19 effect of appearing to resolve the issue. Thanks to Mark Shannon for
20 noticing.
21

40 longer include a "manifest" to prevent them failing at import time in some
41 embedded situations.

Mark Dickinsondbbed042011-09-19 16:38:08 +010052- Issue #12973: Fix overflow checks that invoked undefined behaviour in
53 int.__pow__. These overflow checks were causing int.__pow__ to produce
54 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010055 compiler optimizing the check away. Also fix similar overflow checks
56 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
57 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010058

69 cleared by the garbage collector. This fixes a segfault when an instance
70 and its type get caught in a reference cycle, and the instance's
71 deallocator calls one of the methods on the type (e.g. when subclassing
72 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinner08563d92011-05-30 23:44:13 +020081 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
82 raw_input() interrupted by CTRL+c.
83
Łukasz Langa7a153902011-10-18 17:16:00 +020084- Issue #10860: httplib now correctly handles an empty port after port
85 delimiter in URLs.

88 name.

Ned Deily87e82bb2011-06-28 19:52:59 -0700357- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
358 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
359 interpreter process. This could cause failures in non-Distutils subprocesses
360 and was unreliable since tests or user programs could modify the interpreter
361 environment after Distutils set it. Instead, have Distutils set the the
362 deployment target only in the environment of each build subprocess. It is
363 still possible to globally override the default by setting
364 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
365 greater or equal to the default value, the value with which the interpreter
366 was built.

396 the ticker doesn't have to wind down to zero from the old starting point
397 before the new interval takes effect. And if the user increases the

1327 This prevents user-created self-referencing ordered dictionaries from
1328 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001790- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1791 start byte and the continuation byte(s) are now considered invalid, instead
1792 of the number of bytes specified by the start byte.
1793 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1794 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1795 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1796 Previous versions returned a single u'\ufffd'.
1797
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001798- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001799 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1800 arises from the "Overriding __eq__ blocks inheritance ..." warning
1801 when turned into an exception: in this case the exception simply
1802 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001803
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001804- Issue #8748: Fix two issues with comparisons between complex and integer
1805 objects. (1) The comparison could incorrectly return True in some cases
1806 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1807 (2) The comparison raised an OverflowError for large integers, leading
1808 to unpredictable exceptions when combining integers and complex objects
1809 in sets or dicts.
1810
Mark Dickinson81336372010-05-30 12:12:25 +00001811- Issue #5211: Implicit coercion for the complex type is now completely
1812 removed. (Coercion for arithmetic operations was already removed in 2.7
1813 alpha 4, but coercion for rich comparisons was accidentally left in.)
1814
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001815- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1816 and error handler, instead of writing to the C stderr file in utf-8
1817
Georg Brandlfee0f442010-05-22 21:26:21 +00001818- Issue #7902: When using explicit relative import syntax, don't try implicit
1819 relative import semantics.

1949 non-float non-integer argument is now converted to an integer (if possible)
1950 using its __int__ method. Previously, only small arguments were treated this
1951 way; larger arguments (those whose __int__ was outside the range of a C long)

2179 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00002191- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2192 with a non-empty format string. This is an effort to future-proof user
2193 code. If a derived class does not currently implement __format__ but later
2194 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002195 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002196 Python 3.3 and it will be an error in Python 3.4.

2247 InvalidOperation instead of returning False. (Comparisons involving a quiet
2248 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

2634 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2635 returning NULL. The macro now returns a statically allocated empty string
2636 instead.

2646 strings,
2647 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2648 numeric strings corresponding to subnormal values,
2649 (3) a memory leak for some values large enough to cause overflow, and
2650 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002681- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002682 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002683 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002688- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002689 file position when calling `truncate()`. It would previously change the file
2690 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002691 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2692

2694 class used to represent files stored inside an archive. The new
2695 implementation is significantly faster and can be wrapped in a
2696 ``io.BufferedReader`` object for more speedups. It also solves an issue
2697 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2698 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002708- Issue #7748: Since unicode values are supported for some metadata options in
2709 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2710 encoded string for them. This ensures that the upload and register commands
2711 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002788- The ``__complex__()`` method is now looked up on the class of instances to
2789 make it consistent with other special methods.

