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

753 GC collection rather than freeing memory immediately when the refcnt drops
754 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001213- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1214 start byte and the continuation byte(s) are now considered invalid, instead
1215 of the number of bytes specified by the start byte.
1216 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1217 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1218 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1219 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001221- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001222 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1223 arises from the "Overriding __eq__ blocks inheritance ..." warning
1224 when turned into an exception: in this case the exception simply
1225 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001226
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001227- Issue #8748: Fix two issues with comparisons between complex and integer
1228 objects. (1) The comparison could incorrectly return True in some cases
1229 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1230 (2) The comparison raised an OverflowError for large integers, leading
1231 to unpredictable exceptions when combining integers and complex objects
1232 in sets or dicts.
1233
Mark Dickinson81336372010-05-30 12:12:25 +00001234- Issue #5211: Implicit coercion for the complex type is now completely
1235 removed. (Coercion for arithmetic operations was already removed in 2.7
1236 alpha 4, but coercion for rich comparisons was accidentally left in.)
1237
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001238- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1239 and error handler, instead of writing to the C stderr file in utf-8
1240
Georg Brandlfee0f442010-05-22 21:26:21 +00001241- Issue #7902: When using explicit relative import syntax, don't try implicit
1242 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00001243

1245 from another thread. Patch by Daniel Stutzbach.

Georg Brandlfee0f442010-05-22 21:26:21 +00001253- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
1254 of the interpreter to set sys.argv without also modifying sys.path. This
1255 helps fix `CVE-2008-5983

Georg Brandlfee0f442010-05-22 21:26:21 +00001371- Issue #1533: Fix inconsistency in range function argument processing: any
1372 non-float non-integer argument is now converted to an integer (if possible)
1373 using its __int__ method. Previously, only small arguments were treated this
1374 way; larger arguments (those whose __int__ was outside the range of a C long)

1427 trapped, the specification determines the order in which the signals should be
1428 handled. In many cases this order wasn't being followed, leading to the wrong

1602 changed.
1603
Georg Brandlfee0f442010-05-22 21:26:21 +00001604- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

Georg Brandlfee0f442010-05-22 21:26:21 +00001614- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1615 with a non-empty format string. This is an effort to future-proof user
1616 code. If a derived class does not currently implement __format__ but later
1617 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001618 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001619 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001669- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1670 InvalidOperation instead of returning False. (Comparisons involving a quiet
1671 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

Georg Brandlba83f822010-03-14 09:50:54 +00002056- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2057 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2058 returning NULL. The macro now returns a statically allocated empty string
2059 instead.

2069 strings,
2070 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2071 numeric strings corresponding to subnormal values,
2072 (3) a memory leak for some values large enough to cause overflow, and
2073 (4) a number of flaws that could lead to incorrectly rounded results.

2092
Georg Brandlba83f822010-03-14 09:50:54 +00002093- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00002104- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002105 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002106 Also, raise ValueError rather than TypeError when an unknown TIPC address
2107 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002111- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002112 file position when calling `truncate()`. It would previously change the file
2113 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002114 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2115
Georg Brandlba83f822010-03-14 09:50:54 +00002116- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2117 class used to represent files stored inside an archive. The new
2118 implementation is significantly faster and can be wrapped in a
2119 ``io.BufferedReader`` object for more speedups. It also solves an issue
2120 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2121 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002131- Issue #7748: Since unicode values are supported for some metadata options in
2132 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2133 encoded string for them. This ensures that the upload and register commands
2134 send the correct values to PyPI without any error.

2210
Georg Brandlba83f822010-03-14 09:50:54 +00002211- The ``__complex__()`` method is now looked up on the class of instances to
2212 make it consistent with other special methods.

2216
Mark Dickinson1b34d252010-01-01 17:27:30 +00002217- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002218 DeprecationWarning when passed a float argument where an integer was expected.
2219 These functions and methods now raise TypeError instead. The majority of the
2220 effects of this change are in the extension modules, but some core functions
2221 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2222 and many unicode/str methods.

