Florent Xiclunac2279652012-02-12 14:49:03 +0100313- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100314 has left two versions of customize_compiler, the original in
315 distutils.sysconfig and another copy in distutils.ccompiler, with some
316 parts of distutils calling one and others using the other.
317 Complete the revert back to only having one in distutils.sysconfig as
318 is the case in 3.x.
319
Ned Deily0d0ea482012-02-10 12:59:06 +0100320- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
321 Distutils-based packages with C extension modules may fail because
322 Apple has removed gcc-4.2, the version used to build python.org
323 64-bit/32-bit Pythons. If the user does not explicitly override
324 the default C compiler by setting the CC environment variable,
325 Distutils will now attempt to compile extension modules with clang
326 if gcc-4.2 is required but not found. Also as a convenience, if
327 the user does explicitly set CC, substitute its value as the default
328 compiler in the Distutils LDSHARED configuration variable for OS X.
329 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
330 SDK, neither of which are available in Xcode 4. This change does not
331 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700604- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
605 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
606 interpreter process. This could cause failures in non-Distutils subprocesses
607 and was unreliable since tests or user programs could modify the interpreter
608 environment after Distutils set it. Instead, have Distutils set the the
609 deployment target only in the environment of each build subprocess. It is
610 still possible to globally override the default by setting
611 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
612 greater or equal to the default value, the value with which the interpreter
613 was built.

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

Raymond Hettinger20397532010-09-12 02:11:45 +00001590- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1591 This prevents user-created self-referencing ordered dictionaries from
1592 becoming permanently uncollectable GC garbage. The downside is that
1593 removing __del__ means that the internal doubly-linked list has to wait for
1594 GC collection rather than freeing memory immediately when the refcnt drops
1595 to zero.

1603 to fetch the original errno, or to filter timeout errors. Now the
1604 original error is re-raised.

1625
R. David Murray7c4bf552010-08-25 01:45:57 +00001626- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1627 character years even if the message contains RFC822 two character years.
1628
Daniel Stutzbach91287322010-08-24 21:09:30 +00001629- Issue #8750: Fixed MutableSet's methods to correctly handle

1642
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001643- Issue #9617: Signals received during a low-level write operation aren't

1645
Benjamin Peterson52c36052010-08-21 03:03:22 +00001646- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1648
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001649- Issue #9626: the view methods for collections.OrderedDict() were returning

1659 case in Python 2.5 and earlier).
1660
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001661- Issue #9550: a BufferedReader could issue an additional read when the

1663 when the underlying raw IO channel was e.g. a socket. Report and original
1664 patch by Jason V. Miller.

2058 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2059 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2060 Previous versions returned a single u'\ufffd'.

2070 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

2320 indefinitely if the other end didn't respond.
2321
Georg Brandlfee0f442010-05-22 21:26:21 +00002322- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002415 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

2441
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002442- Issue #8329: Don't return the same lists from select.select when no fds are
2443 changed.
2444
Georg Brandlfee0f442010-05-22 21:26:21 +00002445- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

Georg Brandlfee0f442010-05-22 21:26:21 +00002455- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2456 with a non-empty format string. This is an effort to future-proof user
2457 code. If a derived class does not currently implement __format__ but later
2458 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002459 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002460 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002510- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2511 InvalidOperation instead of returning False. (Comparisons involving a quiet
2512 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2513 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00002515- Issue #2531: Comparison operations between floats and Decimal instances now
2516 return a result based on the numeric values of the operands; previously they

2518 id(Decimal).

2533 Fractions instance now raise TypeError instead of returning True/False. This
2534 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2535 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002953 file position when calling `truncate()`. It would previously change the file
2954 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002955 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2958 class used to represent files stored inside an archive. The new
2959 implementation is significantly faster and can be wrapped in a

2961 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3051
Georg Brandlba83f822010-03-14 09:50:54 +00003052- The ``__complex__()`` method is now looked up on the class of instances to
3053 make it consistent with other special methods.

3057
Mark Dickinson1b34d252010-01-01 17:27:30 +00003058- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003059 DeprecationWarning when passed a float argument where an integer was expected.
3060 These functions and methods now raise TypeError instead. The majority of the
3061 effects of this change are in the extension modules, but some core functions
3062 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3063 and many unicode/str methods.