2793
Mark Dickinson1b34d252010-01-01 17:27:30 +00002794- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002795 DeprecationWarning when passed a float argument where an integer was expected.
2796 These functions and methods now raise TypeError instead. The majority of the
2797 effects of this change are in the extension modules, but some core functions
2798 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2799 and many unicode/str methods.

2814 least on IEEE 754 platforms), and in particular does not depend on the
2815 internal representation of a long.

2823
Georg Brandlba83f822010-03-14 09:50:54 +00002824 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002982- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2983 decimal string that's guaranteed to round back to x under correct rounding
2984 (with round-half-to-even rounding mode). Previously it gave a string based on
2985 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2986 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2987 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002989- Issue #7117: On almost all platforms: float-to-string and string-to-float
2990 conversions within Python are now correctly rounded. Places these conversions
2991 occur include: str for floats and complex numbers; the float and complex
2992 constructors; old-style and new-style numeric formatting; serialization and
2993 deserialization of floats and complex numbers using marshal, pickle and json;
2994 parsing of float and imaginary literals in Python code; Decimal-to-float
2995 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002996
Georg Brandlba83f822010-03-14 09:50:54 +00002997 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2998 providing correctly-rounded strtod and dtoa C functions. This code is
2999 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3000 the C compiler. There may be a small number of platforms on which correct
3001 operation of this code cannot be guaranteed, so the code is not used: notably,
3002 this applies to platforms where the C double format is not IEEE 754 binary64,
3003 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3004 and Python's configure script is unable to determine how to change the FPU
3005 precision. On these platforms conversions use the platform strtod and dtoa,
3006 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003008- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3009 uses the correctly-rounded string <-> float conversions described above (when
3010 available), and so produces correctly rounded results that will display nicely
3011 under the float repr. There are two related small changes: (1) round now
3012 accepts any class with an ``__index__()`` method for its second argument (but
3013 no longer accepts floats for the second argument), and (2) an excessively
3014 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3015 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003308- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3309 existing .py counterpart, override the co_filename attributes of all code

3365
Georg Brandlba83f822010-03-14 09:50:54 +00003366- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3367 file objects with closefd=False. The file descriptor is still kept open but
3368 the file object behaves like a closed file. The ``FileIO`` object also got a

3394 this code path is really executed because I cannot move to such directory on
3395 win2k)

3421 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Antoine Pitrou0668c622008-08-26 22:42:08 +00004824 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4825 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4826 when given a tuple of classes as second argument, were looking up
4827 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4828 type object.
4829

Brett Cannon1eaf0742008-09-02 01:25:16 +00004899 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4900 for catch_warnings() also led to an improvement in the raising of a
4901 DeprecationWarning related to warnings.warn_explicit().
4902

