Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000091- Issue #7419: setlocale() could crash the interpreter on Windows when called
92 with invalid values.
93
Eric Smithc4ab8332009-11-29 17:40:57 +000094- Issue #3382: 'F' formatting for float and complex now convert the
95 result to upper case. This only affects 'inf' and 'nan', since 'f'
96 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000097
Mark Dickinson9dd5e162009-11-23 20:54:09 +000098- Remove switch from "%f" formatting to "%g" formatting for floats
99 larger than 1e50 in absolute value.
100
Mark Dickinson18cfada2009-11-23 18:46:41 +0000101- Remove restrictions on precision when formatting floats. E.g.,
102 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
103 requested 120 significant digits instead.
104
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000105- Add Py3k warnings for parameter names in parenthesis.
106
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000107- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000108
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000109- Issue #7085: Fix crash when importing some extensions in a thread
110 on MacOSX 10.6.
111
Mark Dickinsonb678de82009-11-19 18:41:49 +0000112- Issue #7117: repr(x) for a float x returns a result based on the
113 shortest decimal string that's guaranteed to round back to x under
114 correct rounding (with round-half-to-even rounding mode).
115 Previously it gave a string based on rounding x to 17 decimal digits.
116 repr(x) for a complex number behaves similarly. On platforms where
117 the correctly-rounded strtod and dtoa code is not supported (see below),
118 repr is unchanged.
119
120- Issue #7117: On almost all platforms: float-to-string and
121 string-to-float conversions within Python are now correctly rounded.
122 Places these conversions occur include: str for floats and complex
123 numbers; the float and complex constructors; old-style and new-style
124 numeric formatting; serialization and deserialization of floats and
125 complex numbers using marshal, pickle and json; parsing of float and
126 imaginary literals in Python code; Decimal-to-float conversion.
127
128 The conversions use a Python-adapted version of David Gay's
129 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
130 functions. This code is supported on Windows, and on Unix-like
131 platforms using gcc, icc or suncc as the C compiler. There may be a
132 small number of platforms on which correct operation of this code
133 cannot be guaranteed, so the code is not used: notably, this applies
134 to platforms where the C double format is not IEEE 754 binary64, and
135 to platforms on x86 hardware where the x87 FPU is set to 64-bit
136 precision and Python's configure script is unable to determine how
137 to change the FPU precision. On these platforms conversions use the
138 platform strtod and dtoa, as before.
139
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000140- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000141 now uses the correctly-rounded string <-> float conversions
142 described above (when available), and so produces correctly rounded
143 results that will display nicely under the float repr. There are
144 two related small changes: (1) round now accepts any class with an
145 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000146 floats for the second argument), and (2) an excessively large second
147 integer argument (e.g., round(1.234, 10**100)) no longer raises an
148 exception.
149
Philip Jenveyfab8be22009-11-17 02:42:26 +0000150- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
151
Benjamin Petersone36199b2009-11-12 23:39:44 +0000152- Fix several issues with compile(). The input can now contain Windows and Mac
153 newlines and is no longer required to end in a newline.
154
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000155- Remove length limitation when constructing a complex number from a
156 unicode string.
157
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000158- Issue #7244: itertools.izip_longest() no longer ignores exceptions
159 raised during the formation of an output tuple.
160

166
Eric Smithc12781a2009-10-19 14:38:14 +0000167- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

196 of producing internally inconsistent Python longs.
197
Philip Jenveydbf3b252009-09-29 04:32:44 +0000198- Issue #6990: Fix threading.local subclasses leaving old state around

292 rejected; (2) parsing of strings representing infinities and nans
293 was locale aware; and (3) the interpretation of fromhex('-nan')
294 didn't match that of float('-nan').
295
Eric Smitha985a3a2009-05-05 18:26:08 +0000296- Issue #5920: For float.__format__, change the behavior with the
297 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
298 to be like 'g' but with at least one decimal point and with a
299 default precision of 12. Previously, the behavior the same but with
300 a default precision of 6. This more closely matches str(), and
301 reduces surprises when adding alignment flags to the empty
302 presentation type. This also affects the new complex.__format__ in
303 the same way.
304
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000305- Issue #5890: in subclasses of 'property' the __doc__ attribute was

366
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000367- Issue #4688: Add a heuristic so that tuples and dicts containing only
368 untrackable objects are not tracked by the garbage collector. This can
369 reduce the size of collections and therefore the garbage collection overhead
370 on long-running programs, depending on their particular use of datatypes.