3075
Georg Brandlba83f822010-03-14 09:50:54 +00003076- Issue #1811: Improve accuracy and cross-platform consistency for true division
3077 of integers: the result of a/b is now correctly rounded for ints a and b (at
3078 least on IEEE 754 platforms), and in particular does not depend on the
3079 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00003086 executables on OSX.
3087
Georg Brandlba83f822010-03-14 09:50:54 +00003088 These executables now work properly with the arch(1) command: ``arch -ppc
3089 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003113 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00003253- Issue #7117: On almost all platforms: float-to-string and string-to-float
3254 conversions within Python are now correctly rounded. Places these conversions
3255 occur include: str for floats and complex numbers; the float and complex
3256 constructors; old-style and new-style numeric formatting; serialization and
3257 deserialization of floats and complex numbers using marshal, pickle and json;
3258 parsing of float and imaginary literals in Python code; Decimal-to-float
3259 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003260
Georg Brandlba83f822010-03-14 09:50:54 +00003261 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3262 providing correctly-rounded strtod and dtoa C functions. This code is
3263 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3264 the C compiler. There may be a small number of platforms on which correct
3265 operation of this code cannot be guaranteed, so the code is not used: notably,
3266 this applies to platforms where the C double format is not IEEE 754 binary64,
3267 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3268 and Python's configure script is unable to determine how to change the FPU
3269 precision. On these platforms conversions use the platform strtod and dtoa,
3270 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003272- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3273 uses the correctly-rounded string <-> float conversions described above (when
3274 available), and so produces correctly rounded results that will display nicely
3275 under the float repr. There are two related small changes: (1) round now
3276 accepts any class with an ``__index__()`` method for its second argument (but
3277 no longer accepts floats for the second argument), and (2) an excessively
3278 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3279 raises an exception.

4861 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4862 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4863 neither __int__ nor __long__, TypeError used to be raised (with a

4868 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005062- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5064 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5065 ``printf`` function, whereas PyString_FromFormat has an independent
5066 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005163 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5164 for catch_warnings() also led to an improvement in the raising of a
5165 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005231What's New in Python 2.6 beta 3?
5232================================
5233
Barry Warsaw07a4a382008-08-21 01:15:08 +00005234*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005235
5236Core and Builtins
5237-----------------
5238
Guido van Rossumf8402962008-08-20 15:01:50 +00005239- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5240 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5241 extensions do not automatically benefit from the class attribute
5242 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5243 to their tp_flags field if they care. This is a backwards
5244 compatibility feature; in 3.0, all types will use the cache by
5245 default.
5246
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005247- Keyword arguments can now follow starred arguments. (``f(a, *args,
5248 keyword=23)`` is now valid syntax.)
5249
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005250- ctypes function pointers that are COM methods have a boolean True
5251 value again.
5252
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005253- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5254 by denying s# to parse objects that have a releasebuffer procedure,
5255 and introducing s*.
5256
Georg Brandl1e13ea92008-08-11 09:07:59 +00005257- Issue #3537: Fix an assertion failure when an empty but presized dict
5258 object was stored in the freelist.
5259
Mark Dickinsonb6467572008-08-04 21:30:09 +00005260- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5261 ValueError consistently across platforms.
5262
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005263- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5264 (64bit Unix, for example), unichr() would truncate its argument and return
5265 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5266
Neal Norwitze7d8be82008-07-31 17:17:14 +00005267- Apply security patches from Apple.
5268
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005269- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5270 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5271
Antoine Pitrou92f82162008-07-25 22:22:08 +00005272- Issue #1819: function calls with several named parameters are now on
5273 average 35% faster (as measured by pybench).
5274
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005275- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5276 the python debugger steps into a class statement: the free variables (local
5277 variables defined in an outer scope) would be deleted from the outer scope.
5278
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005279- Issue #2620: Overflow checking when allocating or reallocating memory
5280 was not always being done properly in some python types and extension
5281 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5282 all been updated to perform better checks and places in the code that
5283 would previously leak memory on the error path when such an allocation
5284 failed have been fixed.

