the value with which the interpreter
2578 was built.

2607 updating the check interval, so if the user decreases the check interval,
2608 the ticker doesn't have to wind down to zero from the old starting point
2609 before the new interval takes effect. And if the user increases the
2610 interval, it makes sure the new limit takes effect right away rather have an
2611 early task switch before recognizing the new interval.

3581 by Andrew Bennetts.

3590
Raymond Hettinger20397532010-09-12 02:11:45 +00003591- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3592 This prevents user-created self-referencing ordered dictionaries from
3593 becoming permanently uncollectable GC garbage. The downside is that
3594 removing __del__ means that the internal doubly-linked list has to wait for
3595 GC collection rather than freeing memory immediately when the refcnt drops
3596 to zero.
3597
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003598- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3601
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003602- Issue #9792: In case of connection failure, socket.create_connection()
3603 would swallow the exception and raise a new one, making it impossible
3604 to fetch the original errno, or to filter timeout errors. Now the
3605 original error is re-raised.
3606
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003607- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3608 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3609 be updated back after the system call. Original patch by Brian Brazil.

3616
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003617- Issue #808164: Fixed socket.close to avoid references to globals, to
3618 avoid issues when socket.close is called from a __del__ method.
3619

3621 can be set to False to turn off the previously undocumented 'popularity'
3622 heuristic. Patch by Terry Reedy and Eli Bendersky
3623
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003624- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3625 falling into recursion.
3626
R. David Murray7c4bf552010-08-25 01:45:57 +00003627- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3628 character years even if the message contains RFC822 two character years.
3629
Daniel Stutzbach91287322010-08-24 21:09:30 +00003630- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00003641- Issue #9214: Set operations on KeysView or ItemsView in the collections
3642 module now correctly return a set. (Patch by Eli Bendersky.)
3643
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003644- Issue #9617: Signals received during a low-level write operation aren't
3645 ignored by the buffered IO layer anymore.
3646
Benjamin Peterson52c36052010-08-21 03:03:22 +00003647- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3648 are not held onto after they are deleted elsewhere.
3649
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003650- Issue #9626: the view methods for collections.OrderedDict() were returning
3651 the unordered versions inherited from dict. Those methods are now
3652 overridden to provide ordered views.
3653
Éric Araujo0389ae62010-08-14 03:07:46 +00003654- Issue #8688: MANIFEST files created by distutils now include a magic
3655 comment indicating they are generated. Manually maintained MANIFESTs
3656 without this marker will not be overwritten or removed.
3657
Antoine Pitroue1436d12010-08-12 15:25:51 +00003658- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3659 and a BadZipfile error is raised if it doesn't match (as used to be the
3660 case in Python 2.5 and earlier).
3661
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003662- Issue #9550: a BufferedReader could issue an additional read when the
3663 original read request had been satisfied, which could block indefinitely
3664 when the underlying raw IO channel was e.g. a socket. Report and original
3665 patch by Jason V. Miller.
3666
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003667- Issue #9551: Don't raise TypeError when setting the value to None for

3686 This is how it is supposed to work, wget and curl do the same. Previous
3687 behavior was wrong.

3696 does not contain a '-', instead of raising an error.
3697

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004068- Issue #8748: Fix two issues with comparisons between complex and integer
4069 objects. (1) The comparison could incorrectly return True in some cases
4070 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4071 (2) The comparison raised an OverflowError for large integers, leading
4072 to unpredictable exceptions when combining integers and complex objects
4073 in sets or dicts.

4320 indefinitely if the other end didn't respond.
4321
Georg Brandlfee0f442010-05-22 21:26:21 +00004322- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandlfee0f442010-05-22 21:26:21 +00004455- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4456 with a non-empty format string. This is an effort to future-proof user
4457 code. If a derived class does not currently implement __format__ but later
4458 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004459 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004460 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004510- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4511 InvalidOperation instead of returning False. (Comparisons involving a quiet
4512 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4513 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004515- Issue #2531: Comparison operations between floats and Decimal instances now
4516 return a result based on the numeric values of the operands; previously they
4517 returned an arbitrary result based on the relative ordering of id(float) and
4518 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00004532- Comparisons using one of <, <=, >, >= between a complex instance and a
4533 Fractions instance now raise TypeError instead of returning True/False. This
4534 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4535 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004953 file position when calling `truncate()`. It would previously change the file
4954 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004955 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4956

4958 class used to represent files stored inside an archive. The new
4959 implementation is significantly faster and can be wrapped in a
4960 ``io.BufferedReader`` object for more speedups. It also solves an issue
4961 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4974 encoded string for them. This ensures that the upload and register commands
4975 send the correct values to PyPI without any error.

