Georg Brandld2094602008-12-05 08:51:30 +0000393 method on file objects with closefd=False. The file descriptor is still

603 302 conformant loader) will now work correctly in most cases (they
604 are still subject to the constraints that exist for all code running

764What's New in Python 2.6.1
765==========================
766
767*Release date: 04-Dec-2008*
768
769Core and Builtins
770-----------------
771
772- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
773 interpreter to abort ("Fatal Python error: Could not reset the stack!")
774 instead of throwing a MemoryError.
775
776- Issue #4367: Python would segfault during compiling when the unicodedata
777 module couldn't be imported and \N escapes were present.
778
779- Issue #4348: Some bytearray methods returned that didn't cause any change to
780 the bytearray, returned the same bytearray instead of a copy.
781
782- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
783
784- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
785
786- Issue #4048: The parser module now correctly validates relative imports.
787
788- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

793
794- Issue #4209: Enabling unicode_literals and the print_function in the same
795 __future__ import didn't work.
796
797- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
798 returned a path longer than MAX_PATH. (But It's doubtful this code path is
799 really executed because I cannot move to such directory on win2k)
800
801- Issue #4069: When set.remove(element) is used with a set element, the element
802 is temporarily replaced with an equivalent frozenset. But the eventual
803 KeyError would always report the empty frozenset([]) as the missing key. Now
804 it correctly refers to the initial element.
805
806- Fixed C99 style comments in several files. Python is now C89 compatible
807 again.

955
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000956- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
957 PyString_FromFormat or PyErr_Format to display size_t values. The macro
958 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
959 ``printf`` function, whereas PyString_FromFormat has an independent

961 This makes a difference on win64, where ``printf`` needs "%Id" to display

1057 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1058 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001081- Issue #2975: When compiling several extension modules with Visual Studio 2008
1082 from the same python interpreter, some environment variables would grow
1083 without limit.
1084
Benjamin Peterson37346b22008-08-23 20:27:43 +00001085- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001122What's New in Python 2.6 beta 3?
1123================================
1124
Barry Warsaw07a4a382008-08-21 01:15:08 +00001125*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001126
1127Core and Builtins
1128-----------------
1129
Guido van Rossumf8402962008-08-20 15:01:50 +00001130- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1131 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1132 extensions do not automatically benefit from the class attribute
1133 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1134 to their tp_flags field if they care. This is a backwards
1135 compatibility feature; in 3.0, all types will use the cache by
1136 default.
1137
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001138- Keyword arguments can now follow starred arguments. (``f(a, *args,
1139 keyword=23)`` is now valid syntax.)
1140
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001141- ctypes function pointers that are COM methods have a boolean True
1142 value again.
1143
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001144- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1145 by denying s# to parse objects that have a releasebuffer procedure,
1146 and introducing s*.
1147
Georg Brandl1e13ea92008-08-11 09:07:59 +00001148- Issue #3537: Fix an assertion failure when an empty but presized dict
1149 object was stored in the freelist.
1150
Mark Dickinsonb6467572008-08-04 21:30:09 +00001151- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1152 ValueError consistently across platforms.
1153
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001154- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1155 (64bit Unix, for example), unichr() would truncate its argument and return
1156 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1157
Neal Norwitze7d8be82008-07-31 17:17:14 +00001158- Apply security patches from Apple.
1159
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001160- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1161 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1162
Antoine Pitrou92f82162008-07-25 22:22:08 +00001163- Issue #1819: function calls with several named parameters are now on
1164 average 35% faster (as measured by pybench).
1165
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001166- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1167 the python debugger steps into a class statement: the free variables (local
1168 variables defined in an outer scope) would be deleted from the outer scope.
1169
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001170- Issue #2620: Overflow checking when allocating or reallocating memory
1171 was not always being done properly in some python types and extension
1172 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1173 all been updated to perform better checks and places in the code that
1174 would previously leak memory on the error path when such an allocation
1175 failed have been fixed.