5287-------
5288
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005289- Issue #3612: Added some missing basic types in ctypes.wintypes.
5290
Benjamin Petersone977ad42008-08-20 01:42:01 +00005291- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5292 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5293
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005294- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5295 version reported by these tools does not necessarily follow the python
5296 version numbering scheme, so the module is less strict when parsing it.
5297
Nick Coghlanf70385a2008-08-18 12:42:46 +00005298- Issue #2235: Added Py3k warnings for types which will become unhashable
5299 under the stricter __hash__ inheritance rules in 3.0. Several types
5300 which did not meet the rules for hash invariants and were already
5301 unhashable in 3.0 have now been explicitly flagged as unhashable in
5302 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5303 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5304
Brett Cannon88f801d2008-08-18 00:46:22 +00005305- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5306 imported into the module but exposed as part of the module's API.
5307
Brett Cannon7b96f072008-08-18 00:41:11 +00005308- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5309
Brett Cannon46225e72008-08-18 00:36:52 +00005310- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005312- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5313
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005314- Issue #3575: Incremental decoder's decode function now takes bytearray
5315 by using 's*' instead of 't#'.
5316
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005317- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005318 fails unicode conversion on 2nd parameter. (windows only)
5319
Georg Brandl222e2082010-08-01 22:27:39 +00005320- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005321 in a redirect.
5322
Brett Cannonabe423e2008-08-16 21:47:07 +00005323- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005324 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005325
Facundo Batistaeb90b782008-08-16 14:44:07 +00005326- Issue #2776: fixed small issue when handling an URL with double slash
5327 after a 302 response in the case of not going through a proxy.
5328
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005329- Issue #2676: in the email package, content-type parsing was hanging on
5330 pathological input because of quadratic or exponential behaviour of a
5331 regular expression.
5332
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005333- Issue #3476: binary buffered reading through the new "io" library is now
5334 thread-safe.
5335
Brett Cannonbf3157b2008-08-14 05:00:03 +00005336- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5337 since mimetools itself is deprecated. Because modules are cached, all
5338 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5339
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005340- Issue #3134: shutil referenced undefined WindowsError symbol.
5341
Robert Schuppenies14646332008-08-10 11:01:53 +00005342- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5343 menu entries were not deleted.
5344
Brett Cannon83e81842008-08-09 23:30:55 +00005345- Copied the implementation of reduce() to _functools.reduce() to have a
5346 version that did not raise a DeprecationWarning under -3.
5347
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005348- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5349 a MemoryError rather than silently stop the iteration.
5350
Guido van Rossum59ce9012008-08-09 14:55:34 +00005351- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5352 to _sre.compile() will now be rejected. This should not affect anybody
5353 since the re.compile() function never generates invalid re-bytecode.
5354
Skip Montanaroa032bf42008-08-08 22:52:51 +00005355- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5356 upon first access it can be automatically initialized from the csv file if
5357 it wasn't initialized during instantiation.
5358
Brett Cannon3aa2a492008-08-06 22:28:09 +00005359- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5360 the reload() built-in has been removed.
5361
Brett Cannon7e30b672008-08-04 21:52:25 +00005362- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005363 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005374 asking for a specific length. This problem only affected files opened
5375 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005376

5403
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005404- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

5418
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005419- Issue #643841: The language reference now provides more detailed