5050-----------------
5051
Georg Brandlba83f822010-03-14 09:50:54 +00005052- The ``__complex__()`` method is now looked up on the class of instances to
5053 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005054
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005055- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5056 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5057
Mark Dickinson1b34d252010-01-01 17:27:30 +00005058- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005059 DeprecationWarning when passed a float argument where an integer was expected.
5060 These functions and methods now raise TypeError instead. The majority of the
5061 effects of this change are in the extension modules, but some core functions
5062 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5063 and many unicode/str methods.

5075
Georg Brandlba83f822010-03-14 09:50:54 +00005076- Issue #1811: Improve accuracy and cross-platform consistency for true division
5077 of integers: the result of a/b is now correctly rounded for ints a and b (at
5078 least on IEEE 754 platforms), and in particular does not depend on the
5079 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00005086 executables on OSX.
5087
Georg Brandlba83f822010-03-14 09:50:54 +00005088 These executables now work properly with the arch(1) command: ``arch -ppc
5089 python`` will start a universal binary version of python in PPC mode (unlike
5090 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00005112 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00005252- Issue #7117: On almost all platforms: float-to-string and string-to-float
5253 conversions within Python are now correctly rounded. Places these conversions
5254 occur include: str for floats and complex numbers; the float and complex
5255 constructors; old-style and new-style numeric formatting; serialization and
5256 deserialization of floats and complex numbers using marshal, pickle and json;
5257 parsing of float and imaginary literals in Python code; Decimal-to-float
5258 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005259
Georg Brandlba83f822010-03-14 09:50:54 +00005260 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5261 providing correctly-rounded strtod and dtoa C functions. This code is
5262 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5263 the C compiler. There may be a small number of platforms on which correct
5264 operation of this code cannot be guaranteed, so the code is not used: notably,
5265 this applies to platforms where the C double format is not IEEE 754 binary64,
5266 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5267 and Python's configure script is unable to determine how to change the FPU
5268 precision. On these platforms conversions use the platform strtod and dtoa,
5269 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005271- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5272 uses the correctly-rounded string <-> float conversions described above (when
5273 available), and so produces correctly rounded results that will display nicely
5274 under the float repr. There are two related small changes: (1) round now
5275 accepts any class with an ``__index__()`` method for its second argument (but
5276 no longer accepts floats for the second argument), and (2) an excessively
5277 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5278 raises an exception.

6863 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6864 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6865 neither __int__ nor __long__, TypeError used to be raised (with a
6866 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6867 struct.error in other cases.

6870 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007064- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7066 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7067 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00007165 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7166 for catch_warnings() also led to an improvement in the raising of a
7167 DeprecationWarning related to warnings.warn_explicit().
7168

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007233What's New in Python 2.6 beta 3?
7234================================
7235
Barry Warsaw07a4a382008-08-21 01:15:08 +00007236*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007237
7238Core and Builtins
7239-----------------
7240
Guido van Rossumf8402962008-08-20 15:01:50 +00007241- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7242 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7243 extensions do not automatically benefit from the class attribute
7244 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7245 to their tp_flags field if they care. This is a backwards
7246 compatibility feature; in 3.0, all types will use the cache by
7247 default.
7248
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007249- Keyword arguments can now follow starred arguments. (``f(a, *args,
7250 keyword=23)`` is now valid syntax.)
7251
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007252- ctypes function pointers that are COM methods have a boolean True
7253 value again.
7254
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007255- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7256 by denying s# to parse objects that have a releasebuffer procedure,
7257 and introducing s*.
7258
Georg Brandl1e13ea92008-08-11 09:07:59 +00007259- Issue #3537: Fix an assertion failure when an empty but presized dict
7260 object was stored in the freelist.
7261
Mark Dickinsonb6467572008-08-04 21:30:09 +00007262- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7263 ValueError consistently across platforms.
7264
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007265- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7266 (64bit Unix, for example), unichr() would truncate its argument and return
7267 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7268
Neal Norwitze7d8be82008-07-31 17:17:14 +00007269- Apply security patches from Apple.
7270
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007271- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7272 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7273
Antoine Pitrou92f82162008-07-25 22:22:08 +00007274- Issue #1819: function calls with several named parameters are now on
7275 average 35% faster (as measured by pybench).
7276
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007277- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7278 the python debugger steps into a class statement: the free variables (local
7279 variables defined in an outer scope) would be deleted from the outer scope.
7280
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007281- Issue #2620: Overflow checking when allocating or reallocating memory
7282 was not always being done properly in some python types and extension
7283 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7284 all been updated to perform better checks and places in the code that
7285 would previously leak memory on the error path when such an allocation
7286 failed have been fixed.

