Vinay Sajip6badbe92009-01-20 22:49:13 +0000394- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000395 method on file objects with closefd=False. The file descriptor is still
396 kept open but the file object behaves like a closed file. The ``FileIO``
397 object also got a new readonly attribute ``closefd``.
398
Georg Brandlfa71a902008-12-05 09:08:28 +0000399- Issue #3689: The list reversed iterator now supports __length_hint__

605 302 conformant loader) will now work correctly in most cases (they
606 are still subject to the constraints that exist for all code running

766What's New in Python 2.6.1
767==========================
768
769*Release date: 04-Dec-2008*
770
771Core and Builtins
772-----------------
773
774- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
775 interpreter to abort ("Fatal Python error: Could not reset the stack!")
776 instead of throwing a MemoryError.
777
778- Issue #4367: Python would segfault during compiling when the unicodedata
779 module couldn't be imported and \N escapes were present.
780
781- Issue #4348: Some bytearray methods returned that didn't cause any change to
782 the bytearray, returned the same bytearray instead of a copy.
783
784- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
785
786- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
787
788- Issue #4048: The parser module now correctly validates relative imports.
789
790- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

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

957
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000958- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
959 PyString_FromFormat or PyErr_Format to display size_t values. The macro
960 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
961 ``printf`` function, whereas PyString_FromFormat has an independent

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

Antoine Pitrou0668c622008-08-26 22:42:08 +0000984 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
985 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1059 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1060 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001124What's New in Python 2.6 beta 3?
1125================================
1126
Barry Warsaw07a4a382008-08-21 01:15:08 +00001127*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001128
1129Core and Builtins
1130-----------------
1131
Guido van Rossumf8402962008-08-20 15:01:50 +00001132- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1133 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1134 extensions do not automatically benefit from the class attribute
1135 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1136 to their tp_flags field if they care. This is a backwards
1137 compatibility feature; in 3.0, all types will use the cache by
1138 default.
1139
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001140- Keyword arguments can now follow starred arguments. (``f(a, *args,
1141 keyword=23)`` is now valid syntax.)
1142
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001143- ctypes function pointers that are COM methods have a boolean True
1144 value again.
1145
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001146- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1147 by denying s# to parse objects that have a releasebuffer procedure,
1148 and introducing s*.
1149
Georg Brandl1e13ea92008-08-11 09:07:59 +00001150- Issue #3537: Fix an assertion failure when an empty but presized dict
1151 object was stored in the freelist.
1152
Mark Dickinsonb6467572008-08-04 21:30:09 +00001153- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1154 ValueError consistently across platforms.
1155
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001156- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1157 (64bit Unix, for example), unichr() would truncate its argument and return
1158 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1159
Neal Norwitze7d8be82008-07-31 17:17:14 +00001160- Apply security patches from Apple.
1161
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001162- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1163 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1164
Antoine Pitrou92f82162008-07-25 22:22:08 +00001165- Issue #1819: function calls with several named parameters are now on
1166 average 35% faster (as measured by pybench).
1167
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001168- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1169 the python debugger steps into a class statement: the free variables (local
1170 variables defined in an outer scope) would be deleted from the outer scope.
1171
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001172- Issue #2620: Overflow checking when allocating or reallocating memory
1173 was not always being done properly in some python types and extension
1174 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1175 all been updated to perform better checks and places in the code that
1176 would previously leak memory on the error path when such an allocation
1177 failed have been fixed.