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005425What's New in Python 2.6 beta 2?
5426================================
5427
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005428*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005430Core and Builtins
5431-----------------
5432
Georg Brandl3e483f62008-07-16 22:57:41 +00005433- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5434 its methods now allow for items objects that can be converted to
5435 an integer using operator.index().
5436
Mark Dickinson64b7e502008-07-16 09:40:03 +00005437- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5438 produced a ValueError instead of giving the correct float.
5439
Eric Smitha5fa5a22008-07-16 00:11:49 +00005440- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5441 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5442
Mark Dickinson7103aa42008-07-15 19:08:33 +00005443- Issue #3008: the float type has a new instance method 'float.hex'
5444 and a new class method 'float.fromhex' to convert floating-point
5445 numbers to and from hexadecimal strings, respectively.
5446
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005447- Issue #2235: __hash__ is once again inherited by default. To allow
5448 collections.Hashable to remain meaningful in the presence of the
5449 default hash implementation (object.__hash__), it is now possible
5450 to explicit block inheritance of hash by setting __hash__=None at
5451 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5452 level.
5453
Nick Coghlanb028f502008-07-13 14:52:36 +00005454- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5455 the parent module cannot be found while performing an absolute import.
5456 This means that an incorrectly defined __package__ attribute will
5457 now only prevent relative imports in that module rather than causing
5458 all imports from that module to fail.
5459
Nick Coghlan14ff9942008-07-08 14:21:42 +00005460- Issue #2517: Allow unicode messages in Exceptions again by correctly
5461 bypassing the instance dictionary when looking up __unicode__ on
5462 new-style classes.
5463
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005464- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5465 set to a custom object whose write() method happens to install
5466 another file in sys.stdout.
5467
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005468- Issue #3088: Corrected a race condition in classes derived from
5469 threading.local: the first member set by a thread could be saved in
5470 another thread's dictionary.
5471
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005472- Issue #3004: Minor change to slice.indices(): the start and stop
5473 arguments are now treated identically, making the behaviour easier
5474 to describe and understand. For example, slice(None, -10,
5475 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5476 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5477 10, -1).
5478
Georg Brandl278fc502008-07-19 12:46:12 +00005479- Issue #3219: Calling a function with repeated keyword arguments,
5480 f(a=2, a=23), would not cause a syntax error. This was a regression
5481 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005482
Georg Brandl278fc502008-07-19 12:46:12 +00005483- Issue #2862: Make int and float freelist management consistent with
5484 other freelists. Changes their CompactFreeList apis into
5485 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00005490- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5491 api functions without holding the GIL, which could lead to a fatal
5492 error when they failed.
5493
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005494- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5503 ForkingPickler.register() to resolve conflict with ctypes.
5504
Vinay Sajip51e65192008-07-18 09:01:10 +00005505- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005506
Thomas Heller880f5292008-07-15 19:39:38 +00005507- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5508 a valid dlerror() message.

Thomas Heller2bad6572008-07-15 17:19:50 +00005510- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5511 incomplete structure was created.

5516
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005517- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005518
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005519- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5520 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005521 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005522 content-length. The problem had been corrected in the 2.4 branch, but never
5523 merged into trunk.
5524
Georg Brandle78fbcc2008-07-05 10:13:36 +00005525- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005538- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5539 handling is now the same as that of other special attributes like __name__).
5540
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005541- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5998 not called by default for backwards-compatibility reasons. Setting
5999 ``warnings.showwarning()`` to an implementation that lacks support
6000 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006063- Issue #2550: The approach used by client/server code for obtaining
6064 ports to listen on in network-oriented tests has been refined in an
6065 effort to facilitate running multiple instances of the entire
6066 regression test suite in parallel without issue.
6067 test_support.bind_port() has been fixed such that it will always
6068 return a unique port -- which wasn't always the case with the
6069 previous implementation, especially if socket options had been set
6070 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6071 new implementation of bind_port() will actually raise an exception
6072 if it is passed an AF_INET/SOCK_STREAM socket with either the
6073 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6074 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6075 the socket it's been passed. This currently only applies to
6076 Windows. This option prevents any other sockets from binding to the
6077 host/port we've bound to, thus removing the possibility of the
6078 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6079 when a second SOCK_STREAM socket binds and accepts to a host/port
6080 that's already been bound by another socket. The optional preferred
6081 port parameter to bind_port() has been removed. Under no
6082 circumstances should tests be hard coding ports!
6083
6084 test_support.find_unused_port() has also been introduced, which will
6085 pass a temporary socket object to bind_port() in order to obtain an
6086 unused port. The temporary socket object is then closed and
6087 deleted, and the port is returned. This method should only be used
6088 for obtaining an unused port in order to pass to an external program
6089 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6090 a parameter to a server-oriented class that doesn't give you direct
6091 access to the underlying socket used.
6092
6093 Finally, test_support.HOST has been introduced, which should be used
6094 for the host argument of any relevant socket calls (i.e. bind and
6095 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006096
6097 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006098 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006099 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6100 test_asynchat and test_socket_ssl.

