796 32-bit-only installer Pythons on systems with Xcode 4 (currently
797 OS X 10.8, 10.7, and optionally 10.6).
798 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
799 * Since Xcode 4 removes ppc support, extension module builds now
800 check for ppc compiler support and by default remove ppc and
801 ppc64 archs when they are not available.
802 * Extension module builds now revert to using system installed
803 headers and libs (/usr and /System/Library) if the SDK used
804 to build the interpreter is not installed or has moved.
805 * Try to avoid building extension modules with deprecated
806 and problematic Apple llvm-gcc compiler. If original compiler
807 is not available, use clang instead by default.

1156 64-bit/32-bit Pythons. If the user does not explicitly override
1157 the default C compiler by setting the CC environment variable,
1158 Distutils will now attempt to compile extension modules with clang
1159 if gcc-4.2 is required but not found. Also as a convenience, if
1160 the user does explicitly set CC, substitute its value as the default
1161 compiler in the Distutils LDSHARED configuration variable for OS X.

1163 SDK, neither of which are available in Xcode 4. This change does not
1164 attempt to override settings to support their use with Xcode 4.)

1440 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001441 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001442 deployment target only in the environment of each build subprocess. It is
1443 still possible to globally override the default by setting
1444 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1445 greater or equal to the default value, the value with which the interpreter
1446 was built.

1476 the ticker doesn't have to wind down to zero from the old starting point
1477 before the new interval takes effect. And if the user increases the
1478 interval, it makes sure the new limit takes effect right away rather have an
1479 early task switch before recognizing the new interval.

2431 This prevents user-created self-referencing ordered dictionaries from
2432 becoming permanently uncollectable GC garbage. The downside is that

2434 GC collection rather than freeing memory immediately when the refcnt drops
2435 to zero.

2893
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002894- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2895 start byte and the continuation byte(s) are now considered invalid, instead
2896 of the number of bytes specified by the start byte.
2897 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2898 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2899 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2900 Previous versions returned a single u'\ufffd'.
2901
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002902- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002903 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2904 arises from the "Overriding __eq__ blocks inheritance ..." warning
2905 when turned into an exception: in this case the exception simply
2906 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002907
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002908- Issue #8748: Fix two issues with comparisons between complex and integer
2909 objects. (1) The comparison could incorrectly return True in some cases
2910 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2911 (2) The comparison raised an OverflowError for large integers, leading
2912 to unpredictable exceptions when combining integers and complex objects
2913 in sets or dicts.
2914
Mark Dickinson81336372010-05-30 12:12:25 +00002915- Issue #5211: Implicit coercion for the complex type is now completely
2916 removed. (Coercion for arithmetic operations was already removed in 2.7
2917 alpha 4, but coercion for rich comparisons was accidentally left in.)
2918
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002919- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2920 and error handler, instead of writing to the C stderr file in utf-8
2921
Georg Brandlfee0f442010-05-22 21:26:21 +00002922- Issue #7902: When using explicit relative import syntax, don't try implicit
2923 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00002924
Georg Brandlfee0f442010-05-22 21:26:21 +00002925- Issue #7079: Fix a possible crash when closing a file object while using it
2926 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +00002927
Victor Stinnerb65bd2e2010-06-11 19:22:28 +00002928- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00002929 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +00002934- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
2935 of the interpreter to set sys.argv without also modifying sys.path. This
2936 helps fix `CVE-2008-5983

3053 non-float non-integer argument is now converted to an integer (if possible)
3054 using its __int__ method. Previously, only small arguments were treated this
3055 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00003295- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3296 with a non-empty format string. This is an effort to future-proof user
3297 code. If a derived class does not currently implement __format__ but later
3298 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003299 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003300 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00003737- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3738 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3739 returning NULL. The macro now returns a statically allocated empty string
3740 instead.

3750 strings,
3751 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3752 numeric strings corresponding to subnormal values,
3753 (3) a memory leak for some values large enough to cause overflow, and
3754 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00003785- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003786 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003787 Also, raise ValueError rather than TypeError when an unknown TIPC address
3788 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003792- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003793 file position when calling `truncate()`. It would previously change the file
3794 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003795 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3796

3798 class used to represent files stored inside an archive. The new
3799 implementation is significantly faster and can be wrapped in a
3800 ``io.BufferedReader`` object for more speedups. It also solves an issue
3801 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3802 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003812- Issue #7748: Since unicode values are supported for some metadata options in
3813 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3814 encoded string for them. This ensures that the upload and register commands
3815 send the correct values to PyPI without any error.