1179
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001180- Issue #3612: Added some missing basic types in ctypes.wintypes.
1181
Benjamin Petersone977ad42008-08-20 01:42:01 +00001182- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1183 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1184
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001185- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1186 version reported by these tools does not necessarily follow the python
1187 version numbering scheme, so the module is less strict when parsing it.
1188
Nick Coghlanf70385a2008-08-18 12:42:46 +00001189- Issue #2235: Added Py3k warnings for types which will become unhashable
1190 under the stricter __hash__ inheritance rules in 3.0. Several types
1191 which did not meet the rules for hash invariants and were already
1192 unhashable in 3.0 have now been explicitly flagged as unhashable in
1193 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1194 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1195
Brett Cannon88f801d2008-08-18 00:46:22 +00001196- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1197 imported into the module but exposed as part of the module's API.
1198
Brett Cannon7b96f072008-08-18 00:41:11 +00001199- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1200
Brett Cannon46225e72008-08-18 00:36:52 +00001201- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001203- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1204
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001205- Issue #3575: Incremental decoder's decode function now takes bytearray
1206 by using 's*' instead of 't#'.
1207
Jesus Cea585ad8a2009-07-02 15:37:21 +00001208- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001209 fails unicode conversion on 2nd parameter. (windows only)
1210
Facundo Batista94f243a2008-08-17 03:38:39 +00001211- Issue 2464. urllib2 now supports a malformation in the URL received
1212 in a redirect.
1213
Brett Cannonabe423e2008-08-16 21:47:07 +00001214- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001215 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001216
Facundo Batistaeb90b782008-08-16 14:44:07 +00001217- Issue #2776: fixed small issue when handling an URL with double slash
1218 after a 302 response in the case of not going through a proxy.
1219
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001220- Issue #2676: in the email package, content-type parsing was hanging on
1221 pathological input because of quadratic or exponential behaviour of a
1222 regular expression.
1223
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001224- Issue #3476: binary buffered reading through the new "io" library is now
1225 thread-safe.
1226
Brett Cannonbf3157b2008-08-14 05:00:03 +00001227- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1228 since mimetools itself is deprecated. Because modules are cached, all
1229 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1230
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001231- Issue #3134: shutil referenced undefined WindowsError symbol.
1232
Robert Schuppenies14646332008-08-10 11:01:53 +00001233- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1234 menu entries were not deleted.
1235
Brett Cannon83e81842008-08-09 23:30:55 +00001236- Copied the implementation of reduce() to _functools.reduce() to have a
1237 version that did not raise a DeprecationWarning under -3.
1238
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001239- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1240 a MemoryError rather than silently stop the iteration.
1241
Guido van Rossum59ce9012008-08-09 14:55:34 +00001242- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1243 to _sre.compile() will now be rejected. This should not affect anybody
1244 since the re.compile() function never generates invalid re-bytecode.
1245
Skip Montanaroa032bf42008-08-08 22:52:51 +00001246- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1247 upon first access it can be automatically initialized from the csv file if
1248 it wasn't initialized during instantiation.
1249
Brett Cannon3aa2a492008-08-06 22:28:09 +00001250- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1251 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00001265 asking for a specific length. This problem only affected files opened
1266 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001267

1292 file name rather than a ZipInfo instance, so files are extracted with
1293 mode 0600 rather than 000 under Unix.

Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001295- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1296 argument in python 2.5, this broke code that subclassed Popen to include its
1297 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1309
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001310- Issue #643841: The language reference now provides more detailed
1311 coverage of the lookup process for special methods. The disclaimers
1312 regarding lack of coverage of new-style classes have also been
1313 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001316What's New in Python 2.6 beta 2?
1317================================
1318
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001319*Release date: 17-Jul-2008*
1320
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001321Core and Builtins
1322-----------------
1323
Georg Brandl3e483f62008-07-16 22:57:41 +00001324- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1325 its methods now allow for items objects that can be converted to
1326 an integer using operator.index().
1327
Mark Dickinson64b7e502008-07-16 09:40:03 +00001328- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1329 produced a ValueError instead of giving the correct float.
1330
Eric Smitha5fa5a22008-07-16 00:11:49 +00001331- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1332 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1333
Mark Dickinson7103aa42008-07-15 19:08:33 +00001334- Issue #3008: the float type has a new instance method 'float.hex'
1335 and a new class method 'float.fromhex' to convert floating-point
1336 numbers to and from hexadecimal strings, respectively.
1337
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001338- Issue #2235: __hash__ is once again inherited by default. To allow
1339 collections.Hashable to remain meaningful in the presence of the
1340 default hash implementation (object.__hash__), it is now possible
1341 to explicit block inheritance of hash by setting __hash__=None at
1342 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1343 level.
1344
Nick Coghlanb028f502008-07-13 14:52:36 +00001345- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1346 the parent module cannot be found while performing an absolute import.
1347 This means that an incorrectly defined __package__ attribute will
1348 now only prevent relative imports in that module rather than causing
1349 all imports from that module to fail.
1350
Nick Coghlan14ff9942008-07-08 14:21:42 +00001351- Issue #2517: Allow unicode messages in Exceptions again by correctly
1352 bypassing the instance dictionary when looking up __unicode__ on
1353 new-style classes.
1354
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001355- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1356 set to a custom object whose write() method happens to install
1357 another file in sys.stdout.
1358
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001359- Issue #3088: Corrected a race condition in classes derived from
1360 threading.local: the first member set by a thread could be saved in
1361 another thread's dictionary.
1362
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001363- Issue #3004: Minor change to slice.indices(): the start and stop
1364 arguments are now treated identically, making the behaviour easier
1365 to describe and understand. For example, slice(None, -10,
1366 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1367 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1368 10, -1).
1369
Georg Brandl278fc502008-07-19 12:46:12 +00001370- Issue #3219: Calling a function with repeated keyword arguments,
1371 f(a=2, a=23), would not cause a syntax error. This was a regression
1372 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001373
Georg Brandl278fc502008-07-19 12:46:12 +00001374- Issue #2862: Make int and float freelist management consistent with
1375 other freelists. Changes their CompactFreeList apis into
1376 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001381- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1382 api functions without holding the GIL, which could lead to a fatal
1383 error when they failed.
1384
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001385- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1394 ForkingPickler.register() to resolve conflict with ctypes.
1395
Vinay Sajip51e65192008-07-18 09:01:10 +00001396- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001397
Thomas Heller880f5292008-07-15 19:39:38 +00001398- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1399 a valid dlerror() message.

