12Core and Builtins
13-----------------
14
Victor Stinner082a65a2010-07-28 01:55:43 +000015- Issue #6213: Implement getstate() and setstate() methods of utf-8-sig and
16 utf-16 incremental encoders.
17
Ezio Melotti86e5e172010-07-03 05:34:39 +000018- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
19 start byte and the continuation byte(s) are now considered invalid, instead
20 of the number of bytes specified by the start byte.
21 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
22 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
23 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
24 Previous versions returned a single u'\ufffd'.
25
Benjamin Peterson8d649632010-06-22 19:21:33 +000026- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
27
Antoine Pitrou4595e512010-06-11 21:48:02 +000028- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
29 the interpreter with characters outside the Basic Multilingual Plane
30 (higher than 0x10000).
31
Mark Dickinson80068da2010-06-05 11:59:41 +000032- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsonb671c292010-06-05 12:15:35 +000033 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
34 arises from the "Overriding __eq__ blocks inheritance ..." warning
35 when turned into an exception: in this case the exception simply
36 gets ignored.
Mark Dickinson80068da2010-06-05 11:59:41 +000037
Georg Brandl0ba1f012010-08-01 22:00:39 +000038- Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *'
39 entries, consider the first one.
40
Georg Brandl86edb142010-08-01 21:58:18 +000041- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.
42
Benjamin Peterson85633362010-06-08 14:58:25 +000043- In the unicode/str.format(), raise a ValueError when indexes to arguments are
44 too large.
Benjamin Petersonc9719132010-06-07 22:27:32 +000045
Victor Stinnerc3e40e02010-05-25 22:40:38 +000046- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
47 and error handler, instead of writing to the C stderr file in utf-8
48
Brett Cannon7d006262010-05-20 18:41:08 +000049- Issue #7902: When using explicit relative import syntax, don't try
50 implicit relative import semantics.
51
Antoine Pitrou5de15942010-05-17 20:00:52 +000052- Issue #7079: Fix a possible crash when closing a file object while using
53 it from another thread. Patch by Daniel Stutzbach.
54
Mark Dickinsone02c9d22010-05-07 13:23:18 +000055- Issue #1533: fix inconsistency in range function argument
56 processing: any non-float non-integer argument is now converted to
57 an integer (if possible) using its __int__ method. Previously, only
58 small arguments were treated this way; larger arguments (those whose
59 __int__ was outside the range of a C long) would produce a TypeError.
60
Benjamin Petersonc218ce82010-04-16 22:43:53 +000061- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

68
Georg Brandleb412142010-05-18 23:19:34 +000069- Issue #1583863: An unicode subclass can now override the __unicode__ method.
70
71- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
Victor Stinner4fd2ff92010-03-22 12:56:39 +000072
Victor Stinnerd156fa32010-03-21 13:32:31 +000073- Issue #7544: Preallocate thread memory before creating the thread to avoid
74 a fatal error in low memory condition.
75
Victor Stinner0217c952010-03-21 13:09:24 +000076- Issue #7820: The parser tokenizer restores all bytes in the right if
77 the BOM check fails.

83
84- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
85 embedders of the interpreter to set sys.argv without also modifying
86 sys.path. This helps fix `CVE-2008-5983
87 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

Gregory P. Smith034ec782010-07-25 20:00:02 +0000145- Issue #3704: cookielib was not properly handling URLs with a / in the

1481 zipimport (or any other conformant PEP 302 loader). Original patch by

1483
1484- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1485 302 conformant loader) will now work correctly in most cases (they
1486 are still subject to the constraints that exist for all code running
1487 from inside a module loaded via a PEP 302 loader and attempting to

1646What's New in Python 2.6.1
1647==========================
1648
1649*Release date: 04-Dec-2008*
1650
1651Core and Builtins
1652-----------------
1653
1654- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1655 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1656 instead of throwing a MemoryError.
1657
1658- Issue #4367: Python would segfault during compiling when the unicodedata
1659 module couldn't be imported and \N escapes were present.
1660
1661- Issue #4348: Some bytearray methods returned that didn't cause any change to
1662 the bytearray, returned the same bytearray instead of a copy.
1663
1664- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1665
1666- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1667
1668- Issue #4048: The parser module now correctly validates relative imports.
1669
1670- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1676- Issue #4209: Enabling unicode_literals and the print_function in the same
1677 __future__ import didn't work.
1678
1679- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1680 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1681 really executed because I cannot move to such directory on win2k)
1682
1683- Issue #4069: When set.remove(element) is used with a set element, the element
1684 is temporarily replaced with an equivalent frozenset. But the eventual
1685 KeyError would always report the empty frozenset([]) as the missing key. Now
1686 it correctly refers to the initial element.
1687
1688- Fixed C99 style comments in several files. Python is now C89 compatible
1689 again.