375
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000376- Issue #4258: Make it possible to use base 2**30 instead of base
377 2**15 for the internal representation of integers, for performance
378 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
379 --enable-big-digits option to configure, which overrides the
380 default. Add sys.long_info structseq to provide information about
381 the internal format.
382
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000383- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

385
Mark Dickinson6b265f12009-03-18 16:07:26 +0000386- Issue #4474: PyUnicode_FromWideChar now converts characters outside
387 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

392
Brett Cannon6c4cff02009-03-11 04:51:06 +0000393- Issue #3652: Make the 'line' argument for warnings.showwarning() a

398 float arguments.
399
Raymond Hettinger08259e82009-02-18 23:10:19 +0000400- Running Python with the -3 option now also warns about classic division
401 for ints and longs.
402
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000403- Issue #5260: Long integers now consume less memory: average
404 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
405 on a 64-bit system.
406
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000407- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

414
Georg Brandl29c6a282009-04-05 20:23:13 +0000415- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000416 were suppressing all exceptions. These include list(), filter(), map(),
417 zip(), and bytearray().
418
Benjamin Peterson596d3062009-01-19 15:42:23 +0000419- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
420 functions.
421
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000422- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

426
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000427- Issue #4935: The overflow checking code in the expandtabs() method common
428 to str, bytes and bytearray could be optimized away by the compiler, letting
429 the interpreter segfault instead of raising an error.
430
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000431- Issue #3720: Fix a crash when an iterator modifies its class and removes its

437
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000438- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
439 collecting the oldest generation) so that allocating lots of objects without
440 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000441 Martin von Löwis at

445
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000446- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
447 an existing .py counterpart, override the co_filename attributes of all
448 code objects if the original filename is obsolete (which can happen if the
449 file has been renamed, moved, or if it is accessed through different paths).
450 Patch by Ziga Seilnacht and Jean-Paul Calderone.

459
Nick Coghlan180e4002008-12-30 01:18:48 +0000460- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
461 where the tp_hash and tp_dict slots are both NULL.
462
Benjamin Peterson7af65562008-12-29 17:56:58 +0000463- Issue #4764: With io.open, IOError.filename is set when trying to open a

470 bytearray.translate(). It was always allowed for bytes.translate().
471
Skip Montanarof205c132008-12-23 03:30:15 +0000472- Added test case to ensure attempts to read from a file opened for writing
473 fail.
474
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000475- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

488 exceptions.
489
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000490- Issue #4445: Replace "sizeof(PyStringObject)" with
491 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
492 str instances. On a typical machine this saves 3 bytes of memory
493 (on average) per string allocation.
494
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000495- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
496 interpreter to abort ("Fatal Python error: Could not reset the stack!")
497 instead of throwing a MemoryError.
498
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000499- Issue #3689: The list reversed iterator now supports __length_hint__

501
Benjamin Petersonc078f922008-11-21 22:27:24 +0000502- Issue #4367: Python would segfault during compiling when the unicodedata

504
Vinay Sajip213faca2008-12-03 23:22:58 +0000505- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000506 method on file objects with closefd=False. The file descriptor is still
507 kept open but the file object behaves like a closed file. The ``FileIO``
508 object also got a new readonly attribute ``closefd``.
509
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000510- Issue #4348: Some bytearray methods returned that didn't cause any change to
511 the bytearray, returned the same bytearray instead of a copy.
512
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000513- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

521
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000522- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``

524
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000525- Issue #4209: Enabling unicode_literals and the print_function in the same
526 __future__ import didn't work.
527
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000528- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000529 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000531- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
532 returned a path longer than MAX_PATH. (But It's doubtful this code path is
533 really executed because I cannot move to such directory on win2k)
534
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000535- Issue #4069: When set.remove(element) is used with a set element, the element
536 is temporarily replaced with an equivalent frozenset. But the eventual
537 KeyError would always report the empty frozenset([]) as the missing key. Now
538 it correctly refers to the initial element.
539

