84
Tarek Ziadé06426fc2010-01-11 22:54:57 +000085- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

95

97 renaming of `cPickle` to `pickle`. The warning was annoying since there's
98 no alternative to cPickle if you care about performance. Patch by Florent
99 Xicluna.
100
Antoine Pitrou8dba7272010-01-07 18:04:12 +0000101- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000137- Issue #7318: multiprocessing now uses a timeout when it fails to establish

158 reading from stdin so that existing input does not confuse it and
159 lead to incorrect entry or an IOError. It also properly flushes it
160 afterwards to avoid the terminal echoing the input afterwards on
161 OSes such as Solaris.
162
Raymond Hettinger80d49b32009-11-01 08:53:21 +0000163- Issue #7244: itertools.izip_longest() no longer ignores exceptions

170
R. David Murray7034db32009-10-27 23:39:06 +0000171- Issue #7082: When falling back to the MIME 'name' parameter, the
172 correct place to look for it is the Content-Type header.
173
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000174- Issue #7099: Decimal.is_normal now returns True for numbers with exponent

Vinay Sajip6badbe92009-01-20 22:49:13 +0000718- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000719 method on file objects with closefd=False. The file descriptor is still
720 kept open but the file object behaves like a closed file. The ``FileIO``
721 object also got a new readonly attribute ``closefd``.
722
Georg Brandlfa71a902008-12-05 09:08:28 +0000723- Issue #3689: The list reversed iterator now supports __length_hint__

932- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
933 302 conformant loader) will now work correctly in most cases (they
934 are still subject to the constraints that exist for all code running
935 from inside a module loaded via a PEP 302 loader and attempting to

1095==========================
1096
1097*Release date: 04-Dec-2008*
1098
1099Core and Builtins
1100-----------------
1101
1102- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1103 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1104 instead of throwing a MemoryError.
1105
1106- Issue #4367: Python would segfault during compiling when the unicodedata
1107 module couldn't be imported and \N escapes were present.
1108
1109- Issue #4348: Some bytearray methods returned that didn't cause any change to
1110 the bytearray, returned the same bytearray instead of a copy.
1111
1112- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1113
1114- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1115
1116- Issue #4048: The parser module now correctly validates relative imports.

1125 __future__ import didn't work.
1126
1127- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1128 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1129 really executed because I cannot move to such directory on win2k)
1130
1131- Issue #4069: When set.remove(element) is used with a set element, the element
1132 is temporarily replaced with an equivalent frozenset. But the eventual
1133 KeyError would always report the empty frozenset([]) as the missing key. Now
1134 it correctly refers to the initial element.
1135

1137 again.

1288 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1289 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001309 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001311- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001312 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1313 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1314 when given a tuple of classes as second argument, were looking up
1315 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1316 type object.
1317
Neal Norwitz18aa3882008-08-24 05:04:52 +00001318- Fix crashes on memory allocation failure found with failmalloc.

1334
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001335- Issue #1204: The configure script now tests for additional libraries
1336 that may be required when linking against readline. This fixes issues
1337 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1387 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1388 for catch_warnings() also led to an improvement in the raising of a
1389 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001411- Issue #2975: When compiling several extension modules with Visual Studio 2008
1412 from the same python interpreter, some environment variables would grow
1413 without limit.
1414

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001452What's New in Python 2.6 beta 3?
1453================================
1454
Barry Warsaw07a4a382008-08-21 01:15:08 +00001455*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001456
1457Core and Builtins
1458-----------------
1459
Guido van Rossumf8402962008-08-20 15:01:50 +00001460- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1461 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1462 extensions do not automatically benefit from the class attribute
1463 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1464 to their tp_flags field if they care. This is a backwards
1465 compatibility feature; in 3.0, all types will use the cache by
1466 default.
1467
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001468- Keyword arguments can now follow starred arguments. (``f(a, *args,
1469 keyword=23)`` is now valid syntax.)
1470
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001471- ctypes function pointers that are COM methods have a boolean True
1472 value again.
1473
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001474- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1475 by denying s# to parse objects that have a releasebuffer procedure,
1476 and introducing s*.
1477
Georg Brandl1e13ea92008-08-11 09:07:59 +00001478- Issue #3537: Fix an assertion failure when an empty but presized dict
1479 object was stored in the freelist.
1480
Mark Dickinsonb6467572008-08-04 21:30:09 +00001481- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1482 ValueError consistently across platforms.
1483
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001484- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1485 (64bit Unix, for example), unichr() would truncate its argument and return
1486 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1487
Neal Norwitze7d8be82008-07-31 17:17:14 +00001488- Apply security patches from Apple.
1489
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001490- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1491 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1492
Antoine Pitrou92f82162008-07-25 22:22:08 +00001493- Issue #1819: function calls with several named parameters are now on
1494 average 35% faster (as measured by pybench).
1495
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001496- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1497 the python debugger steps into a class statement: the free variables (local
1498 variables defined in an outer scope) would be deleted from the outer scope.
1499
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001500- Issue #2620: Overflow checking when allocating or reallocating memory
1501 was not always being done properly in some python types and extension
1502 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1503 all been updated to perform better checks and places in the code that
1504 would previously leak memory on the error path when such an allocation
1505 failed have been fixed.