1837
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001838- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1839 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1840 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1841 ``printf`` function, whereas PyString_FromFormat has an independent
1842 implementation and uses "%zd" on all platforms for size_t values.
1843 This makes a difference on win64, where ``printf`` needs "%Id" to display

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001963- Issue #2975: When compiling several extension modules with Visual Studio 2008
1964 from the same python interpreter, some environment variables would grow
1965 without limit.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002004What's New in Python 2.6 beta 3?
2005================================
2006
Barry Warsaw07a4a382008-08-21 01:15:08 +00002007*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002008
2009Core and Builtins
2010-----------------
2011
Guido van Rossumf8402962008-08-20 15:01:50 +00002012- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2013 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2014 extensions do not automatically benefit from the class attribute
2015 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2016 to their tp_flags field if they care. This is a backwards
2017 compatibility feature; in 3.0, all types will use the cache by
2018 default.
2019
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002020- Keyword arguments can now follow starred arguments. (``f(a, *args,
2021 keyword=23)`` is now valid syntax.)
2022
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002023- ctypes function pointers that are COM methods have a boolean True
2024 value again.
2025
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002026- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2027 by denying s# to parse objects that have a releasebuffer procedure,
2028 and introducing s*.
2029
Georg Brandl1e13ea92008-08-11 09:07:59 +00002030- Issue #3537: Fix an assertion failure when an empty but presized dict
2031 object was stored in the freelist.
2032
Mark Dickinsonb6467572008-08-04 21:30:09 +00002033- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2034 ValueError consistently across platforms.
2035
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002036- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2037 (64bit Unix, for example), unichr() would truncate its argument and return
2038 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2039
Neal Norwitze7d8be82008-07-31 17:17:14 +00002040- Apply security patches from Apple.
2041
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002042- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2043 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2044
Antoine Pitrou92f82162008-07-25 22:22:08 +00002045- Issue #1819: function calls with several named parameters are now on
2046 average 35% faster (as measured by pybench).
2047
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002048- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2049 the python debugger steps into a class statement: the free variables (local
2050 variables defined in an outer scope) would be deleted from the outer scope.
2051
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002052- Issue #2620: Overflow checking when allocating or reallocating memory
2053 was not always being done properly in some python types and extension
2054 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2055 all been updated to perform better checks and places in the code that
2056 would previously leak memory on the error path when such an allocation
2057 failed have been fixed.

2063
Benjamin Petersone977ad42008-08-20 01:42:01 +00002064- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2065 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2066
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002067- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2068 version reported by these tools does not necessarily follow the python
2069 version numbering scheme, so the module is less strict when parsing it.
2070
Nick Coghlanf70385a2008-08-18 12:42:46 +00002071- Issue #2235: Added Py3k warnings for types which will become unhashable
2072 under the stricter __hash__ inheritance rules in 3.0. Several types
2073 which did not meet the rules for hash invariants and were already
2074 unhashable in 3.0 have now been explicitly flagged as unhashable in
2075 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2076 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2077
Brett Cannon88f801d2008-08-18 00:46:22 +00002078- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2082
Brett Cannon46225e72008-08-18 00:36:52 +00002083- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002085- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2086
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002087- Issue #3575: Incremental decoder's decode function now takes bytearray
2088 by using 's*' instead of 't#'.
2089
Jesus Cea585ad8a2009-07-02 15:37:21 +00002090- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002091 fails unicode conversion on 2nd parameter. (windows only)
2092
Facundo Batista94f243a2008-08-17 03:38:39 +00002093- Issue 2464. urllib2 now supports a malformation in the URL received
2094 in a redirect.
2095
Brett Cannonabe423e2008-08-16 21:47:07 +00002096- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002097 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002098
Facundo Batistaeb90b782008-08-16 14:44:07 +00002099- Issue #2776: fixed small issue when handling an URL with double slash
2100 after a 302 response in the case of not going through a proxy.
2101
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002102- Issue #2676: in the email package, content-type parsing was hanging on
2103 pathological input because of quadratic or exponential behaviour of a
2104 regular expression.
2105
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002106- Issue #3476: binary buffered reading through the new "io" library is now
2107 thread-safe.
2108
Brett Cannonbf3157b2008-08-14 05:00:03 +00002109- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2110 since mimetools itself is deprecated. Because modules are cached, all
2111 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2112
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002113- Issue #3134: shutil referenced undefined WindowsError symbol.
2114
Robert Schuppenies14646332008-08-10 11:01:53 +00002115- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2116 menu entries were not deleted.
2117
Brett Cannon83e81842008-08-09 23:30:55 +00002118- Copied the implementation of reduce() to _functools.reduce() to have a
2119 version that did not raise a DeprecationWarning under -3.
2120
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002121- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2122 a MemoryError rather than silently stop the iteration.
2123
Guido van Rossum59ce9012008-08-09 14:55:34 +00002124- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2125 to _sre.compile() will now be rejected. This should not affect anybody
2126 since the re.compile() function never generates invalid re-bytecode.
2127
Skip Montanaroa032bf42008-08-08 22:52:51 +00002128- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2129 upon first access it can be automatically initialized from the csv file if
2130 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00002132- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2133 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00002147 asking for a specific length. This problem only affected files opened
2148 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002149

