136
Ned Deily87e82bb2011-06-28 19:52:59 -0700137- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
138 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
139 interpreter process. This could cause failures in non-Distutils subprocesses
140 and was unreliable since tests or user programs could modify the interpreter
141 environment after Distutils set it. Instead, have Distutils set the the
142 deployment target only in the environment of each build subprocess. It is
143 still possible to globally override the default by setting
144 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
145 greater or equal to the default value, the value with which the interpreter
146 was built.

152 Kitada.
153
R David Murrayf1138bb2011-06-17 22:23:04 -0400154- Issue #11700: mailbox proxy object close methods can now be called multiple
155 times without error, and _ProxyFile now closes the wrapped file.
156
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200157- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
158 connection if its getresponse() method fails with a socket error. Patch
159 written by Ezio Melotti.
160
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500161- Issue #9284: Allow inspect.findsource() to find the source of doctest

163

170 some corner-case Decimal.__pow__ calls to take an unreasonably long time.
171
Raymond Hettinger45b08292011-06-02 20:40:35 -0700172- Named tuples now work correctly with vars().
173
Barry Warsawc5643282011-07-19 17:06:30 -0400174- sys.setcheckinterval() now updates the current ticker count as well as
175 updating the check interval, so if the user decreases the check interval,
176 the ticker doesn't have to wind down to zero from the old starting point
177 before the new interval takes effect. And if the user increases the
178 interval, it makes sure the new limit takes effect right away rather have an
179 early task switch before recognizing the new interval.

1043 This prevents user-created self-referencing ordered dictionaries from
1044 becoming permanently uncollectable GC garbage. The downside is that

1504-----------------
1505
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001506- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1507 start byte and the continuation byte(s) are now considered invalid, instead
1508 of the number of bytes specified by the start byte.
1509 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1510 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1511 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1512 Previous versions returned a single u'\ufffd'.
1513
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001514- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001515 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1516 arises from the "Overriding __eq__ blocks inheritance ..." warning
1517 when turned into an exception: in this case the exception simply
1518 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001519
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001520- Issue #8748: Fix two issues with comparisons between complex and integer
1521 objects. (1) The comparison could incorrectly return True in some cases
1522 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1523 (2) The comparison raised an OverflowError for large integers, leading
1524 to unpredictable exceptions when combining integers and complex objects
1525 in sets or dicts.
1526
Mark Dickinson81336372010-05-30 12:12:25 +00001527- Issue #5211: Implicit coercion for the complex type is now completely
1528 removed. (Coercion for arithmetic operations was already removed in 2.7
1529 alpha 4, but coercion for rich comparisons was accidentally left in.)
1530
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001531- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1532 and error handler, instead of writing to the C stderr file in utf-8
1533
Georg Brandlfee0f442010-05-22 21:26:21 +00001534- Issue #7902: When using explicit relative import syntax, don't try implicit
1535 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00001536
Georg Brandlfee0f442010-05-22 21:26:21 +00001537- Issue #7079: Fix a possible crash when closing a file object while using it
1538 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +00001539
Victor Stinnerb65bd2e2010-06-11 19:22:28 +00001540- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00001541 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +00001546- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
1547 of the interpreter to set sys.argv without also modifying sys.path. This
1548 helps fix `CVE-2008-5983

1665 non-float non-integer argument is now converted to an integer (if possible)
1666 using its __int__ method. Previously, only small arguments were treated this
1667 way; larger arguments (those whose __int__ was outside the range of a C long)

1908 with a non-empty format string. This is an effort to future-proof user
1909 code. If a derived class does not currently implement __format__ but later
1910 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001911 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001912 Python 3.3 and it will be an error in Python 3.4.

2345 and add the additional members returned in an OSVERSIONINFOEX structure. The
2346 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002349- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2350 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2351 returning NULL. The macro now returns a statically allocated empty string
2352 instead.