1509
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001510- Issue #3612: Added some missing basic types in ctypes.wintypes.
1511
Benjamin Petersone977ad42008-08-20 01:42:01 +00001512- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1513 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1514
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001515- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1516 version reported by these tools does not necessarily follow the python
1517 version numbering scheme, so the module is less strict when parsing it.
1518
Nick Coghlanf70385a2008-08-18 12:42:46 +00001519- Issue #2235: Added Py3k warnings for types which will become unhashable
1520 under the stricter __hash__ inheritance rules in 3.0. Several types
1521 which did not meet the rules for hash invariants and were already
1522 unhashable in 3.0 have now been explicitly flagged as unhashable in
1523 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1524 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1525
Brett Cannon88f801d2008-08-18 00:46:22 +00001526- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1527 imported into the module but exposed as part of the module's API.
1528
Brett Cannon7b96f072008-08-18 00:41:11 +00001529- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1530
Brett Cannon46225e72008-08-18 00:36:52 +00001531- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001533- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1534
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001535- Issue #3575: Incremental decoder's decode function now takes bytearray
1536 by using 's*' instead of 't#'.
1537
Jesus Cea585ad8a2009-07-02 15:37:21 +00001538- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001539 fails unicode conversion on 2nd parameter. (windows only)
1540
Facundo Batista94f243a2008-08-17 03:38:39 +00001541- Issue 2464. urllib2 now supports a malformation in the URL received
1542 in a redirect.
1543
Brett Cannonabe423e2008-08-16 21:47:07 +00001544- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001545 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001546
Facundo Batistaeb90b782008-08-16 14:44:07 +00001547- Issue #2776: fixed small issue when handling an URL with double slash
1548 after a 302 response in the case of not going through a proxy.
1549
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001550- Issue #2676: in the email package, content-type parsing was hanging on
1551 pathological input because of quadratic or exponential behaviour of a
1552 regular expression.
1553
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001554- Issue #3476: binary buffered reading through the new "io" library is now
1555 thread-safe.
1556
Brett Cannonbf3157b2008-08-14 05:00:03 +00001557- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1558 since mimetools itself is deprecated. Because modules are cached, all
1559 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1560
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001561- Issue #3134: shutil referenced undefined WindowsError symbol.
1562
Robert Schuppenies14646332008-08-10 11:01:53 +00001563- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1564 menu entries were not deleted.
1565
Brett Cannon83e81842008-08-09 23:30:55 +00001566- Copied the implementation of reduce() to _functools.reduce() to have a
1567 version that did not raise a DeprecationWarning under -3.
1568
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001569- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1570 a MemoryError rather than silently stop the iteration.
1571
Guido van Rossum59ce9012008-08-09 14:55:34 +00001572- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1573 to _sre.compile() will now be rejected. This should not affect anybody
1574 since the re.compile() function never generates invalid re-bytecode.
1575
Skip Montanaroa032bf42008-08-08 22:52:51 +00001576- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1577 upon first access it can be automatically initialized from the csv file if
1578 it wasn't initialized during instantiation.
1579
Brett Cannon3aa2a492008-08-06 22:28:09 +00001580- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1581 the reload() built-in has been removed.
1582
Brett Cannon7e30b672008-08-04 21:52:25 +00001583- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001584 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1648
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001649*Release date: 17-Jul-2008*