2236 of integers: the result of a/b is now correctly rounded for ints a and b (at
2237 least on IEEE 754 platforms), and in particular does not depend on the
2238 internal representation of a long.

2246
Georg Brandlba83f822010-03-14 09:50:54 +00002247 These executables now work properly with the arch(1) command: ``arch -ppc
2248 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00002405- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2406 decimal string that's guaranteed to round back to x under correct rounding
2407 (with round-half-to-even rounding mode). Previously it gave a string based on
2408 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2409 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2410 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002412- Issue #7117: On almost all platforms: float-to-string and string-to-float
2413 conversions within Python are now correctly rounded. Places these conversions
2414 occur include: str for floats and complex numbers; the float and complex
2415 constructors; old-style and new-style numeric formatting; serialization and
2416 deserialization of floats and complex numbers using marshal, pickle and json;
2417 parsing of float and imaginary literals in Python code; Decimal-to-float
2418 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002419
Georg Brandlba83f822010-03-14 09:50:54 +00002420 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2421 providing correctly-rounded strtod and dtoa C functions. This code is
2422 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2423 the C compiler. There may be a small number of platforms on which correct
2424 operation of this code cannot be guaranteed, so the code is not used: notably,
2425 this applies to platforms where the C double format is not IEEE 754 binary64,
2426 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2427 and Python's configure script is unable to determine how to change the FPU
2428 precision. On these platforms conversions use the platform strtod and dtoa,
2429 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002431- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2432 uses the correctly-rounded string <-> float conversions described above (when
2433 available), and so produces correctly rounded results that will display nicely
2434 under the float repr. There are two related small changes: (1) round now
2435 accepts any class with an ``__index__()`` method for its second argument (but
2436 no longer accepts floats for the second argument), and (2) an excessively
2437 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2438 raises an exception.

2817 this code path is really executed because I cannot move to such directory on

2844 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Antoine Pitrou0668c622008-08-26 22:42:08 +00004247 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4248 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4249 when given a tuple of classes as second argument, were looking up
4250 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4251 type object.
4252
Neal Norwitz18aa3882008-08-24 05:04:52 +00004253- Fix crashes on memory allocation failure found with failmalloc.

4262 function 'stringlib_contains_obj'.
4263
Benjamin Peterson712ee922008-08-24 18:10:20 +00004264- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00004322 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4323 for catch_warnings() also led to an improvement in the raising of a
4324 DeprecationWarning related to warnings.warn_explicit().
4325

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004349- Issue #2975: When compiling several extension modules with Visual Studio 2008
4350 from the same python interpreter, some environment variables would grow
4351 without limit.
4352
Benjamin Peterson37346b22008-08-23 20:27:43 +00004353- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004390What's New in Python 2.6 beta 3?
4391================================
4392
Barry Warsaw07a4a382008-08-21 01:15:08 +00004393*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004394
4395Core and Builtins
4396-----------------
4397
Guido van Rossumf8402962008-08-20 15:01:50 +00004398- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4399 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4400 extensions do not automatically benefit from the class attribute
4401 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4402 to their tp_flags field if they care. This is a backwards
4403 compatibility feature; in 3.0, all types will use the cache by
4404 default.
4405
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004406- Keyword arguments can now follow starred arguments. (``f(a, *args,
4407 keyword=23)`` is now valid syntax.)
4408
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004409- ctypes function pointers that are COM methods have a boolean True
4410 value again.
4411
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004412- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4413 by denying s# to parse objects that have a releasebuffer procedure,
4414 and introducing s*.
4415
Georg Brandl1e13ea92008-08-11 09:07:59 +00004416- Issue #3537: Fix an assertion failure when an empty but presized dict
4417 object was stored in the freelist.
4418
Mark Dickinsonb6467572008-08-04 21:30:09 +00004419- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4420 ValueError consistently across platforms.
4421
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004422- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4423 (64bit Unix, for example), unichr() would truncate its argument and return
4424 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4425
Neal Norwitze7d8be82008-07-31 17:17:14 +00004426- Apply security patches from Apple.
4427
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004428- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4429 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4430
Antoine Pitrou92f82162008-07-25 22:22:08 +00004431- Issue #1819: function calls with several named parameters are now on
4432 average 35% faster (as measured by pybench).
4433
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004434- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4435 the python debugger steps into a class statement: the free variables (local
4436 variables defined in an outer scope) would be deleted from the outer scope.
4437
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004438- Issue #2620: Overflow checking when allocating or reallocating memory
4439 was not always being done properly in some python types and extension
4440 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4441 all been updated to perform better checks and places in the code that
4442 would previously leak memory on the error path when such an allocation
4443 failed have been fixed.