2362 strings,
2363 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2364 numeric strings corresponding to subnormal values,
2365 (3) a memory leak for some values large enough to cause overflow, and
2366 (4) a number of flaws that could lead to incorrectly rounded results.

2385
Georg Brandlba83f822010-03-14 09:50:54 +00002386- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00002397- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002398 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002399 Also, raise ValueError rather than TypeError when an unknown TIPC address
2400 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002404- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002405 file position when calling `truncate()`. It would previously change the file
2406 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002407 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2408
Georg Brandlba83f822010-03-14 09:50:54 +00002409- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2410 class used to represent files stored inside an archive. The new
2411 implementation is significantly faster and can be wrapped in a
2412 ``io.BufferedReader`` object for more speedups. It also solves an issue
2413 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2414 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002424- Issue #7748: Since unicode values are supported for some metadata options in
2425 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2426 encoded string for them. This ensures that the upload and register commands
2427 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002504- The ``__complex__()`` method is now looked up on the class of instances to
2505 make it consistent with other special methods.

2509
Mark Dickinson1b34d252010-01-01 17:27:30 +00002510- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002511 DeprecationWarning when passed a float argument where an integer was expected.
2512 These functions and methods now raise TypeError instead. The majority of the
2513 effects of this change are in the extension modules, but some core functions
2514 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2515 and many unicode/str methods.

2530 least on IEEE 754 platforms), and in particular does not depend on the
2531 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00002540 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002698- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2699 decimal string that's guaranteed to round back to x under correct rounding
2700 (with round-half-to-even rounding mode). Previously it gave a string based on
2701 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2702 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2703 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002705- Issue #7117: On almost all platforms: float-to-string and string-to-float
2706 conversions within Python are now correctly rounded. Places these conversions
2707 occur include: str for floats and complex numbers; the float and complex
2708 constructors; old-style and new-style numeric formatting; serialization and
2709 deserialization of floats and complex numbers using marshal, pickle and json;
2710 parsing of float and imaginary literals in Python code; Decimal-to-float
2711 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002712
Georg Brandlba83f822010-03-14 09:50:54 +00002713 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2714 providing correctly-rounded strtod and dtoa C functions. This code is
2715 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2716 the C compiler. There may be a small number of platforms on which correct
2717 operation of this code cannot be guaranteed, so the code is not used: notably,
2718 this applies to platforms where the C double format is not IEEE 754 binary64,
2719 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2720 and Python's configure script is unable to determine how to change the FPU
2721 precision. On these platforms conversions use the platform strtod and dtoa,
2722 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002724- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2725 uses the correctly-rounded string <-> float conversions described above (when
2726 available), and so produces correctly rounded results that will display nicely
2727 under the float repr. There are two related small changes: (1) round now
2728 accepts any class with an ``__index__()`` method for its second argument (but
2729 no longer accepts floats for the second argument), and (2) an excessively
2730 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2731 raises an exception.

4516 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4517 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitrou0668c622008-08-26 22:42:08 +00004540 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4541 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4542 when given a tuple of classes as second argument, were looking up
4543 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4544 type object.
4545

4555 function 'stringlib_contains_obj'.
4556
Benjamin Peterson712ee922008-08-24 18:10:20 +00004557- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00004615 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4616 for catch_warnings() also led to an improvement in the raising of a
4617 DeprecationWarning related to warnings.warn_explicit().
4618