1652-----------------
1653
Georg Brandl3e483f62008-07-16 22:57:41 +00001654- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1655 its methods now allow for items objects that can be converted to
1656 an integer using operator.index().
1657
Mark Dickinson64b7e502008-07-16 09:40:03 +00001658- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1659 produced a ValueError instead of giving the correct float.
1660
Eric Smitha5fa5a22008-07-16 00:11:49 +00001661- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1662 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1663
Mark Dickinson7103aa42008-07-15 19:08:33 +00001664- Issue #3008: the float type has a new instance method 'float.hex'
1665 and a new class method 'float.fromhex' to convert floating-point
1666 numbers to and from hexadecimal strings, respectively.
1667
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001668- Issue #2235: __hash__ is once again inherited by default. To allow
1669 collections.Hashable to remain meaningful in the presence of the
1670 default hash implementation (object.__hash__), it is now possible
1671 to explicit block inheritance of hash by setting __hash__=None at
1672 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1673 level.
1674
Nick Coghlanb028f502008-07-13 14:52:36 +00001675- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1676 the parent module cannot be found while performing an absolute import.
1677 This means that an incorrectly defined __package__ attribute will
1678 now only prevent relative imports in that module rather than causing
1679 all imports from that module to fail.
1680
Nick Coghlan14ff9942008-07-08 14:21:42 +00001681- Issue #2517: Allow unicode messages in Exceptions again by correctly

1691 another thread's dictionary.
1692
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001693- Issue #3004: Minor change to slice.indices(): the start and stop
1694 arguments are now treated identically, making the behaviour easier
1695 to describe and understand. For example, slice(None, -10,
1696 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1697 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1698 10, -1).
1699
Georg Brandl278fc502008-07-19 12:46:12 +00001700- Issue #3219: Calling a function with repeated keyword arguments,
1701 f(a=2, a=23), would not cause a syntax error. This was a regression
1702 from 2.4 caused by the switch to the new compiler.

1705 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001740- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1741 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001742 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001743 content-length. The problem had been corrected in the 2.4 branch, but never
1744 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001759- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1760 handling is now the same as that of other special attributes like __name__).

2169
Georg Brandl74a1dea2008-05-28 11:21:39 +00002170- Add ``PyType_Modified()`` as a public API to clear the type cache.
2171
2172- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002173
2174- The PyString functions have been renamed to PyBytes. A batch of
2175 defines were added so that the linker still sees the original
2176 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002214- Issue #1631171: Re-implement the 'warnings' module in C (the
2215 original Python code has been kept as backup). This will allow for
2216 using the 'warning's machinery in such places as the parser where
2217 use of pure Python code is not possible. Both the ``showarning()``
2218 and ``formatwarning()`` gain an optional 'line' argument which is
2219 not called by default for backwards-compatibility reasons. Setting
2220 ``warnings.showwarning()`` to an implementation that lacks support
2221 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002246- The getpass module has been improved on Unix. It now uses /dev/tty
2247 by default and uses stderr instead of stdout. A GetPassWarning is
2248 issued when input echo cannot be controlled.

2260 implementation detail of the public ``types`` module, has been
2261 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00002262
Georg Brandl3ee81df2008-05-17 18:14:43 +00002263- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002264 extension modules between 32 and 64 bit platforms. See the distutls

2268 threads at once without fear of crashing the Python interpreter. If
2269 file.close() is called while an object is in use by another thread
2270 an IOError exception will be raised and the file will not be closed.
2271
Thomas Hellerf7906482008-04-04 19:43:25 +00002272- The bundled libffi copy is now in sync with the recently released

2277 so the controlled environment will more closely mirror the typical
2278 script environment. This supports setup.py scripts that refer to
2279 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002284- Issue #2550: The approach used by client/server code for obtaining
2285 ports to listen on in network-oriented tests has been refined in an
2286 effort to facilitate running multiple instances of the entire
2287 regression test suite in parallel without issue.
2288 test_support.bind_port() has been fixed such that it will always
2289 return a unique port -- which wasn't always the case with the
2290 previous implementation, especially if socket options had been set
2291 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2292 new implementation of bind_port() will actually raise an exception
2293 if it is passed an AF_INET/SOCK_STREAM socket with either the
2294 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2295 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2296 the socket it's been passed. This currently only applies to
2297 Windows. This option prevents any other sockets from binding to the
2298 host/port we've bound to, thus removing the possibility of the
2299 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2300 when a second SOCK_STREAM socket binds and accepts to a host/port
2301 that's already been bound by another socket. The optional preferred
2302 port parameter to bind_port() has been removed. Under no
2303 circumstances should tests be hard coding ports!
2304
2305 test_support.find_unused_port() has also been introduced, which will
2306 pass a temporary socket object to bind_port() in order to obtain an
2307 unused port. The temporary socket object is then closed and
2308 deleted, and the port is returned. This method should only be used
2309 for obtaining an unused port in order to pass to an external program
2310 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2311 a parameter to a server-oriented class that doesn't give you direct
2312 access to the underlying socket used.
2313
2314 Finally, test_support.HOST has been introduced, which should be used
2315 for the host argument of any relevant socket calls (i.e. bind and
2316 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002317
2318 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002319 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002320 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2321 test_asynchat and test_socket_ssl.
2322
Georg Brandl3ee81df2008-05-17 18:14:43 +00002323 It is now possible for multiple instances of the regression test
2324 suite to run in parallel without issue.