1180-------
1181
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001182- Issue #3612: Added some missing basic types in ctypes.wintypes.
1183
Benjamin Petersone977ad42008-08-20 01:42:01 +00001184- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1185 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1186
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001187- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1188 version reported by these tools does not necessarily follow the python
1189 version numbering scheme, so the module is less strict when parsing it.
1190
Nick Coghlanf70385a2008-08-18 12:42:46 +00001191- Issue #2235: Added Py3k warnings for types which will become unhashable
1192 under the stricter __hash__ inheritance rules in 3.0. Several types
1193 which did not meet the rules for hash invariants and were already
1194 unhashable in 3.0 have now been explicitly flagged as unhashable in
1195 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1196 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1197
Brett Cannon88f801d2008-08-18 00:46:22 +00001198- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1199 imported into the module but exposed as part of the module's API.
1200
Brett Cannon7b96f072008-08-18 00:41:11 +00001201- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1202
Brett Cannon46225e72008-08-18 00:36:52 +00001203- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001205- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1206
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001207- Issue #3575: Incremental decoder's decode function now takes bytearray
1208 by using 's*' instead of 't#'.
1209
Jesus Cea585ad8a2009-07-02 15:37:21 +00001210- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001211 fails unicode conversion on 2nd parameter. (windows only)
1212
Facundo Batista94f243a2008-08-17 03:38:39 +00001213- Issue 2464. urllib2 now supports a malformation in the URL received
1214 in a redirect.
1215
Brett Cannonabe423e2008-08-16 21:47:07 +00001216- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001217 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001218
Facundo Batistaeb90b782008-08-16 14:44:07 +00001219- Issue #2776: fixed small issue when handling an URL with double slash
1220 after a 302 response in the case of not going through a proxy.
1221
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001222- Issue #2676: in the email package, content-type parsing was hanging on
1223 pathological input because of quadratic or exponential behaviour of a
1224 regular expression.
1225
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001226- Issue #3476: binary buffered reading through the new "io" library is now
1227 thread-safe.
1228
Brett Cannonbf3157b2008-08-14 05:00:03 +00001229- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1230 since mimetools itself is deprecated. Because modules are cached, all
1231 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1232
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001233- Issue #3134: shutil referenced undefined WindowsError symbol.
1234
Robert Schuppenies14646332008-08-10 11:01:53 +00001235- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1236 menu entries were not deleted.
1237
Brett Cannon83e81842008-08-09 23:30:55 +00001238- Copied the implementation of reduce() to _functools.reduce() to have a
1239 version that did not raise a DeprecationWarning under -3.
1240
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001241- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1242 a MemoryError rather than silently stop the iteration.
1243
Guido van Rossum59ce9012008-08-09 14:55:34 +00001244- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1245 to _sre.compile() will now be rejected. This should not affect anybody
1246 since the re.compile() function never generates invalid re-bytecode.
1247
Skip Montanaroa032bf42008-08-08 22:52:51 +00001248- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1249 upon first access it can be automatically initialized from the csv file if
1250 it wasn't initialized during instantiation.
1251
Brett Cannon3aa2a492008-08-06 22:28:09 +00001252- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1253 the reload() built-in has been removed.
1254
Brett Cannon7e30b672008-08-04 21:52:25 +00001255- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001256 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001267 asking for a specific length. This problem only affected files opened
1268 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001269