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004683What's New in Python 2.6 beta 3?
4684================================
4685
Barry Warsaw07a4a382008-08-21 01:15:08 +00004686*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004687
4688Core and Builtins
4689-----------------
4690
Guido van Rossumf8402962008-08-20 15:01:50 +00004691- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4692 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4693 extensions do not automatically benefit from the class attribute
4694 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4695 to their tp_flags field if they care. This is a backwards
4696 compatibility feature; in 3.0, all types will use the cache by
4697 default.
4698
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004699- Keyword arguments can now follow starred arguments. (``f(a, *args,
4700 keyword=23)`` is now valid syntax.)
4701
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004702- ctypes function pointers that are COM methods have a boolean True
4703 value again.
4704
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004705- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4706 by denying s# to parse objects that have a releasebuffer procedure,
4707 and introducing s*.
4708
Georg Brandl1e13ea92008-08-11 09:07:59 +00004709- Issue #3537: Fix an assertion failure when an empty but presized dict
4710 object was stored in the freelist.
4711
Mark Dickinsonb6467572008-08-04 21:30:09 +00004712- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4713 ValueError consistently across platforms.
4714
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004715- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4716 (64bit Unix, for example), unichr() would truncate its argument and return
4717 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4718
Neal Norwitze7d8be82008-07-31 17:17:14 +00004719- Apply security patches from Apple.
4720
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004721- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4722 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4723
Antoine Pitrou92f82162008-07-25 22:22:08 +00004724- Issue #1819: function calls with several named parameters are now on
4725 average 35% faster (as measured by pybench).
4726
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004727- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4728 the python debugger steps into a class statement: the free variables (local
4729 variables defined in an outer scope) would be deleted from the outer scope.
4730
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004731- Issue #2620: Overflow checking when allocating or reallocating memory
4732 was not always being done properly in some python types and extension
4733 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4734 all been updated to perform better checks and places in the code that
4735 would previously leak memory on the error path when such an allocation
4736 failed have been fixed.

4739-------
4740
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004741- Issue #3612: Added some missing basic types in ctypes.wintypes.
4742
Benjamin Petersone977ad42008-08-20 01:42:01 +00004743- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4744 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4745
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004746- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4747 version reported by these tools does not necessarily follow the python
4748 version numbering scheme, so the module is less strict when parsing it.
4749
Nick Coghlanf70385a2008-08-18 12:42:46 +00004750- Issue #2235: Added Py3k warnings for types which will become unhashable
4751 under the stricter __hash__ inheritance rules in 3.0. Several types
4752 which did not meet the rules for hash invariants and were already
4753 unhashable in 3.0 have now been explicitly flagged as unhashable in
4754 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4755 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4756
Brett Cannon88f801d2008-08-18 00:46:22 +00004757- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4758 imported into the module but exposed as part of the module's API.
4759
Brett Cannon7b96f072008-08-18 00:41:11 +00004760- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4761
Brett Cannon46225e72008-08-18 00:36:52 +00004762- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004764- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4765
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004766- Issue #3575: Incremental decoder's decode function now takes bytearray
4767 by using 's*' instead of 't#'.
4768
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004769- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004770 fails unicode conversion on 2nd parameter. (windows only)
4771
Georg Brandl222e2082010-08-01 22:27:39 +00004772- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004773 in a redirect.
4774
Brett Cannonabe423e2008-08-16 21:47:07 +00004775- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004776 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004777
Facundo Batistaeb90b782008-08-16 14:44:07 +00004778- Issue #2776: fixed small issue when handling an URL with double slash
4779 after a 302 response in the case of not going through a proxy.
4780
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004781- Issue #2676: in the email package, content-type parsing was hanging on
4782 pathological input because of quadratic or exponential behaviour of a
4783 regular expression.
4784
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004785- Issue #3476: binary buffered reading through the new "io" library is now
4786 thread-safe.
4787
Brett Cannonbf3157b2008-08-14 05:00:03 +00004788- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4789 since mimetools itself is deprecated. Because modules are cached, all
4790 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4791
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004792- Issue #3134: shutil referenced undefined WindowsError symbol.
4793
Robert Schuppenies14646332008-08-10 11:01:53 +00004794- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4795 menu entries were not deleted.
4796
Brett Cannon83e81842008-08-09 23:30:55 +00004797- Copied the implementation of reduce() to _functools.reduce() to have a
4798 version that did not raise a DeprecationWarning under -3.
4799
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004800- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4801 a MemoryError rather than silently stop the iteration.
4802
Guido van Rossum59ce9012008-08-09 14:55:34 +00004803- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4804 to _sre.compile() will now be rejected. This should not affect anybody
4805 since the re.compile() function never generates invalid re-bytecode.
4806
Skip Montanaroa032bf42008-08-08 22:52:51 +00004807- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4808 upon first access it can be automatically initialized from the csv file if
4809 it wasn't initialized during instantiation.
4810
Brett Cannon3aa2a492008-08-06 22:28:09 +00004811- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4812 the reload() built-in has been removed.
4813
Brett Cannon7e30b672008-08-04 21:52:25 +00004814- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004815 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4883-----------------
4884
Georg Brandl3e483f62008-07-16 22:57:41 +00004885- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4886 its methods now allow for items objects that can be converted to
4887 an integer using operator.index().
4888
Mark Dickinson64b7e502008-07-16 09:40:03 +00004889- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4890 produced a ValueError instead of giving the correct float.
4891
Eric Smitha5fa5a22008-07-16 00:11:49 +00004892- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4893 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4894
Mark Dickinson7103aa42008-07-15 19:08:33 +00004895- Issue #3008: the float type has a new instance method 'float.hex'
4896 and a new class method 'float.fromhex' to convert floating-point
4897 numbers to and from hexadecimal strings, respectively.
4898
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004899- Issue #2235: __hash__ is once again inherited by default. To allow
4900 collections.Hashable to remain meaningful in the presence of the
4901 default hash implementation (object.__hash__), it is now possible
4902 to explicit block inheritance of hash by setting __hash__=None at
4903 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4904 level.
4905
Nick Coghlanb028f502008-07-13 14:52:36 +00004906- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4907 the parent module cannot be found while performing an absolute import.
4908 This means that an incorrectly defined __package__ attribute will
4909 now only prevent relative imports in that module rather than causing
4910 all imports from that module to fail.
4911
Nick Coghlan14ff9942008-07-08 14:21:42 +00004912- Issue #2517: Allow unicode messages in Exceptions again by correctly