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004926- Issue #2975: When compiling several extension modules with Visual Studio 2008
4927 from the same python interpreter, some environment variables would grow
4928 without limit.
4929
Benjamin Peterson37346b22008-08-23 20:27:43 +00004930- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004967What's New in Python 2.6 beta 3?
4968================================
4969
Barry Warsaw07a4a382008-08-21 01:15:08 +00004970*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004971
4972Core and Builtins
4973-----------------
4974
Guido van Rossumf8402962008-08-20 15:01:50 +00004975- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4976 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4977 extensions do not automatically benefit from the class attribute
4978 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4979 to their tp_flags field if they care. This is a backwards
4980 compatibility feature; in 3.0, all types will use the cache by
4981 default.
4982
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004983- Keyword arguments can now follow starred arguments. (``f(a, *args,
4984 keyword=23)`` is now valid syntax.)
4985
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004986- ctypes function pointers that are COM methods have a boolean True
4987 value again.
4988
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004989- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4990 by denying s# to parse objects that have a releasebuffer procedure,
4991 and introducing s*.
4992
Georg Brandl1e13ea92008-08-11 09:07:59 +00004993- Issue #3537: Fix an assertion failure when an empty but presized dict
4994 object was stored in the freelist.
4995
Mark Dickinsonb6467572008-08-04 21:30:09 +00004996- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4997 ValueError consistently across platforms.
4998
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004999- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5000 (64bit Unix, for example), unichr() would truncate its argument and return
5001 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5002
Neal Norwitze7d8be82008-07-31 17:17:14 +00005003- Apply security patches from Apple.
5004
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005005- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5006 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5007
Antoine Pitrou92f82162008-07-25 22:22:08 +00005008- Issue #1819: function calls with several named parameters are now on
5009 average 35% faster (as measured by pybench).
5010
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005011- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5012 the python debugger steps into a class statement: the free variables (local
5013 variables defined in an outer scope) would be deleted from the outer scope.
5014
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005015- Issue #2620: Overflow checking when allocating or reallocating memory
5016 was not always being done properly in some python types and extension
5017 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5018 all been updated to perform better checks and places in the code that
5019 would previously leak memory on the error path when such an allocation
5020 failed have been fixed.

5023-------
5024
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005025- Issue #3612: Added some missing basic types in ctypes.wintypes.
5026
Benjamin Petersone977ad42008-08-20 01:42:01 +00005027- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5028 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5029
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005030- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5031 version reported by these tools does not necessarily follow the python
5032 version numbering scheme, so the module is less strict when parsing it.
5033
Nick Coghlanf70385a2008-08-18 12:42:46 +00005034- Issue #2235: Added Py3k warnings for types which will become unhashable
5035 under the stricter __hash__ inheritance rules in 3.0. Several types
5036 which did not meet the rules for hash invariants and were already
5037 unhashable in 3.0 have now been explicitly flagged as unhashable in
5038 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5039 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5040
Brett Cannon88f801d2008-08-18 00:46:22 +00005041- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5042 imported into the module but exposed as part of the module's API.
5043
Brett Cannon7b96f072008-08-18 00:41:11 +00005044- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5045
Brett Cannon46225e72008-08-18 00:36:52 +00005046- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005048- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5049
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005050- Issue #3575: Incremental decoder's decode function now takes bytearray
5051 by using 's*' instead of 't#'.
5052
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005053- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005054 fails unicode conversion on 2nd parameter. (windows only)
5055
Georg Brandl222e2082010-08-01 22:27:39 +00005056- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005057 in a redirect.
5058
Brett Cannonabe423e2008-08-16 21:47:07 +00005059- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005060 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005061
Facundo Batistaeb90b782008-08-16 14:44:07 +00005062- Issue #2776: fixed small issue when handling an URL with double slash
5063 after a 302 response in the case of not going through a proxy.
5064
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005065- Issue #2676: in the email package, content-type parsing was hanging on
5066 pathological input because of quadratic or exponential behaviour of a
5067 regular expression.
5068
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005069- Issue #3476: binary buffered reading through the new "io" library is now
5070 thread-safe.
5071
Brett Cannonbf3157b2008-08-14 05:00:03 +00005072- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5073 since mimetools itself is deprecated. Because modules are cached, all
5074 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5075
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005076- Issue #3134: shutil referenced undefined WindowsError symbol.
5077
Robert Schuppenies14646332008-08-10 11:01:53 +00005078- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5079 menu entries were not deleted.
5080
Brett Cannon83e81842008-08-09 23:30:55 +00005081- Copied the implementation of reduce() to _functools.reduce() to have a
5082 version that did not raise a DeprecationWarning under -3.
5083
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005084- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5085 a MemoryError rather than silently stop the iteration.
5086
Guido van Rossum59ce9012008-08-09 14:55:34 +00005087- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5088 to _sre.compile() will now be rejected. This should not affect anybody
5089 since the re.compile() function never generates invalid re-bytecode.
5090
Skip Montanaroa032bf42008-08-08 22:52:51 +00005091- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5092 upon first access it can be automatically initialized from the csv file if
5093 it wasn't initialized during instantiation.
5094
Brett Cannon3aa2a492008-08-06 22:28:09 +00005095- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5096 the reload() built-in has been removed.
5097
Brett Cannon7e30b672008-08-04 21:52:25 +00005098- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005099 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5102 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5103 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5104 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005105