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001293- Issue #3394: zipfile.writestr sets external attributes when passed a
1294 file name rather than a ZipInfo instance, so files are extracted with
1295 mode 0600 rather than 000 under Unix.
1296
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001297- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1298 argument in python 2.5, this broke code that subclassed Popen to include its
1299 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1310 interaction with the tp_hash slot (added in 2.6b2) are now documented
1311
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001312- Issue #643841: The language reference now provides more detailed
1313 coverage of the lookup process for special methods. The disclaimers
1314 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001318What's New in Python 2.6 beta 2?
1319================================
1320
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001321*Release date: 17-Jul-2008*
1322
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001323Core and Builtins
1324-----------------
1325
Georg Brandl3e483f62008-07-16 22:57:41 +00001326- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1327 its methods now allow for items objects that can be converted to
1328 an integer using operator.index().
1329
Mark Dickinson64b7e502008-07-16 09:40:03 +00001330- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1331 produced a ValueError instead of giving the correct float.
1332
Eric Smitha5fa5a22008-07-16 00:11:49 +00001333- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1334 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1335
Mark Dickinson7103aa42008-07-15 19:08:33 +00001336- Issue #3008: the float type has a new instance method 'float.hex'
1337 and a new class method 'float.fromhex' to convert floating-point
1338 numbers to and from hexadecimal strings, respectively.
1339
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001340- Issue #2235: __hash__ is once again inherited by default. To allow
1341 collections.Hashable to remain meaningful in the presence of the
1342 default hash implementation (object.__hash__), it is now possible
1343 to explicit block inheritance of hash by setting __hash__=None at
1344 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1345 level.
1346
Nick Coghlanb028f502008-07-13 14:52:36 +00001347- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1348 the parent module cannot be found while performing an absolute import.
1349 This means that an incorrectly defined __package__ attribute will
1350 now only prevent relative imports in that module rather than causing
1351 all imports from that module to fail.
1352
Nick Coghlan14ff9942008-07-08 14:21:42 +00001353- Issue #2517: Allow unicode messages in Exceptions again by correctly
1354 bypassing the instance dictionary when looking up __unicode__ on
1355 new-style classes.
1356
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001357- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1358 set to a custom object whose write() method happens to install
1359 another file in sys.stdout.
1360
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001361- Issue #3088: Corrected a race condition in classes derived from
1362 threading.local: the first member set by a thread could be saved in
1363 another thread's dictionary.
1364
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001365- Issue #3004: Minor change to slice.indices(): the start and stop
1366 arguments are now treated identically, making the behaviour easier
1367 to describe and understand. For example, slice(None, -10,
1368 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1369 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1370 10, -1).
1371
Georg Brandl278fc502008-07-19 12:46:12 +00001372- Issue #3219: Calling a function with repeated keyword arguments,
1373 f(a=2, a=23), would not cause a syntax error. This was a regression
1374 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001375
Georg Brandl278fc502008-07-19 12:46:12 +00001376- Issue #2862: Make int and float freelist management consistent with
1377 other freelists. Changes their CompactFreeList apis into
1378 ClearFreeList apis and calls them via gc.collect().

1382
Thomas Heller57adf222008-08-14 19:10:48 +00001383- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1384 api functions without holding the GIL, which could lead to a fatal
1385 error when they failed.
1386
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001387- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1396 ForkingPickler.register() to resolve conflict with ctypes.
1397
Vinay Sajip51e65192008-07-18 09:01:10 +00001398- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001399
Thomas Heller880f5292008-07-15 19:39:38 +00001400- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1401 a valid dlerror() message.
1402
Thomas Heller2bad6572008-07-15 17:19:50 +00001403- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1404 incomplete structure was created.