2592
Fred Drakea8ee94b2008-03-01 02:45:07 +00002593- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002594 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002599
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002600- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002601 issue 215555 for a discussion.
2602
Eric Smitha73fbe72008-02-23 03:09:44 +00002603- Added the future_builtins module, which contains hex() and oct().
2604 These are the PEP 3127 version of these functions, designed to be
2605 compatible with the hex() and oct() builtins from Python 3.0. They
2606 differ slightly in their output formats from the existing, unchanged
2607 Python 2.6 builtins. The expected usage of the future_builtins
2608 module is:
2609 from future_builtins import hex, oct
2610
Eric Smith7ef40bf2008-02-20 23:34:22 +00002611- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2612 exponents for exponents with absolute value < 100. Follows C99
2613 standard. This is a change on Windows, which would use 3 digits.
2614 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2615 so that any alterations it does to the resulting string will be
2616 available in stringlib/formatter.h (for float.__format__).
2617
Eric Smith5a3c1352008-02-19 13:21:56 +00002618- Implemented PEP 3101, Advanced String Formatting. This adds a new
2619 builtin format(); a format() method for str and unicode; a
2620 __format__() method to object, str, unicode, int, long, float, and
2621 datetime; the class string.Formatter; and the C API
2622 PyObject_Format().
2623
Georg Brandl3ee81df2008-05-17 18:14:43 +00002624- Fixed several potential crashes, all caused by specially crafted
2625 __del__ methods exploiting objects in temporarily inconsistent
2626 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002627
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002628- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002629 prevent a possible crash: an Abstract Base Class would try to access
2630 a slot on a registered virtual subclass.

2636 in order to allow pymalloc to free more arenas. Python may give back
2637 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002638
Georg Brandl3ee81df2008-05-17 18:14:43 +00002639- Issue #2045: Fix an infinite recursion triggered when printing a
2640 subclass of collections.defaultdict, if its default_factory is set
2641 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002642
Christian Heimesf75dbef2008-02-08 00:11:31 +00002643- Fixed a minor memory leak in dictobject.c. The content of the free
2644 list was not freed on interpreter shutdown.
2645
Georg Brandl3ee81df2008-05-17 18:14:43 +00002646- Limit free list of method and builtin function objects to 256
2647 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002649- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2650 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002651 to compact the internal free lists of pre-allocted ints and floats.
2652
Georg Brandl3ee81df2008-05-17 18:14:43 +00002653- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2654 calls. Python expected the return type int but the fork familie
2655 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002656

Georg Brandl3ee81df2008-05-17 18:14:43 +00002669- Patch #1473257: generator objects gain a gi_code attribute. This is
2670 the same object as the func_code attribute of the function that
2671 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002672
Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Issue #1920: "while 0" statements were completely removed by the
2674 compiler, even in the presence of an "else" clause, which is
2675 supposed to be run when the condition is false. Now the compiler
2676 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002677