5167-----------------
5168
Georg Brandl3e483f62008-07-16 22:57:41 +00005169- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5170 its methods now allow for items objects that can be converted to
5171 an integer using operator.index().
5172
Mark Dickinson64b7e502008-07-16 09:40:03 +00005173- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5174 produced a ValueError instead of giving the correct float.
5175
Eric Smitha5fa5a22008-07-16 00:11:49 +00005176- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5177 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5178
Mark Dickinson7103aa42008-07-15 19:08:33 +00005179- Issue #3008: the float type has a new instance method 'float.hex'
5180 and a new class method 'float.fromhex' to convert floating-point
5181 numbers to and from hexadecimal strings, respectively.
5182
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005183- Issue #2235: __hash__ is once again inherited by default. To allow
5184 collections.Hashable to remain meaningful in the presence of the
5185 default hash implementation (object.__hash__), it is now possible
5186 to explicit block inheritance of hash by setting __hash__=None at
5187 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5188 level.
5189
Nick Coghlanb028f502008-07-13 14:52:36 +00005190- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5191 the parent module cannot be found while performing an absolute import.
5192 This means that an incorrectly defined __package__ attribute will
5193 now only prevent relative imports in that module rather than causing
5194 all imports from that module to fail.
5195
Nick Coghlan14ff9942008-07-08 14:21:42 +00005196- Issue #2517: Allow unicode messages in Exceptions again by correctly

5206 another thread's dictionary.
5207
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005208- Issue #3004: Minor change to slice.indices(): the start and stop
5209 arguments are now treated identically, making the behaviour easier
5210 to describe and understand. For example, slice(None, -10,
5211 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5212 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5213 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00005215- Issue #3219: Calling a function with repeated keyword arguments,
5216 f(a=2, a=23), would not cause a syntax error. This was a regression
5217 from 2.4 caused by the switch to the new compiler.

5256 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005257 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005258 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005274- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl74a1dea2008-05-28 11:21:39 +00005685- Add ``PyType_Modified()`` as a public API to clear the type cache.
5686
5687- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00005688
5689- The PyString functions have been renamed to PyBytes. A batch of
5690 defines were added so that the linker still sees the original
5691 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005729- Issue #1631171: Re-implement the 'warnings' module in C (the
5730 original Python code has been kept as backup). This will allow for
5731 using the 'warning's machinery in such places as the parser where
5732 use of pure Python code is not possible. Both the ``showarning()``
5733 and ``formatwarning()`` gain an optional 'line' argument which is
5734 not called by default for backwards-compatibility reasons. Setting
5735 ``warnings.showwarning()`` to an implementation that lacks support
5736 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005761- The getpass module has been improved on Unix. It now uses /dev/tty
5762 by default and uses stderr instead of stdout. A GetPassWarning is
5763 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005778- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005779 extension modules between 32 and 64 bit platforms. See the distutls

5783 threads at once without fear of crashing the Python interpreter. If
5784 file.close() is called while an object is in use by another thread
5785 an IOError exception will be raised and the file will not be closed.
5786
Thomas Hellerf7906482008-04-04 19:43:25 +00005787- The bundled libffi copy is now in sync with the recently released

