12Core and Builtins
13-----------------
14
Mark Dickinsonbd15a062009-11-18 19:33:35 +000015- Issue #7117: Backport round implementation from Python 3.x. round
16 now uses David Gay's correctly-rounded string <-> double conversions
17 (when available), and so produces correctly rounded results. There
18 are two related small changes: (1) round now accepts any class with
19 an __index__ method for its second argument (but no longer accepts
20 floats for the second argument), and (2) an excessively large second
21 integer argument (e.g., round(1.234, 10**100)) no longer raises an
22 exception.

151 statement and correctly lookup the __enter__ and __exit__ special methods.
152
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000153- Issue #5829: complex("1e500") no longer raises OverflowError. This
154 makes it consistent with float("1e500") and interpretation of real

165 (1) inf and nan strings with trailing whitespace were incorrectly
166 rejected; (2) parsing of strings representing infinities and nans
167 was locale aware; and (3) the interpretation of fromhex('-nan')
168 didn't match that of float('-nan').
169
Eric Smitha985a3a2009-05-05 18:26:08 +0000170- Issue #5920: For float.__format__, change the behavior with the
171 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
172 to be like 'g' but with at least one decimal point and with a
173 default precision of 12. Previously, the behavior the same but with
174 a default precision of 6. This more closely matches str(), and
175 reduces surprises when adding alignment flags to the empty
176 presentation type. This also affects the new complex.__format__ in
177 the same way.
178
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000179- Issue #5890: in subclasses of 'property' the __doc__ attribute was

188
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000189- Issue #5864: Fix empty format code formatting for floats so that it
190 never gives more than the requested number of significant digits.
191

204 z involves nans, infs or negative zeros.
205
Eric Smithaca19e62009-04-22 13:29:05 +0000206- Implement PEP 378, Format Specifier for Thousands Separator, for
207 floats, ints, and longs.
208
209- Issue #5515: 'n' formatting for ints, longs, and floats handles
210 leading zero formatting poorly.
211
212- Issue #5772: For float.__format__, don't add a trailing ".0" if
213 we're using no type code and we have an exponent.

219 some builtin types.
220
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000221- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000222 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000223
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000224- Issue #5759: float() didn't call __float__ on str subclasses.

242 untrackable objects are not tracked by the garbage collector. This can
243 reduce the size of collections and therefore the garbage collection overhead
244 on long-running programs, depending on their particular use of datatypes.
245
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000246- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

251 2**15 for the internal representation of integers, for performance
252 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
253 --enable-big-digits option to configure, which overrides the
254 default. Add sys.long_info structseq to provide information about

266
Brett Cannon6c4cff02009-03-11 04:51:06 +0000267- Issue #3652: Make the 'line' argument for warnings.showwarning() a
268 requirement. Means the DeprecationWarning from Python 2.6 can go away.

278 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
279 on a 64-bit system.
280
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000281- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

288
Georg Brandl29c6a282009-04-05 20:23:13 +0000289- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000290 were suppressing all exceptions. These include list(), filter(), map(),
291 zip(), and bytearray().
292
Benjamin Peterson596d3062009-01-19 15:42:23 +0000293- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000312- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
313 collecting the oldest generation) so that allocating lots of objects without
314 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000315 Martin von Löwis at

319
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000320- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
321 an existing .py counterpart, override the co_filename attributes of all
322 code objects if the original filename is obsolete (which can happen if the
323 file has been renamed, moved, or if it is accessed through different paths).
324 Patch by Ziga Seilnacht and Jean-Paul Calderone.
325
Martin v. Löwis5344c992009-01-02 20:32:55 +0000326- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000328- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
329 file with `str' filename on Windows.
330
Antoine Pitrouaa687902009-01-01 14:11:22 +0000331- Issue #3680: Reference cycles created through a dict, set or deque iterator
332 did not get collected.
333
Nick Coghlan180e4002008-12-30 01:18:48 +0000334- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types

336
Benjamin Peterson7af65562008-12-29 17:56:58 +0000337- Issue #4764: With io.open, IOError.filename is set when trying to open a

344 bytearray.translate(). It was always allowed for bytes.translate().
345
Skip Montanarof205c132008-12-23 03:30:15 +0000346- Added test case to ensure attempts to read from a file opened for writing
347 fail.
348
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000349- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