3900 These functions and methods now raise TypeError instead. The majority of the
3901 effects of this change are in the extension modules, but some core functions
3902 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3903 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004086- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4087 decimal string that's guaranteed to round back to x under correct rounding
4088 (with round-half-to-even rounding mode). Previously it gave a string based on
4089 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4090 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4091 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004093- Issue #7117: On almost all platforms: float-to-string and string-to-float
4094 conversions within Python are now correctly rounded. Places these conversions
4095 occur include: str for floats and complex numbers; the float and complex
4096 constructors; old-style and new-style numeric formatting; serialization and
4097 deserialization of floats and complex numbers using marshal, pickle and json;
4098 parsing of float and imaginary literals in Python code; Decimal-to-float
4099 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004100
Georg Brandlba83f822010-03-14 09:50:54 +00004101 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4102 providing correctly-rounded strtod and dtoa C functions. This code is
4103 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4104 the C compiler. There may be a small number of platforms on which correct
4105 operation of this code cannot be guaranteed, so the code is not used: notably,
4106 this applies to platforms where the C double format is not IEEE 754 binary64,
4107 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4108 and Python's configure script is unable to determine how to change the FPU
4109 precision. On these platforms conversions use the platform strtod and dtoa,
4110 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004112- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4113 uses the correctly-rounded string <-> float conversions described above (when
4114 available), and so produces correctly rounded results that will display nicely
4115 under the float repr. There are two related small changes: (1) round now
4116 accepts any class with an ``__index__()`` method for its second argument (but
4117 no longer accepts floats for the second argument), and (2) an excessively
4118 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4119 raises an exception.

Antoine Pitrou0668c622008-08-26 22:42:08 +00005928 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5929 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5930 when given a tuple of classes as second argument, were looking up
5931 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5932 type object.
5933

5943 function 'stringlib_contains_obj'.
5944
Benjamin Peterson712ee922008-08-24 18:10:20 +00005945- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00006003 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6004 for catch_warnings() also led to an improvement in the raising of a
6005 DeprecationWarning related to warnings.warn_explicit().
6006

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006030- Issue #2975: When compiling several extension modules with Visual Studio 2008
6031 from the same python interpreter, some environment variables would grow
6032 without limit.
6033
Benjamin Peterson37346b22008-08-23 20:27:43 +00006034- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006071What's New in Python 2.6 beta 3?
6072================================
6073
Barry Warsaw07a4a382008-08-21 01:15:08 +00006074*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006075
6076Core and Builtins
6077-----------------
6078
Guido van Rossumf8402962008-08-20 15:01:50 +00006079- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6080 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6081 extensions do not automatically benefit from the class attribute
6082 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6083 to their tp_flags field if they care. This is a backwards
6084 compatibility feature; in 3.0, all types will use the cache by
6085 default.
6086
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006087- Keyword arguments can now follow starred arguments. (``f(a, *args,
6088 keyword=23)`` is now valid syntax.)
6089
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006090- ctypes function pointers that are COM methods have a boolean True
6091 value again.
6092
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006093- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6094 by denying s# to parse objects that have a releasebuffer procedure,
6095 and introducing s*.
6096
Georg Brandl1e13ea92008-08-11 09:07:59 +00006097- Issue #3537: Fix an assertion failure when an empty but presized dict
6098 object was stored in the freelist.
6099
Mark Dickinsonb6467572008-08-04 21:30:09 +00006100- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6101 ValueError consistently across platforms.
6102
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006103- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6104 (64bit Unix, for example), unichr() would truncate its argument and return
6105 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6106
Neal Norwitze7d8be82008-07-31 17:17:14 +00006107- Apply security patches from Apple.
6108
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006109- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6110 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6111
Antoine Pitrou92f82162008-07-25 22:22:08 +00006112- Issue #1819: function calls with several named parameters are now on
6113 average 35% faster (as measured by pybench).
6114
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006115- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6116 the python debugger steps into a class statement: the free variables (local
6117 variables defined in an outer scope) would be deleted from the outer scope.
6118
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006119- Issue #2620: Overflow checking when allocating or reallocating memory
6120 was not always being done properly in some python types and extension
6121 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6122 all been updated to perform better checks and places in the code that
6123 would previously leak memory on the error path when such an allocation
6124 failed have been fixed.

