86-----------------
87
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000088- Issue #7419: setlocale() could crash the interpreter on Windows when called
89 with invalid values.
90
Eric Smithc4ab8332009-11-29 17:40:57 +000091- Issue #3382: 'F' formatting for float and complex now convert the
92 result to upper case. This only affects 'inf' and 'nan', since 'f'
93 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000094
Mark Dickinson9dd5e162009-11-23 20:54:09 +000095- Remove switch from "%f" formatting to "%g" formatting for floats
96 larger than 1e50 in absolute value.
97
Mark Dickinson18cfada2009-11-23 18:46:41 +000098- Remove restrictions on precision when formatting floats. E.g.,
99 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
100 requested 120 significant digits instead.
101
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000102- Add Py3k warnings for parameter names in parenthesis.
103
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000104- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000105
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000106- Issue #7085: Fix crash when importing some extensions in a thread
107 on MacOSX 10.6.
108
Mark Dickinsonb678de82009-11-19 18:41:49 +0000109- Issue #7117: repr(x) for a float x returns a result based on the
110 shortest decimal string that's guaranteed to round back to x under
111 correct rounding (with round-half-to-even rounding mode).
112 Previously it gave a string based on rounding x to 17 decimal digits.
113 repr(x) for a complex number behaves similarly. On platforms where
114 the correctly-rounded strtod and dtoa code is not supported (see below),
115 repr is unchanged.
116
117- Issue #7117: On almost all platforms: float-to-string and
118 string-to-float conversions within Python are now correctly rounded.
119 Places these conversions occur include: str for floats and complex
120 numbers; the float and complex constructors; old-style and new-style
121 numeric formatting; serialization and deserialization of floats and
122 complex numbers using marshal, pickle and json; parsing of float and
123 imaginary literals in Python code; Decimal-to-float conversion.
124
125 The conversions use a Python-adapted version of David Gay's
126 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
127 functions. This code is supported on Windows, and on Unix-like
128 platforms using gcc, icc or suncc as the C compiler. There may be a
129 small number of platforms on which correct operation of this code
130 cannot be guaranteed, so the code is not used: notably, this applies
131 to platforms where the C double format is not IEEE 754 binary64, and
132 to platforms on x86 hardware where the x87 FPU is set to 64-bit
133 precision and Python's configure script is unable to determine how
134 to change the FPU precision. On these platforms conversions use the
135 platform strtod and dtoa, as before.
136
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000137- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000138 now uses the correctly-rounded string <-> float conversions
139 described above (when available), and so produces correctly rounded
140 results that will display nicely under the float repr. There are
141 two related small changes: (1) round now accepts any class with an
142 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000143 floats for the second argument), and (2) an excessively large second
144 integer argument (e.g., round(1.234, 10**100)) no longer raises an
145 exception.
146
Philip Jenveyfab8be22009-11-17 02:42:26 +0000147- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
148
Benjamin Petersone36199b2009-11-12 23:39:44 +0000149- Fix several issues with compile(). The input can now contain Windows and Mac
150 newlines and is no longer required to end in a newline.
151
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000152- Remove length limitation when constructing a complex number from a
153 unicode string.
154
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000155- Issue #7244: itertools.izip_longest() no longer ignores exceptions
156 raised during the formation of an output tuple.
157

163
Eric Smithc12781a2009-10-19 14:38:14 +0000164- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

193 of producing internally inconsistent Python longs.
194
Philip Jenveydbf3b252009-09-29 04:32:44 +0000195- Issue #6990: Fix threading.local subclasses leaving old state around

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000287- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
288 (1) inf and nan strings with trailing whitespace were incorrectly
289 rejected; (2) parsing of strings representing infinities and nans
290 was locale aware; and (3) the interpretation of fromhex('-nan')
291 didn't match that of float('-nan').
292
Eric Smitha985a3a2009-05-05 18:26:08 +0000293- Issue #5920: For float.__format__, change the behavior with the
294 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
295 to be like 'g' but with at least one decimal point and with a
296 default precision of 12. Previously, the behavior the same but with
297 a default precision of 6. This more closely matches str(), and
298 reduces surprises when adding alignment flags to the empty
299 presentation type. This also affects the new complex.__format__ in
300 the same way.
301
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000302- Issue #5890: in subclasses of 'property' the __doc__ attribute was

374 2**15 for the internal representation of integers, for performance
375 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
376 --enable-big-digits option to configure, which overrides the
377 default. Add sys.long_info structseq to provide information about
378 the internal format.