7289-------
7290
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007291- Issue #3612: Added some missing basic types in ctypes.wintypes.
7292
Benjamin Petersone977ad42008-08-20 01:42:01 +00007293- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7294 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7295
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007296- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7297 version reported by these tools does not necessarily follow the python
7298 version numbering scheme, so the module is less strict when parsing it.
7299
Nick Coghlanf70385a2008-08-18 12:42:46 +00007300- Issue #2235: Added Py3k warnings for types which will become unhashable
7301 under the stricter __hash__ inheritance rules in 3.0. Several types
7302 which did not meet the rules for hash invariants and were already
7303 unhashable in 3.0 have now been explicitly flagged as unhashable in
7304 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7305 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7306
Brett Cannon88f801d2008-08-18 00:46:22 +00007307- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7308 imported into the module but exposed as part of the module's API.
7309
Brett Cannon7b96f072008-08-18 00:41:11 +00007310- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7311
Brett Cannon46225e72008-08-18 00:36:52 +00007312- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007314- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7315
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007316- Issue #3575: Incremental decoder's decode function now takes bytearray
7317 by using 's*' instead of 't#'.
7318
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007319- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007320 fails unicode conversion on 2nd parameter. (windows only)
7321
Georg Brandl222e2082010-08-01 22:27:39 +00007322- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007323 in a redirect.
7324
Brett Cannonabe423e2008-08-16 21:47:07 +00007325- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007326 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007327
Facundo Batistaeb90b782008-08-16 14:44:07 +00007328- Issue #2776: fixed small issue when handling an URL with double slash
7329 after a 302 response in the case of not going through a proxy.
7330
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007331- Issue #2676: in the email package, content-type parsing was hanging on
7332 pathological input because of quadratic or exponential behaviour of a
7333 regular expression.
7334
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007335- Issue #3476: binary buffered reading through the new "io" library is now
7336 thread-safe.
7337
Brett Cannonbf3157b2008-08-14 05:00:03 +00007338- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7339 since mimetools itself is deprecated. Because modules are cached, all
7340 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7341
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007342- Issue #3134: shutil referenced undefined WindowsError symbol.
7343
Robert Schuppenies14646332008-08-10 11:01:53 +00007344- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7345 menu entries were not deleted.
7346
Brett Cannon83e81842008-08-09 23:30:55 +00007347- Copied the implementation of reduce() to _functools.reduce() to have a
7348 version that did not raise a DeprecationWarning under -3.
7349
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007350- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7351 a MemoryError rather than silently stop the iteration.
7352
Guido van Rossum59ce9012008-08-09 14:55:34 +00007353- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7354 to _sre.compile() will now be rejected. This should not affect anybody
7355 since the re.compile() function never generates invalid re-bytecode.
7356
Skip Montanaroa032bf42008-08-08 22:52:51 +00007357- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7358 upon first access it can be automatically initialized from the csv file if
7359 it wasn't initialized during instantiation.
7360
Brett Cannon3aa2a492008-08-06 22:28:09 +00007361- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7362 the reload() built-in has been removed.
7363
Brett Cannon7e30b672008-08-04 21:52:25 +00007364- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007365 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007376 asking for a specific length. This problem only affected files opened
7377 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007378
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007379- Issue #3449: Update decimal module to use most recent specification
7380 (v. 1.68) and tests (v. 2.58) from IBM.