6127-------
6128
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006129- Issue #3612: Added some missing basic types in ctypes.wintypes.
6130
Benjamin Petersone977ad42008-08-20 01:42:01 +00006131- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6132 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6133
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006134- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6135 version reported by these tools does not necessarily follow the python
6136 version numbering scheme, so the module is less strict when parsing it.
6137
Nick Coghlanf70385a2008-08-18 12:42:46 +00006138- Issue #2235: Added Py3k warnings for types which will become unhashable
6139 under the stricter __hash__ inheritance rules in 3.0. Several types
6140 which did not meet the rules for hash invariants and were already
6141 unhashable in 3.0 have now been explicitly flagged as unhashable in
6142 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6143 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6144
Brett Cannon88f801d2008-08-18 00:46:22 +00006145- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6146 imported into the module but exposed as part of the module's API.
6147
Brett Cannon7b96f072008-08-18 00:41:11 +00006148- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6149
Brett Cannon46225e72008-08-18 00:36:52 +00006150- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006152- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6153
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006154- Issue #3575: Incremental decoder's decode function now takes bytearray
6155 by using 's*' instead of 't#'.
6156
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006157- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006158 fails unicode conversion on 2nd parameter. (windows only)
6159
Georg Brandl222e2082010-08-01 22:27:39 +00006160- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006161 in a redirect.
6162
Brett Cannonabe423e2008-08-16 21:47:07 +00006163- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006164 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006165
Facundo Batistaeb90b782008-08-16 14:44:07 +00006166- Issue #2776: fixed small issue when handling an URL with double slash
6167 after a 302 response in the case of not going through a proxy.
6168
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006169- Issue #2676: in the email package, content-type parsing was hanging on
6170 pathological input because of quadratic or exponential behaviour of a
6171 regular expression.
6172
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006173- Issue #3476: binary buffered reading through the new "io" library is now
6174 thread-safe.
6175
Brett Cannonbf3157b2008-08-14 05:00:03 +00006176- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6177 since mimetools itself is deprecated. Because modules are cached, all
6178 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6179
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006180- Issue #3134: shutil referenced undefined WindowsError symbol.
6181
Robert Schuppenies14646332008-08-10 11:01:53 +00006182- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6183 menu entries were not deleted.
6184
Brett Cannon83e81842008-08-09 23:30:55 +00006185- Copied the implementation of reduce() to _functools.reduce() to have a
6186 version that did not raise a DeprecationWarning under -3.
6187
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006188- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6189 a MemoryError rather than silently stop the iteration.
6190
Guido van Rossum59ce9012008-08-09 14:55:34 +00006191- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6192 to _sre.compile() will now be rejected. This should not affect anybody
6193 since the re.compile() function never generates invalid re-bytecode.
6194
Skip Montanaroa032bf42008-08-08 22:52:51 +00006195- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6196 upon first access it can be automatically initialized from the csv file if
6197 it wasn't initialized during instantiation.
6198
Brett Cannon3aa2a492008-08-06 22:28:09 +00006199- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6200 the reload() built-in has been removed.
6201
Brett Cannon7e30b672008-08-04 21:52:25 +00006202- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006203 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6206 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6207 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6208 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006209

6271-----------------
6272
Georg Brandl3e483f62008-07-16 22:57:41 +00006273- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6274 its methods now allow for items objects that can be converted to
6275 an integer using operator.index().
6276
Mark Dickinson64b7e502008-07-16 09:40:03 +00006277- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6278 produced a ValueError instead of giving the correct float.
6279
Eric Smitha5fa5a22008-07-16 00:11:49 +00006280- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6281 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6282
Mark Dickinson7103aa42008-07-15 19:08:33 +00006283- Issue #3008: the float type has a new instance method 'float.hex'
6284 and a new class method 'float.fromhex' to convert floating-point
6285 numbers to and from hexadecimal strings, respectively.
6286
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006287- Issue #2235: __hash__ is once again inherited by default. To allow
6288 collections.Hashable to remain meaningful in the presence of the
6289 default hash implementation (object.__hash__), it is now possible
6290 to explicit block inheritance of hash by setting __hash__=None at
6291 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6292 level.
6293
Nick Coghlanb028f502008-07-13 14:52:36 +00006294- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6295 the parent module cannot be found while performing an absolute import.
6296 This means that an incorrectly defined __package__ attribute will
6297 now only prevent relative imports in that module rather than causing
6298 all imports from that module to fail.
6299
Nick Coghlan14ff9942008-07-08 14:21:42 +00006300- Issue #2517: Allow unicode messages in Exceptions again by correctly