4922 another thread's dictionary.
4923
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004924- Issue #3004: Minor change to slice.indices(): the start and stop
4925 arguments are now treated identically, making the behaviour easier
4926 to describe and understand. For example, slice(None, -10,
4927 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4928 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4929 10, -1).
4930
Georg Brandl278fc502008-07-19 12:46:12 +00004931- Issue #3219: Calling a function with repeated keyword arguments,
4932 f(a=2, a=23), would not cause a syntax error. This was a regression
4933 from 2.4 caused by the switch to the new compiler.

4972 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004973 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004974 content-length. The problem had been corrected in the 2.4 branch, but never
4975 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004990- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl74a1dea2008-05-28 11:21:39 +00005401- Add ``PyType_Modified()`` as a public API to clear the type cache.
5402
5403- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00005404
5405- The PyString functions have been renamed to PyBytes. A batch of
5406 defines were added so that the linker still sees the original
5407 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005445- Issue #1631171: Re-implement the 'warnings' module in C (the
5446 original Python code has been kept as backup). This will allow for
5447 using the 'warning's machinery in such places as the parser where
5448 use of pure Python code is not possible. Both the ``showarning()``
5449 and ``formatwarning()`` gain an optional 'line' argument which is
5450 not called by default for backwards-compatibility reasons. Setting
5451 ``warnings.showwarning()`` to an implementation that lacks support
5452 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005495 extension modules between 32 and 64 bit platforms. See the distutls