4446-------
4447
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004448- Issue #3612: Added some missing basic types in ctypes.wintypes.
4449
Benjamin Petersone977ad42008-08-20 01:42:01 +00004450- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4451 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4452
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004453- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4454 version reported by these tools does not necessarily follow the python
4455 version numbering scheme, so the module is less strict when parsing it.
4456
Nick Coghlanf70385a2008-08-18 12:42:46 +00004457- Issue #2235: Added Py3k warnings for types which will become unhashable
4458 under the stricter __hash__ inheritance rules in 3.0. Several types
4459 which did not meet the rules for hash invariants and were already
4460 unhashable in 3.0 have now been explicitly flagged as unhashable in
4461 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4462 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4463
Brett Cannon88f801d2008-08-18 00:46:22 +00004464- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4465 imported into the module but exposed as part of the module's API.
4466
Brett Cannon7b96f072008-08-18 00:41:11 +00004467- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4468
Brett Cannon46225e72008-08-18 00:36:52 +00004469- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004471- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4472
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004473- Issue #3575: Incremental decoder's decode function now takes bytearray
4474 by using 's*' instead of 't#'.
4475
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004476- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004477 fails unicode conversion on 2nd parameter. (windows only)
4478
Georg Brandl222e2082010-08-01 22:27:39 +00004479- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004480 in a redirect.
4481
Brett Cannonabe423e2008-08-16 21:47:07 +00004482- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004483 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004484
Facundo Batistaeb90b782008-08-16 14:44:07 +00004485- Issue #2776: fixed small issue when handling an URL with double slash
4486 after a 302 response in the case of not going through a proxy.
4487
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004488- Issue #2676: in the email package, content-type parsing was hanging on
4489 pathological input because of quadratic or exponential behaviour of a
4490 regular expression.
4491
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004492- Issue #3476: binary buffered reading through the new "io" library is now
4493 thread-safe.
4494
Brett Cannonbf3157b2008-08-14 05:00:03 +00004495- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4496 since mimetools itself is deprecated. Because modules are cached, all
4497 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4498
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004499- Issue #3134: shutil referenced undefined WindowsError symbol.
4500
Robert Schuppenies14646332008-08-10 11:01:53 +00004501- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4502 menu entries were not deleted.
4503
Brett Cannon83e81842008-08-09 23:30:55 +00004504- Copied the implementation of reduce() to _functools.reduce() to have a
4505 version that did not raise a DeprecationWarning under -3.
4506
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004507- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4508 a MemoryError rather than silently stop the iteration.
4509
Guido van Rossum59ce9012008-08-09 14:55:34 +00004510- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4511 to _sre.compile() will now be rejected. This should not affect anybody
4512 since the re.compile() function never generates invalid re-bytecode.
4513
Skip Montanaroa032bf42008-08-08 22:52:51 +00004514- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4515 upon first access it can be automatically initialized from the csv file if
4516 it wasn't initialized during instantiation.
4517
Brett Cannon3aa2a492008-08-06 22:28:09 +00004518- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4519 the reload() built-in has been removed.
4520
Brett Cannon7e30b672008-08-04 21:52:25 +00004521- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004522 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4525 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4526 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4527 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004528