1407
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001408- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001409
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001410- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1411 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001412 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001413 content-length. The problem had been corrected in the 2.4 branch, but never
1414 merged into trunk.
1415
Georg Brandle78fbcc2008-07-05 10:13:36 +00001416- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001429- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1430 handling is now the same as that of other special attributes like __name__).
1431
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001432- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

1889 not called by default for backwards-compatibility reasons. Setting
1890 ``warnings.showwarning()`` to an implementation that lacks support
1891 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001954- Issue #2550: The approach used by client/server code for obtaining
1955 ports to listen on in network-oriented tests has been refined in an
1956 effort to facilitate running multiple instances of the entire
1957 regression test suite in parallel without issue.
1958 test_support.bind_port() has been fixed such that it will always
1959 return a unique port -- which wasn't always the case with the
1960 previous implementation, especially if socket options had been set
1961 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1962 new implementation of bind_port() will actually raise an exception
1963 if it is passed an AF_INET/SOCK_STREAM socket with either the
1964 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1965 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1966 the socket it's been passed. This currently only applies to
1967 Windows. This option prevents any other sockets from binding to the
1968 host/port we've bound to, thus removing the possibility of the
1969 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1970 when a second SOCK_STREAM socket binds and accepts to a host/port
1971 that's already been bound by another socket. The optional preferred
1972 port parameter to bind_port() has been removed. Under no
1973 circumstances should tests be hard coding ports!
1974
1975 test_support.find_unused_port() has also been introduced, which will
1976 pass a temporary socket object to bind_port() in order to obtain an
1977 unused port. The temporary socket object is then closed and
1978 deleted, and the port is returned. This method should only be used
1979 for obtaining an unused port in order to pass to an external program
1980 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1981 a parameter to a server-oriented class that doesn't give you direct
1982 access to the underlying socket used.
1983
1984 Finally, test_support.HOST has been introduced, which should be used
1985 for the host argument of any relevant socket calls (i.e. bind and
1986 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001987
1988 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001989 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2261-----------------
2262
Fred Drakea8ee94b2008-03-01 02:45:07 +00002263- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002264 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002269
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002270- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002271 issue 215555 for a discussion.
2272
Eric Smitha73fbe72008-02-23 03:09:44 +00002273- Added the future_builtins module, which contains hex() and oct().
2274 These are the PEP 3127 version of these functions, designed to be
2275 compatible with the hex() and oct() builtins from Python 3.0. They
2276 differ slightly in their output formats from the existing, unchanged
2277 Python 2.6 builtins. The expected usage of the future_builtins
2278 module is:
2279 from future_builtins import hex, oct
2280
Eric Smith7ef40bf2008-02-20 23:34:22 +00002281- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2282 exponents for exponents with absolute value < 100. Follows C99
2283 standard. This is a change on Windows, which would use 3 digits.
2284 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2285 so that any alterations it does to the resulting string will be
2286 available in stringlib/formatter.h (for float.__format__).
2287
Eric Smith5a3c1352008-02-19 13:21:56 +00002288- Implemented PEP 3101, Advanced String Formatting. This adds a new
2289 builtin format(); a format() method for str and unicode; a
2290 __format__() method to object, str, unicode, int, long, float, and
2291 datetime; the class string.Formatter; and the C API
2292 PyObject_Format().
2293
Georg Brandl3ee81df2008-05-17 18:14:43 +00002294- Fixed several potential crashes, all caused by specially crafted
2295 __del__ methods exploiting objects in temporarily inconsistent
2296 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002297
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002298- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002299 prevent a possible crash: an Abstract Base Class would try to access
2300 a slot on a registered virtual subclass.