7429
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007430*Release date: 17-Jul-2008*

7433-----------------
7434
Georg Brandl3e483f62008-07-16 22:57:41 +00007435- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7436 its methods now allow for items objects that can be converted to
7437 an integer using operator.index().
7438
Mark Dickinson64b7e502008-07-16 09:40:03 +00007439- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7440 produced a ValueError instead of giving the correct float.
7441
Eric Smitha5fa5a22008-07-16 00:11:49 +00007442- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7443 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7444
Mark Dickinson7103aa42008-07-15 19:08:33 +00007445- Issue #3008: the float type has a new instance method 'float.hex'
7446 and a new class method 'float.fromhex' to convert floating-point
7447 numbers to and from hexadecimal strings, respectively.
7448
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007449- Issue #2235: __hash__ is once again inherited by default. To allow
7450 collections.Hashable to remain meaningful in the presence of the
7451 default hash implementation (object.__hash__), it is now possible
7452 to explicit block inheritance of hash by setting __hash__=None at
7453 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7454 level.
7455
Nick Coghlanb028f502008-07-13 14:52:36 +00007456- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7457 the parent module cannot be found while performing an absolute import.
7458 This means that an incorrectly defined __package__ attribute will
7459 now only prevent relative imports in that module rather than causing
7460 all imports from that module to fail.
7461
Nick Coghlan14ff9942008-07-08 14:21:42 +00007462- Issue #2517: Allow unicode messages in Exceptions again by correctly

7471 threading.local: the first member set by a thread could be saved in
7472 another thread's dictionary.
7473
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007474- Issue #3004: Minor change to slice.indices(): the start and stop
7475 arguments are now treated identically, making the behaviour easier
7476 to describe and understand. For example, slice(None, -10,
7477 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7478 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7479 10, -1).
7480
Georg Brandl278fc502008-07-19 12:46:12 +00007481- Issue #3219: Calling a function with repeated keyword arguments,
7482 f(a=2, a=23), would not cause a syntax error. This was a regression
7483 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007484
Georg Brandl278fc502008-07-19 12:46:12 +00007485- Issue #2862: Make int and float freelist management consistent with
7486 other freelists. Changes their CompactFreeList apis into
7487 ClearFreeList apis and calls them via gc.collect().

7493 api functions without holding the GIL, which could lead to a fatal
7494 error when they failed.
7495
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007496- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007521- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7522 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007523 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007524 content-length. The problem had been corrected in the 2.4 branch, but never
7525 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007540- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007992- Issue #1631171: Re-implement the 'warnings' module in C (the
7993 original Python code has been kept as backup). This will allow for
7994 using the 'warning's machinery in such places as the parser where
7995 use of pure Python code is not possible. Both the ``showarning()``
7996 and ``formatwarning()`` gain an optional 'line' argument which is
7997 not called by default for backwards-compatibility reasons. Setting
7998 ``warnings.showwarning()`` to an implementation that lacks support
7999 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008062- Issue #2550: The approach used by client/server code for obtaining
8063 ports to listen on in network-oriented tests has been refined in an
8064 effort to facilitate running multiple instances of the entire
8065 regression test suite in parallel without issue.
8066 test_support.bind_port() has been fixed such that it will always
8067 return a unique port -- which wasn't always the case with the
8068 previous implementation, especially if socket options had been set
8069 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8070 new implementation of bind_port() will actually raise an exception
8071 if it is passed an AF_INET/SOCK_STREAM socket with either the
8072 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8073 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8074 the socket it's been passed. This currently only applies to
8075 Windows. This option prevents any other sockets from binding to the
8076 host/port we've bound to, thus removing the possibility of the
8077 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8078 when a second SOCK_STREAM socket binds and accepts to a host/port
8079 that's already been bound by another socket. The optional preferred
8080 port parameter to bind_port() has been removed. Under no
8081 circumstances should tests be hard coding ports!
8082
8083 test_support.find_unused_port() has also been introduced, which will
8084 pass a temporary socket object to bind_port() in order to obtain an
8085 unused port. The temporary socket object is then closed and
8086 deleted, and the port is returned. This method should only be used
8087 for obtaining an unused port in order to pass to an external program
8088 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8089 a parameter to a server-oriented class that doesn't give you direct
8090 access to the underlying socket used.
8091
8092 Finally, test_support.HOST has been introduced, which should be used
8093 for the host argument of any relevant socket calls (i.e. bind and
8094 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008095
8096 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008097 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008098 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8099 test_asynchat and test_socket_ssl.
8100
Georg Brandl3ee81df2008-05-17 18:14:43 +00008101 It is now possible for multiple instances of the regression test
8102 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008381- Added the future_builtins module, which contains hex() and oct().
8382 These are the PEP 3127 version of these functions, designed to be
8383 compatible with the hex() and oct() builtins from Python 3.0. They
8384 differ slightly in their output formats from the existing, unchanged
8385 Python 2.6 builtins. The expected usage of the future_builtins
8386 module is:
8387 from future_builtins import hex, oct
8388
Eric Smith7ef40bf2008-02-20 23:34:22 +00008389- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8390 exponents for exponents with absolute value < 100. Follows C99
8391 standard. This is a change on Windows, which would use 3 digits.
8392 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8393 so that any alterations it does to the resulting string will be
8394 available in stringlib/formatter.h (for float.__format__).
8395
Eric Smith5a3c1352008-02-19 13:21:56 +00008396- Implemented PEP 3101, Advanced String Formatting. This adds a new
8397 builtin format(); a format() method for str and unicode; a
8398 __format__() method to object, str, unicode, int, long, float, and
8399 datetime; the class string.Formatter; and the C API
8400 PyObject_Format().
8401
Georg Brandl3ee81df2008-05-17 18:14:43 +00008402- Fixed several potential crashes, all caused by specially crafted
8403 __del__ methods exploiting objects in temporarily inconsistent
8404 state.