4590-----------------
4591
Georg Brandl3e483f62008-07-16 22:57:41 +00004592- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4593 its methods now allow for items objects that can be converted to
4594 an integer using operator.index().
4595
Mark Dickinson64b7e502008-07-16 09:40:03 +00004596- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4597 produced a ValueError instead of giving the correct float.
4598
Eric Smitha5fa5a22008-07-16 00:11:49 +00004599- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4600 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4601
Mark Dickinson7103aa42008-07-15 19:08:33 +00004602- Issue #3008: the float type has a new instance method 'float.hex'
4603 and a new class method 'float.fromhex' to convert floating-point
4604 numbers to and from hexadecimal strings, respectively.
4605
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004606- Issue #2235: __hash__ is once again inherited by default. To allow
4607 collections.Hashable to remain meaningful in the presence of the
4608 default hash implementation (object.__hash__), it is now possible
4609 to explicit block inheritance of hash by setting __hash__=None at
4610 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4611 level.
4612
Nick Coghlanb028f502008-07-13 14:52:36 +00004613- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4614 the parent module cannot be found while performing an absolute import.
4615 This means that an incorrectly defined __package__ attribute will
4616 now only prevent relative imports in that module rather than causing
4617 all imports from that module to fail.
4618
Nick Coghlan14ff9942008-07-08 14:21:42 +00004619- Issue #2517: Allow unicode messages in Exceptions again by correctly

4629 another thread's dictionary.
4630
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004631- Issue #3004: Minor change to slice.indices(): the start and stop
4632 arguments are now treated identically, making the behaviour easier
4633 to describe and understand. For example, slice(None, -10,
4634 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4635 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4636 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00004638- Issue #3219: Calling a function with repeated keyword arguments,
4639 f(a=2, a=23), would not cause a syntax error. This was a regression
4640 from 2.4 caused by the switch to the new compiler.

4679 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004680 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004681 content-length. The problem had been corrected in the 2.4 branch, but never
4682 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004697- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5107
Georg Brandl74a1dea2008-05-28 11:21:39 +00005108- Add ``PyType_Modified()`` as a public API to clear the type cache.
5109
5110- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00005111
5112- The PyString functions have been renamed to PyBytes. A batch of
5113 defines were added so that the linker still sees the original
5114 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005152- Issue #1631171: Re-implement the 'warnings' module in C (the
5153 original Python code has been kept as backup). This will allow for
5154 using the 'warning's machinery in such places as the parser where
5155 use of pure Python code is not possible. Both the ``showarning()``
5156 and ``formatwarning()`` gain an optional 'line' argument which is
5157 not called by default for backwards-compatibility reasons. Setting
5158 ``warnings.showwarning()`` to an implementation that lacks support
5159 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005201- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005202 extension modules between 32 and 64 bit platforms. See the distutls

5206 threads at once without fear of crashing the Python interpreter. If
5207 file.close() is called while an object is in use by another thread
5208 an IOError exception will be raised and the file will not be closed.
5209
Thomas Hellerf7906482008-04-04 19:43:25 +00005210- The bundled libffi copy is now in sync with the recently released