6310 another thread's dictionary.
6311
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006312- Issue #3004: Minor change to slice.indices(): the start and stop
6313 arguments are now treated identically, making the behaviour easier
6314 to describe and understand. For example, slice(None, -10,
6315 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6316 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6317 10, -1).
6318
Georg Brandl278fc502008-07-19 12:46:12 +00006319- Issue #3219: Calling a function with repeated keyword arguments,
6320 f(a=2, a=23), would not cause a syntax error. This was a regression
6321 from 2.4 caused by the switch to the new compiler.

6360 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006361 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006362 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006378- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6788
Georg Brandl74a1dea2008-05-28 11:21:39 +00006789- Add ``PyType_Modified()`` as a public API to clear the type cache.
6790
6791- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00006792
6793- The PyString functions have been renamed to PyBytes. A batch of
6794 defines were added so that the linker still sees the original
6795 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006833- Issue #1631171: Re-implement the 'warnings' module in C (the
6834 original Python code has been kept as backup). This will allow for
6835 using the 'warning's machinery in such places as the parser where
6836 use of pure Python code is not possible. Both the ``showarning()``
6837 and ``formatwarning()`` gain an optional 'line' argument which is
6838 not called by default for backwards-compatibility reasons. Setting
6839 ``warnings.showwarning()`` to an implementation that lacks support
6840 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006865- The getpass module has been improved on Unix. It now uses /dev/tty
6866 by default and uses stderr instead of stdout. A GetPassWarning is
6867 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006882- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006883 extension modules between 32 and 64 bit platforms. See the distutls

6887 threads at once without fear of crashing the Python interpreter. If
6888 file.close() is called while an object is in use by another thread
6889 an IOError exception will be raised and the file will not be closed.
6890
Thomas Hellerf7906482008-04-04 19:43:25 +00006891- The bundled libffi copy is now in sync with the recently released

6896 so the controlled environment will more closely mirror the typical
6897 script environment. This supports setup.py scripts that refer to
6898 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006903- Issue #2550: The approach used by client/server code for obtaining
6904 ports to listen on in network-oriented tests has been refined in an
6905 effort to facilitate running multiple instances of the entire
6906 regression test suite in parallel without issue.
6907 test_support.bind_port() has been fixed such that it will always
6908 return a unique port -- which wasn't always the case with the
6909 previous implementation, especially if socket options had been set
6910 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6911 new implementation of bind_port() will actually raise an exception
6912 if it is passed an AF_INET/SOCK_STREAM socket with either the
6913 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6914 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6915 the socket it's been passed. This currently only applies to
6916 Windows. This option prevents any other sockets from binding to the
6917 host/port we've bound to, thus removing the possibility of the
6918 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6919 when a second SOCK_STREAM socket binds and accepts to a host/port
6920 that's already been bound by another socket. The optional preferred
6921 port parameter to bind_port() has been removed. Under no
6922 circumstances should tests be hard coding ports!
6923
6924 test_support.find_unused_port() has also been introduced, which will
6925 pass a temporary socket object to bind_port() in order to obtain an
6926 unused port. The temporary socket object is then closed and
6927 deleted, and the port is returned. This method should only be used
6928 for obtaining an unused port in order to pass to an external program
6929 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6930 a parameter to a server-oriented class that doesn't give you direct
6931 access to the underlying socket used.
6932
6933 Finally, test_support.HOST has been introduced, which should be used
6934 for the host argument of any relevant socket calls (i.e. bind and
6935 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006936
6937 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006938 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006939 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6940 test_asynchat and test_socket_ssl.
6941
Georg Brandl3ee81df2008-05-17 18:14:43 +00006942 It is now possible for multiple instances of the regression test
6943 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00007212- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007213 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00007222- Added the future_builtins module, which contains hex() and oct().
7223 These are the PEP 3127 version of these functions, designed to be
7224 compatible with the hex() and oct() builtins from Python 3.0. They
7225 differ slightly in their output formats from the existing, unchanged
7226 Python 2.6 builtins. The expected usage of the future_builtins
7227 module is:
7228 from future_builtins import hex, oct
7229
Eric Smith7ef40bf2008-02-20 23:34:22 +00007230- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7231 exponents for exponents with absolute value < 100. Follows C99
7232 standard. This is a change on Windows, which would use 3 digits.
7233 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7234 so that any alterations it does to the resulting string will be
7235 available in stringlib/formatter.h (for float.__format__).
7236
Eric Smith5a3c1352008-02-19 13:21:56 +00007237- Implemented PEP 3101, Advanced String Formatting. This adds a new
7238 builtin format(); a format() method for str and unicode; a
7239 __format__() method to object, str, unicode, int, long, float, and
7240 datetime; the class string.Formatter; and the C API
7241 PyObject_Format().
7242
Georg Brandl3ee81df2008-05-17 18:14:43 +00007243- Fixed several potential crashes, all caused by specially crafted
7244 __del__ methods exploiting objects in temporarily inconsistent
7245 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007246
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007247- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007248 prevent a possible crash: an Abstract Base Class would try to access
7249 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007254- Clear all free lists during a gc.collect() of the highest generation
7255 in order to allow pymalloc to free more arenas. Python may give back
7256 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007257
Georg Brandl3ee81df2008-05-17 18:14:43 +00007258- Issue #2045: Fix an infinite recursion triggered when printing a
7259 subclass of collections.defaultdict, if its default_factory is set
7260 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007261
Christian Heimesf75dbef2008-02-08 00:11:31 +00007262- Fixed a minor memory leak in dictobject.c. The content of the free
7263 list was not freed on interpreter shutdown.
7264
Georg Brandl21e99f42010-03-07 15:23:59 +00007265- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00007267
Georg Brandl3ee81df2008-05-17 18:14:43 +00007268- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7269 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007270 to compact the internal free lists of pre-allocted ints and floats.
7271
Georg Brandl3ee81df2008-05-17 18:14:43 +00007272- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7273 calls. Python expected the return type int but the fork familie
7274 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007275