556 returned them on 64bit platforms.
557
Walter Dörwalded960ac2009-05-03 22:36:33 +0000558- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
559 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
560 step. This avoids problems with counting UTF-8 bytes that ignores the effect
561 of using the replace error handler in PyUnicode_DecodeUTF8().
562
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000563- Issue #3739: The unicode-internal encoder now reports the number of characters
564 consumed like any other encoder (instead of the number of bytes).
565
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000566- Issue #2422: When compiled with the ``--with-valgrind`` option, the
567 pymalloc allocator will be automatically disabled when running under
568 Valgrind. This gives improved memory leak detection when running
569 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou59c44f32009-10-30 17:07:08 +00001805- Issue #7222: Make thread "reaping" more reliable so that reference
1806 leak-chasing test runs give sensible results. The previous method of
1807 reaping threads could return successfully while some Thread objects were
1808 still referenced. This also introduces a new private function:

1827 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

1835 it easy to import both normal and optimised versions of modules.
1836 test_heapq and test_warnings have been adjusted to use it, tests for
1837 other modules with both C and Python implementations in the stdlib
1838 can be adjusted to use it over time.

Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001847 that should cause a test to be skipped are now done using import_module

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001951- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1952 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1953 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1954 ``printf`` function, whereas PyString_FromFormat has an independent
1955 implementation and uses "%zd" on all platforms for size_t values.
1956 This makes a difference on win64, where ``printf`` needs "%Id" to display

1963 object; previously an int would be returned for small values. the __long__
1964 method is allowed to return either an int or a long, but the behaviour of

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002120What's New in Python 2.6 beta 3?
2121================================
2122
Barry Warsaw07a4a382008-08-21 01:15:08 +00002123*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002124
2125Core and Builtins
2126-----------------
2127
Guido van Rossumf8402962008-08-20 15:01:50 +00002128- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2129 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2130 extensions do not automatically benefit from the class attribute
2131 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2132 to their tp_flags field if they care. This is a backwards
2133 compatibility feature; in 3.0, all types will use the cache by
2134 default.
2135
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002136- Keyword arguments can now follow starred arguments. (``f(a, *args,
2137 keyword=23)`` is now valid syntax.)
2138
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002139- ctypes function pointers that are COM methods have a boolean True
2140 value again.
2141
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002142- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2143 by denying s# to parse objects that have a releasebuffer procedure,
2144 and introducing s*.
2145
Georg Brandl1e13ea92008-08-11 09:07:59 +00002146- Issue #3537: Fix an assertion failure when an empty but presized dict
2147 object was stored in the freelist.
2148
Mark Dickinsonb6467572008-08-04 21:30:09 +00002149- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2150 ValueError consistently across platforms.
2151
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002152- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2153 (64bit Unix, for example), unichr() would truncate its argument and return
2154 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2155
Neal Norwitze7d8be82008-07-31 17:17:14 +00002156- Apply security patches from Apple.
2157
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002158- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2159 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2160
Antoine Pitrou92f82162008-07-25 22:22:08 +00002161- Issue #1819: function calls with several named parameters are now on
2162 average 35% faster (as measured by pybench).
2163
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002164- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2165 the python debugger steps into a class statement: the free variables (local
2166 variables defined in an outer scope) would be deleted from the outer scope.
2167
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002168- Issue #2620: Overflow checking when allocating or reallocating memory
2169 was not always being done properly in some python types and extension
2170 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2171 all been updated to perform better checks and places in the code that
2172 would previously leak memory on the error path when such an allocation
2173 failed have been fixed.