360
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000361- Issue #4597: Fixed several opcodes that weren't always propagating
362 exceptions.
363
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000364- Issue #4445: Replace "sizeof(PyStringObject)" with
365 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
366 str instances. On a typical machine this saves 3 bytes of memory
367 (on average) per string allocation.
368
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000369- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
370 interpreter to abort ("Fatal Python error: Could not reset the stack!")
371 instead of throwing a MemoryError.
372
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000373- Issue #3689: The list reversed iterator now supports __length_hint__
374 instead of __len__. Behavior now matches other reversed iterators.
375
Benjamin Petersonc078f922008-11-21 22:27:24 +0000376- Issue #4367: Python would segfault during compiling when the unicodedata
377 module couldn't be imported and \N escapes were present.
378
Vinay Sajip213faca2008-12-03 23:22:58 +0000379- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000380 method on file objects with closefd=False. The file descriptor is still
381 kept open but the file object behaves like a closed file. The ``FileIO``
382 object also got a new readonly attribute ``closefd``.
383
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000384- Issue #4348: Some bytearray methods returned that didn't cause any change to
385 the bytearray, returned the same bytearray instead of a copy.
386
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000387- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
388
Benjamin Peterson273c2332008-11-17 22:39:09 +0000389- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
390
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000391- Issue #4048: The parser module now correctly validates relative imports.
392
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000393- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

395
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000396- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
397 method does not return iterators for the 4th and 5th items.
398
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000399- Issue #4209: Enabling unicode_literals and the print_function in the same
400 __future__ import didn't work.
401
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000402- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000403 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000404
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000405- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
406 returned a path longer than MAX_PATH. (But It's doubtful this code path is
407 really executed because I cannot move to such directory on win2k)
408
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000409- Issue #4069: When set.remove(element) is used with a set element, the element
410 is temporarily replaced with an equivalent frozenset. But the eventual
411 KeyError would always report the empty frozenset([]) as the missing key. Now
412 it correctly refers to the initial element.
413
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000414- Issue #4509: Various issues surrounding resize of bytearray objects to
415 which there are buffer exports.
416

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000429- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
430 returned them on 64bit platforms.
431
Walter Dörwalded960ac2009-05-03 22:36:33 +0000432- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
433 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
434 step. This avoids problems with counting UTF-8 bytes that ignores the effect
435 of using the replace error handler in PyUnicode_DecodeUTF8().
436
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000437- Issue #3739: The unicode-internal encoder now reports the number of characters
438 consumed like any other encoder (instead of the number of bytes).

459
Nick Coghlan49868cb2009-11-15 07:30:34 +0000460- Issue #6816: runpy now provides a run_path function that allows Python code
461 to execute file paths that refer to source or compiled Python files as well
462 as zipfiles, directories and other valid sys.path entries that contain a
463 __main__.py file. This allows applications that run other Python scripts to

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001762- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1763
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001764- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1765 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1766 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1767 ``printf`` function, whereas PyString_FromFormat has an independent
1768 implementation and uses "%zd" on all platforms for size_t values.
1769 This makes a difference on win64, where ``printf`` needs "%Id" to display
1770 64bit values.
1771
Benjamin Peterson97179b02008-09-09 20:55:01 +00001772- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001775- Issue #3777: long() applied to a float object now always return a long
1776 object; previously an int would be returned for small values. the __long__
1777 method is allowed to return either an int or a long, but the behaviour of
1778 float objects should not change to respect backward compatibility.
1779
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001780- Issue #3751: str.rpartition would perform a left-partition when called with
1781 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001786 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001787 was correctly parsed but parsing of subsequent arguments failed.
1788
Vinay Sajip35e3b032008-09-01 14:33:59 +00001789- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001790 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1791 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1792 when given a tuple of classes as second argument, were looking up
1793 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1794 type object.
1795
Neal Norwitz18aa3882008-08-24 05:04:52 +00001796- Fix crashes on memory allocation failure found with failmalloc.