Georg Brandl3ee81df2008-05-17 18:14:43 +00007288- Patch #1473257: generator objects gain a gi_code attribute. This is
7289 the same object as the func_code attribute of the function that
7290 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007291
Georg Brandl3ee81df2008-05-17 18:14:43 +00007292- Issue #1920: "while 0" statements were completely removed by the
7293 compiler, even in the presence of an "else" clause, which is

7295 correctly emits bytecode for the "else" suite.

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007301- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007302 suppressed while an extension is loaded by calling SetErrorMode in
7303 dynload_win.c. The error is still reported properly.
7304
Georg Brandl3ee81df2008-05-17 18:14:43 +00007305- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007306 several extension methods and modules do not work without unicode
7307 support.
7308
Georg Brandl26543b12008-01-21 18:36:51 +00007309- Issue #1882: when compiling code from a string, encoding cookies in the
7310 second line of code were not always recognized correctly.
7311
Georg Brandl14404b62008-01-19 19:27:05 +00007312- Issue #1679: "0x" was taken as a valid integer literal.
7313
Georg Brandl6caad7d2008-01-26 14:19:22 +00007314- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007315 added.
7316
Christian Heimesc94e2b52008-01-14 04:13:37 +00007317- sys.float_info / PyFloat_GetInfo: The floating point information
7318 object was converted from a dict to a specialized structseq object.
7319
Georg Brandl3ee81df2008-05-17 18:14:43 +00007320- Patch #1816: Added sys.flags structseq. It exposes the status of
7321 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007322
Georg Brandl3ee81df2008-05-17 18:14:43 +00007323- Objects/structseq.c: Implemented new structseq representation. The
7324 patch makes structseqs (e.g. the return value of os.stat) more
7325 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007326
Georg Brandl3ee81df2008-05-17 18:14:43 +00007327- Patch #1700288: added a type attribute cache that caches method
7328 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007329
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007330- Bug #1776: __import__() no longer accepts filenames on any platform.
7331 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007332
Georg Brandlaed6c662008-01-07 17:25:53 +00007333- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7334
Georg Brandl3ee81df2008-05-17 18:14:43 +00007335- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7336 envvar and sys.dont_write_bytecode attribute. All these can be set
7337 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007338
Georg Brandl3ee81df2008-05-17 18:14:43 +00007339- Improve some exception messages when Windows fails to load an
7340 extension module. Now we get for example '%1 is not a valid Win32
7341 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007342