5508 so the controlled environment will more closely mirror the typical
5509 script environment. This supports setup.py scripts that refer to
5510 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005515- Issue #2550: The approach used by client/server code for obtaining
5516 ports to listen on in network-oriented tests has been refined in an
5517 effort to facilitate running multiple instances of the entire
5518 regression test suite in parallel without issue.
5519 test_support.bind_port() has been fixed such that it will always
5520 return a unique port -- which wasn't always the case with the
5521 previous implementation, especially if socket options had been set
5522 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5523 new implementation of bind_port() will actually raise an exception
5524 if it is passed an AF_INET/SOCK_STREAM socket with either the
5525 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5526 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5527 the socket it's been passed. This currently only applies to
5528 Windows. This option prevents any other sockets from binding to the
5529 host/port we've bound to, thus removing the possibility of the
5530 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5531 when a second SOCK_STREAM socket binds and accepts to a host/port
5532 that's already been bound by another socket. The optional preferred
5533 port parameter to bind_port() has been removed. Under no
5534 circumstances should tests be hard coding ports!
5535
5536 test_support.find_unused_port() has also been introduced, which will
5537 pass a temporary socket object to bind_port() in order to obtain an
5538 unused port. The temporary socket object is then closed and
5539 deleted, and the port is returned. This method should only be used
5540 for obtaining an unused port in order to pass to an external program
5541 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5542 a parameter to a server-oriented class that doesn't give you direct
5543 access to the underlying socket used.
5544
5545 Finally, test_support.HOST has been introduced, which should be used
5546 for the host argument of any relevant socket calls (i.e. bind and
5547 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005548
5549 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005550 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005551 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5552 test_asynchat and test_socket_ssl.
5553
Georg Brandl3ee81df2008-05-17 18:14:43 +00005554 It is now possible for multiple instances of the regression test
5555 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005834- Added the future_builtins module, which contains hex() and oct().
5835 These are the PEP 3127 version of these functions, designed to be
5836 compatible with the hex() and oct() builtins from Python 3.0. They
5837 differ slightly in their output formats from the existing, unchanged
5838 Python 2.6 builtins. The expected usage of the future_builtins
5839 module is:
5840 from future_builtins import hex, oct
5841
Eric Smith7ef40bf2008-02-20 23:34:22 +00005842- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5843 exponents for exponents with absolute value < 100. Follows C99
5844 standard. This is a change on Windows, which would use 3 digits.
5845 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5846 so that any alterations it does to the resulting string will be
5847 available in stringlib/formatter.h (for float.__format__).
5848
Eric Smith5a3c1352008-02-19 13:21:56 +00005849- Implemented PEP 3101, Advanced String Formatting. This adds a new
5850 builtin format(); a format() method for str and unicode; a
5851 __format__() method to object, str, unicode, int, long, float, and
5852 datetime; the class string.Formatter; and the C API
5853 PyObject_Format().
5854
Georg Brandl3ee81df2008-05-17 18:14:43 +00005855- Fixed several potential crashes, all caused by specially crafted
5856 __del__ methods exploiting objects in temporarily inconsistent
5857 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005858
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005859- Issue #2115: Important speedup in setting __slot__ attributes. Also

Georg Brandl3ee81df2008-05-17 18:14:43 +00005866- Clear all free lists during a gc.collect() of the highest generation
5867 in order to allow pymalloc to free more arenas. Python may give back
5868 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005869
Georg Brandl3ee81df2008-05-17 18:14:43 +00005870- Issue #2045: Fix an infinite recursion triggered when printing a
5871 subclass of collections.defaultdict, if its default_factory is set
5872 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005873
Christian Heimesf75dbef2008-02-08 00:11:31 +00005874- Fixed a minor memory leak in dictobject.c. The content of the free

Christian Heimes6075a822008-02-06 12:44:34 +00005879
Georg Brandl3ee81df2008-05-17 18:14:43 +00005880- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5881 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005882 to compact the internal free lists of pre-allocted ints and floats.
5883
Georg Brandl3ee81df2008-05-17 18:14:43 +00005884- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5885 calls. Python expected the return type int but the fork familie
5886 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005887

Georg Brandl3ee81df2008-05-17 18:14:43 +00005900- Patch #1473257: generator objects gain a gi_code attribute. This is
5901 the same object as the func_code attribute of the function that
5902 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005903
Georg Brandl3ee81df2008-05-17 18:14:43 +00005904- Issue #1920: "while 0" statements were completely removed by the
5905 compiler, even in the presence of an "else" clause, which is