1409
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001410- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001411
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001412- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1413 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001414 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001415 content-length. The problem had been corrected in the 2.4 branch, but never
1416 merged into trunk.
1417
Georg Brandle78fbcc2008-07-05 10:13:36 +00001418- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001431- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1432 handling is now the same as that of other special attributes like __name__).
1433
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001434- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00001956- Issue #2550: The approach used by client/server code for obtaining
1957 ports to listen on in network-oriented tests has been refined in an
1958 effort to facilitate running multiple instances of the entire
1959 regression test suite in parallel without issue.
1960 test_support.bind_port() has been fixed such that it will always
1961 return a unique port -- which wasn't always the case with the
1962 previous implementation, especially if socket options had been set
1963 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1964 new implementation of bind_port() will actually raise an exception
1965 if it is passed an AF_INET/SOCK_STREAM socket with either the
1966 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1967 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1968 the socket it's been passed. This currently only applies to
1969 Windows. This option prevents any other sockets from binding to the
1970 host/port we've bound to, thus removing the possibility of the
1971 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1972 when a second SOCK_STREAM socket binds and accepts to a host/port
1973 that's already been bound by another socket. The optional preferred
1974 port parameter to bind_port() has been removed. Under no
1975 circumstances should tests be hard coding ports!
1976
1977 test_support.find_unused_port() has also been introduced, which will
1978 pass a temporary socket object to bind_port() in order to obtain an
1979 unused port. The temporary socket object is then closed and
1980 deleted, and the port is returned. This method should only be used
1981 for obtaining an unused port in order to pass to an external program
1982 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1983 a parameter to a server-oriented class that doesn't give you direct
1984 access to the underlying socket used.
1985
1986 Finally, test_support.HOST has been introduced, which should be used
1987 for the host argument of any relevant socket calls (i.e. bind and
1988 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001989
1990 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001991 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2263-----------------
2264
Fred Drakea8ee94b2008-03-01 02:45:07 +00002265- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002266 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002271
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002272- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002273 issue 215555 for a discussion.
2274
Eric Smitha73fbe72008-02-23 03:09:44 +00002275- Added the future_builtins module, which contains hex() and oct().
2276 These are the PEP 3127 version of these functions, designed to be
2277 compatible with the hex() and oct() builtins from Python 3.0. They
2278 differ slightly in their output formats from the existing, unchanged
2279 Python 2.6 builtins. The expected usage of the future_builtins
2280 module is:
2281 from future_builtins import hex, oct
2282
Eric Smith7ef40bf2008-02-20 23:34:22 +00002283- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2284 exponents for exponents with absolute value < 100. Follows C99
2285 standard. This is a change on Windows, which would use 3 digits.
2286 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2287 so that any alterations it does to the resulting string will be
2288 available in stringlib/formatter.h (for float.__format__).
2289
Eric Smith5a3c1352008-02-19 13:21:56 +00002290- Implemented PEP 3101, Advanced String Formatting. This adds a new
2291 builtin format(); a format() method for str and unicode; a
2292 __format__() method to object, str, unicode, int, long, float, and
2293 datetime; the class string.Formatter; and the C API
2294 PyObject_Format().
2295
Georg Brandl3ee81df2008-05-17 18:14:43 +00002296- Fixed several potential crashes, all caused by specially crafted
2297 __del__ methods exploiting objects in temporarily inconsistent
2298 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002299
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002300- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002301 prevent a possible crash: an Abstract Base Class would try to access
2302 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002307- Clear all free lists during a gc.collect() of the highest generation
2308 in order to allow pymalloc to free more arenas. Python may give back
2309 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002310
Georg Brandl3ee81df2008-05-17 18:14:43 +00002311- Issue #2045: Fix an infinite recursion triggered when printing a
2312 subclass of collections.defaultdict, if its default_factory is set
2313 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002314
Christian Heimesf75dbef2008-02-08 00:11:31 +00002315- Fixed a minor memory leak in dictobject.c. The content of the free
2316 list was not freed on interpreter shutdown.
2317
Georg Brandl3ee81df2008-05-17 18:14:43 +00002318- Limit free list of method and builtin function objects to 256
2319 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002321- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2322 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002323 to compact the internal free lists of pre-allocted ints and floats.
2324
Georg Brandl3ee81df2008-05-17 18:14:43 +00002325- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2326 calls. Python expected the return type int but the fork familie
2327 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002328

Georg Brandl3ee81df2008-05-17 18:14:43 +00002341- Patch #1473257: generator objects gain a gi_code attribute. This is
2342 the same object as the func_code attribute of the function that
2343 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002344
Georg Brandl3ee81df2008-05-17 18:14:43 +00002345- Issue #1920: "while 0" statements were completely removed by the
2346 compiler, even in the presence of an "else" clause, which is
2347 supposed to be run when the condition is false. Now the compiler
2348 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002349

Georg Brandl6caad7d2008-01-26 14:19:22 +00002367- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002368 added.
2369
Christian Heimesc94e2b52008-01-14 04:13:37 +00002370- sys.float_info / PyFloat_GetInfo: The floating point information

