86
Tarek Ziadé06426fc2010-01-11 22:54:57 +000087- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

99 renaming of `cPickle` to `pickle`. The warning was annoying since there's
100 no alternative to cPickle if you care about performance. Patch by Florent
101 Xicluna.
102

Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000139- Issue #7318: multiprocessing now uses a timeout when it fails to establish

160 reading from stdin so that existing input does not confuse it and
161 lead to incorrect entry or an IOError. It also properly flushes it

175
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000176- Issue #7099: Decimal.is_normal now returns True for numbers with exponent

Vinay Sajip6badbe92009-01-20 22:49:13 +0000720- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000721 method on file objects with closefd=False. The file descriptor is still
722 kept open but the file object behaves like a closed file. The ``FileIO``
723 object also got a new readonly attribute ``closefd``.
724
Georg Brandlfa71a902008-12-05 09:08:28 +0000725- Issue #3689: The list reversed iterator now supports __length_hint__

935 302 conformant loader) will now work correctly in most cases (they
936 are still subject to the constraints that exist for all code running
937 from inside a module loaded via a PEP 302 loader and attempting to

1097==========================
1098
1099*Release date: 04-Dec-2008*
1100
1101Core and Builtins
1102-----------------
1103
1104- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1105 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1106 instead of throwing a MemoryError.
1107
1108- Issue #4367: Python would segfault during compiling when the unicodedata
1109 module couldn't be imported and \N escapes were present.
1110
1111- Issue #4348: Some bytearray methods returned that didn't cause any change to
1112 the bytearray, returned the same bytearray instead of a copy.
1113
1114- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1115
1116- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1117
1118- Issue #4048: The parser module now correctly validates relative imports.
1119
1120- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1127 __future__ import didn't work.
1128
1129- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1130 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1131 really executed because I cannot move to such directory on win2k)
1132
1133- Issue #4069: When set.remove(element) is used with a set element, the element
1134 is temporarily replaced with an equivalent frozenset. But the eventual
1135 KeyError would always report the empty frozenset([]) as the missing key. Now
1136 it correctly refers to the initial element.
1137

1139 again.

1290 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001307- Issue #3683: Fix compilation when --without-threads is given.
1308
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001309- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001310 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001311 was correctly parsed but parsing of subsequent arguments failed.
1312
Vinay Sajip35e3b032008-09-01 14:33:59 +00001313- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001314 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1315 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1316 when given a tuple of classes as second argument, were looking up
1317 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1318 type object.
1319
Neal Norwitz18aa3882008-08-24 05:04:52 +00001320- Fix crashes on memory allocation failure found with failmalloc.

1389 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1390 for catch_warnings() also led to an improvement in the raising of a
1391 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001454What's New in Python 2.6 beta 3?
1455================================
1456
Barry Warsaw07a4a382008-08-21 01:15:08 +00001457*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001458
1459Core and Builtins
1460-----------------
1461
Guido van Rossumf8402962008-08-20 15:01:50 +00001462- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1463 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1464 extensions do not automatically benefit from the class attribute
1465 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1466 to their tp_flags field if they care. This is a backwards
1467 compatibility feature; in 3.0, all types will use the cache by
1468 default.
1469
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001470- Keyword arguments can now follow starred arguments. (``f(a, *args,
1471 keyword=23)`` is now valid syntax.)
1472
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001473- ctypes function pointers that are COM methods have a boolean True
1474 value again.
1475
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001476- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1477 by denying s# to parse objects that have a releasebuffer procedure,
1478 and introducing s*.
1479
Georg Brandl1e13ea92008-08-11 09:07:59 +00001480- Issue #3537: Fix an assertion failure when an empty but presized dict
1481 object was stored in the freelist.
1482
Mark Dickinsonb6467572008-08-04 21:30:09 +00001483- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1484 ValueError consistently across platforms.
1485
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001486- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1487 (64bit Unix, for example), unichr() would truncate its argument and return
1488 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1489
Neal Norwitze7d8be82008-07-31 17:17:14 +00001490- Apply security patches from Apple.
1491
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001492- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1493 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1494
Antoine Pitrou92f82162008-07-25 22:22:08 +00001495- Issue #1819: function calls with several named parameters are now on
1496 average 35% faster (as measured by pybench).
1497
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001498- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1499 the python debugger steps into a class statement: the free variables (local
1500 variables defined in an outer scope) would be deleted from the outer scope.
1501
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001502- Issue #2620: Overflow checking when allocating or reallocating memory
1503 was not always being done properly in some python types and extension
1504 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1505 all been updated to perform better checks and places in the code that
1506 would previously leak memory on the error path when such an allocation
1507 failed have been fixed.