2307 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002308
Georg Brandl3ee81df2008-05-17 18:14:43 +00002309- Issue #2045: Fix an infinite recursion triggered when printing a

2311 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002312
Christian Heimesf75dbef2008-02-08 00:11:31 +00002313- Fixed a minor memory leak in dictobject.c. The content of the free
2314 list was not freed on interpreter shutdown.
2315
Georg Brandl3ee81df2008-05-17 18:14:43 +00002316- Limit free list of method and builtin function objects to 256

2320 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002321 to compact the internal free lists of pre-allocted ints and floats.
2322
Georg Brandl3ee81df2008-05-17 18:14:43 +00002323- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2324 calls. Python expected the return type int but the fork familie
2325 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002339- Patch #1473257: generator objects gain a gi_code attribute. This is
2340 the same object as the func_code attribute of the function that
2341 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002342
Georg Brandl3ee81df2008-05-17 18:14:43 +00002343- Issue #1920: "while 0" statements were completely removed by the
2344 compiler, even in the presence of an "else" clause, which is
2345 supposed to be run when the condition is false. Now the compiler
2346 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002347

Georg Brandl3ee81df2008-05-17 18:14:43 +00002374- Objects/structseq.c: Implemented new structseq representation. The
2375 patch makes structseqs (e.g. the return value of os.stat) more
2376 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002377
Georg Brandl3ee81df2008-05-17 18:14:43 +00002378- Patch #1700288: added a type attribute cache that caches method
2379 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002380
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002381- Bug #1776: __import__() no longer accepts filenames on any platform.
2382 The first parameter to __import__() must be a valid module name.

2387 envvar and sys.dont_write_bytecode attribute. All these can be set
2388 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002390- Improve some exception messages when Windows fails to load an
2391 extension module. Now we get for example '%1 is not a valid Win32
2392 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002393

Georg Brandl3ee81df2008-05-17 18:14:43 +00002400 and INF. float("nan"), float("inf") and float("-inf") now work on
2401 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002403- Compiler now generates simpler and faster code for dictionary
2404 literals. The oparg for BUILD_MAP now indicates an estimated
2405 dictionary size. There is a new opcode, STORE_MAP, for adding
2406 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Patch #1739468: Directories and zipfiles containing a __main__.py
2436 file can now be directly executed by passing their name to the
2437 interpreter. The directory/zipfile is automatically inserted as the
2438 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002440- Issue #1265: Fix a problem with sys.settrace, if the tracing
2441 function uses a generator expression when at the same time the
2442 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002443
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002444- sets and frozensets now have an isdisjoint() method.

2449
Georg Brandl3ee81df2008-05-17 18:14:43 +00002450- The enumerate() builtin function is no longer bounded to sequences
2451 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2452 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002453
Georg Brandl3ee81df2008-05-17 18:14:43 +00002454- Issue #1686386: Tuple's tp_repr did not take into account the
2455 possibility of having a self-referential tuple, which is possible
2456 from C code. Nor did object's tp_str consider that a type's tp_str
2457 could do something that could lead to an inifinite recursion.
2458 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2459 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002460
Georg Brandl3ee81df2008-05-17 18:14:43 +00002461- Issue #1164: It was possible to trigger deadlock when using the
2462 'print' statement to write to a file since the GIL was not released
2463 as needed. Now PyObject_Print() does the right thing along with
2464 various tp_print implementations of the built-in types and those in
2465 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002466
Georg Brandl3ee81df2008-05-17 18:14:43 +00002467- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00002473
Brett Cannon1e534b52007-09-07 04:18:30 +00002474- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002475 PyObject_Call() never calling back out to Python code to trigger
2476 recursion depth updates/checks. Required the creation of a static
2477 RuntimeError instance in case normalizing an exception put the
2478 recursion check value past its limit. Fixes crashers
2479 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002494- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002495 __*__ attributes. (Some already existed, e.g., __doc__ and
2496 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002497
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002498- Add -3 option to the interpreter to warn about features that are

2500
Georg Brandl2134e752007-05-21 20:34:16 +00002501- Patch #1686487: you can now pass any mapping after '**' in function
2502 calls.
2503
Collin Winter62903052007-05-18 23:11:24 +00002504- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002505 "except E as target:". This is to provide forwards compatibility
2506 with Python 3.0.