Georg Brandl3ee81df2008-05-17 18:14:43 +00002376- Objects/structseq.c: Implemented new structseq representation. The
2377 patch makes structseqs (e.g. the return value of os.stat) more
2378 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002379
Georg Brandl3ee81df2008-05-17 18:14:43 +00002380- Patch #1700288: added a type attribute cache that caches method
2381 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002382
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002383- Bug #1776: __import__() no longer accepts filenames on any platform.
2384 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00002386- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2387
Georg Brandl3ee81df2008-05-17 18:14:43 +00002388- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2389 envvar and sys.dont_write_bytecode attribute. All these can be set
2390 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002391
Georg Brandl3ee81df2008-05-17 18:14:43 +00002392- Improve some exception messages when Windows fails to load an
2393 extension module. Now we get for example '%1 is not a valid Win32
2394 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002395

Christian Heimes0a8143f2007-12-18 23:22:54 +00002401- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002402 and INF. float("nan"), float("inf") and float("-inf") now work on
2403 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002405- Compiler now generates simpler and faster code for dictionary
2406 literals. The oparg for BUILD_MAP now indicates an estimated
2407 dictionary size. There is a new opcode, STORE_MAP, for adding
2408 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002437- Patch #1739468: Directories and zipfiles containing a __main__.py
2438 file can now be directly executed by passing their name to the
2439 interpreter. The directory/zipfile is automatically inserted as the
2440 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002442- Issue #1265: Fix a problem with sys.settrace, if the tracing
2443 function uses a generator expression when at the same time the
2444 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002445
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002446- sets and frozensets now have an isdisjoint() method.

2449
Neal Norwitz44f326e2007-10-05 05:29:17 +00002450- Fix warnings found by the new version of the Coverity checker.
2451
Georg Brandl3ee81df2008-05-17 18:14:43 +00002452- The enumerate() builtin function is no longer bounded to sequences
2453 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2454 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002455
Georg Brandl3ee81df2008-05-17 18:14:43 +00002456- Issue #1686386: Tuple's tp_repr did not take into account the
2457 possibility of having a self-referential tuple, which is possible
2458 from C code. Nor did object's tp_str consider that a type's tp_str
2459 could do something that could lead to an inifinite recursion.
2460 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2461 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002462
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463- Issue #1164: It was possible to trigger deadlock when using the
2464 'print' statement to write to a file since the GIL was not released
2465 as needed. Now PyObject_Print() does the right thing along with
2466 various tp_print implementations of the built-in types and those in
2467 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002468
Georg Brandl3ee81df2008-05-17 18:14:43 +00002469- Issue #1147: Exceptions were directly allowing string exceptions in

2471 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00002475
Brett Cannon1e534b52007-09-07 04:18:30 +00002476- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002477 PyObject_Call() never calling back out to Python code to trigger
2478 recursion depth updates/checks. Required the creation of a static
2479 RuntimeError instance in case normalizing an exception put the
2480 recursion check value past its limit. Fixes crashers
2481 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002482

Neal Norwitz0ac60192007-05-27 04:08:54 +00002496- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002497 __*__ attributes. (Some already existed, e.g., __doc__ and
2498 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002499
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002500- Add -3 option to the interpreter to warn about features that are
2501 deprecated and will be changed/removed in Python 3.0.
2502
Georg Brandl2134e752007-05-21 20:34:16 +00002503- Patch #1686487: you can now pass any mapping after '**' in function
2504 calls.
2505
Collin Winter62903052007-05-18 23:11:24 +00002506- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002507 "except E as target:". This is to provide forwards compatibility
2508 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002509
Brett Cannon229cee22007-05-05 01:34:02 +00002510- Deprecate BaseException.message as per PEP 352.