1511
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001512- Issue #3612: Added some missing basic types in ctypes.wintypes.
1513
Benjamin Petersone977ad42008-08-20 01:42:01 +00001514- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1515 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1516
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001517- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1518 version reported by these tools does not necessarily follow the python
1519 version numbering scheme, so the module is less strict when parsing it.
1520
Nick Coghlanf70385a2008-08-18 12:42:46 +00001521- Issue #2235: Added Py3k warnings for types which will become unhashable
1522 under the stricter __hash__ inheritance rules in 3.0. Several types
1523 which did not meet the rules for hash invariants and were already
1524 unhashable in 3.0 have now been explicitly flagged as unhashable in
1525 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1526 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1527
Brett Cannon88f801d2008-08-18 00:46:22 +00001528- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1529 imported into the module but exposed as part of the module's API.
1530
Brett Cannon7b96f072008-08-18 00:41:11 +00001531- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1532
Brett Cannon46225e72008-08-18 00:36:52 +00001533- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001535- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1536
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001537- Issue #3575: Incremental decoder's decode function now takes bytearray
1538 by using 's*' instead of 't#'.
1539
Jesus Cea585ad8a2009-07-02 15:37:21 +00001540- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001541 fails unicode conversion on 2nd parameter. (windows only)
1542
Facundo Batista94f243a2008-08-17 03:38:39 +00001543- Issue 2464. urllib2 now supports a malformation in the URL received
1544 in a redirect.
1545
Brett Cannonabe423e2008-08-16 21:47:07 +00001546- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001547 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001548
Facundo Batistaeb90b782008-08-16 14:44:07 +00001549- Issue #2776: fixed small issue when handling an URL with double slash
1550 after a 302 response in the case of not going through a proxy.
1551
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001552- Issue #2676: in the email package, content-type parsing was hanging on
1553 pathological input because of quadratic or exponential behaviour of a
1554 regular expression.
1555
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001556- Issue #3476: binary buffered reading through the new "io" library is now
1557 thread-safe.
1558
Brett Cannonbf3157b2008-08-14 05:00:03 +00001559- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1560 since mimetools itself is deprecated. Because modules are cached, all
1561 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1562
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001563- Issue #3134: shutil referenced undefined WindowsError symbol.
1564
Robert Schuppenies14646332008-08-10 11:01:53 +00001565- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1566 menu entries were not deleted.
1567
Brett Cannon83e81842008-08-09 23:30:55 +00001568- Copied the implementation of reduce() to _functools.reduce() to have a
1569 version that did not raise a DeprecationWarning under -3.
1570
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001571- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1572 a MemoryError rather than silently stop the iteration.
1573
Guido van Rossum59ce9012008-08-09 14:55:34 +00001574- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1575 to _sre.compile() will now be rejected. This should not affect anybody
1576 since the re.compile() function never generates invalid re-bytecode.
1577
Skip Montanaroa032bf42008-08-08 22:52:51 +00001578- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1579 upon first access it can be automatically initialized from the csv file if
1580 it wasn't initialized during instantiation.
1581
Brett Cannon3aa2a492008-08-06 22:28:09 +00001582- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1583 the reload() built-in has been removed.
1584
Brett Cannon7e30b672008-08-04 21:52:25 +00001585- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001586 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001597 asking for a specific length. This problem only affected files opened

1650
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001651*Release date: 17-Jul-2008*