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002682- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002683 suppressed while an extension is loaded by calling SetErrorMode in
2684 dynload_win.c. The error is still reported properly.
2685
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002687 several extension methods and modules do not work without unicode
2688 support.
2689
Georg Brandl26543b12008-01-21 18:36:51 +00002690- Issue #1882: when compiling code from a string, encoding cookies in the
2691 second line of code were not always recognized correctly.
2692
Georg Brandl14404b62008-01-19 19:27:05 +00002693- Issue #1679: "0x" was taken as a valid integer literal.
2694
Georg Brandl6caad7d2008-01-26 14:19:22 +00002695- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002696 added.
2697
Christian Heimesc94e2b52008-01-14 04:13:37 +00002698- sys.float_info / PyFloat_GetInfo: The floating point information
2699 object was converted from a dict to a specialized structseq object.
2700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Patch #1816: Added sys.flags structseq. It exposes the status of
2702 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002703
Georg Brandl3ee81df2008-05-17 18:14:43 +00002704- Objects/structseq.c: Implemented new structseq representation. The
2705 patch makes structseqs (e.g. the return value of os.stat) more
2706 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002707
Georg Brandl3ee81df2008-05-17 18:14:43 +00002708- Patch #1700288: added a type attribute cache that caches method
2709 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002710
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002711- Bug #1776: __import__() no longer accepts filenames on any platform.
2712 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002713
Georg Brandlaed6c662008-01-07 17:25:53 +00002714- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2715
Georg Brandl3ee81df2008-05-17 18:14:43 +00002716- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2717 envvar and sys.dont_write_bytecode attribute. All these can be set
2718 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002719
Georg Brandl3ee81df2008-05-17 18:14:43 +00002720- Improve some exception messages when Windows fails to load an
2721 extension module. Now we get for example '%1 is not a valid Win32
2722 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002723
Georg Brandl3ee81df2008-05-17 18:14:43 +00002724- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002726- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2727 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002728
Christian Heimes0a8143f2007-12-18 23:22:54 +00002729- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002730 and INF. float("nan"), float("inf") and float("-inf") now work on
2731 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002732
Georg Brandl3ee81df2008-05-17 18:14:43 +00002733- Compiler now generates simpler and faster code for dictionary
2734 literals. The oparg for BUILD_MAP now indicates an estimated
2735 dictionary size. There is a new opcode, STORE_MAP, for adding
2736 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002737
Georg Brandl3ee81df2008-05-17 18:14:43 +00002738- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00002739
Georg Brandl3ee81df2008-05-17 18:14:43 +00002740- Issue #1620: New property decorator syntax was modifying the
2741 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002742
Georg Brandl3ee81df2008-05-17 18:14:43 +00002743- Issue #1538: Avoid copying string in split/rsplit if the split char
2744 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002745
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002746- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002747 SystemError.
2748
Nick Coghlanef01d822007-12-03 12:55:17 +00002749- PEP 366: Allow explicit relative imports when executing modules

2754 running, and if the deallocation of its frames somehow calls the
2755 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002756

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002760 attribute of an empty cell object.
2761
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762- Issue #1460: The utf-7 incremental decoder did not accept truncated
2763 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002764
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765- Patch #1739468: Directories and zipfiles containing a __main__.py
2766 file can now be directly executed by passing their name to the
2767 interpreter. The directory/zipfile is automatically inserted as the
2768 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002769
Georg Brandl3ee81df2008-05-17 18:14:43 +00002770- Issue #1265: Fix a problem with sys.settrace, if the tracing
2771 function uses a generator expression when at the same time the
2772 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002773
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002774- sets and frozensets now have an isdisjoint() method.
2775
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002776- optimize the performance of builtin.sum().
2777
Neal Norwitz44f326e2007-10-05 05:29:17 +00002778- Fix warnings found by the new version of the Coverity checker.
2779
Georg Brandl3ee81df2008-05-17 18:14:43 +00002780- The enumerate() builtin function is no longer bounded to sequences
2781 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2782 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002783
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784- Issue #1686386: Tuple's tp_repr did not take into account the
2785 possibility of having a self-referential tuple, which is possible
2786 from C code. Nor did object's tp_str consider that a type's tp_str
2787 could do something that could lead to an inifinite recursion.
2788 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2789 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002790
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Issue #1164: It was possible to trigger deadlock when using the
2792 'print' statement to write to a file since the GIL was not released
2793 as needed. Now PyObject_Print() does the right thing along with
2794 various tp_print implementations of the built-in types and those in
2795 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002796
Georg Brandl3ee81df2008-05-17 18:14:43 +00002797- Issue #1147: Exceptions were directly allowing string exceptions in
2798 their throw() method even though string exceptions no longer
2799 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002800
Georg Brandl3ee81df2008-05-17 18:14:43 +00002801- Issue #1096: Prevent a segfault from getting the repr of a very
2802 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002803
Brett Cannon1e534b52007-09-07 04:18:30 +00002804- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805 PyObject_Call() never calling back out to Python code to trigger
2806 recursion depth updates/checks. Required the creation of a static
2807 RuntimeError instance in case normalizing an exception put the
2808 recursion check value past its limit. Fixes crashers
2809 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002810
Georg Brandl3ee81df2008-05-17 18:14:43 +00002811- Patch #1031213: Decode source line in SyntaxErrors back to its
2812 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00002813
Georg Brandl7c3b50d2007-07-12 08:38:00 +00002814- Patch #1673759: add a missing overflow check when formatting floats
2815 with %G.
2816
Georg Brandl3ee81df2008-05-17 18:14:43 +00002817- Prevent expandtabs() on string and unicode objects from causing a
2818 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002819