395 float arguments.
396
Raymond Hettinger08259e82009-02-18 23:10:19 +0000397- Running Python with the -3 option now also warns about classic division
398 for ints and longs.
399

401 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
402 on a 64-bit system.
403
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000404- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

411
Georg Brandl29c6a282009-04-05 20:23:13 +0000412- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000413 were suppressing all exceptions. These include list(), filter(), map(),
414 zip(), and bytearray().
415
Benjamin Peterson596d3062009-01-19 15:42:23 +0000416- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

425 to str, bytes and bytearray could be optimized away by the compiler, letting
426 the interpreter segfault instead of raising an error.
427
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000428- Issue #3720: Fix a crash when an iterator modifies its class and removes its

434
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000435- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
436 collecting the oldest generation) so that allocating lots of objects without
437 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000438 Martin von Löwis at

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000443- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
444 an existing .py counterpart, override the co_filename attributes of all
445 code objects if the original filename is obsolete (which can happen if the
446 file has been renamed, moved, or if it is accessed through different paths).
447 Patch by Ziga Seilnacht and Jean-Paul Calderone.

459
Benjamin Peterson7af65562008-12-29 17:56:58 +0000460- Issue #4764: With io.open, IOError.filename is set when trying to open a

468
Skip Montanarof205c132008-12-23 03:30:15 +0000469- Added test case to ensure attempts to read from a file opened for writing
470 fail.
471
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000472- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

485 exceptions.
486
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000487- Issue #4445: Replace "sizeof(PyStringObject)" with
488 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
489 str instances. On a typical machine this saves 3 bytes of memory
490 (on average) per string allocation.
491
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000492- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
493 interpreter to abort ("Fatal Python error: Could not reset the stack!")
494 instead of throwing a MemoryError.
495
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000496- Issue #3689: The list reversed iterator now supports __length_hint__

501
Vinay Sajip213faca2008-12-03 23:22:58 +0000502- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000503 method on file objects with closefd=False. The file descriptor is still
504 kept open but the file object behaves like a closed file. The ``FileIO``
505 object also got a new readonly attribute ``closefd``.
506
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000507- Issue #4348: Some bytearray methods returned that didn't cause any change to

521
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000522- Issue #4209: Enabling unicode_literals and the print_function in the same
523 __future__ import didn't work.
524
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000525- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000526 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000528- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
529 returned a path longer than MAX_PATH. (But It's doubtful this code path is
530 really executed because I cannot move to such directory on win2k)
531
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000532- Issue #4069: When set.remove(element) is used with a set element, the element
533 is temporarily replaced with an equivalent frozenset. But the eventual
534 KeyError would always report the empty frozenset([]) as the missing key. Now
535 it correctly refers to the initial element.

553 returned them on 64bit platforms.
554
Walter Dörwalded960ac2009-05-03 22:36:33 +0000555- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
556 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
557 step. This avoids problems with counting UTF-8 bytes that ignores the effect
558 of using the replace error handler in PyUnicode_DecodeUTF8().
559
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000560- Issue #3739: The unicode-internal encoder now reports the number of characters
561 consumed like any other encoder (instead of the number of bytes).
562
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000563- Issue #2422: When compiled with the ``--with-valgrind`` option, the
564 pymalloc allocator will be automatically disabled when running under
565 Valgrind. This gives improved memory leak detection when running
566 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou59c44f32009-10-30 17:07:08 +00001802- Issue #7222: Make thread "reaping" more reliable so that reference
1803 leak-chasing test runs give sensible results. The previous method of
1804 reaping threads could return successfully while some Thread objects were
1805 still referenced. This also introduces a new private function:

1833 test_heapq and test_warnings have been adjusted to use it, tests for
1834 other modules with both C and Python implementations in the stdlib
1835 can be adjusted to use it over time.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001948- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1949 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1950 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1951 ``printf`` function, whereas PyString_FromFormat has an independent
1952 implementation and uses "%zd" on all platforms for size_t values.
1953 This makes a difference on win64, where ``printf`` needs "%Id" to display

1960 object; previously an int would be returned for small values. the __long__
1961 method is allowed to return either an int or a long, but the behaviour of

2049 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2050 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002117What's New in Python 2.6 beta 3?
2118================================
2119
Barry Warsaw07a4a382008-08-21 01:15:08 +00002120*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002121
2122Core and Builtins
2123-----------------
2124
Guido van Rossumf8402962008-08-20 15:01:50 +00002125- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2126 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2127 extensions do not automatically benefit from the class attribute
2128 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2129 to their tp_flags field if they care. This is a backwards
2130 compatibility feature; in 3.0, all types will use the cache by
2131 default.
2132
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002133- Keyword arguments can now follow starred arguments. (``f(a, *args,
2134 keyword=23)`` is now valid syntax.)
2135
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002136- ctypes function pointers that are COM methods have a boolean True
2137 value again.
2138
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002139- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2140 by denying s# to parse objects that have a releasebuffer procedure,
2141 and introducing s*.
2142
Georg Brandl1e13ea92008-08-11 09:07:59 +00002143- Issue #3537: Fix an assertion failure when an empty but presized dict
2144 object was stored in the freelist.
2145
Mark Dickinsonb6467572008-08-04 21:30:09 +00002146- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2147 ValueError consistently across platforms.
2148
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002149- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2150 (64bit Unix, for example), unichr() would truncate its argument and return
2151 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2152
Neal Norwitze7d8be82008-07-31 17:17:14 +00002153- Apply security patches from Apple.
2154
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002155- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2156 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2157
Antoine Pitrou92f82162008-07-25 22:22:08 +00002158- Issue #1819: function calls with several named parameters are now on
2159 average 35% faster (as measured by pybench).
2160
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002161- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2162 the python debugger steps into a class statement: the free variables (local
2163 variables defined in an outer scope) would be deleted from the outer scope.
2164
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002165- Issue #2620: Overflow checking when allocating or reallocating memory
2166 was not always being done properly in some python types and extension
2167 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2168 all been updated to perform better checks and places in the code that
2169 would previously leak memory on the error path when such an allocation
2170 failed have been fixed.