1939-----------------
1940
Guido van Rossumf8402962008-08-20 15:01:50 +00001941- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1942 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1943 extensions do not automatically benefit from the class attribute
1944 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1945 to their tp_flags field if they care. This is a backwards
1946 compatibility feature; in 3.0, all types will use the cache by
1947 default.
1948
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001949- Keyword arguments can now follow starred arguments. (``f(a, *args,
1950 keyword=23)`` is now valid syntax.)
1951
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001952- ctypes function pointers that are COM methods have a boolean True
1953 value again.
1954
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001955- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1956 by denying s# to parse objects that have a releasebuffer procedure,
1957 and introducing s*.
1958
Georg Brandl1e13ea92008-08-11 09:07:59 +00001959- Issue #3537: Fix an assertion failure when an empty but presized dict
1960 object was stored in the freelist.
1961
Mark Dickinsonb6467572008-08-04 21:30:09 +00001962- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1963 ValueError consistently across platforms.
1964
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001965- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1966 (64bit Unix, for example), unichr() would truncate its argument and return
1967 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1968
Neal Norwitze7d8be82008-07-31 17:17:14 +00001969- Apply security patches from Apple.
1970
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001971- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1972 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1973
Antoine Pitrou92f82162008-07-25 22:22:08 +00001974- Issue #1819: function calls with several named parameters are now on
1975 average 35% faster (as measured by pybench).
1976
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001977- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1978 the python debugger steps into a class statement: the free variables (local
1979 variables defined in an outer scope) would be deleted from the outer scope.
1980
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001981- Issue #2620: Overflow checking when allocating or reallocating memory
1982 was not always being done properly in some python types and extension
1983 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1984 all been updated to perform better checks and places in the code that
1985 would previously leak memory on the error path when such an allocation
1986 failed have been fixed.

Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001996- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1997 version reported by these tools does not necessarily follow the python
1998 version numbering scheme, so the module is less strict when parsing it.
1999
Nick Coghlanf70385a2008-08-18 12:42:46 +00002000- Issue #2235: Added Py3k warnings for types which will become unhashable
2001 under the stricter __hash__ inheritance rules in 3.0. Several types
2002 which did not meet the rules for hash invariants and were already
2003 unhashable in 3.0 have now been explicitly flagged as unhashable in
2004 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2005 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2006
Brett Cannon88f801d2008-08-18 00:46:22 +00002007- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2036 thread-safe.
2037
Brett Cannonbf3157b2008-08-14 05:00:03 +00002038- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2039 since mimetools itself is deprecated. Because modules are cached, all
2040 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2041
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002042- Issue #3134: shutil referenced undefined WindowsError symbol.

2054 to _sre.compile() will now be rejected. This should not affect anybody
2055 since the re.compile() function never generates invalid re-bytecode.
2056
Skip Montanaroa032bf42008-08-08 22:52:51 +00002057- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2058 upon first access it can be automatically initialized from the csv file if
2059 it wasn't initialized during instantiation.
2060
Brett Cannon3aa2a492008-08-06 22:28:09 +00002061- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2062 the reload() built-in has been removed.
2063
Brett Cannon7e30b672008-08-04 21:52:25 +00002064- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002065 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2073 raised an AttributeError.
2074
Benjamin Peterson01a24322008-07-28 23:35:27 +00002075- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002076 asking for a specific length. This problem only affected files opened
2077 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002078

2103 file name rather than a ZipInfo instance, so files are extracted with
2104 mode 0600 rather than 000 under Unix.
2105
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002106- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2119 interaction with the tp_hash slot (added in 2.6b2) are now documented
2120
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002121- Issue #643841: The language reference now provides more detailed
2122 coverage of the lookup process for special methods. The disclaimers
2123 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002127What's New in Python 2.6 beta 2?
2128================================
2129
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002130*Release date: 17-Jul-2008*
2131
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002132Core and Builtins
2133-----------------
2134
Georg Brandl3e483f62008-07-16 22:57:41 +00002135- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2136 its methods now allow for items objects that can be converted to
2137 an integer using operator.index().
2138
Mark Dickinson64b7e502008-07-16 09:40:03 +00002139- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2140 produced a ValueError instead of giving the correct float.
2141
Eric Smitha5fa5a22008-07-16 00:11:49 +00002142- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2143 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2144
Mark Dickinson7103aa42008-07-15 19:08:33 +00002145- Issue #3008: the float type has a new instance method 'float.hex'
2146 and a new class method 'float.fromhex' to convert floating-point
2147 numbers to and from hexadecimal strings, respectively.
2148
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002149- Issue #2235: __hash__ is once again inherited by default. To allow
2150 collections.Hashable to remain meaningful in the presence of the
2151 default hash implementation (object.__hash__), it is now possible
2152 to explicit block inheritance of hash by setting __hash__=None at
2153 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2154 level.
2155
Nick Coghlanb028f502008-07-13 14:52:36 +00002156- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2157 the parent module cannot be found while performing an absolute import.
2158 This means that an incorrectly defined __package__ attribute will
2159 now only prevent relative imports in that module rather than causing
2160 all imports from that module to fail.
2161
Nick Coghlan14ff9942008-07-08 14:21:42 +00002162- Issue #2517: Allow unicode messages in Exceptions again by correctly
2163 bypassing the instance dictionary when looking up __unicode__ on
2164 new-style classes.
2165
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002166- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2167 set to a custom object whose write() method happens to install
2168 another file in sys.stdout.
2169
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002170- Issue #3088: Corrected a race condition in classes derived from
2171 threading.local: the first member set by a thread could be saved in
2172 another thread's dictionary.
2173
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002174- Issue #3004: Minor change to slice.indices(): the start and stop
2175 arguments are now treated identically, making the behaviour easier
2176 to describe and understand. For example, slice(None, -10,
2177 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2178 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2179 10, -1).
2180
Georg Brandl278fc502008-07-19 12:46:12 +00002181- Issue #3219: Calling a function with repeated keyword arguments,
2182 f(a=2, a=23), would not cause a syntax error. This was a regression
2183 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002184
Georg Brandl278fc502008-07-19 12:46:12 +00002185- Issue #2862: Make int and float freelist management consistent with
2186 other freelists. Changes their CompactFreeList apis into
2187 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002188