1654-----------------
1655
Georg Brandl3e483f62008-07-16 22:57:41 +00001656- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1657 its methods now allow for items objects that can be converted to
1658 an integer using operator.index().
1659
Mark Dickinson64b7e502008-07-16 09:40:03 +00001660- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1661 produced a ValueError instead of giving the correct float.
1662
Eric Smitha5fa5a22008-07-16 00:11:49 +00001663- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1664 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1665
Mark Dickinson7103aa42008-07-15 19:08:33 +00001666- Issue #3008: the float type has a new instance method 'float.hex'
1667 and a new class method 'float.fromhex' to convert floating-point
1668 numbers to and from hexadecimal strings, respectively.
1669
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001670- Issue #2235: __hash__ is once again inherited by default. To allow
1671 collections.Hashable to remain meaningful in the presence of the
1672 default hash implementation (object.__hash__), it is now possible
1673 to explicit block inheritance of hash by setting __hash__=None at
1674 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1675 level.
1676
Nick Coghlanb028f502008-07-13 14:52:36 +00001677- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1678 the parent module cannot be found while performing an absolute import.
1679 This means that an incorrectly defined __package__ attribute will
1680 now only prevent relative imports in that module rather than causing
1681 all imports from that module to fail.
1682
Nick Coghlan14ff9942008-07-08 14:21:42 +00001683- Issue #2517: Allow unicode messages in Exceptions again by correctly

1693 another thread's dictionary.
1694
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001695- Issue #3004: Minor change to slice.indices(): the start and stop
1696 arguments are now treated identically, making the behaviour easier
1697 to describe and understand. For example, slice(None, -10,
1698 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1699 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1700 10, -1).
1701
Georg Brandl278fc502008-07-19 12:46:12 +00001702- Issue #3219: Calling a function with repeated keyword arguments,
1703 f(a=2, a=23), would not cause a syntax error. This was a regression
1704 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00001706- Issue #2862: Make int and float freelist management consistent with
1707 other freelists. Changes their CompactFreeList apis into

1714 api functions without holding the GIL, which could lead to a fatal
1715 error when they failed.
1716
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001717- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001742- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1743 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001744 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001745 content-length. The problem had been corrected in the 2.4 branch, but never
1746 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001761- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1762 handling is now the same as that of other special attributes like __name__).
1763
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001764- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

2171
Georg Brandl74a1dea2008-05-28 11:21:39 +00002172- Add ``PyType_Modified()`` as a public API to clear the type cache.
2173
2174- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002175
2176- The PyString functions have been renamed to PyBytes. A batch of
2177 defines were added so that the linker still sees the original
2178 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002216- Issue #1631171: Re-implement the 'warnings' module in C (the
2217 original Python code has been kept as backup). This will allow for
2218 using the 'warning's machinery in such places as the parser where
2219 use of pure Python code is not possible. Both the ``showarning()``
2220 and ``formatwarning()`` gain an optional 'line' argument which is
2221 not called by default for backwards-compatibility reasons. Setting
2222 ``warnings.showwarning()`` to an implementation that lacks support
2223 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002248- The getpass module has been improved on Unix. It now uses /dev/tty
2249 by default and uses stderr instead of stdout. A GetPassWarning is
2250 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002265- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002266 extension modules between 32 and 64 bit platforms. See the distutls

2279 so the controlled environment will more closely mirror the typical
2280 script environment. This supports setup.py scripts that refer to
2281 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002286- Issue #2550: The approach used by client/server code for obtaining
2287 ports to listen on in network-oriented tests has been refined in an
2288 effort to facilitate running multiple instances of the entire
2289 regression test suite in parallel without issue.
2290 test_support.bind_port() has been fixed such that it will always
2291 return a unique port -- which wasn't always the case with the
2292 previous implementation, especially if socket options had been set
2293 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2294 new implementation of bind_port() will actually raise an exception
2295 if it is passed an AF_INET/SOCK_STREAM socket with either the
2296 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2297 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2298 the socket it's been passed. This currently only applies to
2299 Windows. This option prevents any other sockets from binding to the
2300 host/port we've bound to, thus removing the possibility of the
2301 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2302 when a second SOCK_STREAM socket binds and accepts to a host/port
2303 that's already been bound by another socket. The optional preferred
2304 port parameter to bind_port() has been removed. Under no
2305 circumstances should tests be hard coding ports!
2306
2307 test_support.find_unused_port() has also been introduced, which will
2308 pass a temporary socket object to bind_port() in order to obtain an
2309 unused port. The temporary socket object is then closed and
2310 deleted, and the port is returned. This method should only be used
2311 for obtaining an unused port in order to pass to an external program
2312 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2313 a parameter to a server-oriented class that doesn't give you direct
2314 access to the underlying socket used.
2315
2316 Finally, test_support.HOST has been introduced, which should be used
2317 for the host argument of any relevant socket calls (i.e. bind and
2318 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002319
2320 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002321 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002322 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2323 test_asynchat and test_socket_ssl.
2324
Georg Brandl3ee81df2008-05-17 18:14:43 +00002325 It is now possible for multiple instances of the regression test
2326 suite to run in parallel without issue.