2174
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002175- Issue #3612: Added some missing basic types in ctypes.wintypes.
2176
Benjamin Petersone977ad42008-08-20 01:42:01 +00002177- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2178 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2179
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002180- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2181 version reported by these tools does not necessarily follow the python
2182 version numbering scheme, so the module is less strict when parsing it.
2183
Nick Coghlanf70385a2008-08-18 12:42:46 +00002184- Issue #2235: Added Py3k warnings for types which will become unhashable
2185 under the stricter __hash__ inheritance rules in 3.0. Several types
2186 which did not meet the rules for hash invariants and were already
2187 unhashable in 3.0 have now been explicitly flagged as unhashable in
2188 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2189 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2190
Brett Cannon88f801d2008-08-18 00:46:22 +00002191- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2193
Brett Cannon7b96f072008-08-18 00:41:11 +00002194- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2195
Brett Cannon46225e72008-08-18 00:36:52 +00002196- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002198- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2199
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002200- Issue #3575: Incremental decoder's decode function now takes bytearray
2201 by using 's*' instead of 't#'.
2202
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002203- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002204 fails unicode conversion on 2nd parameter. (windows only)
2205
Facundo Batista94f243a2008-08-17 03:38:39 +00002206- Issue 2464. urllib2 now supports a malformation in the URL received
2207 in a redirect.
2208
Brett Cannonabe423e2008-08-16 21:47:07 +00002209- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002210 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002211
Facundo Batistaeb90b782008-08-16 14:44:07 +00002212- Issue #2776: fixed small issue when handling an URL with double slash
2213 after a 302 response in the case of not going through a proxy.
2214
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002215- Issue #2676: in the email package, content-type parsing was hanging on
2216 pathological input because of quadratic or exponential behaviour of a
2217 regular expression.
2218
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002219- Issue #3476: binary buffered reading through the new "io" library is now
2220 thread-safe.
2221
Brett Cannonbf3157b2008-08-14 05:00:03 +00002222- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2223 since mimetools itself is deprecated. Because modules are cached, all
2224 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2225
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002226- Issue #3134: shutil referenced undefined WindowsError symbol.
2227
Robert Schuppenies14646332008-08-10 11:01:53 +00002228- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2229 menu entries were not deleted.
2230
Brett Cannon83e81842008-08-09 23:30:55 +00002231- Copied the implementation of reduce() to _functools.reduce() to have a
2232 version that did not raise a DeprecationWarning under -3.
2233
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002234- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2235 a MemoryError rather than silently stop the iteration.
2236
Guido van Rossum59ce9012008-08-09 14:55:34 +00002237- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2238 to _sre.compile() will now be rejected. This should not affect anybody
2239 since the re.compile() function never generates invalid re-bytecode.
2240
Skip Montanaroa032bf42008-08-08 22:52:51 +00002241- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2242 upon first access it can be automatically initialized from the csv file if
2243 it wasn't initialized during instantiation.
2244
Brett Cannon3aa2a492008-08-06 22:28:09 +00002245- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2246 the reload() built-in has been removed.
2247
Brett Cannon7e30b672008-08-04 21:52:25 +00002248- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002249 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002260 asking for a specific length. This problem only affected files opened
2261 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002262

2289
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002290- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002311What's New in Python 2.6 beta 2?
2312================================
2313
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002314*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002316Core and Builtins
2317-----------------
2318
Georg Brandl3e483f62008-07-16 22:57:41 +00002319- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2320 its methods now allow for items objects that can be converted to
2321 an integer using operator.index().
2322
Mark Dickinson64b7e502008-07-16 09:40:03 +00002323- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2324 produced a ValueError instead of giving the correct float.
2325
Eric Smitha5fa5a22008-07-16 00:11:49 +00002326- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2327 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2328
Mark Dickinson7103aa42008-07-15 19:08:33 +00002329- Issue #3008: the float type has a new instance method 'float.hex'
2330 and a new class method 'float.fromhex' to convert floating-point
2331 numbers to and from hexadecimal strings, respectively.
2332
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002333- Issue #2235: __hash__ is once again inherited by default. To allow
2334 collections.Hashable to remain meaningful in the presence of the
2335 default hash implementation (object.__hash__), it is now possible
2336 to explicit block inheritance of hash by setting __hash__=None at
2337 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2338 level.
2339
Nick Coghlanb028f502008-07-13 14:52:36 +00002340- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2341 the parent module cannot be found while performing an absolute import.
2342 This means that an incorrectly defined __package__ attribute will
2343 now only prevent relative imports in that module rather than causing
2344 all imports from that module to fail.
2345
Nick Coghlan14ff9942008-07-08 14:21:42 +00002346- Issue #2517: Allow unicode messages in Exceptions again by correctly
2347 bypassing the instance dictionary when looking up __unicode__ on
2348 new-style classes.