2190-------
2191
Thomas Heller57adf222008-08-14 19:10:48 +00002192- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2193 api functions without holding the GIL, which could lead to a fatal
2194 error when they failed.
2195
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002196- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2205 ForkingPickler.register() to resolve conflict with ctypes.
2206
Vinay Sajip51e65192008-07-18 09:01:10 +00002207- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002208
Thomas Heller880f5292008-07-15 19:39:38 +00002209- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2210 a valid dlerror() message.
2211
Thomas Heller2bad6572008-07-15 17:19:50 +00002212- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2213 incomplete structure was created.
2214

2218
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002219- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002220
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002221- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2222 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002223 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002224 content-length. The problem had been corrected in the 2.4 branch, but never
2225 merged into trunk.
2226
Georg Brandle78fbcc2008-07-05 10:13:36 +00002227- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002238 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002239
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002240- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2241 handling is now the same as that of other special attributes like __name__).
2242
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002243- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2244 removal in Python 3.0 in favor of urllib2.urlopen().

2632 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002633 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002634
2635 This is controlled by the configure argument ``--with-universal-archs``:
2636
2637 - ``--with-universal-archs=all``: install 4-way universal
2638
2639 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2640
2641 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2642
2643 This option should be used in combination with ``--enable-universalsdk=``.
2644
2645 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002695- Issue #1631171: Re-implement the 'warnings' module in C (the
2696 original Python code has been kept as backup). This will allow for
2697 using the 'warning's machinery in such places as the parser where
2698 use of pure Python code is not possible. Both the ``showarning()``
2699 and ``formatwarning()`` gain an optional 'line' argument which is
2700 not called by default for backwards-compatibility reasons. Setting
2701 ``warnings.showwarning()`` to an implementation that lacks support
2702 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002765- Issue #2550: The approach used by client/server code for obtaining
2766 ports to listen on in network-oriented tests has been refined in an
2767 effort to facilitate running multiple instances of the entire
2768 regression test suite in parallel without issue.
2769 test_support.bind_port() has been fixed such that it will always
2770 return a unique port -- which wasn't always the case with the
2771 previous implementation, especially if socket options had been set
2772 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2773 new implementation of bind_port() will actually raise an exception
2774 if it is passed an AF_INET/SOCK_STREAM socket with either the
2775 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2776 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2777 the socket it's been passed. This currently only applies to
2778 Windows. This option prevents any other sockets from binding to the
2779 host/port we've bound to, thus removing the possibility of the
2780 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2781 when a second SOCK_STREAM socket binds and accepts to a host/port
2782 that's already been bound by another socket. The optional preferred
2783 port parameter to bind_port() has been removed. Under no
2784 circumstances should tests be hard coding ports!
2785
2786 test_support.find_unused_port() has also been introduced, which will
2787 pass a temporary socket object to bind_port() in order to obtain an
2788 unused port. The temporary socket object is then closed and
2789 deleted, and the port is returned. This method should only be used
2790 for obtaining an unused port in order to pass to an external program
2791 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2792 a parameter to a server-oriented class that doesn't give you direct
2793 access to the underlying socket used.
2794
2795 Finally, test_support.HOST has been introduced, which should be used
2796 for the host argument of any relevant socket calls (i.e. bind and
2797 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002798
2799 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002801 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2802 test_asynchat and test_socket_ssl.
2803
Georg Brandl3ee81df2008-05-17 18:14:43 +00002804 It is now possible for multiple instances of the regression test
2805 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002859- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2861 Plane. This affected raw unicode literals and the
2862 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2863 this case, like normal unicode literals and the 'unicode-escape'
2864 codec.