2179
Benjamin Petersone977ad42008-08-20 01:42:01 +00002180- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2181 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2182
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002183- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2184 version reported by these tools does not necessarily follow the python
2185 version numbering scheme, so the module is less strict when parsing it.
2186
Nick Coghlanf70385a2008-08-18 12:42:46 +00002187- Issue #2235: Added Py3k warnings for types which will become unhashable
2188 under the stricter __hash__ inheritance rules in 3.0. Several types
2189 which did not meet the rules for hash invariants and were already
2190 unhashable in 3.0 have now been explicitly flagged as unhashable in
2191 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2192 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2193
Brett Cannon88f801d2008-08-18 00:46:22 +00002194- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2195 imported into the module but exposed as part of the module's API.
2196
Brett Cannon7b96f072008-08-18 00:41:11 +00002197- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2198
Brett Cannon46225e72008-08-18 00:36:52 +00002199- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002201- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2202
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002203- Issue #3575: Incremental decoder's decode function now takes bytearray
2204 by using 's*' instead of 't#'.
2205
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002206- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002207 fails unicode conversion on 2nd parameter. (windows only)
2208
Facundo Batista94f243a2008-08-17 03:38:39 +00002209- Issue 2464. urllib2 now supports a malformation in the URL received
2210 in a redirect.
2211
Brett Cannonabe423e2008-08-16 21:47:07 +00002212- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002213 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002214
Facundo Batistaeb90b782008-08-16 14:44:07 +00002215- Issue #2776: fixed small issue when handling an URL with double slash
2216 after a 302 response in the case of not going through a proxy.
2217
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002218- Issue #2676: in the email package, content-type parsing was hanging on
2219 pathological input because of quadratic or exponential behaviour of a
2220 regular expression.
2221
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002222- Issue #3476: binary buffered reading through the new "io" library is now
2223 thread-safe.
2224
Brett Cannonbf3157b2008-08-14 05:00:03 +00002225- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2226 since mimetools itself is deprecated. Because modules are cached, all
2227 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2228
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002229- Issue #3134: shutil referenced undefined WindowsError symbol.
2230
Robert Schuppenies14646332008-08-10 11:01:53 +00002231- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2232 menu entries were not deleted.
2233
Brett Cannon83e81842008-08-09 23:30:55 +00002234- Copied the implementation of reduce() to _functools.reduce() to have a
2235 version that did not raise a DeprecationWarning under -3.
2236
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002237- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2238 a MemoryError rather than silently stop the iteration.
2239
Guido van Rossum59ce9012008-08-09 14:55:34 +00002240- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2241 to _sre.compile() will now be rejected. This should not affect anybody
2242 since the re.compile() function never generates invalid re-bytecode.
2243
Skip Montanaroa032bf42008-08-08 22:52:51 +00002244- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2245 upon first access it can be automatically initialized from the csv file if
2246 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00002248- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2249 the reload() built-in has been removed.
2250
Brett Cannon7e30b672008-08-04 21:52:25 +00002251- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00002263 asking for a specific length. This problem only affected files opened
2264 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002265

2307
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002308- Issue #643841: The language reference now provides more detailed

2316
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002317*Release date: 17-Jul-2008*

2320-----------------
2321
Georg Brandl3e483f62008-07-16 22:57:41 +00002322- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2323 its methods now allow for items objects that can be converted to
2324 an integer using operator.index().
2325
Mark Dickinson64b7e502008-07-16 09:40:03 +00002326- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2327 produced a ValueError instead of giving the correct float.
2328
Eric Smitha5fa5a22008-07-16 00:11:49 +00002329- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2330 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2331
Mark Dickinson7103aa42008-07-15 19:08:33 +00002332- Issue #3008: the float type has a new instance method 'float.hex'
2333 and a new class method 'float.fromhex' to convert floating-point
2334 numbers to and from hexadecimal strings, respectively.
2335
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002336- Issue #2235: __hash__ is once again inherited by default. To allow
2337 collections.Hashable to remain meaningful in the presence of the
2338 default hash implementation (object.__hash__), it is now possible
2339 to explicit block inheritance of hash by setting __hash__=None at
2340 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2341 level.
2342
Nick Coghlanb028f502008-07-13 14:52:36 +00002343- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2344 the parent module cannot be found while performing an absolute import.
2345 This means that an incorrectly defined __package__ attribute will
2346 now only prevent relative imports in that module rather than causing
2347 all imports from that module to fail.
2348
Nick Coghlan14ff9942008-07-08 14:21:42 +00002349- Issue #2517: Allow unicode messages in Exceptions again by correctly