2593-----------------
2594
Fred Drakea8ee94b2008-03-01 02:45:07 +00002595- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002596 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002598- Issue #2067: file.__exit__() now calls subclasses' close() method.
2599
2600- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002601
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002602- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002603 issue 215555 for a discussion.
2604
Eric Smitha73fbe72008-02-23 03:09:44 +00002605- Added the future_builtins module, which contains hex() and oct().
2606 These are the PEP 3127 version of these functions, designed to be
2607 compatible with the hex() and oct() builtins from Python 3.0. They
2608 differ slightly in their output formats from the existing, unchanged
2609 Python 2.6 builtins. The expected usage of the future_builtins
2610 module is:
2611 from future_builtins import hex, oct
2612
Eric Smith7ef40bf2008-02-20 23:34:22 +00002613- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2614 exponents for exponents with absolute value < 100. Follows C99
2615 standard. This is a change on Windows, which would use 3 digits.
2616 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2617 so that any alterations it does to the resulting string will be
2618 available in stringlib/formatter.h (for float.__format__).
2619
Eric Smith5a3c1352008-02-19 13:21:56 +00002620- Implemented PEP 3101, Advanced String Formatting. This adds a new
2621 builtin format(); a format() method for str and unicode; a
2622 __format__() method to object, str, unicode, int, long, float, and
2623 datetime; the class string.Formatter; and the C API
2624 PyObject_Format().
2625
Georg Brandl3ee81df2008-05-17 18:14:43 +00002626- Fixed several potential crashes, all caused by specially crafted
2627 __del__ methods exploiting objects in temporarily inconsistent
2628 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002629
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002630- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002631 prevent a possible crash: an Abstract Base Class would try to access
2632 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002633

Georg Brandl3ee81df2008-05-17 18:14:43 +00002637- Clear all free lists during a gc.collect() of the highest generation
2638 in order to allow pymalloc to free more arenas. Python may give back
2639 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002640
Georg Brandl3ee81df2008-05-17 18:14:43 +00002641- Issue #2045: Fix an infinite recursion triggered when printing a
2642 subclass of collections.defaultdict, if its default_factory is set
2643 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002644
Christian Heimesf75dbef2008-02-08 00:11:31 +00002645- Fixed a minor memory leak in dictobject.c. The content of the free
2646 list was not freed on interpreter shutdown.
2647
Georg Brandl3ee81df2008-05-17 18:14:43 +00002648- Limit free list of method and builtin function objects to 256
2649 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002650
Georg Brandl3ee81df2008-05-17 18:14:43 +00002651- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2652 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002653 to compact the internal free lists of pre-allocted ints and floats.
2654
Georg Brandl3ee81df2008-05-17 18:14:43 +00002655- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2656 calls. Python expected the return type int but the fork familie
2657 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002658
Georg Brandl3ee81df2008-05-17 18:14:43 +00002659- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002671- Patch #1473257: generator objects gain a gi_code attribute. This is
2672 the same object as the func_code attribute of the function that
2673 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002674
Georg Brandl3ee81df2008-05-17 18:14:43 +00002675- Issue #1920: "while 0" statements were completely removed by the
2676 compiler, even in the presence of an "else" clause, which is
2677 supposed to be run when the condition is false. Now the compiler