2512
Vinay Sajip8549ce32007-05-06 17:53:37 +00002513- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002514 setting a plain string, ie don't expand to single letter identifiers.
2515
Raymond Hettinger13936692007-04-11 18:40:58 +00002516- Request #1191699: Slices can now be pickled.
2517
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002518- Request #1193128: str.translate() now allows a None argument for

2520 remaining characters.
2521
Georg Brandl5cb76c12007-03-21 09:00:39 +00002522- Patch #1682205: a TypeError while unpacking an iterable is no longer

2524
Neal Norwitzaa754b72007-03-21 06:39:48 +00002525- Remove unused file Python/fmod.c.
2526
Guido van Rossum143b5642007-03-23 04:58:42 +00002527- Bug #1683368: The object.__init__() and object.__new__() methods are
2528 now stricter in rejecting excess arguments. The only time when
2529 either allows excess arguments is when it is not overridden and the
2530 other one is. For backwards compatibility, when both are
2531 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002532 warning later). Also, type.__init__() insists on the same signature
2533 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002534
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2536 object to complex using its __complex__() method before falling back
2537 to the __float__() method. Therefore, the functions in the cmath
2538 module now can operate on objects that define a __complex__()
2539 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002540
Georg Brandl3ee81df2008-05-17 18:14:43 +00002541- Patch #1623563: allow __class__ assignment for classes with
2542 __slots__. The old and the new class are still required to have the
2543 same slot names.

2556
Georg Brandl7b9c5552007-03-12 14:30:05 +00002557- Bug #1678647: write a newline after printing an exception in any
2558 case, even when converting the value to a string failed.
2559
Georg Brandl871f1bc2007-03-12 13:17:36 +00002560- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002561 its argument, if it exists. If not, it will work like before. This
2562 allows customizing the output of dir() in the presence of a
2563 __getattr__().

2573 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002574
Georg Brandlaa2321b2007-03-07 00:40:28 +00002575- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002576 makes the filenames the warning module prints much more sensible
2577 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002578

Georg Brandl0fca97a2007-03-05 22:28:08 +00002590- Patch #1674228: when assigning a slice (old-style), check for the
2591 sq_ass_slice instead of the sq_slice slot.
2592
Georg Brandl3ee81df2008-05-17 18:14:43 +00002593- When printing an unraisable error, don't print exceptions. before
2594 the name. This duplicates the behavior whening normally printing
2595 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003128 AttributeError instead of an IOError when the server's response
3129 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003130

Georg Brandl3ee81df2008-05-17 18:14:43 +00003135- Patch #1429539: pdb now correctly initializes the __main__ module
3136 for the debugged script, which means that imports from __main__ work

3145
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146- Patch #1530482: add pydoc.render_doc() which returns the

3161
Georg Brandl92a6bae2007-03-13 17:43:32 +00003162- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003163 are set for invalid interpolation sequences that would lead to
3164 errors on reading back those values.

3207 returned string up to the first NUL character.

3218
Georg Brandl3ee81df2008-05-17 18:14:43 +00003219- unittest now verifies more of its assumptions. In particular,
3220 TestCase and TestSuite subclasses (not instances) are no longer
3221 accepted in TestSuite.addTest(). This should cause no
3222 incompatibility since it never made sense with ordinary subclasses
3223 -- the failure just occurred later, with a more cumbersome
3224 exception.

3595 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003612- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003613 time so that opening a database previously created with the DB_DUP
3614 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3615 opens. Specifically: dictionary assignment to a DB object will
3616 replace all values for a given key when the database allows
3617 duplicate values. DB users should use DB.put(k, v) when they want
3618 to store duplicates; not DB[k] = v.

3625 characters with ASCII value less than 32. Also, it correctly quotes
3626 dots only if they occur on a single line, as opposed to the previous
3627 behavior of quoting dots if they are the second character of any
3628 line.

3974 of w# format code incorrectly truncated the length to an int, even
3975 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3976 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004006- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4007 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