3083
Eric Smitha73fbe72008-02-23 03:09:44 +00003084- Added the future_builtins module, which contains hex() and oct().
3085 These are the PEP 3127 version of these functions, designed to be
3086 compatible with the hex() and oct() builtins from Python 3.0. They
3087 differ slightly in their output formats from the existing, unchanged
3088 Python 2.6 builtins. The expected usage of the future_builtins
3089 module is:

3091
Eric Smith7ef40bf2008-02-20 23:34:22 +00003092- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3093 exponents for exponents with absolute value < 100. Follows C99
3094 standard. This is a change on Windows, which would use 3 digits.
3095 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3096 so that any alterations it does to the resulting string will be
3097 available in stringlib/formatter.h (for float.__format__).
3098
Eric Smith5a3c1352008-02-19 13:21:56 +00003099- Implemented PEP 3101, Advanced String Formatting. This adds a new
3100 builtin format(); a format() method for str and unicode; a
3101 __format__() method to object, str, unicode, int, long, float, and
3102 datetime; the class string.Formatter; and the C API
3103 PyObject_Format().
3104
Georg Brandl3ee81df2008-05-17 18:14:43 +00003105- Fixed several potential crashes, all caused by specially crafted
3106 __del__ methods exploiting objects in temporarily inconsistent
3107 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003108
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003109- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110 prevent a possible crash: an Abstract Base Class would try to access
3111 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003112

Georg Brandl3ee81df2008-05-17 18:14:43 +00003116- Clear all free lists during a gc.collect() of the highest generation
3117 in order to allow pymalloc to free more arenas. Python may give back
3118 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003119
Georg Brandl3ee81df2008-05-17 18:14:43 +00003120- Issue #2045: Fix an infinite recursion triggered when printing a
3121 subclass of collections.defaultdict, if its default_factory is set
3122 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00003124- Fixed a minor memory leak in dictobject.c. The content of the free
3125 list was not freed on interpreter shutdown.
3126
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127- Limit free list of method and builtin function objects to 256
3128 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3131 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003132 to compact the internal free lists of pre-allocted ints and floats.
3133
Georg Brandl3ee81df2008-05-17 18:14:43 +00003134- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3135 calls. Python expected the return type int but the fork familie
3136 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003137
Georg Brandl3ee81df2008-05-17 18:14:43 +00003138- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Patch #1473257: generator objects gain a gi_code attribute. This is
3151 the same object as the func_code attribute of the function that
3152 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Issue #1920: "while 0" statements were completely removed by the
3155 compiler, even in the presence of an "else" clause, which is
3156 supposed to be run when the condition is false. Now the compiler
3157 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003158
Guido van Rossumeead05f2008-01-24 18:21:02 +00003159- A few crashers fixed: weakref_in_del.py (issue #1377858);
3160 loosing_dict_ref.py (issue #1303614, test67.py);
3161 borrowed_ref_[34].py (not in tracker).
3162
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003163- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003164 suppressed while an extension is loaded by calling SetErrorMode in
3165 dynload_win.c. The error is still reported properly.
3166
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003168 several extension methods and modules do not work without unicode
3169 support.
3170
Georg Brandl26543b12008-01-21 18:36:51 +00003171- Issue #1882: when compiling code from a string, encoding cookies in the
3172 second line of code were not always recognized correctly.
3173
Georg Brandl14404b62008-01-19 19:27:05 +00003174- Issue #1679: "0x" was taken as a valid integer literal.
3175
Georg Brandl6caad7d2008-01-26 14:19:22 +00003176- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003177 added.
3178
Christian Heimesc94e2b52008-01-14 04:13:37 +00003179- sys.float_info / PyFloat_GetInfo: The floating point information
3180 object was converted from a dict to a specialized structseq object.
3181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- Patch #1816: Added sys.flags structseq. It exposes the status of
3183 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Objects/structseq.c: Implemented new structseq representation. The
3186 patch makes structseqs (e.g. the return value of os.stat) more
3187 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003188
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189- Patch #1700288: added a type attribute cache that caches method
3190 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003191
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003192- Bug #1776: __import__() no longer accepts filenames on any platform.
3193 The first parameter to __import__() must be a valid module name.