Guido van Rossumeead05f2008-01-24 18:21:02 +00002680- A few crashers fixed: weakref_in_del.py (issue #1377858);
2681 loosing_dict_ref.py (issue #1303614, test67.py);
2682 borrowed_ref_[34].py (not in tracker).
2683
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002684- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002685 suppressed while an extension is loaded by calling SetErrorMode in
2686 dynload_win.c. The error is still reported properly.
2687
Georg Brandl3ee81df2008-05-17 18:14:43 +00002688- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002689 several extension methods and modules do not work without unicode
2690 support.
2691
Georg Brandl26543b12008-01-21 18:36:51 +00002692- Issue #1882: when compiling code from a string, encoding cookies in the
2693 second line of code were not always recognized correctly.
2694
Georg Brandl14404b62008-01-19 19:27:05 +00002695- Issue #1679: "0x" was taken as a valid integer literal.
2696
Georg Brandl6caad7d2008-01-26 14:19:22 +00002697- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002698 added.
2699
Christian Heimesc94e2b52008-01-14 04:13:37 +00002700- sys.float_info / PyFloat_GetInfo: The floating point information
2701 object was converted from a dict to a specialized structseq object.
2702
Georg Brandl3ee81df2008-05-17 18:14:43 +00002703- Patch #1816: Added sys.flags structseq. It exposes the status of
2704 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002705
Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Objects/structseq.c: Implemented new structseq representation. The
2707 patch makes structseqs (e.g. the return value of os.stat) more
2708 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002709
Georg Brandl3ee81df2008-05-17 18:14:43 +00002710- Patch #1700288: added a type attribute cache that caches method
2711 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002712
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002713- Bug #1776: __import__() no longer accepts filenames on any platform.
2714 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002715
Georg Brandlaed6c662008-01-07 17:25:53 +00002716- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2717
Georg Brandl3ee81df2008-05-17 18:14:43 +00002718- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2719 envvar and sys.dont_write_bytecode attribute. All these can be set
2720 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002721
Georg Brandl3ee81df2008-05-17 18:14:43 +00002722- Improve some exception messages when Windows fails to load an
2723 extension module. Now we get for example '%1 is not a valid Win32
2724 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002725
Georg Brandl3ee81df2008-05-17 18:14:43 +00002726- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002728- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2729 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002730
Christian Heimes0a8143f2007-12-18 23:22:54 +00002731- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002732 and INF. float("nan"), float("inf") and float("-inf") now work on
2733 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002734
Georg Brandl3ee81df2008-05-17 18:14:43 +00002735- Compiler now generates simpler and faster code for dictionary
2736 literals. The oparg for BUILD_MAP now indicates an estimated
2737 dictionary size. There is a new opcode, STORE_MAP, for adding
2738 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002739
Georg Brandl3ee81df2008-05-17 18:14:43 +00002740- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002748- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002749 SystemError.
2750
Nick Coghlanef01d822007-12-03 12:55:17 +00002751- PEP 366: Allow explicit relative imports when executing modules

2756 running, and if the deallocation of its frames somehow calls the
2757 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002758

2763
Georg Brandl3ee81df2008-05-17 18:14:43 +00002764- Issue #1460: The utf-7 incremental decoder did not accept truncated
2765 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002766
Georg Brandl3ee81df2008-05-17 18:14:43 +00002767- Patch #1739468: Directories and zipfiles containing a __main__.py
2768 file can now be directly executed by passing their name to the
2769 interpreter. The directory/zipfile is automatically inserted as the
2770 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002771
Georg Brandl3ee81df2008-05-17 18:14:43 +00002772- Issue #1265: Fix a problem with sys.settrace, if the tracing
2773 function uses a generator expression when at the same time the
2774 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002775
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002776- sets and frozensets now have an isdisjoint() method.
2777
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002778- optimize the performance of builtin.sum().
2779
Neal Norwitz44f326e2007-10-05 05:29:17 +00002780- Fix warnings found by the new version of the Coverity checker.
2781
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782- The enumerate() builtin function is no longer bounded to sequences
2783 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2784 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002785
Georg Brandl3ee81df2008-05-17 18:14:43 +00002786- Issue #1686386: Tuple's tp_repr did not take into account the
2787 possibility of having a self-referential tuple, which is possible
2788 from C code. Nor did object's tp_str consider that a type's tp_str
2789 could do something that could lead to an inifinite recursion.
2790 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2791 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002792
Georg Brandl3ee81df2008-05-17 18:14:43 +00002793- Issue #1164: It was possible to trigger deadlock when using the
2794 'print' statement to write to a file since the GIL was not released
2795 as needed. Now PyObject_Print() does the right thing along with
2796 various tp_print implementations of the built-in types and those in
2797 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002798
Georg Brandl3ee81df2008-05-17 18:14:43 +00002799- Issue #1147: Exceptions were directly allowing string exceptions in
2800 their throw() method even though string exceptions no longer
2801 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002802
Georg Brandl3ee81df2008-05-17 18:14:43 +00002803- Issue #1096: Prevent a segfault from getting the repr of a very
2804 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002805
Brett Cannon1e534b52007-09-07 04:18:30 +00002806- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002807 PyObject_Call() never calling back out to Python code to trigger
2808 recursion depth updates/checks. Required the creation of a static
2809 RuntimeError instance in case normalizing an exception put the
2810 recursion check value past its limit. Fixes crashers
2811 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002812
Georg Brandl3ee81df2008-05-17 18:14:43 +00002813- Patch #1031213: Decode source line in SyntaxErrors back to its