5792 so the controlled environment will more closely mirror the typical
5793 script environment. This supports setup.py scripts that refer to
5794 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005799- Issue #2550: The approach used by client/server code for obtaining
5800 ports to listen on in network-oriented tests has been refined in an
5801 effort to facilitate running multiple instances of the entire
5802 regression test suite in parallel without issue.
5803 test_support.bind_port() has been fixed such that it will always
5804 return a unique port -- which wasn't always the case with the
5805 previous implementation, especially if socket options had been set
5806 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5807 new implementation of bind_port() will actually raise an exception
5808 if it is passed an AF_INET/SOCK_STREAM socket with either the
5809 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5810 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5811 the socket it's been passed. This currently only applies to
5812 Windows. This option prevents any other sockets from binding to the
5813 host/port we've bound to, thus removing the possibility of the
5814 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5815 when a second SOCK_STREAM socket binds and accepts to a host/port
5816 that's already been bound by another socket. The optional preferred
5817 port parameter to bind_port() has been removed. Under no
5818 circumstances should tests be hard coding ports!
5819
5820 test_support.find_unused_port() has also been introduced, which will
5821 pass a temporary socket object to bind_port() in order to obtain an
5822 unused port. The temporary socket object is then closed and
5823 deleted, and the port is returned. This method should only be used
5824 for obtaining an unused port in order to pass to an external program
5825 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5826 a parameter to a server-oriented class that doesn't give you direct
5827 access to the underlying socket used.
5828
5829 Finally, test_support.HOST has been introduced, which should be used
5830 for the host argument of any relevant socket calls (i.e. bind and
5831 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005832
5833 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005834 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005835 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5836 test_asynchat and test_socket_ssl.
5837
Georg Brandl3ee81df2008-05-17 18:14:43 +00005838 It is now possible for multiple instances of the regression test
5839 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006118- Added the future_builtins module, which contains hex() and oct().
6119 These are the PEP 3127 version of these functions, designed to be
6120 compatible with the hex() and oct() builtins from Python 3.0. They
6121 differ slightly in their output formats from the existing, unchanged
6122 Python 2.6 builtins. The expected usage of the future_builtins
6123 module is:
6124 from future_builtins import hex, oct
6125
Eric Smith7ef40bf2008-02-20 23:34:22 +00006126- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6127 exponents for exponents with absolute value < 100. Follows C99
6128 standard. This is a change on Windows, which would use 3 digits.
6129 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6130 so that any alterations it does to the resulting string will be
6131 available in stringlib/formatter.h (for float.__format__).
6132
Eric Smith5a3c1352008-02-19 13:21:56 +00006133- Implemented PEP 3101, Advanced String Formatting. This adds a new
6134 builtin format(); a format() method for str and unicode; a
6135 __format__() method to object, str, unicode, int, long, float, and
6136 datetime; the class string.Formatter; and the C API
6137 PyObject_Format().
6138
Georg Brandl3ee81df2008-05-17 18:14:43 +00006139- Fixed several potential crashes, all caused by specially crafted
6140 __del__ methods exploiting objects in temporarily inconsistent
6141 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006142
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006143- Issue #2115: Important speedup in setting __slot__ attributes. Also

6152 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006153
Georg Brandl3ee81df2008-05-17 18:14:43 +00006154- Issue #2045: Fix an infinite recursion triggered when printing a
6155 subclass of collections.defaultdict, if its default_factory is set
6156 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006157
Christian Heimesf75dbef2008-02-08 00:11:31 +00006158- Fixed a minor memory leak in dictobject.c. The content of the free

6167
Georg Brandl3ee81df2008-05-17 18:14:43 +00006168- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6169 calls. Python expected the return type int but the fork familie
6170 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006171

Georg Brandl3ee81df2008-05-17 18:14:43 +00006184- Patch #1473257: generator objects gain a gi_code attribute. This is
6185 the same object as the func_code attribute of the function that
6186 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006187
Georg Brandl3ee81df2008-05-17 18:14:43 +00006188- Issue #1920: "while 0" statements were completely removed by the
6189 compiler, even in the presence of an "else" clause, which is