2351 set to a custom object whose write() method happens to install
2352 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002354- Issue #3088: Corrected a race condition in classes derived from
2355 threading.local: the first member set by a thread could be saved in
2356 another thread's dictionary.
2357
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002358- Issue #3004: Minor change to slice.indices(): the start and stop
2359 arguments are now treated identically, making the behaviour easier
2360 to describe and understand. For example, slice(None, -10,
2361 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2362 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2363 10, -1).
2364
Georg Brandl278fc502008-07-19 12:46:12 +00002365- Issue #3219: Calling a function with repeated keyword arguments,
2366 f(a=2, a=23), would not cause a syntax error. This was a regression
2367 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002368
Georg Brandl278fc502008-07-19 12:46:12 +00002369- Issue #2862: Make int and float freelist management consistent with
2370 other freelists. Changes their CompactFreeList apis into
2371 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002376- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2377 api functions without holding the GIL, which could lead to a fatal
2378 error when they failed.
2379
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002380- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002404
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002405- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2406 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002407 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002408 content-length. The problem had been corrected in the 2.4 branch, but never
2409 merged into trunk.
2410
Georg Brandle78fbcc2008-07-05 10:13:36 +00002411- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002424- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2425 handling is now the same as that of other special attributes like __name__).
2426
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002427- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002879- Issue #1631171: Re-implement the 'warnings' module in C (the
2880 original Python code has been kept as backup). This will allow for
2881 using the 'warning's machinery in such places as the parser where
2882 use of pure Python code is not possible. Both the ``showarning()``
2883 and ``formatwarning()`` gain an optional 'line' argument which is
2884 not called by default for backwards-compatibility reasons. Setting
2885 ``warnings.showwarning()`` to an implementation that lacks support
2886 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Issue #2550: The approach used by client/server code for obtaining
2950 ports to listen on in network-oriented tests has been refined in an
2951 effort to facilitate running multiple instances of the entire
2952 regression test suite in parallel without issue.
2953 test_support.bind_port() has been fixed such that it will always
2954 return a unique port -- which wasn't always the case with the
2955 previous implementation, especially if socket options had been set
2956 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2957 new implementation of bind_port() will actually raise an exception
2958 if it is passed an AF_INET/SOCK_STREAM socket with either the
2959 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2960 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2961 the socket it's been passed. This currently only applies to
2962 Windows. This option prevents any other sockets from binding to the
2963 host/port we've bound to, thus removing the possibility of the
2964 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2965 when a second SOCK_STREAM socket binds and accepts to a host/port
2966 that's already been bound by another socket. The optional preferred
2967 port parameter to bind_port() has been removed. Under no
2968 circumstances should tests be hard coding ports!
2969
2970 test_support.find_unused_port() has also been introduced, which will
2971 pass a temporary socket object to bind_port() in order to obtain an
2972 unused port. The temporary socket object is then closed and
2973 deleted, and the port is returned. This method should only be used
2974 for obtaining an unused port in order to pass to an external program
2975 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2976 a parameter to a server-oriented class that doesn't give you direct
2977 access to the underlying socket used.
2978
2979 Finally, test_support.HOST has been introduced, which should be used
2980 for the host argument of any relevant socket calls (i.e. bind and
2981 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002982
2983 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002984 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002985 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2986 test_asynchat and test_socket_ssl.
2987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988 It is now possible for multiple instances of the regression test
2989 suite to run in parallel without issue.

3256-----------------
3257
Fred Drakea8ee94b2008-03-01 02:45:07 +00003258- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003259 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003264
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003265- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003266 issue 215555 for a discussion.
3267
Eric Smitha73fbe72008-02-23 03:09:44 +00003268- Added the future_builtins module, which contains hex() and oct().
3269 These are the PEP 3127 version of these functions, designed to be
3270 compatible with the hex() and oct() builtins from Python 3.0. They
3271 differ slightly in their output formats from the existing, unchanged
3272 Python 2.6 builtins. The expected usage of the future_builtins
3273 module is:
3274 from future_builtins import hex, oct
3275
Eric Smith7ef40bf2008-02-20 23:34:22 +00003276- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3277 exponents for exponents with absolute value < 100. Follows C99
3278 standard. This is a change on Windows, which would use 3 digits.
3279 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3280 so that any alterations it does to the resulting string will be
3281 available in stringlib/formatter.h (for float.__format__).
3282
Eric Smith5a3c1352008-02-19 13:21:56 +00003283- Implemented PEP 3101, Advanced String Formatting. This adds a new
3284 builtin format(); a format() method for str and unicode; a
3285 __format__() method to object, str, unicode, int, long, float, and
3286 datetime; the class string.Formatter; and the C API
3287 PyObject_Format().
3288
Georg Brandl3ee81df2008-05-17 18:14:43 +00003289- Fixed several potential crashes, all caused by specially crafted
3290 __del__ methods exploiting objects in temporarily inconsistent
3291 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003292
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003293- Issue #2115: Important speedup in setting __slot__ attributes. Also