2817 with %G.
2818
Georg Brandl3ee81df2008-05-17 18:14:43 +00002819- Prevent expandtabs() on string and unicode objects from causing a
2820 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002826- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002827 __*__ attributes. (Some already existed, e.g., __doc__ and
2828 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002829
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002830- Add -3 option to the interpreter to warn about features that are
2831 deprecated and will be changed/removed in Python 3.0.
2832
Georg Brandl2134e752007-05-21 20:34:16 +00002833- Patch #1686487: you can now pass any mapping after '**' in function
2834 calls.
2835
Collin Winter62903052007-05-18 23:11:24 +00002836- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837 "except E as target:". This is to provide forwards compatibility
2838 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002839
Brett Cannon229cee22007-05-05 01:34:02 +00002840- Deprecate BaseException.message as per PEP 352.
2841
Georg Brandl3ee81df2008-05-17 18:14:43 +00002842- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002843 inherited from a builtin base.
2844
Vinay Sajip8549ce32007-05-06 17:53:37 +00002845- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002846 setting a plain string, ie don't expand to single letter identifiers.
2847
Raymond Hettinger13936692007-04-11 18:40:58 +00002848- Request #1191699: Slices can now be pickled.
2849
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002850- Request #1193128: str.translate() now allows a None argument for
2851 translations that only remove characters without re-mapping the
2852 remaining characters.
2853
Georg Brandl5cb76c12007-03-21 09:00:39 +00002854- Patch #1682205: a TypeError while unpacking an iterable is no longer
2855 masked by a generic one with the message "unpack non-sequence".
2856
Neal Norwitzaa754b72007-03-21 06:39:48 +00002857- Remove unused file Python/fmod.c.
2858
Guido van Rossum143b5642007-03-23 04:58:42 +00002859- Bug #1683368: The object.__init__() and object.__new__() methods are
2860 now stricter in rejecting excess arguments. The only time when
2861 either allows excess arguments is when it is not overridden and the
2862 other one is. For backwards compatibility, when both are
2863 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002864 warning later). Also, type.__init__() insists on the same signature
2865 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002866
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2868 object to complex using its __complex__() method before falling back
2869 to the __float__() method. Therefore, the functions in the cmath
2870 module now can operate on objects that define a __complex__()
2871 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002872
Georg Brandl3ee81df2008-05-17 18:14:43 +00002873- Patch #1623563: allow __class__ assignment for classes with
2874 __slots__. The old and the new class are still required to have the
2875 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002876
Georg Brandl3ee81df2008-05-17 18:14:43 +00002877- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Patch #1462488: Python no longer segfaults when
2881 ``object.__reduce_ex__()`` is called with an object that is faking
2882 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002883
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002887- Patch #1444529: the builtin compile() now accepts keyword arguments.
2888
Georg Brandl7b9c5552007-03-12 14:30:05 +00002889- Bug #1678647: write a newline after printing an exception in any
2890 case, even when converting the value to a string failed.
2891
Georg Brandl871f1bc2007-03-12 13:17:36 +00002892- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002893 its argument, if it exists. If not, it will work like before. This
2894 allows customizing the output of dir() in the presence of a
2895 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002896
Collin Winter276887b2007-03-12 16:11:39 +00002897- Patch #922167: Python no longer segfaults when faced with infinitely
2898 self-recursive reload() calls (as reported by bug #742342).
2899
Georg Brandl3ee81df2008-05-17 18:14:43 +00002900- Patch #1675981: remove unreachable code from ``type.__new__()``
2901 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002903- Patch #1491866: change the complex() constructor to allow
2904 parthensized forms. This means complex(repr(x)) now works instead of
2905 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002906
Georg Brandlaa2321b2007-03-07 00:40:28 +00002907- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002908 makes the filenames the warning module prints much more sensible
2909 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002910
Georg Brandl49aafc92007-03-07 00:34:46 +00002911- Variant of patch #697613: don't exit the interpreter on a SystemExit
2912 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002913 variable is given, but break into the interactive interpreter just
2914 like on other exceptions or normal program exit.