6191 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00006193- A few crashers fixed: weakref_in_del.py (issue #1377858);
6194 loosing_dict_ref.py (issue #1303614, test67.py);
6195 borrowed_ref_[34].py (not in tracker).
6196
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006197- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006198 suppressed while an extension is loaded by calling SetErrorMode in
6199 dynload_win.c. The error is still reported properly.
6200
Georg Brandl3ee81df2008-05-17 18:14:43 +00006201- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006202 several extension methods and modules do not work without unicode
6203 support.
6204
Georg Brandl26543b12008-01-21 18:36:51 +00006205- Issue #1882: when compiling code from a string, encoding cookies in the
6206 second line of code were not always recognized correctly.
6207
Georg Brandl14404b62008-01-19 19:27:05 +00006208- Issue #1679: "0x" was taken as a valid integer literal.
6209
Georg Brandl6caad7d2008-01-26 14:19:22 +00006210- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006211 added.
6212
Christian Heimesc94e2b52008-01-14 04:13:37 +00006213- sys.float_info / PyFloat_GetInfo: The floating point information
6214 object was converted from a dict to a specialized structseq object.
6215
Georg Brandl3ee81df2008-05-17 18:14:43 +00006216- Patch #1816: Added sys.flags structseq. It exposes the status of
6217 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006218
Georg Brandl3ee81df2008-05-17 18:14:43 +00006219- Objects/structseq.c: Implemented new structseq representation. The
6220 patch makes structseqs (e.g. the return value of os.stat) more
6221 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006222
Georg Brandl3ee81df2008-05-17 18:14:43 +00006223- Patch #1700288: added a type attribute cache that caches method
6224 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006225
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006226- Bug #1776: __import__() no longer accepts filenames on any platform.
6227 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006228
Georg Brandlaed6c662008-01-07 17:25:53 +00006229- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6230
Georg Brandl3ee81df2008-05-17 18:14:43 +00006231- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6232 envvar and sys.dont_write_bytecode attribute. All these can be set
6233 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006234
Georg Brandl3ee81df2008-05-17 18:14:43 +00006235- Improve some exception messages when Windows fails to load an
6236 extension module. Now we get for example '%1 is not a valid Win32
6237 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006238
Georg Brandl3ee81df2008-05-17 18:14:43 +00006239- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006241- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6242 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006243
Christian Heimes0a8143f2007-12-18 23:22:54 +00006244- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006245 and INF. float("nan"), float("inf") and float("-inf") now work on
6246 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006247
Georg Brandl3ee81df2008-05-17 18:14:43 +00006248- Compiler now generates simpler and faster code for dictionary
6249 literals. The oparg for BUILD_MAP now indicates an estimated
6250 dictionary size. There is a new opcode, STORE_MAP, for adding
6251 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006280- Patch #1739468: Directories and zipfiles containing a __main__.py
6281 file can now be directly executed by passing their name to the
6282 interpreter. The directory/zipfile is automatically inserted as the
6283 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006284
Georg Brandl3ee81df2008-05-17 18:14:43 +00006285- Issue #1265: Fix a problem with sys.settrace, if the tracing
6286 function uses a generator expression when at the same time the
6287 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006288
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006289- sets and frozensets now have an isdisjoint() method.
6290
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006291- optimize the performance of builtin.sum().
6292
Neal Norwitz44f326e2007-10-05 05:29:17 +00006293- Fix warnings found by the new version of the Coverity checker.
6294
Georg Brandl21e99f42010-03-07 15:23:59 +00006295- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006296 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6297 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006298
Georg Brandl3ee81df2008-05-17 18:14:43 +00006299- Issue #1686386: Tuple's tp_repr did not take into account the
6300 possibility of having a self-referential tuple, which is possible
6301 from C code. Nor did object's tp_str consider that a type's tp_str
6302 could do something that could lead to an inifinite recursion.
6303 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6304 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006305
Georg Brandl3ee81df2008-05-17 18:14:43 +00006306- Issue #1164: It was possible to trigger deadlock when using the
6307 'print' statement to write to a file since the GIL was not released
6308 as needed. Now PyObject_Print() does the right thing along with
6309 various tp_print implementations of the built-in types and those in
6310 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006311
Georg Brandl3ee81df2008-05-17 18:14:43 +00006312- Issue #1147: Exceptions were directly allowing string exceptions in
6313 their throw() method even though string exceptions no longer
6314 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006315
Georg Brandl3ee81df2008-05-17 18:14:43 +00006316- Issue #1096: Prevent a segfault from getting the repr of a very
6317 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006318
Brett Cannon1e534b52007-09-07 04:18:30 +00006319- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006320 PyObject_Call() never calling back out to Python code to trigger
6321 recursion depth updates/checks. Required the creation of a static
6322 RuntimeError instance in case normalizing an exception put the
6323 recursion check value past its limit. Fixes crashers
6324 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006325
Georg Brandl3ee81df2008-05-17 18:14:43 +00006326- Patch #1031213: Decode source line in SyntaxErrors back to its