8415 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008416
Georg Brandl3ee81df2008-05-17 18:14:43 +00008417- Issue #2045: Fix an infinite recursion triggered when printing a
8418 subclass of collections.defaultdict, if its default_factory is set
8419 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008420
Christian Heimesf75dbef2008-02-08 00:11:31 +00008421- Fixed a minor memory leak in dictobject.c. The content of the free

8430
Georg Brandl3ee81df2008-05-17 18:14:43 +00008431- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8432 calls. Python expected the return type int but the fork familie
8433 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008447- Patch #1473257: generator objects gain a gi_code attribute. This is
8448 the same object as the func_code attribute of the function that
8449 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008450
Georg Brandl3ee81df2008-05-17 18:14:43 +00008451- Issue #1920: "while 0" statements were completely removed by the
8452 compiler, even in the presence of an "else" clause, which is
8453 supposed to be run when the condition is false. Now the compiler
8454 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008455

Georg Brandl14404b62008-01-19 19:27:05 +00008471- Issue #1679: "0x" was taken as a valid integer literal.
8472
Georg Brandl6caad7d2008-01-26 14:19:22 +00008473- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008474 added.
8475
Christian Heimesc94e2b52008-01-14 04:13:37 +00008476- sys.float_info / PyFloat_GetInfo: The floating point information
8477 object was converted from a dict to a specialized structseq object.
8478
Georg Brandl3ee81df2008-05-17 18:14:43 +00008479- Patch #1816: Added sys.flags structseq. It exposes the status of
8480 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008481
Georg Brandl3ee81df2008-05-17 18:14:43 +00008482- Objects/structseq.c: Implemented new structseq representation. The
8483 patch makes structseqs (e.g. the return value of os.stat) more
8484 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008485
Georg Brandl3ee81df2008-05-17 18:14:43 +00008486- Patch #1700288: added a type attribute cache that caches method
8487 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008488
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008489- Bug #1776: __import__() no longer accepts filenames on any platform.
8490 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008491
Georg Brandlaed6c662008-01-07 17:25:53 +00008492- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8493
Georg Brandl3ee81df2008-05-17 18:14:43 +00008494- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8495 envvar and sys.dont_write_bytecode attribute. All these can be set
8496 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008497
Georg Brandl3ee81df2008-05-17 18:14:43 +00008498- Improve some exception messages when Windows fails to load an
8499 extension module. Now we get for example '%1 is not a valid Win32
8500 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008501