2354 set to a custom object whose write() method happens to install
2355 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002357- Issue #3088: Corrected a race condition in classes derived from
2358 threading.local: the first member set by a thread could be saved in
2359 another thread's dictionary.
2360
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002361- Issue #3004: Minor change to slice.indices(): the start and stop
2362 arguments are now treated identically, making the behaviour easier
2363 to describe and understand. For example, slice(None, -10,
2364 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2365 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2366 10, -1).
2367
Georg Brandl278fc502008-07-19 12:46:12 +00002368- Issue #3219: Calling a function with repeated keyword arguments,
2369 f(a=2, a=23), would not cause a syntax error. This was a regression
2370 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002371
Georg Brandl278fc502008-07-19 12:46:12 +00002372- Issue #2862: Make int and float freelist management consistent with
2373 other freelists. Changes their CompactFreeList apis into
2374 ClearFreeList apis and calls them via gc.collect().

2380 api functions without holding the GIL, which could lead to a fatal
2381 error when they failed.
2382
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002383- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002408- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2409 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002410 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002411 content-length. The problem had been corrected in the 2.4 branch, but never
2412 merged into trunk.
2413
Georg Brandle78fbcc2008-07-05 10:13:36 +00002414- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002427- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2428 handling is now the same as that of other special attributes like __name__).
2429
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002430- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002882- Issue #1631171: Re-implement the 'warnings' module in C (the
2883 original Python code has been kept as backup). This will allow for
2884 using the 'warning's machinery in such places as the parser where
2885 use of pure Python code is not possible. Both the ``showarning()``
2886 and ``formatwarning()`` gain an optional 'line' argument which is
2887 not called by default for backwards-compatibility reasons. Setting
2888 ``warnings.showwarning()`` to an implementation that lacks support
2889 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002952- Issue #2550: The approach used by client/server code for obtaining
2953 ports to listen on in network-oriented tests has been refined in an
2954 effort to facilitate running multiple instances of the entire
2955 regression test suite in parallel without issue.
2956 test_support.bind_port() has been fixed such that it will always
2957 return a unique port -- which wasn't always the case with the
2958 previous implementation, especially if socket options had been set
2959 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2960 new implementation of bind_port() will actually raise an exception
2961 if it is passed an AF_INET/SOCK_STREAM socket with either the
2962 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2963 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2964 the socket it's been passed. This currently only applies to
2965 Windows. This option prevents any other sockets from binding to the
2966 host/port we've bound to, thus removing the possibility of the
2967 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2968 when a second SOCK_STREAM socket binds and accepts to a host/port
2969 that's already been bound by another socket. The optional preferred
2970 port parameter to bind_port() has been removed. Under no
2971 circumstances should tests be hard coding ports!
2972
2973 test_support.find_unused_port() has also been introduced, which will
2974 pass a temporary socket object to bind_port() in order to obtain an
2975 unused port. The temporary socket object is then closed and
2976 deleted, and the port is returned. This method should only be used
2977 for obtaining an unused port in order to pass to an external program
2978 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2979 a parameter to a server-oriented class that doesn't give you direct
2980 access to the underlying socket used.
2981
2982 Finally, test_support.HOST has been introduced, which should be used
2983 for the host argument of any relevant socket calls (i.e. bind and
2984 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002985
2986 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002987 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002988 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2989 test_asynchat and test_socket_ssl.
2990
Georg Brandl3ee81df2008-05-17 18:14:43 +00002991 It is now possible for multiple instances of the regression test
2992 suite to run in parallel without issue.

3259-----------------
3260
Fred Drakea8ee94b2008-03-01 02:45:07 +00003261- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003262 644. The mode is now inherited from the py file.