3302 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003303
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304- Issue #2045: Fix an infinite recursion triggered when printing a

3315 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003316 to compact the internal free lists of pre-allocted ints and floats.
3317
Georg Brandl3ee81df2008-05-17 18:14:43 +00003318- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3319 calls. Python expected the return type int but the fork familie
3320 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003334- Patch #1473257: generator objects gain a gi_code attribute. This is
3335 the same object as the func_code attribute of the function that
3336 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003337
Georg Brandl3ee81df2008-05-17 18:14:43 +00003338- Issue #1920: "while 0" statements were completely removed by the
3339 compiler, even in the presence of an "else" clause, which is
3340 supposed to be run when the condition is false. Now the compiler
3341 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003342

Georg Brandl6caad7d2008-01-26 14:19:22 +00003360- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003361 added.
3362
Christian Heimesc94e2b52008-01-14 04:13:37 +00003363- sys.float_info / PyFloat_GetInfo: The floating point information
3364 object was converted from a dict to a specialized structseq object.
3365
Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- Patch #1816: Added sys.flags structseq. It exposes the status of
3367 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003368
Georg Brandl3ee81df2008-05-17 18:14:43 +00003369- Objects/structseq.c: Implemented new structseq representation. The
3370 patch makes structseqs (e.g. the return value of os.stat) more
3371 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003372
Georg Brandl3ee81df2008-05-17 18:14:43 +00003373- Patch #1700288: added a type attribute cache that caches method
3374 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003375
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003376- Bug #1776: __import__() no longer accepts filenames on any platform.
3377 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003378
Georg Brandlaed6c662008-01-07 17:25:53 +00003379- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3380
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3382 envvar and sys.dont_write_bytecode attribute. All these can be set
3383 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003384
Georg Brandl3ee81df2008-05-17 18:14:43 +00003385- Improve some exception messages when Windows fails to load an
3386 extension module. Now we get for example '%1 is not a valid Win32
3387 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003388

Georg Brandl3ee81df2008-05-17 18:14:43 +00003391- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3392 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003393
Christian Heimes0a8143f2007-12-18 23:22:54 +00003394- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395 and INF. float("nan"), float("inf") and float("-inf") now work on
3396 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003397
Georg Brandl3ee81df2008-05-17 18:14:43 +00003398- Compiler now generates simpler and faster code for dictionary
3399 literals. The oparg for BUILD_MAP now indicates an estimated
3400 dictionary size. There is a new opcode, STORE_MAP, for adding
3401 entries to the dictionary.

3419 running, and if the deallocation of its frames somehow calls the
3420 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003421

Georg Brandl3ee81df2008-05-17 18:14:43 +00003430- Patch #1739468: Directories and zipfiles containing a __main__.py
3431 file can now be directly executed by passing their name to the
3432 interpreter. The directory/zipfile is automatically inserted as the
3433 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Issue #1265: Fix a problem with sys.settrace, if the tracing
3436 function uses a generator expression when at the same time the
3437 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003438
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003439- sets and frozensets now have an isdisjoint() method.
3440