5215 so the controlled environment will more closely mirror the typical
5216 script environment. This supports setup.py scripts that refer to
5217 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005222- Issue #2550: The approach used by client/server code for obtaining
5223 ports to listen on in network-oriented tests has been refined in an
5224 effort to facilitate running multiple instances of the entire
5225 regression test suite in parallel without issue.
5226 test_support.bind_port() has been fixed such that it will always
5227 return a unique port -- which wasn't always the case with the
5228 previous implementation, especially if socket options had been set
5229 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5230 new implementation of bind_port() will actually raise an exception
5231 if it is passed an AF_INET/SOCK_STREAM socket with either the
5232 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5233 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5234 the socket it's been passed. This currently only applies to
5235 Windows. This option prevents any other sockets from binding to the
5236 host/port we've bound to, thus removing the possibility of the
5237 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5238 when a second SOCK_STREAM socket binds and accepts to a host/port
5239 that's already been bound by another socket. The optional preferred
5240 port parameter to bind_port() has been removed. Under no
5241 circumstances should tests be hard coding ports!
5242
5243 test_support.find_unused_port() has also been introduced, which will
5244 pass a temporary socket object to bind_port() in order to obtain an
5245 unused port. The temporary socket object is then closed and
5246 deleted, and the port is returned. This method should only be used
5247 for obtaining an unused port in order to pass to an external program
5248 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5249 a parameter to a server-oriented class that doesn't give you direct
5250 access to the underlying socket used.
5251
5252 Finally, test_support.HOST has been introduced, which should be used
5253 for the host argument of any relevant socket calls (i.e. bind and
5254 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005255
5256 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005257 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005258 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5259 test_asynchat and test_socket_ssl.
5260
Georg Brandl3ee81df2008-05-17 18:14:43 +00005261 It is now possible for multiple instances of the regression test
5262 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005541- Added the future_builtins module, which contains hex() and oct().
5542 These are the PEP 3127 version of these functions, designed to be
5543 compatible with the hex() and oct() builtins from Python 3.0. They
5544 differ slightly in their output formats from the existing, unchanged
5545 Python 2.6 builtins. The expected usage of the future_builtins
5546 module is:
5547 from future_builtins import hex, oct
5548
Eric Smith7ef40bf2008-02-20 23:34:22 +00005549- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5550 exponents for exponents with absolute value < 100. Follows C99
5551 standard. This is a change on Windows, which would use 3 digits.
5552 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5553 so that any alterations it does to the resulting string will be
5554 available in stringlib/formatter.h (for float.__format__).
5555
Eric Smith5a3c1352008-02-19 13:21:56 +00005556- Implemented PEP 3101, Advanced String Formatting. This adds a new
5557 builtin format(); a format() method for str and unicode; a
5558 __format__() method to object, str, unicode, int, long, float, and
5559 datetime; the class string.Formatter; and the C API
5560 PyObject_Format().
5561
Georg Brandl3ee81df2008-05-17 18:14:43 +00005562- Fixed several potential crashes, all caused by specially crafted
5563 __del__ methods exploiting objects in temporarily inconsistent
5564 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005565
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005566- Issue #2115: Important speedup in setting __slot__ attributes. Also

5575 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005576
Georg Brandl3ee81df2008-05-17 18:14:43 +00005577- Issue #2045: Fix an infinite recursion triggered when printing a
5578 subclass of collections.defaultdict, if its default_factory is set
5579 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005580
Christian Heimesf75dbef2008-02-08 00:11:31 +00005581- Fixed a minor memory leak in dictobject.c. The content of the free

5590
Georg Brandl3ee81df2008-05-17 18:14:43 +00005591- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5592 calls. Python expected the return type int but the fork familie
5593 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005594

Georg Brandl3ee81df2008-05-17 18:14:43 +00005607- Patch #1473257: generator objects gain a gi_code attribute. This is
5608 the same object as the func_code attribute of the function that
5609 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005610
Georg Brandl3ee81df2008-05-17 18:14:43 +00005611- Issue #1920: "while 0" statements were completely removed by the
5612 compiler, even in the presence of an "else" clause, which is