3198 envvar and sys.dont_write_bytecode attribute. All these can be set
3199 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003200
Georg Brandl3ee81df2008-05-17 18:14:43 +00003201- Improve some exception messages when Windows fails to load an
3202 extension module. Now we get for example '%1 is not a valid Win32
3203 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003204

3260
Georg Brandl3ee81df2008-05-17 18:14:43 +00003261- The enumerate() builtin function is no longer bounded to sequences
3262 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3263 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003264
Georg Brandl3ee81df2008-05-17 18:14:43 +00003265- Issue #1686386: Tuple's tp_repr did not take into account the
3266 possibility of having a self-referential tuple, which is possible
3267 from C code. Nor did object's tp_str consider that a type's tp_str
3268 could do something that could lead to an inifinite recursion.
3269 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3270 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003271
Georg Brandl3ee81df2008-05-17 18:14:43 +00003272- Issue #1164: It was possible to trigger deadlock when using the
3273 'print' statement to write to a file since the GIL was not released
3274 as needed. Now PyObject_Print() does the right thing along with
3275 various tp_print implementations of the built-in types and those in
3276 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003277

Georg Brandl3ee81df2008-05-17 18:14:43 +00003286 PyObject_Call() never calling back out to Python code to trigger
3287 recursion depth updates/checks. Required the creation of a static
3288 RuntimeError instance in case normalizing an exception put the
3289 recursion check value past its limit. Fixes crashers

3313 calls.
3314
Collin Winter62903052007-05-18 23:11:24 +00003315- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316 "except E as target:". This is to provide forwards compatibility
3317 with Python 3.0.

3337
Guido van Rossum143b5642007-03-23 04:58:42 +00003338- Bug #1683368: The object.__init__() and object.__new__() methods are
3339 now stricter in rejecting excess arguments. The only time when
3340 either allows excess arguments is when it is not overridden and the
3341 other one is. For backwards compatibility, when both are
3342 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003343 warning later). Also, type.__init__() insists on the same signature
3344 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003346- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3347 object to complex using its __complex__() method before falling back
3348 to the __float__() method. Therefore, the functions in the cmath
3349 module now can operate on objects that define a __complex__()
3350 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003368- Bug #1678647: write a newline after printing an exception in any
3369 case, even when converting the value to a string failed.
3370
Georg Brandl871f1bc2007-03-12 13:17:36 +00003371- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003372 its argument, if it exists. If not, it will work like before. This
3373 allows customizing the output of dir() in the presence of a
3374 __getattr__().

3384 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003386- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387 makes the filenames the warning module prints much more sensible
3388 when a PYTHONSTARTUP file is used.

3402 sq_ass_slice instead of the sq_slice slot.
3403
Georg Brandl3ee81df2008-05-17 18:14:43 +00003404- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00003456- Bug #1545497: when given an explicit base, int() did ignore NULs
3457 embedded in the string to convert.
3458
Georg Brandl846f73a2006-10-08 07:11:54 +00003459- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003507 generator expressions (x for x, in ... ) works again. Fixing this
3508 problem required changing the .pyc magic number. This means that
3509 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003939 AttributeError instead of an IOError when the server's response

4031 TestCase and TestSuite subclasses (not instances) are no longer

4034 -- the failure just occurred later, with a more cumbersome
4035 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004312- The implementation of UnicodeError objects has been simplified
4313 (start and end attributes are now stored directly as Py_ssize_t
4314 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004315
Georg Brandl3ee81df2008-05-17 18:14:43 +00004316- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4317 with RFC 3207 and forgets any knowledge obtained from the server not
4318 obtained from the TLS negotiation itself. Patch contributed by Bill
4319 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004320
Georg Brandl3ee81df2008-05-17 18:14:43 +00004321- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004322 that the SMTP.starttls() caller no longer needs to call ehlo()
4323 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004324 does not claim to support starttls. Adds the
4325 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4326 Fenner.

4406 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4407 silently miscode subclasses of those types. Now, it raises a
4408 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004409

Georg Brandl3ee81df2008-05-17 18:14:43 +00004424 time so that opening a database previously created with the DB_DUP
4425 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4426 opens. Specifically: dictionary assignment to a DB object will
4427 replace all values for a given key when the database allows
4428 duplicate values. DB users should use DB.put(k, v) when they want
4429 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004430

4436 characters with ASCII value less than 32. Also, it correctly quotes
4437 dots only if they occur on a single line, as opposed to the previous
4438 behavior of quoting dots if they are the second character of any
4439 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004440