Martin v. Löwisda587ab2007-06-08 17:29:20 +00002821
Georg Brandl3ee81df2008-05-17 18:14:43 +00002822- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00002823
Neal Norwitz0ac60192007-05-27 04:08:54 +00002824- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002825 __*__ attributes. (Some already existed, e.g., __doc__ and
2826 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002827
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002828- Add -3 option to the interpreter to warn about features that are
2829 deprecated and will be changed/removed in Python 3.0.
2830
Georg Brandl2134e752007-05-21 20:34:16 +00002831- Patch #1686487: you can now pass any mapping after '**' in function
2832 calls.
2833
Collin Winter62903052007-05-18 23:11:24 +00002834- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835 "except E as target:". This is to provide forwards compatibility
2836 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002837
Brett Cannon229cee22007-05-05 01:34:02 +00002838- Deprecate BaseException.message as per PEP 352.
2839
Georg Brandl3ee81df2008-05-17 18:14:43 +00002840- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002841 inherited from a builtin base.
2842
Vinay Sajip8549ce32007-05-06 17:53:37 +00002843- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002844 setting a plain string, ie don't expand to single letter identifiers.
2845
Raymond Hettinger13936692007-04-11 18:40:58 +00002846- Request #1191699: Slices can now be pickled.
2847
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002848- Request #1193128: str.translate() now allows a None argument for
2849 translations that only remove characters without re-mapping the
2850 remaining characters.
2851
Georg Brandl5cb76c12007-03-21 09:00:39 +00002852- Patch #1682205: a TypeError while unpacking an iterable is no longer
2853 masked by a generic one with the message "unpack non-sequence".
2854
Neal Norwitzaa754b72007-03-21 06:39:48 +00002855- Remove unused file Python/fmod.c.
2856
Guido van Rossum143b5642007-03-23 04:58:42 +00002857- Bug #1683368: The object.__init__() and object.__new__() methods are
2858 now stricter in rejecting excess arguments. The only time when
2859 either allows excess arguments is when it is not overridden and the
2860 other one is. For backwards compatibility, when both are
2861 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002862 warning later). Also, type.__init__() insists on the same signature
2863 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002864
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2866 object to complex using its __complex__() method before falling back
2867 to the __float__() method. Therefore, the functions in the cmath
2868 module now can operate on objects that define a __complex__()
2869 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002870
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Patch #1623563: allow __class__ assignment for classes with
2872 __slots__. The old and the new class are still required to have the
2873 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002874
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875- Patch #1642547: Fix an error/crash when encountering syntax errors
2876 in complex if statements.
Collin Winter77c67bd2007-03-16 04:11:30 +00002877
Georg Brandl3ee81df2008-05-17 18:14:43 +00002878- Patch #1462488: Python no longer segfaults when
2879 ``object.__reduce_ex__()`` is called with an object that is faking
2880 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002881
Georg Brandl3ee81df2008-05-17 18:14:43 +00002882- Patch #1680015: Don't modify __slots__ tuple if it contains an
2883 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00002884
Georg Brandl5240d742007-03-13 20:46:32 +00002885- Patch #1444529: the builtin compile() now accepts keyword arguments.
2886
Georg Brandl7b9c5552007-03-12 14:30:05 +00002887- Bug #1678647: write a newline after printing an exception in any
2888 case, even when converting the value to a string failed.
2889
Georg Brandl871f1bc2007-03-12 13:17:36 +00002890- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002891 its argument, if it exists. If not, it will work like before. This
2892 allows customizing the output of dir() in the presence of a
2893 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002894
Collin Winter276887b2007-03-12 16:11:39 +00002895- Patch #922167: Python no longer segfaults when faced with infinitely
2896 self-recursive reload() calls (as reported by bug #742342).
2897
Georg Brandl3ee81df2008-05-17 18:14:43 +00002898- Patch #1675981: remove unreachable code from ``type.__new__()``
2899 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00002900
Georg Brandl3ee81df2008-05-17 18:14:43 +00002901- Patch #1491866: change the complex() constructor to allow
2902 parthensized forms. This means complex(repr(x)) now works instead of
2903 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002904
Georg Brandlaa2321b2007-03-07 00:40:28 +00002905- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002906 makes the filenames the warning module prints much more sensible
2907 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002908
Georg Brandl49aafc92007-03-07 00:34:46 +00002909- Variant of patch #697613: don't exit the interpreter on a SystemExit
2910 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002911 variable is given, but break into the interactive interpreter just
2912 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00002913
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914- Patch #1638879: don't accept strings with embedded NUL bytes in
2915 long().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- Bug #1674503: close the file opened by execfile() in an error
2918 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002919
Georg Brandl0fca97a2007-03-05 22:28:08 +00002920- Patch #1674228: when assigning a slice (old-style), check for the