3270
Eric Smitha73fbe72008-02-23 03:09:44 +00003271- Added the future_builtins module, which contains hex() and oct().
3272 These are the PEP 3127 version of these functions, designed to be
3273 compatible with the hex() and oct() builtins from Python 3.0. They
3274 differ slightly in their output formats from the existing, unchanged
3275 Python 2.6 builtins. The expected usage of the future_builtins
3276 module is:
3277 from future_builtins import hex, oct
3278
Eric Smith7ef40bf2008-02-20 23:34:22 +00003279- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3280 exponents for exponents with absolute value < 100. Follows C99
3281 standard. This is a change on Windows, which would use 3 digits.
3282 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3283 so that any alterations it does to the resulting string will be
3284 available in stringlib/formatter.h (for float.__format__).
3285
Eric Smith5a3c1352008-02-19 13:21:56 +00003286- Implemented PEP 3101, Advanced String Formatting. This adds a new
3287 builtin format(); a format() method for str and unicode; a
3288 __format__() method to object, str, unicode, int, long, float, and
3289 datetime; the class string.Formatter; and the C API
3290 PyObject_Format().
3291
Georg Brandl3ee81df2008-05-17 18:14:43 +00003292- Fixed several potential crashes, all caused by specially crafted
3293 __del__ methods exploiting objects in temporarily inconsistent
3294 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003295
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003296- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297 prevent a possible crash: an Abstract Base Class would try to access
3298 a slot on a registered virtual subclass.

3305 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Issue #2045: Fix an infinite recursion triggered when printing a

3309 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003310
Christian Heimesf75dbef2008-02-08 00:11:31 +00003311- Fixed a minor memory leak in dictobject.c. The content of the free
3312 list was not freed on interpreter shutdown.
3313
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314- Limit free list of method and builtin function objects to 256

3318 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003319 to compact the internal free lists of pre-allocted ints and floats.
3320
Georg Brandl3ee81df2008-05-17 18:14:43 +00003321- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3322 calls. Python expected the return type int but the fork familie
3323 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003337- Patch #1473257: generator objects gain a gi_code attribute. This is
3338 the same object as the func_code attribute of the function that
3339 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003340
Georg Brandl3ee81df2008-05-17 18:14:43 +00003341- Issue #1920: "while 0" statements were completely removed by the
3342 compiler, even in the presence of an "else" clause, which is
3343 supposed to be run when the condition is false. Now the compiler
3344 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003345

Georg Brandl6caad7d2008-01-26 14:19:22 +00003363- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003364 added.
3365
Christian Heimesc94e2b52008-01-14 04:13:37 +00003366- sys.float_info / PyFloat_GetInfo: The floating point information
3367 object was converted from a dict to a specialized structseq object.
3368
Georg Brandl3ee81df2008-05-17 18:14:43 +00003369- Patch #1816: Added sys.flags structseq. It exposes the status of
3370 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003371
Georg Brandl3ee81df2008-05-17 18:14:43 +00003372- Objects/structseq.c: Implemented new structseq representation. The
3373 patch makes structseqs (e.g. the return value of os.stat) more
3374 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- Patch #1700288: added a type attribute cache that caches method
3377 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003378
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003379- Bug #1776: __import__() no longer accepts filenames on any platform.
3380 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003381
Georg Brandlaed6c662008-01-07 17:25:53 +00003382- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3385 envvar and sys.dont_write_bytecode attribute. All these can be set
3386 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003387
Georg Brandl3ee81df2008-05-17 18:14:43 +00003388- Improve some exception messages when Windows fails to load an
3389 extension module. Now we get for example '%1 is not a valid Win32
3390 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003391
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003394- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3395 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003396
Christian Heimes0a8143f2007-12-18 23:22:54 +00003397- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003398 and INF. float("nan"), float("inf") and float("-inf") now work on
3399 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003400
Georg Brandl3ee81df2008-05-17 18:14:43 +00003401- Compiler now generates simpler and faster code for dictionary
3402 literals. The oparg for BUILD_MAP now indicates an estimated
3403 dictionary size. There is a new opcode, STORE_MAP, for adding
3404 entries to the dictionary.