5614 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00005616- A few crashers fixed: weakref_in_del.py (issue #1377858);
5617 loosing_dict_ref.py (issue #1303614, test67.py);
5618 borrowed_ref_[34].py (not in tracker).
5619
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005620- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005621 suppressed while an extension is loaded by calling SetErrorMode in
5622 dynload_win.c. The error is still reported properly.
5623
Georg Brandl3ee81df2008-05-17 18:14:43 +00005624- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005625 several extension methods and modules do not work without unicode
5626 support.
5627
Georg Brandl26543b12008-01-21 18:36:51 +00005628- Issue #1882: when compiling code from a string, encoding cookies in the
5629 second line of code were not always recognized correctly.
5630
Georg Brandl14404b62008-01-19 19:27:05 +00005631- Issue #1679: "0x" was taken as a valid integer literal.
5632
Georg Brandl6caad7d2008-01-26 14:19:22 +00005633- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005634 added.
5635
Christian Heimesc94e2b52008-01-14 04:13:37 +00005636- sys.float_info / PyFloat_GetInfo: The floating point information
5637 object was converted from a dict to a specialized structseq object.
5638
Georg Brandl3ee81df2008-05-17 18:14:43 +00005639- Patch #1816: Added sys.flags structseq. It exposes the status of
5640 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005641
Georg Brandl3ee81df2008-05-17 18:14:43 +00005642- Objects/structseq.c: Implemented new structseq representation. The
5643 patch makes structseqs (e.g. the return value of os.stat) more
5644 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005645
Georg Brandl3ee81df2008-05-17 18:14:43 +00005646- Patch #1700288: added a type attribute cache that caches method
5647 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005648
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005649- Bug #1776: __import__() no longer accepts filenames on any platform.
5650 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005651
Georg Brandlaed6c662008-01-07 17:25:53 +00005652- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5653
Georg Brandl3ee81df2008-05-17 18:14:43 +00005654- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5655 envvar and sys.dont_write_bytecode attribute. All these can be set
5656 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005657
Georg Brandl3ee81df2008-05-17 18:14:43 +00005658- Improve some exception messages when Windows fails to load an
5659 extension module. Now we get for example '%1 is not a valid Win32
5660 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005661