Georg Brandl3ee81df2008-05-17 18:14:43 +00008504- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8505 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008506
Christian Heimes0a8143f2007-12-18 23:22:54 +00008507- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008508 and INF. float("nan"), float("inf") and float("-inf") now work on
8509 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008510
Georg Brandl3ee81df2008-05-17 18:14:43 +00008511- Compiler now generates simpler and faster code for dictionary
8512 literals. The oparg for BUILD_MAP now indicates an estimated
8513 dictionary size. There is a new opcode, STORE_MAP, for adding
8514 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008543- Patch #1739468: Directories and zipfiles containing a __main__.py
8544 file can now be directly executed by passing their name to the
8545 interpreter. The directory/zipfile is automatically inserted as the
8546 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008547
Georg Brandl3ee81df2008-05-17 18:14:43 +00008548- Issue #1265: Fix a problem with sys.settrace, if the tracing
8549 function uses a generator expression when at the same time the
8550 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008551
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008552- sets and frozensets now have an isdisjoint() method.
8553
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008554- optimize the performance of builtin.sum().
8555
Neal Norwitz44f326e2007-10-05 05:29:17 +00008556- Fix warnings found by the new version of the Coverity checker.
8557
Georg Brandl21e99f42010-03-07 15:23:59 +00008558- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008559 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8560 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008561
Georg Brandl3ee81df2008-05-17 18:14:43 +00008562- Issue #1686386: Tuple's tp_repr did not take into account the
8563 possibility of having a self-referential tuple, which is possible
8564 from C code. Nor did object's tp_str consider that a type's tp_str
8565 could do something that could lead to an inifinite recursion.
8566 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8567 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008568
Georg Brandl3ee81df2008-05-17 18:14:43 +00008569- Issue #1164: It was possible to trigger deadlock when using the
8570 'print' statement to write to a file since the GIL was not released
8571 as needed. Now PyObject_Print() does the right thing along with
8572 various tp_print implementations of the built-in types and those in
8573 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008574
Georg Brandl3ee81df2008-05-17 18:14:43 +00008575- Issue #1147: Exceptions were directly allowing string exceptions in
8576 their throw() method even though string exceptions no longer
8577 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008578
Georg Brandl3ee81df2008-05-17 18:14:43 +00008579- Issue #1096: Prevent a segfault from getting the repr of a very
8580 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008581
Brett Cannon1e534b52007-09-07 04:18:30 +00008582- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008583 PyObject_Call() never calling back out to Python code to trigger
8584 recursion depth updates/checks. Required the creation of a static
8585 RuntimeError instance in case normalizing an exception put the
8586 recursion check value past its limit. Fixes crashers
8587 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008588
Georg Brandl3ee81df2008-05-17 18:14:43 +00008589- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008602- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008603 __*__ attributes. (Some already existed, e.g., __doc__ and
8604 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008605
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008606- Add -3 option to the interpreter to warn about features that are
8607 deprecated and will be changed/removed in Python 3.0.
8608
Georg Brandl2134e752007-05-21 20:34:16 +00008609- Patch #1686487: you can now pass any mapping after '**' in function
8610 calls.
8611
Collin Winter62903052007-05-18 23:11:24 +00008612- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008613 "except E as target:". This is to provide forwards compatibility
8614 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008615
Brett Cannon229cee22007-05-05 01:34:02 +00008616- Deprecate BaseException.message as per PEP 352.
8617
Georg Brandl3ee81df2008-05-17 18:14:43 +00008618- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008619 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008620
Vinay Sajip8549ce32007-05-06 17:53:37 +00008621- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008622 setting a plain string, ie don't expand to single letter identifiers.
8623
Raymond Hettinger13936692007-04-11 18:40:58 +00008624- Request #1191699: Slices can now be pickled.
8625
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008626- Request #1193128: str.translate() now allows a None argument for
8627 translations that only remove characters without re-mapping the
8628 remaining characters.
8629
Georg Brandl5cb76c12007-03-21 09:00:39 +00008630- Patch #1682205: a TypeError while unpacking an iterable is no longer
8631 masked by a generic one with the message "unpack non-sequence".
8632
Neal Norwitzaa754b72007-03-21 06:39:48 +00008633- Remove unused file Python/fmod.c.
8634
Guido van Rossum143b5642007-03-23 04:58:42 +00008635- Bug #1683368: The object.__init__() and object.__new__() methods are
8636 now stricter in rejecting excess arguments. The only time when
8637 either allows excess arguments is when it is not overridden and the
8638 other one is. For backwards compatibility, when both are
8639 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008640 warning later). Also, type.__init__() insists on the same signature
8641 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008642
Georg Brandl3ee81df2008-05-17 18:14:43 +00008643- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8644 object to complex using its __complex__() method before falling back
8645 to the __float__() method. Therefore, the functions in the cmath
8646 module now can operate on objects that define a __complex__()
8647 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008648
Georg Brandl3ee81df2008-05-17 18:14:43 +00008649- Patch #1623563: allow __class__ assignment for classes with
8650 __slots__. The old and the new class are still required to have the
8651 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008652
Georg Brandl3ee81df2008-05-17 18:14:43 +00008653- Patch #1642547: Fix an error/crash when encountering syntax errors