3422 running, and if the deallocation of its frames somehow calls the
3423 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003424

3429
Georg Brandl3ee81df2008-05-17 18:14:43 +00003430- Issue #1460: The utf-7 incremental decoder did not accept truncated
3431 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003432
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Patch #1739468: Directories and zipfiles containing a __main__.py
3434 file can now be directly executed by passing their name to the
3435 interpreter. The directory/zipfile is automatically inserted as the
3436 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003437
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438- Issue #1265: Fix a problem with sys.settrace, if the tracing
3439 function uses a generator expression when at the same time the
3440 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003441
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003442- sets and frozensets now have an isdisjoint() method.
3443

3445
Neal Norwitz44f326e2007-10-05 05:29:17 +00003446- Fix warnings found by the new version of the Coverity checker.
3447
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- The enumerate() builtin function is no longer bounded to sequences
3449 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3450 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003451
Georg Brandl3ee81df2008-05-17 18:14:43 +00003452- Issue #1686386: Tuple's tp_repr did not take into account the
3453 possibility of having a self-referential tuple, which is possible
3454 from C code. Nor did object's tp_str consider that a type's tp_str
3455 could do something that could lead to an inifinite recursion.
3456 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3457 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003458
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459- Issue #1164: It was possible to trigger deadlock when using the
3460 'print' statement to write to a file since the GIL was not released
3461 as needed. Now PyObject_Print() does the right thing along with
3462 various tp_print implementations of the built-in types and those in
3463 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Issue #1147: Exceptions were directly allowing string exceptions in
3466 their throw() method even though string exceptions no longer
3467 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003468
Georg Brandl3ee81df2008-05-17 18:14:43 +00003469- Issue #1096: Prevent a segfault from getting the repr of a very
3470 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003471
Brett Cannon1e534b52007-09-07 04:18:30 +00003472- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003473 PyObject_Call() never calling back out to Python code to trigger
3474 recursion depth updates/checks. Required the creation of a static
3475 RuntimeError instance in case normalizing an exception put the
3476 recursion check value past its limit. Fixes crashers
3477 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003478
Georg Brandl3ee81df2008-05-17 18:14:43 +00003479- Patch #1031213: Decode source line in SyntaxErrors back to its

3483 with %G.
3484
Georg Brandl3ee81df2008-05-17 18:14:43 +00003485- Prevent expandtabs() on string and unicode objects from causing a
3486 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003492- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003493 __*__ attributes. (Some already existed, e.g., __doc__ and
3494 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003495
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003496- Add -3 option to the interpreter to warn about features that are
3497 deprecated and will be changed/removed in Python 3.0.
3498
Georg Brandl2134e752007-05-21 20:34:16 +00003499- Patch #1686487: you can now pass any mapping after '**' in function
3500 calls.
3501
Collin Winter62903052007-05-18 23:11:24 +00003502- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003503 "except E as target:". This is to provide forwards compatibility
3504 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003505
Brett Cannon229cee22007-05-05 01:34:02 +00003506- Deprecate BaseException.message as per PEP 352.
3507
Georg Brandl3ee81df2008-05-17 18:14:43 +00003508- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003509 inherited from a builtin base.
3510
Vinay Sajip8549ce32007-05-06 17:53:37 +00003511- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003512 setting a plain string, ie don't expand to single letter identifiers.
3513
Raymond Hettinger13936692007-04-11 18:40:58 +00003514- Request #1191699: Slices can now be pickled.
3515
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003516- Request #1193128: str.translate() now allows a None argument for
3517 translations that only remove characters without re-mapping the
3518 remaining characters.
3519
Georg Brandl5cb76c12007-03-21 09:00:39 +00003520- Patch #1682205: a TypeError while unpacking an iterable is no longer
3521 masked by a generic one with the message "unpack non-sequence".
3522
Neal Norwitzaa754b72007-03-21 06:39:48 +00003523- Remove unused file Python/fmod.c.
3524
Guido van Rossum143b5642007-03-23 04:58:42 +00003525- Bug #1683368: The object.__init__() and object.__new__() methods are
3526 now stricter in rejecting excess arguments. The only time when
3527 either allows excess arguments is when it is not overridden and the
3528 other one is. For backwards compatibility, when both are
3529 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003530 warning later). Also, type.__init__() insists on the same signature
3531 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003532
Georg Brandl3ee81df2008-05-17 18:14:43 +00003533- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3534 object to complex using its __complex__() method before falling back
3535 to the __float__() method. Therefore, the functions in the cmath
3536 module now can operate on objects that define a __complex__()
3537 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003538
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539- Patch #1623563: allow __class__ assignment for classes with
3540 __slots__. The old and the new class are still required to have the
3541 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003542
Georg Brandl3ee81df2008-05-17 18:14:43 +00003543- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003546- Patch #1462488: Python no longer segfaults when
3547 ``object.__reduce_ex__()`` is called with an object that is faking
3548 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003549
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003553- Patch #1444529: the builtin compile() now accepts keyword arguments.
3554
Georg Brandl7b9c5552007-03-12 14:30:05 +00003555- Bug #1678647: write a newline after printing an exception in any
3556 case, even when converting the value to a string failed.
3557
Georg Brandl871f1bc2007-03-12 13:17:36 +00003558- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003559 its argument, if it exists. If not, it will work like before. This
3560 allows customizing the output of dir() in the presence of a
3561 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003562
Collin Winter276887b2007-03-12 16:11:39 +00003563- Patch #922167: Python no longer segfaults when faced with infinitely
3564 self-recursive reload() calls (as reported by bug #742342).
3565
Georg Brandl3ee81df2008-05-17 18:14:43 +00003566- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003569- Patch #1491866: change the complex() constructor to allow
3570 parthensized forms. This means complex(repr(x)) now works instead of
3571 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003572
Georg Brandlaa2321b2007-03-07 00:40:28 +00003573- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574 makes the filenames the warning module prints much more sensible
3575 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003576
Georg Brandl49aafc92007-03-07 00:34:46 +00003577- Variant of patch #697613: don't exit the interpreter on a SystemExit
3578 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003579 variable is given, but break into the interactive interpreter just
3580 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003588- Patch #1674228: when assigning a slice (old-style), check for the
3589 sq_ass_slice instead of the sq_slice slot.
3590
Georg Brandl3ee81df2008-05-17 18:14:43 +00003591- When printing an unraisable error, don't print exceptions. before
3592 the name. This duplicates the behavior whening normally printing
3593 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003594
Georg Brandl3ee81df2008-05-17 18:14:43 +00003595- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004095- Added a timeout parameter to the constructor of other protocols
4096 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4097 work started with create_connection() and timeout in httplib, and
4098 closes patch #723312.
4099
Vinay Sajip8549ce32007-05-06 17:53:37 +00004100- Patch #1676823: Added create_connection() to socket.py, which may be
4101 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004102 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004103