6103 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006382- Added the future_builtins module, which contains hex() and oct().
6383 These are the PEP 3127 version of these functions, designed to be
6384 compatible with the hex() and oct() builtins from Python 3.0. They
6385 differ slightly in their output formats from the existing, unchanged
6386 Python 2.6 builtins. The expected usage of the future_builtins
6387 module is:
6388 from future_builtins import hex, oct
6389
Eric Smith7ef40bf2008-02-20 23:34:22 +00006390- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6391 exponents for exponents with absolute value < 100. Follows C99
6392 standard. This is a change on Windows, which would use 3 digits.
6393 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6394 so that any alterations it does to the resulting string will be
6395 available in stringlib/formatter.h (for float.__format__).
6396
Eric Smith5a3c1352008-02-19 13:21:56 +00006397- Implemented PEP 3101, Advanced String Formatting. This adds a new
6398 builtin format(); a format() method for str and unicode; a
6399 __format__() method to object, str, unicode, int, long, float, and
6400 datetime; the class string.Formatter; and the C API
6401 PyObject_Format().
6402
Georg Brandl3ee81df2008-05-17 18:14:43 +00006403- Fixed several potential crashes, all caused by specially crafted
6404 __del__ methods exploiting objects in temporarily inconsistent
6405 state.

6416 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006417
Georg Brandl3ee81df2008-05-17 18:14:43 +00006418- Issue #2045: Fix an infinite recursion triggered when printing a
6419 subclass of collections.defaultdict, if its default_factory is set
6420 to a bound method.

6431
Georg Brandl3ee81df2008-05-17 18:14:43 +00006432- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

6434 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006448- Patch #1473257: generator objects gain a gi_code attribute. This is
6449 the same object as the func_code attribute of the function that
6450 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006451
Georg Brandl3ee81df2008-05-17 18:14:43 +00006452- Issue #1920: "while 0" statements were completely removed by the
6453 compiler, even in the presence of an "else" clause, which is
6454 supposed to be run when the condition is false. Now the compiler
6455 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006456

Georg Brandl3ee81df2008-05-17 18:14:43 +00006480- Patch #1816: Added sys.flags structseq. It exposes the status of
6481 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006482
Georg Brandl3ee81df2008-05-17 18:14:43 +00006483- Objects/structseq.c: Implemented new structseq representation. The
6484 patch makes structseqs (e.g. the return value of os.stat) more
6485 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006486
Georg Brandl3ee81df2008-05-17 18:14:43 +00006487- Patch #1700288: added a type attribute cache that caches method
6488 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006489
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006490- Bug #1776: __import__() no longer accepts filenames on any platform.
6491 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006492
Georg Brandlaed6c662008-01-07 17:25:53 +00006493- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6494
Georg Brandl3ee81df2008-05-17 18:14:43 +00006495- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6496 envvar and sys.dont_write_bytecode attribute. All these can be set
6497 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006498
Georg Brandl3ee81df2008-05-17 18:14:43 +00006499- Improve some exception messages when Windows fails to load an
6500 extension module. Now we get for example '%1 is not a valid Win32
6501 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006502
Georg Brandl3ee81df2008-05-17 18:14:43 +00006503- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006505- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6506 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006507
Christian Heimes0a8143f2007-12-18 23:22:54 +00006508- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006509 and INF. float("nan"), float("inf") and float("-inf") now work on
6510 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006511
Georg Brandl3ee81df2008-05-17 18:14:43 +00006512- Compiler now generates simpler and faster code for dictionary
6513 literals. The oparg for BUILD_MAP now indicates an estimated
6514 dictionary size. There is a new opcode, STORE_MAP, for adding
6515 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006516
Georg Brandl3ee81df2008-05-17 18:14:43 +00006517- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006519- Issue #1620: New property decorator syntax was modifying the
6520 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006521
Georg Brandl3ee81df2008-05-17 18:14:43 +00006522- Issue #1538: Avoid copying string in split/rsplit if the split char
6523 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006524
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006525- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006526 SystemError.
6527
Nick Coghlanef01d822007-12-03 12:55:17 +00006528- PEP 366: Allow explicit relative imports when executing modules
6529 inside packages with the -m switch via a new module level
6530 __package__ attribute.

6533 running, and if the deallocation of its frames somehow calls the
6534 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006535