6330 with %G.
6331
Georg Brandl3ee81df2008-05-17 18:14:43 +00006332- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00006339- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006340 __*__ attributes. (Some already existed, e.g., __doc__ and
6341 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006342
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006343- Add -3 option to the interpreter to warn about features that are
6344 deprecated and will be changed/removed in Python 3.0.
6345
Georg Brandl2134e752007-05-21 20:34:16 +00006346- Patch #1686487: you can now pass any mapping after '**' in function
6347 calls.
6348
Collin Winter62903052007-05-18 23:11:24 +00006349- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006350 "except E as target:". This is to provide forwards compatibility
6351 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006352
Brett Cannon229cee22007-05-05 01:34:02 +00006353- Deprecate BaseException.message as per PEP 352.
6354
Georg Brandl3ee81df2008-05-17 18:14:43 +00006355- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006356 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006357
Vinay Sajip8549ce32007-05-06 17:53:37 +00006358- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006359 setting a plain string, ie don't expand to single letter identifiers.
6360
Raymond Hettinger13936692007-04-11 18:40:58 +00006361- Request #1191699: Slices can now be pickled.
6362
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006363- Request #1193128: str.translate() now allows a None argument for
6364 translations that only remove characters without re-mapping the
6365 remaining characters.
6366
Georg Brandl5cb76c12007-03-21 09:00:39 +00006367- Patch #1682205: a TypeError while unpacking an iterable is no longer
6368 masked by a generic one with the message "unpack non-sequence".
6369
Neal Norwitzaa754b72007-03-21 06:39:48 +00006370- Remove unused file Python/fmod.c.
6371
Guido van Rossum143b5642007-03-23 04:58:42 +00006372- Bug #1683368: The object.__init__() and object.__new__() methods are
6373 now stricter in rejecting excess arguments. The only time when
6374 either allows excess arguments is when it is not overridden and the
6375 other one is. For backwards compatibility, when both are
6376 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006377 warning later). Also, type.__init__() insists on the same signature
6378 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006379
Georg Brandl3ee81df2008-05-17 18:14:43 +00006380- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6381 object to complex using its __complex__() method before falling back
6382 to the __float__() method. Therefore, the functions in the cmath
6383 module now can operate on objects that define a __complex__()
6384 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006385
Georg Brandl3ee81df2008-05-17 18:14:43 +00006386- Patch #1623563: allow __class__ assignment for classes with
6387 __slots__. The old and the new class are still required to have the
6388 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006389
Georg Brandl3ee81df2008-05-17 18:14:43 +00006390- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00006393- Patch #1462488: Python no longer segfaults when
6394 ``object.__reduce_ex__()`` is called with an object that is faking
6395 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006396
Georg Brandl3ee81df2008-05-17 18:14:43 +00006397- Patch #1680015: Don't modify __slots__ tuple if it contains an