Georg Brandl3ee81df2008-05-17 18:14:43 +00005664- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5665 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005666
Christian Heimes0a8143f2007-12-18 23:22:54 +00005667- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005668 and INF. float("nan"), float("inf") and float("-inf") now work on
5669 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005670
Georg Brandl3ee81df2008-05-17 18:14:43 +00005671- Compiler now generates simpler and faster code for dictionary
5672 literals. The oparg for BUILD_MAP now indicates an estimated
5673 dictionary size. There is a new opcode, STORE_MAP, for adding
5674 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005703- Patch #1739468: Directories and zipfiles containing a __main__.py
5704 file can now be directly executed by passing their name to the
5705 interpreter. The directory/zipfile is automatically inserted as the
5706 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005707
Georg Brandl3ee81df2008-05-17 18:14:43 +00005708- Issue #1265: Fix a problem with sys.settrace, if the tracing
5709 function uses a generator expression when at the same time the
5710 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005711
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005712- sets and frozensets now have an isdisjoint() method.
5713
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005714- optimize the performance of builtin.sum().
5715
Neal Norwitz44f326e2007-10-05 05:29:17 +00005716- Fix warnings found by the new version of the Coverity checker.
5717
Georg Brandl21e99f42010-03-07 15:23:59 +00005718- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005719 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5720 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005721
Georg Brandl3ee81df2008-05-17 18:14:43 +00005722- Issue #1686386: Tuple's tp_repr did not take into account the
5723 possibility of having a self-referential tuple, which is possible
5724 from C code. Nor did object's tp_str consider that a type's tp_str
5725 could do something that could lead to an inifinite recursion.
5726 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5727 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005728
Georg Brandl3ee81df2008-05-17 18:14:43 +00005729- Issue #1164: It was possible to trigger deadlock when using the
5730 'print' statement to write to a file since the GIL was not released
5731 as needed. Now PyObject_Print() does the right thing along with
5732 various tp_print implementations of the built-in types and those in
5733 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005734
Georg Brandl3ee81df2008-05-17 18:14:43 +00005735- Issue #1147: Exceptions were directly allowing string exceptions in
5736 their throw() method even though string exceptions no longer
5737 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005738
Georg Brandl3ee81df2008-05-17 18:14:43 +00005739- Issue #1096: Prevent a segfault from getting the repr of a very
5740 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005741
Brett Cannon1e534b52007-09-07 04:18:30 +00005742- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005743 PyObject_Call() never calling back out to Python code to trigger
5744 recursion depth updates/checks. Required the creation of a static
5745 RuntimeError instance in case normalizing an exception put the
5746 recursion check value past its limit. Fixes crashers
5747 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005748
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005762- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005763 __*__ attributes. (Some already existed, e.g., __doc__ and
5764 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005765
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005766- Add -3 option to the interpreter to warn about features that are
5767 deprecated and will be changed/removed in Python 3.0.
5768
Georg Brandl2134e752007-05-21 20:34:16 +00005769- Patch #1686487: you can now pass any mapping after '**' in function
5770 calls.
5771
Collin Winter62903052007-05-18 23:11:24 +00005772- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773 "except E as target:". This is to provide forwards compatibility
5774 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005775
Brett Cannon229cee22007-05-05 01:34:02 +00005776- Deprecate BaseException.message as per PEP 352.
5777
Georg Brandl3ee81df2008-05-17 18:14:43 +00005778- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005779 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005780
Vinay Sajip8549ce32007-05-06 17:53:37 +00005781- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005782 setting a plain string, ie don't expand to single letter identifiers.
5783
Raymond Hettinger13936692007-04-11 18:40:58 +00005784- Request #1191699: Slices can now be pickled.
5785
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005786- Request #1193128: str.translate() now allows a None argument for
5787 translations that only remove characters without re-mapping the
5788 remaining characters.
5789
Georg Brandl5cb76c12007-03-21 09:00:39 +00005790- Patch #1682205: a TypeError while unpacking an iterable is no longer
5791 masked by a generic one with the message "unpack non-sequence".
5792
Neal Norwitzaa754b72007-03-21 06:39:48 +00005793- Remove unused file Python/fmod.c.
5794
Guido van Rossum143b5642007-03-23 04:58:42 +00005795- Bug #1683368: The object.__init__() and object.__new__() methods are
5796 now stricter in rejecting excess arguments. The only time when
5797 either allows excess arguments is when it is not overridden and the
5798 other one is. For backwards compatibility, when both are
5799 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005800 warning later). Also, type.__init__() insists on the same signature
5801 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005802
Georg Brandl3ee81df2008-05-17 18:14:43 +00005803- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5804 object to complex using its __complex__() method before falling back
5805 to the __float__() method. Therefore, the functions in the cmath
5806 module now can operate on objects that define a __complex__()
5807 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005808
Georg Brandl3ee81df2008-05-17 18:14:43 +00005809- Patch #1623563: allow __class__ assignment for classes with
5810 __slots__. The old and the new class are still required to have the
5811 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005812
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00005816- Patch #1462488: Python no longer segfaults when
5817 ``object.__reduce_ex__()`` is called with an object that is faking
5818 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005819
Georg Brandl3ee81df2008-05-17 18:14:43 +00005820- Patch #1680015: Don't modify __slots__ tuple if it contains an