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006539 attribute of an empty cell object.
6540
Georg Brandl3ee81df2008-05-17 18:14:43 +00006541- Issue #1460: The utf-7 incremental decoder did not accept truncated
6542 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006543
Georg Brandl3ee81df2008-05-17 18:14:43 +00006544- Patch #1739468: Directories and zipfiles containing a __main__.py
6545 file can now be directly executed by passing their name to the
6546 interpreter. The directory/zipfile is automatically inserted as the
6547 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006548
Georg Brandl3ee81df2008-05-17 18:14:43 +00006549- Issue #1265: Fix a problem with sys.settrace, if the tracing
6550 function uses a generator expression when at the same time the
6551 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006552
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006553- sets and frozensets now have an isdisjoint() method.
6554
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006555- optimize the performance of builtin.sum().
6556
Neal Norwitz44f326e2007-10-05 05:29:17 +00006557- Fix warnings found by the new version of the Coverity checker.
6558
Georg Brandl21e99f42010-03-07 15:23:59 +00006559- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006560 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6561 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006562
Georg Brandl3ee81df2008-05-17 18:14:43 +00006563- Issue #1686386: Tuple's tp_repr did not take into account the
6564 possibility of having a self-referential tuple, which is possible
6565 from C code. Nor did object's tp_str consider that a type's tp_str
6566 could do something that could lead to an inifinite recursion.
6567 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6568 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006569
Georg Brandl3ee81df2008-05-17 18:14:43 +00006570- Issue #1164: It was possible to trigger deadlock when using the
6571 'print' statement to write to a file since the GIL was not released
6572 as needed. Now PyObject_Print() does the right thing along with
6573 various tp_print implementations of the built-in types and those in
6574 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006575
Georg Brandl3ee81df2008-05-17 18:14:43 +00006576- Issue #1147: Exceptions were directly allowing string exceptions in
6577 their throw() method even though string exceptions no longer
6578 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006579
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580- Issue #1096: Prevent a segfault from getting the repr of a very
6581 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006582
Brett Cannon1e534b52007-09-07 04:18:30 +00006583- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006584 PyObject_Call() never calling back out to Python code to trigger
6585 recursion depth updates/checks. Required the creation of a static
6586 RuntimeError instance in case normalizing an exception put the
6587 recursion check value past its limit. Fixes crashers
6588 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006589
Georg Brandl3ee81df2008-05-17 18:14:43 +00006590- Patch #1031213: Decode source line in SyntaxErrors back to its

6594 with %G.
6595
Georg Brandl3ee81df2008-05-17 18:14:43 +00006596- Prevent expandtabs() on string and unicode objects from causing a
6597 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006603- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006604 __*__ attributes. (Some already existed, e.g., __doc__ and
6605 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006606
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006607- Add -3 option to the interpreter to warn about features that are
6608 deprecated and will be changed/removed in Python 3.0.
6609
Georg Brandl2134e752007-05-21 20:34:16 +00006610- Patch #1686487: you can now pass any mapping after '**' in function
6611 calls.
6612
Collin Winter62903052007-05-18 23:11:24 +00006613- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006614 "except E as target:". This is to provide forwards compatibility
6615 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006616
Brett Cannon229cee22007-05-05 01:34:02 +00006617- Deprecate BaseException.message as per PEP 352.
6618
Georg Brandl3ee81df2008-05-17 18:14:43 +00006619- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006620 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006621
Vinay Sajip8549ce32007-05-06 17:53:37 +00006622- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006623 setting a plain string, ie don't expand to single letter identifiers.
6624
Raymond Hettinger13936692007-04-11 18:40:58 +00006625- Request #1191699: Slices can now be pickled.
6626
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006627- Request #1193128: str.translate() now allows a None argument for
6628 translations that only remove characters without re-mapping the
6629 remaining characters.
6630
Georg Brandl5cb76c12007-03-21 09:00:39 +00006631- Patch #1682205: a TypeError while unpacking an iterable is no longer
6632 masked by a generic one with the message "unpack non-sequence".
6633
Neal Norwitzaa754b72007-03-21 06:39:48 +00006634- Remove unused file Python/fmod.c.
6635
Guido van Rossum143b5642007-03-23 04:58:42 +00006636- Bug #1683368: The object.__init__() and object.__new__() methods are
6637 now stricter in rejecting excess arguments. The only time when
6638 either allows excess arguments is when it is not overridden and the
6639 other one is. For backwards compatibility, when both are
6640 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006641 warning later). Also, type.__init__() insists on the same signature
6642 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006643
Georg Brandl3ee81df2008-05-17 18:14:43 +00006644- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6645 object to complex using its __complex__() method before falling back
6646 to the __float__() method. Therefore, the functions in the cmath
6647 module now can operate on objects that define a __complex__()
6648 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006649
Georg Brandl3ee81df2008-05-17 18:14:43 +00006650- Patch #1623563: allow __class__ assignment for classes with
6651 __slots__. The old and the new class are still required to have the
6652 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006653
Georg Brandl3ee81df2008-05-17 18:14:43 +00006654- Patch #1642547: Fix an error/crash when encountering syntax errors
6655 in complex if statements.