3413 (as opposed to the command line) will now write file names ending in
3414 ".cpp" too.
3415
Facundo Batistad918a652007-04-24 13:54:38 +00003416- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003417 the client's request was successfully received, understood, and
3418 accepted. Now in these cases no error is raised in urllib (issue
3419 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003420

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003427- Added a timeout parameter to the constructor of other protocols
3428 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3429 work started with create_connection() and timeout in httplib, and
3430 closes patch #723312.
3431
Vinay Sajip8549ce32007-05-06 17:53:37 +00003432- Patch #1676823: Added create_connection() to socket.py, which may be
3433 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003434 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003435
Martin v. Löwis0af33882007-03-23 13:27:15 +00003436- Bug #978833: Revert r50844, as it broke _socketobject.dup.

3456
Georg Brandlf66b6032007-03-14 08:27:52 +00003457- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458 AttributeError instead of an IOError when the server's response
3459 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003460
Georg Brandl3ee81df2008-05-17 18:14:43 +00003461- Patch #957650: "%var%" environment variable references are now
3462 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00003464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Patch #1429539: pdb now correctly initializes the __main__ module
3466 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003467 correctly now.
3468
Georg Brandlbad6f192007-03-13 21:32:56 +00003469- The nonobvious commands.getstatus() function is now deprecated.

3475
Georg Brandl3ee81df2008-05-17 18:14:43 +00003476- Patch #1530482: add pydoc.render_doc() which returns the
3477 documentation for a thing instead of paging it to stdout, which
3478 pydoc.doc() does.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- Patch #1533909: the timeit module now accepts callables in addition

Georg Brandl3ee81df2008-05-17 18:14:43 +00003485- Patch #1537850: tempfile.NamedTemporaryFile now has a "delete"
3486 parameter which can be set to False to prevent the default
3487 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00003489- Patch #1581073: add a flag to textwrap that prevents the dropping of
3490 whitespace while wrapping.
3491
Georg Brandl92a6bae2007-03-13 17:43:32 +00003492- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003493 are set for invalid interpolation sequences that would lead to
3494 errors on reading back those values.

3534 Python would crash instead of raising an error.
3535

3537 returned string up to the first NUL character.
3538

3548
Georg Brandl3ee81df2008-05-17 18:14:43 +00003549- unittest now verifies more of its assumptions. In particular,
3550 TestCase and TestSuite subclasses (not instances) are no longer
3551 accepted in TestSuite.addTest(). This should cause no
3552 incompatibility since it never made sense with ordinary subclasses
3553 -- the failure just occurred later, with a more cumbersome
3554 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003555

3563 given a unicode argument and os.listdir() returns unicode filenames.
3564
Georg Brandl3ee81df2008-05-17 18:14:43 +00003565- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003943 time so that opening a database previously created with the DB_DUP
3944 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3945 opens. Specifically: dictionary assignment to a DB object will
3946 replace all values for a given key when the database allows
3947 duplicate values. DB users should use DB.put(k, v) when they want
3948 to store duplicates; not DB[k] = v.

3955 characters with ASCII value less than 32. Also, it correctly quotes
3956 dots only if they occur on a single line, as opposed to the previous
3957 behavior of quoting dots if they are the second character of any
3958 line.