Georg Brandl3ee81df2008-05-17 18:14:43 +00007345- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7346 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007347
Christian Heimes0a8143f2007-12-18 23:22:54 +00007348- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007349 and INF. float("nan"), float("inf") and float("-inf") now work on
7350 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007351
Georg Brandl3ee81df2008-05-17 18:14:43 +00007352- Compiler now generates simpler and faster code for dictionary
7353 literals. The oparg for BUILD_MAP now indicates an estimated
7354 dictionary size. There is a new opcode, STORE_MAP, for adding
7355 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007384- Patch #1739468: Directories and zipfiles containing a __main__.py
7385 file can now be directly executed by passing their name to the
7386 interpreter. The directory/zipfile is automatically inserted as the
7387 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007388
Georg Brandl3ee81df2008-05-17 18:14:43 +00007389- Issue #1265: Fix a problem with sys.settrace, if the tracing
7390 function uses a generator expression when at the same time the
7391 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007392
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007393- sets and frozensets now have an isdisjoint() method.
7394
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007395- optimize the performance of builtin.sum().
7396
Neal Norwitz44f326e2007-10-05 05:29:17 +00007397- Fix warnings found by the new version of the Coverity checker.
7398
Georg Brandl21e99f42010-03-07 15:23:59 +00007399- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007400 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7401 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007402
Georg Brandl3ee81df2008-05-17 18:14:43 +00007403- Issue #1686386: Tuple's tp_repr did not take into account the
7404 possibility of having a self-referential tuple, which is possible
7405 from C code. Nor did object's tp_str consider that a type's tp_str
7406 could do something that could lead to an inifinite recursion.
7407 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7408 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007409
Georg Brandl3ee81df2008-05-17 18:14:43 +00007410- Issue #1164: It was possible to trigger deadlock when using the
7411 'print' statement to write to a file since the GIL was not released
7412 as needed. Now PyObject_Print() does the right thing along with
7413 various tp_print implementations of the built-in types and those in
7414 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007415
Georg Brandl3ee81df2008-05-17 18:14:43 +00007416- Issue #1147: Exceptions were directly allowing string exceptions in
7417 their throw() method even though string exceptions no longer
7418 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007419
Georg Brandl3ee81df2008-05-17 18:14:43 +00007420- Issue #1096: Prevent a segfault from getting the repr of a very
7421 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007422
Brett Cannon1e534b52007-09-07 04:18:30 +00007423- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007424 PyObject_Call() never calling back out to Python code to trigger
7425 recursion depth updates/checks. Required the creation of a static
7426 RuntimeError instance in case normalizing an exception put the
7427 recursion check value past its limit. Fixes crashers
7428 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007429
Georg Brandl3ee81df2008-05-17 18:14:43 +00007430- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007443- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007444 __*__ attributes. (Some already existed, e.g., __doc__ and
7445 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007446
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007447- Add -3 option to the interpreter to warn about features that are
7448 deprecated and will be changed/removed in Python 3.0.
7449
Georg Brandl2134e752007-05-21 20:34:16 +00007450- Patch #1686487: you can now pass any mapping after '**' in function
7451 calls.
7452
Collin Winter62903052007-05-18 23:11:24 +00007453- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007454 "except E as target:". This is to provide forwards compatibility
7455 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007456
Brett Cannon229cee22007-05-05 01:34:02 +00007457- Deprecate BaseException.message as per PEP 352.
7458
Georg Brandl3ee81df2008-05-17 18:14:43 +00007459- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007460 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007461
Vinay Sajip8549ce32007-05-06 17:53:37 +00007462- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007463 setting a plain string, ie don't expand to single letter identifiers.
7464
Raymond Hettinger13936692007-04-11 18:40:58 +00007465- Request #1191699: Slices can now be pickled.
7466
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007467- Request #1193128: str.translate() now allows a None argument for
7468 translations that only remove characters without re-mapping the
7469 remaining characters.
7470
Georg Brandl5cb76c12007-03-21 09:00:39 +00007471- Patch #1682205: a TypeError while unpacking an iterable is no longer
7472 masked by a generic one with the message "unpack non-sequence".
7473
Neal Norwitzaa754b72007-03-21 06:39:48 +00007474- Remove unused file Python/fmod.c.
7475
Guido van Rossum143b5642007-03-23 04:58:42 +00007476- Bug #1683368: The object.__init__() and object.__new__() methods are
7477 now stricter in rejecting excess arguments. The only time when
7478 either allows excess arguments is when it is not overridden and the
7479 other one is. For backwards compatibility, when both are
7480 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007481 warning later). Also, type.__init__() insists on the same signature
7482 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007483
Georg Brandl3ee81df2008-05-17 18:14:43 +00007484- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7485 object to complex using its __complex__() method before falling back
7486 to the __float__() method. Therefore, the functions in the cmath
7487 module now can operate on objects that define a __complex__()
7488 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007489
Georg Brandl3ee81df2008-05-17 18:14:43 +00007490- Patch #1623563: allow __class__ assignment for classes with
7491 __slots__. The old and the new class are still required to have the
7492 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007493