2514
Vinay Sajip8549ce32007-05-06 17:53:37 +00002515- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002516 setting a plain string, ie don't expand to single letter identifiers.
2517
Raymond Hettinger13936692007-04-11 18:40:58 +00002518- Request #1191699: Slices can now be pickled.
2519
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002520- Request #1193128: str.translate() now allows a None argument for

2522 remaining characters.
2523
Georg Brandl5cb76c12007-03-21 09:00:39 +00002524- Patch #1682205: a TypeError while unpacking an iterable is no longer
2525 masked by a generic one with the message "unpack non-sequence".
2526
Neal Norwitzaa754b72007-03-21 06:39:48 +00002527- Remove unused file Python/fmod.c.
2528
Guido van Rossum143b5642007-03-23 04:58:42 +00002529- Bug #1683368: The object.__init__() and object.__new__() methods are
2530 now stricter in rejecting excess arguments. The only time when
2531 either allows excess arguments is when it is not overridden and the
2532 other one is. For backwards compatibility, when both are
2533 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002534 warning later). Also, type.__init__() insists on the same signature
2535 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002536
Georg Brandl3ee81df2008-05-17 18:14:43 +00002537- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2538 object to complex using its __complex__() method before falling back
2539 to the __float__() method. Therefore, the functions in the cmath
2540 module now can operate on objects that define a __complex__()
2541 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Patch #1623563: allow __class__ assignment for classes with
2544 __slots__. The old and the new class are still required to have the
2545 same slot names.

2558
Georg Brandl7b9c5552007-03-12 14:30:05 +00002559- Bug #1678647: write a newline after printing an exception in any
2560 case, even when converting the value to a string failed.
2561
Georg Brandl871f1bc2007-03-12 13:17:36 +00002562- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563 its argument, if it exists. If not, it will work like before. This
2564 allows customizing the output of dir() in the presence of a
2565 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00002567- Patch #922167: Python no longer segfaults when faced with infinitely
2568 self-recursive reload() calls (as reported by bug #742342).
2569

2574 parthensized forms. This means complex(repr(x)) now works instead of
2575 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002576
Georg Brandlaa2321b2007-03-07 00:40:28 +00002577- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002578 makes the filenames the warning module prints much more sensible
2579 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002580

Georg Brandl0fca97a2007-03-05 22:28:08 +00002592- Patch #1674228: when assigning a slice (old-style), check for the
2593 sq_ass_slice instead of the sq_slice slot.
2594
Georg Brandl3ee81df2008-05-17 18:14:43 +00002595- When printing an unraisable error, don't print exceptions. before
2596 the name. This duplicates the behavior whening normally printing
2597 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003130 AttributeError instead of an IOError when the server's response
3131 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003132

Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- Patch #1429539: pdb now correctly initializes the __main__ module
3138 for the debugged script, which means that imports from __main__ work

3147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Patch #1530482: add pydoc.render_doc() which returns the

3163
Georg Brandl92a6bae2007-03-13 17:43:32 +00003164- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003165 are set for invalid interpolation sequences that would lead to
3166 errors on reading back those values.

3222 TestCase and TestSuite subclasses (not instances) are no longer
3223 accepted in TestSuite.addTest(). This should cause no
3224 incompatibility since it never made sense with ordinary subclasses
3225 -- the failure just occurred later, with a more cumbersome
3226 exception.

3597 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3598 silently miscode subclasses of those types. Now, it raises a
3599 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003614- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003615 time so that opening a database previously created with the DB_DUP
3616 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3617 opens. Specifically: dictionary assignment to a DB object will
3618 replace all values for a given key when the database allows
3619 duplicate values. DB users should use DB.put(k, v) when they want
3620 to store duplicates; not DB[k] = v.

3627 characters with ASCII value less than 32. Also, it correctly quotes
3628 dots only if they occur on a single line, as opposed to the previous
3629 behavior of quoting dots if they are the second character of any
3630 line.

3976 of w# format code incorrectly truncated the length to an int, even
3977 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3978 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004008- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4009 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