5907 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00005909- A few crashers fixed: weakref_in_del.py (issue #1377858);
5910 loosing_dict_ref.py (issue #1303614, test67.py);
5911 borrowed_ref_[34].py (not in tracker).
5912
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005913- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005914 suppressed while an extension is loaded by calling SetErrorMode in
5915 dynload_win.c. The error is still reported properly.
5916
Georg Brandl3ee81df2008-05-17 18:14:43 +00005917- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005918 several extension methods and modules do not work without unicode
5919 support.
5920
Georg Brandl26543b12008-01-21 18:36:51 +00005921- Issue #1882: when compiling code from a string, encoding cookies in the
5922 second line of code were not always recognized correctly.
5923
Georg Brandl14404b62008-01-19 19:27:05 +00005924- Issue #1679: "0x" was taken as a valid integer literal.
5925
Georg Brandl6caad7d2008-01-26 14:19:22 +00005926- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005927 added.
5928
Christian Heimesc94e2b52008-01-14 04:13:37 +00005929- sys.float_info / PyFloat_GetInfo: The floating point information
5930 object was converted from a dict to a specialized structseq object.
5931
Georg Brandl3ee81df2008-05-17 18:14:43 +00005932- Patch #1816: Added sys.flags structseq. It exposes the status of
5933 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005934
Georg Brandl3ee81df2008-05-17 18:14:43 +00005935- Objects/structseq.c: Implemented new structseq representation. The
5936 patch makes structseqs (e.g. the return value of os.stat) more
5937 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005938
Georg Brandl3ee81df2008-05-17 18:14:43 +00005939- Patch #1700288: added a type attribute cache that caches method
5940 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005941
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005942- Bug #1776: __import__() no longer accepts filenames on any platform.
5943 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005944
Georg Brandlaed6c662008-01-07 17:25:53 +00005945- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5946
Georg Brandl3ee81df2008-05-17 18:14:43 +00005947- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5948 envvar and sys.dont_write_bytecode attribute. All these can be set
5949 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005950
Georg Brandl3ee81df2008-05-17 18:14:43 +00005951- Improve some exception messages when Windows fails to load an
5952 extension module. Now we get for example '%1 is not a valid Win32
5953 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005954