Georg Brandl3ee81df2008-05-17 18:14:43 +00007497- Patch #1462488: Python no longer segfaults when
7498 ``object.__reduce_ex__()`` is called with an object that is faking
7499 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007500
Georg Brandl3ee81df2008-05-17 18:14:43 +00007501- Patch #1680015: Don't modify __slots__ tuple if it contains an

7505
Georg Brandl7b9c5552007-03-12 14:30:05 +00007506- Bug #1678647: write a newline after printing an exception in any
7507 case, even when converting the value to a string failed.
7508
Georg Brandl871f1bc2007-03-12 13:17:36 +00007509- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007510 its argument, if it exists. If not, it will work like before. This
7511 allows customizing the output of dir() in the presence of a
7512 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00007514- Patch #922167: Python no longer segfaults when faced with infinitely
7515 self-recursive reload() calls (as reported by bug #742342).
7516
Georg Brandl3ee81df2008-05-17 18:14:43 +00007517- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007520- Patch #1491866: change the complex() constructor to allow
7521 parthensized forms. This means complex(repr(x)) now works instead of
7522 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007523
Georg Brandlaa2321b2007-03-07 00:40:28 +00007524- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007525 makes the filenames the warning module prints much more sensible
7526 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007527
Georg Brandl49aafc92007-03-07 00:34:46 +00007528- Variant of patch #697613: don't exit the interpreter on a SystemExit
7529 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007530 variable is given, but break into the interactive interpreter just
7531 like on other exceptions or normal program exit.

8034
Facundo Batistad918a652007-04-24 13:54:38 +00008035- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008036 the client's request was successfully received, understood, and
8037 accepted. Now in these cases no error is raised in urllib (issue
8038 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008046- Added a timeout parameter to the constructor of other protocols
8047 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8048 work started with create_connection() and timeout in httplib, and
8049 closes patch #723312.
8050
Vinay Sajip8549ce32007-05-06 17:53:37 +00008051- Patch #1676823: Added create_connection() to socket.py, which may be

8075
Georg Brandlf66b6032007-03-14 08:27:52 +00008076- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008077 AttributeError instead of an IOError when the server's response
8078 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008079
Georg Brandl3ee81df2008-05-17 18:14:43 +00008080- Patch #957650: "%var%" environment variable references are now
8081 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00008084- Patch #1429539: pdb now correctly initializes the __main__ module
8085 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008086 correctly now.
8087

8094
Georg Brandl3ee81df2008-05-17 18:14:43 +00008095- Patch #1530482: add pydoc.render_doc() which returns the
8096 documentation for a thing instead of paging it to stdout, which

8110
Georg Brandl92a6bae2007-03-13 17:43:32 +00008111- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008112 are set for invalid interpolation sequences that would lead to
8113 errors on reading back those values.

8156 returned string up to the first NUL character.

8167
Georg Brandl3ee81df2008-05-17 18:14:43 +00008168- unittest now verifies more of its assumptions. In particular,
8169 TestCase and TestSuite subclasses (not instances) are no longer
8170 accepted in TestSuite.addTest(). This should cause no
8171 incompatibility since it never made sense with ordinary subclasses
8172 -- the failure just occurred later, with a more cumbersome
8173 exception.

8182 given a unicode argument and os.listdir() returns unicode filenames.
8183
Georg Brandl3ee81df2008-05-17 18:14:43 +00008184- Patch #1673619: setup.py identifies extension modules it doesn't

8186 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008562 time so that opening a database previously created with the DB_DUP
8563 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8564 opens. Specifically: dictionary assignment to a DB object will
8565 replace all values for a given key when the database allows
8566 duplicate values. DB users should use DB.put(k, v) when they want
8567 to store duplicates; not DB[k] = v.

8574 characters with ASCII value less than 32. Also, it correctly quotes
8575 dots only if they occur on a single line, as opposed to the previous
8576 behavior of quoting dots if they are the second character of any
8577 line.