3442
Neal Norwitz44f326e2007-10-05 05:29:17 +00003443- Fix warnings found by the new version of the Coverity checker.
3444
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- The enumerate() builtin function is no longer bounded to sequences
3446 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3447 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003448
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449- Issue #1686386: Tuple's tp_repr did not take into account the
3450 possibility of having a self-referential tuple, which is possible
3451 from C code. Nor did object's tp_str consider that a type's tp_str
3452 could do something that could lead to an inifinite recursion.
3453 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3454 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003455
Georg Brandl3ee81df2008-05-17 18:14:43 +00003456- Issue #1164: It was possible to trigger deadlock when using the
3457 'print' statement to write to a file since the GIL was not released
3458 as needed. Now PyObject_Print() does the right thing along with
3459 various tp_print implementations of the built-in types and those in
3460 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003461
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Issue #1147: Exceptions were directly allowing string exceptions in
3463 their throw() method even though string exceptions no longer
3464 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003465
Georg Brandl3ee81df2008-05-17 18:14:43 +00003466- Issue #1096: Prevent a segfault from getting the repr of a very
3467 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003468
Brett Cannon1e534b52007-09-07 04:18:30 +00003469- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003470 PyObject_Call() never calling back out to Python code to trigger
3471 recursion depth updates/checks. Required the creation of a static
3472 RuntimeError instance in case normalizing an exception put the
3473 recursion check value past its limit. Fixes crashers
3474 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003475
Georg Brandl3ee81df2008-05-17 18:14:43 +00003476- Patch #1031213: Decode source line in SyntaxErrors back to its

3480 with %G.
3481
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00003489- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003490 __*__ attributes. (Some already existed, e.g., __doc__ and
3491 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003492
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003493- Add -3 option to the interpreter to warn about features that are
3494 deprecated and will be changed/removed in Python 3.0.
3495
Georg Brandl2134e752007-05-21 20:34:16 +00003496- Patch #1686487: you can now pass any mapping after '**' in function
3497 calls.
3498
Collin Winter62903052007-05-18 23:11:24 +00003499- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500 "except E as target:". This is to provide forwards compatibility
3501 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003502
Brett Cannon229cee22007-05-05 01:34:02 +00003503- Deprecate BaseException.message as per PEP 352.
3504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003506 inherited from a builtin base.
3507
Vinay Sajip8549ce32007-05-06 17:53:37 +00003508- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003509 setting a plain string, ie don't expand to single letter identifiers.
3510
Raymond Hettinger13936692007-04-11 18:40:58 +00003511- Request #1191699: Slices can now be pickled.
3512
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003513- Request #1193128: str.translate() now allows a None argument for
3514 translations that only remove characters without re-mapping the
3515 remaining characters.
3516
Georg Brandl5cb76c12007-03-21 09:00:39 +00003517- Patch #1682205: a TypeError while unpacking an iterable is no longer
3518 masked by a generic one with the message "unpack non-sequence".
3519
Neal Norwitzaa754b72007-03-21 06:39:48 +00003520- Remove unused file Python/fmod.c.
3521
Guido van Rossum143b5642007-03-23 04:58:42 +00003522- Bug #1683368: The object.__init__() and object.__new__() methods are
3523 now stricter in rejecting excess arguments. The only time when
3524 either allows excess arguments is when it is not overridden and the
3525 other one is. For backwards compatibility, when both are
3526 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003527 warning later). Also, type.__init__() insists on the same signature
3528 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003529
Georg Brandl3ee81df2008-05-17 18:14:43 +00003530- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3531 object to complex using its __complex__() method before falling back
3532 to the __float__() method. Therefore, the functions in the cmath
3533 module now can operate on objects that define a __complex__()
3534 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003535
Georg Brandl3ee81df2008-05-17 18:14:43 +00003536- Patch #1623563: allow __class__ assignment for classes with
3537 __slots__. The old and the new class are still required to have the
3538 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003539

Georg Brandl3ee81df2008-05-17 18:14:43 +00003543- Patch #1462488: Python no longer segfaults when
3544 ``object.__reduce_ex__()`` is called with an object that is faking
3545 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003546
Georg Brandl3ee81df2008-05-17 18:14:43 +00003547- Patch #1680015: Don't modify __slots__ tuple if it contains an