4124
Georg Brandlf66b6032007-03-14 08:27:52 +00004125- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004126 AttributeError instead of an IOError when the server's response
4127 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004128
Georg Brandl3ee81df2008-05-17 18:14:43 +00004129- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004133- Patch #1429539: pdb now correctly initializes the __main__ module
4134 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004135 correctly now.
4136
Georg Brandlbad6f192007-03-13 21:32:56 +00004137- The nonobvious commands.getstatus() function is now deprecated.

4143
Georg Brandl3ee81df2008-05-17 18:14:43 +00004144- Patch #1530482: add pydoc.render_doc() which returns the

4155 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00004157- Patch #1581073: add a flag to textwrap that prevents the dropping of
4158 whitespace while wrapping.
4159
Georg Brandl92a6bae2007-03-13 17:43:32 +00004160- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004161 are set for invalid interpolation sequences that would lead to
4162 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004163

4203

4205 returned string up to the first NUL character.
4206

4216
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- unittest now verifies more of its assumptions. In particular,
4218 TestCase and TestSuite subclasses (not instances) are no longer
4219 accepted in TestSuite.addTest(). This should cause no
4220 incompatibility since it never made sense with ordinary subclasses
4221 -- the failure just occurred later, with a more cumbersome
4222 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004223

4232
Georg Brandl3ee81df2008-05-17 18:14:43 +00004233- Patch #1673619: setup.py identifies extension modules it doesn't

4593 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004610- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004611 time so that opening a database previously created with the DB_DUP
4612 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4613 opens. Specifically: dictionary assignment to a DB object will
4614 replace all values for a given key when the database allows
4615 duplicate values. DB users should use DB.put(k, v) when they want
4616 to store duplicates; not DB[k] = v.

4623 characters with ASCII value less than 32. Also, it correctly quotes
4624 dots only if they occur on a single line, as opposed to the previous
4625 behavior of quoting dots if they are the second character of any
4626 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004627