5958 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005959
Christian Heimes0a8143f2007-12-18 23:22:54 +00005960- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005961 and INF. float("nan"), float("inf") and float("-inf") now work on
5962 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005963
Georg Brandl3ee81df2008-05-17 18:14:43 +00005964- Compiler now generates simpler and faster code for dictionary
5965 literals. The oparg for BUILD_MAP now indicates an estimated
5966 dictionary size. There is a new opcode, STORE_MAP, for adding
5967 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005996- Patch #1739468: Directories and zipfiles containing a __main__.py
5997 file can now be directly executed by passing their name to the
5998 interpreter. The directory/zipfile is automatically inserted as the
5999 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006000
Georg Brandl3ee81df2008-05-17 18:14:43 +00006001- Issue #1265: Fix a problem with sys.settrace, if the tracing
6002 function uses a generator expression when at the same time the
6003 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006004
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006005- sets and frozensets now have an isdisjoint() method.
6006
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006007- optimize the performance of builtin.sum().
6008
Neal Norwitz44f326e2007-10-05 05:29:17 +00006009- Fix warnings found by the new version of the Coverity checker.
6010
Georg Brandl21e99f42010-03-07 15:23:59 +00006011- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006012 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6013 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006014
Georg Brandl3ee81df2008-05-17 18:14:43 +00006015- Issue #1686386: Tuple's tp_repr did not take into account the
6016 possibility of having a self-referential tuple, which is possible
6017 from C code. Nor did object's tp_str consider that a type's tp_str
6018 could do something that could lead to an inifinite recursion.
6019 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6020 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006021
Georg Brandl3ee81df2008-05-17 18:14:43 +00006022- Issue #1164: It was possible to trigger deadlock when using the
6023 'print' statement to write to a file since the GIL was not released
6024 as needed. Now PyObject_Print() does the right thing along with
6025 various tp_print implementations of the built-in types and those in
6026 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006027
Georg Brandl3ee81df2008-05-17 18:14:43 +00006028- Issue #1147: Exceptions were directly allowing string exceptions in
6029 their throw() method even though string exceptions no longer
6030 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006031
Georg Brandl3ee81df2008-05-17 18:14:43 +00006032- Issue #1096: Prevent a segfault from getting the repr of a very
6033 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006034
Brett Cannon1e534b52007-09-07 04:18:30 +00006035- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006036 PyObject_Call() never calling back out to Python code to trigger
6037 recursion depth updates/checks. Required the creation of a static
6038 RuntimeError instance in case normalizing an exception put the
6039 recursion check value past its limit. Fixes crashers
6040 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006041
Georg Brandl3ee81df2008-05-17 18:14:43 +00006042- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006055- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006056 __*__ attributes. (Some already existed, e.g., __doc__ and
6057 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006058
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006059- Add -3 option to the interpreter to warn about features that are
6060 deprecated and will be changed/removed in Python 3.0.
6061
Georg Brandl2134e752007-05-21 20:34:16 +00006062- Patch #1686487: you can now pass any mapping after '**' in function
6063 calls.
6064
Collin Winter62903052007-05-18 23:11:24 +00006065- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006066 "except E as target:". This is to provide forwards compatibility
6067 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006068
Brett Cannon229cee22007-05-05 01:34:02 +00006069- Deprecate BaseException.message as per PEP 352.
6070
Georg Brandl3ee81df2008-05-17 18:14:43 +00006071- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006072 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006073
Vinay Sajip8549ce32007-05-06 17:53:37 +00006074- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006075 setting a plain string, ie don't expand to single letter identifiers.
6076
Raymond Hettinger13936692007-04-11 18:40:58 +00006077- Request #1191699: Slices can now be pickled.
6078
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006079- Request #1193128: str.translate() now allows a None argument for
6080 translations that only remove characters without re-mapping the
6081 remaining characters.
6082
Georg Brandl5cb76c12007-03-21 09:00:39 +00006083- Patch #1682205: a TypeError while unpacking an iterable is no longer
6084 masked by a generic one with the message "unpack non-sequence".
6085
Neal Norwitzaa754b72007-03-21 06:39:48 +00006086- Remove unused file Python/fmod.c.
6087
Guido van Rossum143b5642007-03-23 04:58:42 +00006088- Bug #1683368: The object.__init__() and object.__new__() methods are
6089 now stricter in rejecting excess arguments. The only time when
6090 either allows excess arguments is when it is not overridden and the
6091 other one is. For backwards compatibility, when both are
6092 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006093 warning later). Also, type.__init__() insists on the same signature
6094 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006095
Georg Brandl3ee81df2008-05-17 18:14:43 +00006096- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6097 object to complex using its __complex__() method before falling back
6098 to the __float__() method. Therefore, the functions in the cmath
6099 module now can operate on objects that define a __complex__()
6100 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006101
Georg Brandl3ee81df2008-05-17 18:14:43 +00006102- Patch #1623563: allow __class__ assignment for classes with
6103 __slots__. The old and the new class are still required to have the
6104 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006105

6110 ``object.__reduce_ex__()`` is called with an object that is faking
6111 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006112
Georg Brandl3ee81df2008-05-17 18:14:43 +00006113- Patch #1680015: Don't modify __slots__ tuple if it contains an

6117
Georg Brandl7b9c5552007-03-12 14:30:05 +00006118- Bug #1678647: write a newline after printing an exception in any
6119 case, even when converting the value to a string failed.
6120
Georg Brandl871f1bc2007-03-12 13:17:36 +00006121- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006122 its argument, if it exists. If not, it will work like before. This
6123 allows customizing the output of dir() in the presence of a
6124 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006125
Collin Winter276887b2007-03-12 16:11:39 +00006126- Patch #922167: Python no longer segfaults when faced with infinitely