3412 only useful in Unix/Linux environments.
3413
Georg Brandlfb4b3b72007-04-24 15:27:13 +00003414- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
3415 (as opposed to the command line) will now write file names ending in
3416 ".cpp" too.
3417
Facundo Batistad918a652007-04-24 13:54:38 +00003418- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003419 the client's request was successfully received, understood, and
3420 accepted. Now in these cases no error is raised in urllib (issue
3421 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003422
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423- Bug #1290505: time.strptime's internal cache of locale information

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003429- Added a timeout parameter to the constructor of other protocols
3430 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3431 work started with create_connection() and timeout in httplib, and
3432 closes patch #723312.
3433
Vinay Sajip8549ce32007-05-06 17:53:37 +00003434- Patch #1676823: Added create_connection() to socket.py, which may be
3435 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003436 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003437
Martin v. Löwis0af33882007-03-23 13:27:15 +00003438- Bug #978833: Revert r50844, as it broke _socketobject.dup.
3439

Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3446 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003447 directories.
3448

3458
Georg Brandlf66b6032007-03-14 08:27:52 +00003459- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003460 AttributeError instead of an IOError when the server's response
3461 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003462
Georg Brandl3ee81df2008-05-17 18:14:43 +00003463- Patch #957650: "%var%" environment variable references are now
3464 properly expanded in ntpath.expandvars(), also "~user" home
3465 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003466
Georg Brandl3ee81df2008-05-17 18:14:43 +00003467- Patch #1429539: pdb now correctly initializes the __main__ module
3468 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003469 correctly now.
3470
Georg Brandlbad6f192007-03-13 21:32:56 +00003471- The nonobvious commands.getstatus() function is now deprecated.

3477
Georg Brandl3ee81df2008-05-17 18:14:43 +00003478- Patch #1530482: add pydoc.render_doc() which returns the
3479 documentation for a thing instead of paging it to stdout, which
3480 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003481
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Patch #1533909: the timeit module now accepts callables in addition

3488 parameter which can be set to False to prevent the default
3489 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003490
Georg Brandl9e6b4702007-03-13 18:15:41 +00003491- Patch #1581073: add a flag to textwrap that prevents the dropping of
3492 whitespace while wrapping.
3493
Georg Brandl92a6bae2007-03-13 17:43:32 +00003494- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003495 are set for invalid interpolation sequences that would lead to
3496 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003497

3510
Georg Brandl94fe3f52007-03-13 09:32:11 +00003511- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003512 field names in its exception message if you try to write a record
3513 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003531

3539 returned string up to the first NUL character.

3550
Georg Brandl3ee81df2008-05-17 18:14:43 +00003551- unittest now verifies more of its assumptions. In particular,
3552 TestCase and TestSuite subclasses (not instances) are no longer
3553 accepted in TestSuite.addTest(). This should cause no
3554 incompatibility since it never made sense with ordinary subclasses
3555 -- the failure just occurred later, with a more cumbersome
3556 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003557

3565 given a unicode argument and os.listdir() returns unicode filenames.
3566
Georg Brandl3ee81df2008-05-17 18:14:43 +00003567- Patch #1673619: setup.py identifies extension modules it doesn't
3568 know how to build and those it knows how to build but that fail to
3569 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003944- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003945 time so that opening a database previously created with the DB_DUP
3946 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3947 opens. Specifically: dictionary assignment to a DB object will
3948 replace all values for a given key when the database allows
3949 duplicate values. DB users should use DB.put(k, v) when they want
3950 to store duplicates; not DB[k] = v.

3957 characters with ASCII value less than 32. Also, it correctly quotes
3958 dots only if they occur on a single line, as opposed to the previous
3959 behavior of quoting dots if they are the second character of any
3960 line.