5824
Georg Brandl7b9c5552007-03-12 14:30:05 +00005825- Bug #1678647: write a newline after printing an exception in any
5826 case, even when converting the value to a string failed.
5827
Georg Brandl871f1bc2007-03-12 13:17:36 +00005828- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005829 its argument, if it exists. If not, it will work like before. This
5830 allows customizing the output of dir() in the presence of a
5831 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005832
Collin Winter276887b2007-03-12 16:11:39 +00005833- Patch #922167: Python no longer segfaults when faced with infinitely
5834 self-recursive reload() calls (as reported by bug #742342).
5835
Georg Brandl3ee81df2008-05-17 18:14:43 +00005836- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005839- Patch #1491866: change the complex() constructor to allow
5840 parthensized forms. This means complex(repr(x)) now works instead of
5841 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005842
Georg Brandlaa2321b2007-03-07 00:40:28 +00005843- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005844 makes the filenames the warning module prints much more sensible
5845 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005846
Georg Brandl49aafc92007-03-07 00:34:46 +00005847- Variant of patch #697613: don't exit the interpreter on a SystemExit
5848 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005849 variable is given, but break into the interactive interpreter just
5850 like on other exceptions or normal program exit.

6352 ".cpp" too.
6353
Facundo Batistad918a652007-04-24 13:54:38 +00006354- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006355 the client's request was successfully received, understood, and
6356 accepted. Now in these cases no error is raised in urllib (issue
6357 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006365- Added a timeout parameter to the constructor of other protocols
6366 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6367 work started with create_connection() and timeout in httplib, and
6368 closes patch #723312.
6369
Vinay Sajip8549ce32007-05-06 17:53:37 +00006370- Patch #1676823: Added create_connection() to socket.py, which may be
6371 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00006373
Martin v. Löwis0af33882007-03-23 13:27:15 +00006374- Bug #978833: Revert r50844, as it broke _socketobject.dup.

6394
Georg Brandlf66b6032007-03-14 08:27:52 +00006395- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006396 AttributeError instead of an IOError when the server's response
6397 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006398
Georg Brandl3ee81df2008-05-17 18:14:43 +00006399- Patch #957650: "%var%" environment variable references are now
6400 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00006402
Georg Brandl3ee81df2008-05-17 18:14:43 +00006403- Patch #1429539: pdb now correctly initializes the __main__ module
6404 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006405 correctly now.
6406
Georg Brandlbad6f192007-03-13 21:32:56 +00006407- The nonobvious commands.getstatus() function is now deprecated.

6413
Georg Brandl3ee81df2008-05-17 18:14:43 +00006414- Patch #1530482: add pydoc.render_doc() which returns the
6415 documentation for a thing instead of paging it to stdout, which
6416 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00006417
Georg Brandl3ee81df2008-05-17 18:14:43 +00006418- Patch #1533909: the timeit module now accepts callables in addition

6425 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00006427- Patch #1581073: add a flag to textwrap that prevents the dropping of
6428 whitespace while wrapping.
6429
Georg Brandl92a6bae2007-03-13 17:43:32 +00006430- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006431 are set for invalid interpolation sequences that would lead to
6432 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00006433

6449 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00006467

6475 returned string up to the first NUL character.

6486
Georg Brandl3ee81df2008-05-17 18:14:43 +00006487- unittest now verifies more of its assumptions. In particular,
6488 TestCase and TestSuite subclasses (not instances) are no longer
6489 accepted in TestSuite.addTest(). This should cause no
6490 incompatibility since it never made sense with ordinary subclasses
6491 -- the failure just occurred later, with a more cumbersome
6492 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00006493

6501 given a unicode argument and os.listdir() returns unicode filenames.
6502
Georg Brandl3ee81df2008-05-17 18:14:43 +00006503- Patch #1673619: setup.py identifies extension modules it doesn't

6505 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006881 time so that opening a database previously created with the DB_DUP
6882 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6883 opens. Specifically: dictionary assignment to a DB object will
6884 replace all values for a given key when the database allows
6885 duplicate values. DB users should use DB.put(k, v) when they want
6886 to store duplicates; not DB[k] = v.

6893 characters with ASCII value less than 32. Also, it correctly quotes
6894 dots only if they occur on a single line, as opposed to the previous
6895 behavior of quoting dots if they are the second character of any
6896 line.