6401
Georg Brandl7b9c5552007-03-12 14:30:05 +00006402- Bug #1678647: write a newline after printing an exception in any
6403 case, even when converting the value to a string failed.
6404
Georg Brandl871f1bc2007-03-12 13:17:36 +00006405- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006406 its argument, if it exists. If not, it will work like before. This
6407 allows customizing the output of dir() in the presence of a
6408 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00006410- Patch #922167: Python no longer segfaults when faced with infinitely
6411 self-recursive reload() calls (as reported by bug #742342).
6412
Georg Brandl3ee81df2008-05-17 18:14:43 +00006413- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00006416- Patch #1491866: change the complex() constructor to allow
6417 parthensized forms. This means complex(repr(x)) now works instead of
6418 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006419
Georg Brandlaa2321b2007-03-07 00:40:28 +00006420- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006421 makes the filenames the warning module prints much more sensible
6422 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006423
Georg Brandl49aafc92007-03-07 00:34:46 +00006424- Variant of patch #697613: don't exit the interpreter on a SystemExit
6425 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006426 variable is given, but break into the interactive interpreter just
6427 like on other exceptions or normal program exit.

6930
Facundo Batistad918a652007-04-24 13:54:38 +00006931- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006932 the client's request was successfully received, understood, and
6933 accepted. Now in these cases no error is raised in urllib (issue
6934 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006942- Added a timeout parameter to the constructor of other protocols
6943 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6944 work started with create_connection() and timeout in httplib, and
6945 closes patch #723312.
6946
Vinay Sajip8549ce32007-05-06 17:53:37 +00006947- Patch #1676823: Added create_connection() to socket.py, which may be
6948 called with a timeout, and use it from httplib (whose HTTPConnection

6971
Georg Brandlf66b6032007-03-14 08:27:52 +00006972- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006973 AttributeError instead of an IOError when the server's response
6974 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006975
Georg Brandl3ee81df2008-05-17 18:14:43 +00006976- Patch #957650: "%var%" environment variable references are now
6977 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00006980- Patch #1429539: pdb now correctly initializes the __main__ module
6981 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006982 correctly now.
6983

6990
Georg Brandl3ee81df2008-05-17 18:14:43 +00006991- Patch #1530482: add pydoc.render_doc() which returns the
6992 documentation for a thing instead of paging it to stdout, which
6993 pydoc.doc() does.

Georg Brandl9e6b4702007-03-13 18:15:41 +00007004- Patch #1581073: add a flag to textwrap that prevents the dropping of
7005 whitespace while wrapping.
7006
Georg Brandl92a6bae2007-03-13 17:43:32 +00007007- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007008 are set for invalid interpolation sequences that would lead to
7009 errors on reading back those values.

7052 returned string up to the first NUL character.

7063
Georg Brandl3ee81df2008-05-17 18:14:43 +00007064- unittest now verifies more of its assumptions. In particular,
7065 TestCase and TestSuite subclasses (not instances) are no longer
7066 accepted in TestSuite.addTest(). This should cause no
7067 incompatibility since it never made sense with ordinary subclasses
7068 -- the failure just occurred later, with a more cumbersome
7069 exception.

7078 given a unicode argument and os.listdir() returns unicode filenames.
7079
Georg Brandl3ee81df2008-05-17 18:14:43 +00007080- Patch #1673619: setup.py identifies extension modules it doesn't

7082 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007458 time so that opening a database previously created with the DB_DUP
7459 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7460 opens. Specifically: dictionary assignment to a DB object will
7461 replace all values for a given key when the database allows
7462 duplicate values. DB users should use DB.put(k, v) when they want
7463 to store duplicates; not DB[k] = v.

7470 characters with ASCII value less than 32. Also, it correctly quotes
7471 dots only if they occur on a single line, as opposed to the previous
7472 behavior of quoting dots if they are the second character of any
7473 line.