3551
Georg Brandl7b9c5552007-03-12 14:30:05 +00003552- Bug #1678647: write a newline after printing an exception in any
3553 case, even when converting the value to a string failed.
3554
Georg Brandl871f1bc2007-03-12 13:17:36 +00003555- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003556 its argument, if it exists. If not, it will work like before. This
3557 allows customizing the output of dir() in the presence of a
3558 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003559
Collin Winter276887b2007-03-12 16:11:39 +00003560- Patch #922167: Python no longer segfaults when faced with infinitely
3561 self-recursive reload() calls (as reported by bug #742342).
3562
Georg Brandl3ee81df2008-05-17 18:14:43 +00003563- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003566- Patch #1491866: change the complex() constructor to allow
3567 parthensized forms. This means complex(repr(x)) now works instead of
3568 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003569
Georg Brandlaa2321b2007-03-07 00:40:28 +00003570- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003571 makes the filenames the warning module prints much more sensible
3572 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003573
Georg Brandl49aafc92007-03-07 00:34:46 +00003574- Variant of patch #697613: don't exit the interpreter on a SystemExit
3575 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003576 variable is given, but break into the interactive interpreter just
3577 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003585- Patch #1674228: when assigning a slice (old-style), check for the
3586 sq_ass_slice instead of the sq_slice slot.
3587
Georg Brandl3ee81df2008-05-17 18:14:43 +00003588- When printing an unraisable error, don't print exceptions. before
3589 the name. This duplicates the behavior whening normally printing
3590 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003591
Georg Brandl3ee81df2008-05-17 18:14:43 +00003592- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004092- Added a timeout parameter to the constructor of other protocols
4093 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4094 work started with create_connection() and timeout in httplib, and
4095 closes patch #723312.
4096
Vinay Sajip8549ce32007-05-06 17:53:37 +00004097- Patch #1676823: Added create_connection() to socket.py, which may be
4098 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004099 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004100

4121
Georg Brandlf66b6032007-03-14 08:27:52 +00004122- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123 AttributeError instead of an IOError when the server's response
4124 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004125
Georg Brandl3ee81df2008-05-17 18:14:43 +00004126- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004130- Patch #1429539: pdb now correctly initializes the __main__ module
4131 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004132 correctly now.
4133
Georg Brandlbad6f192007-03-13 21:32:56 +00004134- The nonobvious commands.getstatus() function is now deprecated.

4140
Georg Brandl3ee81df2008-05-17 18:14:43 +00004141- Patch #1530482: add pydoc.render_doc() which returns the

4151 parameter which can be set to False to prevent the default
4152 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00004153
Georg Brandl9e6b4702007-03-13 18:15:41 +00004154- Patch #1581073: add a flag to textwrap that prevents the dropping of
4155 whitespace while wrapping.
4156
Georg Brandl92a6bae2007-03-13 17:43:32 +00004157- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158 are set for invalid interpolation sequences that would lead to
4159 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004160

4200

4202 returned string up to the first NUL character.
4203

4213
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214- unittest now verifies more of its assumptions. In particular,
4215 TestCase and TestSuite subclasses (not instances) are no longer
4216 accepted in TestSuite.addTest(). This should cause no
4217 incompatibility since it never made sense with ordinary subclasses
4218 -- the failure just occurred later, with a more cumbersome
4219 exception.

4229
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230- Patch #1673619: setup.py identifies extension modules it doesn't

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004607- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004608 time so that opening a database previously created with the DB_DUP
4609 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4610 opens. Specifically: dictionary assignment to a DB object will
4611 replace all values for a given key when the database allows
4612 duplicate values. DB users should use DB.put(k, v) when they want
4613 to store duplicates; not DB[k] = v.

4620 characters with ASCII value less than 32. Also, it correctly quotes
4621 dots only if they occur on a single line, as opposed to the previous
4622 behavior of quoting dots if they are the second character of any
4623 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004624