Georg Brandl3ee81df2008-05-17 18:14:43 +00006132- Patch #1491866: change the complex() constructor to allow
6133 parthensized forms. This means complex(repr(x)) now works instead of
6134 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006135
Georg Brandlaa2321b2007-03-07 00:40:28 +00006136- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006137 makes the filenames the warning module prints much more sensible
6138 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006139
Georg Brandl49aafc92007-03-07 00:34:46 +00006140- Variant of patch #697613: don't exit the interpreter on a SystemExit
6141 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006142 variable is given, but break into the interactive interpreter just
6143 like on other exceptions or normal program exit.

6645 ".cpp" too.
6646
Facundo Batistad918a652007-04-24 13:54:38 +00006647- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006648 the client's request was successfully received, understood, and
6649 accepted. Now in these cases no error is raised in urllib (issue
6650 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00006651

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006658- Added a timeout parameter to the constructor of other protocols
6659 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6660 work started with create_connection() and timeout in httplib, and
6661 closes patch #723312.
6662
Vinay Sajip8549ce32007-05-06 17:53:37 +00006663- Patch #1676823: Added create_connection() to socket.py, which may be
6664 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00006666
Martin v. Löwis0af33882007-03-23 13:27:15 +00006667- Bug #978833: Revert r50844, as it broke _socketobject.dup.

6687
Georg Brandlf66b6032007-03-14 08:27:52 +00006688- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006689 AttributeError instead of an IOError when the server's response
6690 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006691
Georg Brandl3ee81df2008-05-17 18:14:43 +00006692- Patch #957650: "%var%" environment variable references are now
6693 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00006695
Georg Brandl3ee81df2008-05-17 18:14:43 +00006696- Patch #1429539: pdb now correctly initializes the __main__ module
6697 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006698 correctly now.
6699

6706
Georg Brandl3ee81df2008-05-17 18:14:43 +00006707- Patch #1530482: add pydoc.render_doc() which returns the
6708 documentation for a thing instead of paging it to stdout, which
6709 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00006710
Georg Brandl3ee81df2008-05-17 18:14:43 +00006711- Patch #1533909: the timeit module now accepts callables in addition

6718 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00006720- Patch #1581073: add a flag to textwrap that prevents the dropping of
6721 whitespace while wrapping.
6722
Georg Brandl92a6bae2007-03-13 17:43:32 +00006723- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006724 are set for invalid interpolation sequences that would lead to
6725 errors on reading back those values.

Collin Winter22c42ba2007-03-10 02:51:26 +00006760

6768 returned string up to the first NUL character.
6769

6779
Georg Brandl3ee81df2008-05-17 18:14:43 +00006780- unittest now verifies more of its assumptions. In particular,
6781 TestCase and TestSuite subclasses (not instances) are no longer
6782 accepted in TestSuite.addTest(). This should cause no
6783 incompatibility since it never made sense with ordinary subclasses
6784 -- the failure just occurred later, with a more cumbersome
6785 exception.

6794 given a unicode argument and os.listdir() returns unicode filenames.
6795
Georg Brandl3ee81df2008-05-17 18:14:43 +00006796- Patch #1673619: setup.py identifies extension modules it doesn't
6797 know how to build and those it knows how to build but that fail to
6798 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007174 time so that opening a database previously created with the DB_DUP
7175 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7176 opens. Specifically: dictionary assignment to a DB object will
7177 replace all values for a given key when the database allows
7178 duplicate values. DB users should use DB.put(k, v) when they want
7179 to store duplicates; not DB[k] = v.

7186 characters with ASCII value less than 32. Also, it correctly quotes
7187 dots only if they occur on a single line, as opposed to the previous
7188 behavior of quoting dots if they are the second character of any
7189 line.