6658 ``object.__reduce_ex__()`` is called with an object that is faking
6659 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006660
Georg Brandl3ee81df2008-05-17 18:14:43 +00006661- Patch #1680015: Don't modify __slots__ tuple if it contains an

6665
Georg Brandl7b9c5552007-03-12 14:30:05 +00006666- Bug #1678647: write a newline after printing an exception in any
6667 case, even when converting the value to a string failed.
6668
Georg Brandl871f1bc2007-03-12 13:17:36 +00006669- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006670 its argument, if it exists. If not, it will work like before. This
6671 allows customizing the output of dir() in the presence of a
6672 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006673
Collin Winter276887b2007-03-12 16:11:39 +00006674- Patch #922167: Python no longer segfaults when faced with infinitely
6675 self-recursive reload() calls (as reported by bug #742342).
6676
Georg Brandl3ee81df2008-05-17 18:14:43 +00006677- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00006680- Patch #1491866: change the complex() constructor to allow
6681 parthensized forms. This means complex(repr(x)) now works instead of
6682 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006683
Georg Brandlaa2321b2007-03-07 00:40:28 +00006684- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006685 makes the filenames the warning module prints much more sensible
6686 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006687
Georg Brandl49aafc92007-03-07 00:34:46 +00006688- Variant of patch #697613: don't exit the interpreter on a SystemExit
6689 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006690 variable is given, but break into the interactive interpreter just
6691 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00006698
Georg Brandl0fca97a2007-03-05 22:28:08 +00006699- Patch #1674228: when assigning a slice (old-style), check for the
6700 sq_ass_slice instead of the sq_slice slot.
6701
Georg Brandl3ee81df2008-05-17 18:14:43 +00006702- When printing an unraisable error, don't print exceptions. before
6703 the name. This duplicates the behavior whening normally printing
6704 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00006705
Georg Brandl3ee81df2008-05-17 18:14:43 +00006706- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007206- Added a timeout parameter to the constructor of other protocols
7207 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7208 work started with create_connection() and timeout in httplib, and
7209 closes patch #723312.
7210

7212 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007213 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007214

7235
Georg Brandlf66b6032007-03-14 08:27:52 +00007236- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007237 AttributeError instead of an IOError when the server's response
7238 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007239

Georg Brandl3ee81df2008-05-17 18:14:43 +00007244- Patch #1429539: pdb now correctly initializes the __main__ module
7245 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007246 correctly now.
7247

7254
Georg Brandl3ee81df2008-05-17 18:14:43 +00007255- Patch #1530482: add pydoc.render_doc() which returns the

7265 parameter which can be set to False to prevent the default
7266 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007267
Georg Brandl9e6b4702007-03-13 18:15:41 +00007268- Patch #1581073: add a flag to textwrap that prevents the dropping of
7269 whitespace while wrapping.
7270
Georg Brandl92a6bae2007-03-13 17:43:32 +00007271- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007272 are set for invalid interpolation sequences that would lead to
7273 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007274

Georg Brandl3ee81df2008-05-17 18:14:43 +00007289 field names in its exception message if you try to write a record
7290 with a dictionary containing fields not in the CSV field names list.

7316 returned string up to the first NUL character.
7317

7327
Georg Brandl3ee81df2008-05-17 18:14:43 +00007328- unittest now verifies more of its assumptions. In particular,
7329 TestCase and TestSuite subclasses (not instances) are no longer
7330 accepted in TestSuite.addTest(). This should cause no
7331 incompatibility since it never made sense with ordinary subclasses
7332 -- the failure just occurred later, with a more cumbersome
7333 exception.

7343
Georg Brandl3ee81df2008-05-17 18:14:43 +00007344- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00007722 time so that opening a database previously created with the DB_DUP
7723 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7724 opens. Specifically: dictionary assignment to a DB object will
7725 replace all values for a given key when the database allows
7726 duplicate values. DB users should use DB.put(k, v) when they want
7727 to store duplicates; not DB[k] = v.

7734 characters with ASCII value less than 32. Also, it correctly quotes
7735 dots only if they occur on a single line, as opposed to the previous
7736 behavior of quoting dots if they are the second character of any
7737 line.