8657 ``object.__reduce_ex__()`` is called with an object that is faking
8658 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008659
Georg Brandl3ee81df2008-05-17 18:14:43 +00008660- Patch #1680015: Don't modify __slots__ tuple if it contains an

8664
Georg Brandl7b9c5552007-03-12 14:30:05 +00008665- Bug #1678647: write a newline after printing an exception in any
8666 case, even when converting the value to a string failed.
8667
Georg Brandl871f1bc2007-03-12 13:17:36 +00008668- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008669 its argument, if it exists. If not, it will work like before. This
8670 allows customizing the output of dir() in the presence of a
8671 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00008673- Patch #922167: Python no longer segfaults when faced with infinitely
8674 self-recursive reload() calls (as reported by bug #742342).
8675
Georg Brandl3ee81df2008-05-17 18:14:43 +00008676- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00008679- Patch #1491866: change the complex() constructor to allow
8680 parthensized forms. This means complex(repr(x)) now works instead of
8681 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008682
Georg Brandlaa2321b2007-03-07 00:40:28 +00008683- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008684 makes the filenames the warning module prints much more sensible
8685 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008686
Georg Brandl49aafc92007-03-07 00:34:46 +00008687- Variant of patch #697613: don't exit the interpreter on a SystemExit
8688 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008689 variable is given, but break into the interactive interpreter just
8690 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008698- Patch #1674228: when assigning a slice (old-style), check for the
8699 sq_ass_slice instead of the sq_slice slot.
8700
Georg Brandl3ee81df2008-05-17 18:14:43 +00008701- When printing an unraisable error, don't print exceptions. before
8702 the name. This duplicates the behavior whening normally printing
8703 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009204- Added a timeout parameter to the constructor of other protocols
9205 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9206 work started with create_connection() and timeout in httplib, and
9207 closes patch #723312.
9208
Vinay Sajip8549ce32007-05-06 17:53:37 +00009209- Patch #1676823: Added create_connection() to socket.py, which may be

9233
Georg Brandlf66b6032007-03-14 08:27:52 +00009234- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00009235 AttributeError instead of an IOError when the server's response
9236 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009237
Georg Brandl3ee81df2008-05-17 18:14:43 +00009238- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00009242- Patch #1429539: pdb now correctly initializes the __main__ module
9243 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009244 correctly now.
9245

9252
Georg Brandl3ee81df2008-05-17 18:14:43 +00009253- Patch #1530482: add pydoc.render_doc() which returns the

9263 parameter which can be set to False to prevent the default
9264 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00009266- Patch #1581073: add a flag to textwrap that prevents the dropping of
9267 whitespace while wrapping.
9268
Georg Brandl92a6bae2007-03-13 17:43:32 +00009269- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009270 are set for invalid interpolation sequences that would lead to
9271 errors on reading back those values.

9314 returned string up to the first NUL character.

9325
Georg Brandl3ee81df2008-05-17 18:14:43 +00009326- unittest now verifies more of its assumptions. In particular,
9327 TestCase and TestSuite subclasses (not instances) are no longer
9328 accepted in TestSuite.addTest(). This should cause no
9329 incompatibility since it never made sense with ordinary subclasses
9330 -- the failure just occurred later, with a more cumbersome
9331 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00009332

9341
Georg Brandl3ee81df2008-05-17 18:14:43 +00009342- Patch #1673619: setup.py identifies extension modules it doesn't

9696 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9697 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009713- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009714 time so that opening a database previously created with the DB_DUP
9715 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9716 opens. Specifically: dictionary assignment to a DB object will
9717 replace all values for a given key when the database allows
9718 duplicate values. DB users should use DB.put(k, v) when they want
9719 to store duplicates; not DB[k] = v.

9726 characters with ASCII value less than 32. Also, it correctly quotes
9727 dots only if they occur on a single line, as opposed to the previous
9728 behavior of quoting dots if they are the second character of any
9729 line.