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002173- Issue #3394: zipfile.writestr sets external attributes when passed a
2174 file name rather than a ZipInfo instance, so files are extracted with
2175 mode 0600 rather than 000 under Unix.
2176
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002177- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2178 argument in python 2.5, this broke code that subclassed Popen to include its
2179 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2191
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002192- Issue #643841: The language reference now provides more detailed
2193 coverage of the lookup process for special methods. The disclaimers
2194 regarding lack of coverage of new-style classes have also been

2199================================
2200
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002201*Release date: 17-Jul-2008*
2202
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002203Core and Builtins
2204-----------------
2205
Georg Brandl3e483f62008-07-16 22:57:41 +00002206- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2207 its methods now allow for items objects that can be converted to
2208 an integer using operator.index().
2209
Mark Dickinson64b7e502008-07-16 09:40:03 +00002210- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2211 produced a ValueError instead of giving the correct float.
2212
Eric Smitha5fa5a22008-07-16 00:11:49 +00002213- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2214 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2215
Mark Dickinson7103aa42008-07-15 19:08:33 +00002216- Issue #3008: the float type has a new instance method 'float.hex'
2217 and a new class method 'float.fromhex' to convert floating-point
2218 numbers to and from hexadecimal strings, respectively.
2219
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002220- Issue #2235: __hash__ is once again inherited by default. To allow
2221 collections.Hashable to remain meaningful in the presence of the
2222 default hash implementation (object.__hash__), it is now possible
2223 to explicit block inheritance of hash by setting __hash__=None at
2224 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2225 level.
2226
Nick Coghlanb028f502008-07-13 14:52:36 +00002227- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2228 the parent module cannot be found while performing an absolute import.
2229 This means that an incorrectly defined __package__ attribute will
2230 now only prevent relative imports in that module rather than causing
2231 all imports from that module to fail.
2232
Nick Coghlan14ff9942008-07-08 14:21:42 +00002233- Issue #2517: Allow unicode messages in Exceptions again by correctly
2234 bypassing the instance dictionary when looking up __unicode__ on
2235 new-style classes.
2236
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002237- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2238 set to a custom object whose write() method happens to install
2239 another file in sys.stdout.
2240
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002241- Issue #3088: Corrected a race condition in classes derived from
2242 threading.local: the first member set by a thread could be saved in
2243 another thread's dictionary.
2244
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002245- Issue #3004: Minor change to slice.indices(): the start and stop
2246 arguments are now treated identically, making the behaviour easier
2247 to describe and understand. For example, slice(None, -10,
2248 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2249 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2250 10, -1).
2251
Georg Brandl278fc502008-07-19 12:46:12 +00002252- Issue #3219: Calling a function with repeated keyword arguments,
2253 f(a=2, a=23), would not cause a syntax error. This was a regression
2254 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002255
Georg Brandl278fc502008-07-19 12:46:12 +00002256- Issue #2862: Make int and float freelist management consistent with
2257 other freelists. Changes their CompactFreeList apis into
2258 ClearFreeList apis and calls them via gc.collect().

2262
Thomas Heller57adf222008-08-14 19:10:48 +00002263- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2264 api functions without holding the GIL, which could lead to a fatal
2265 error when they failed.
2266
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002267- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2276 ForkingPickler.register() to resolve conflict with ctypes.
2277
Vinay Sajip51e65192008-07-18 09:01:10 +00002278- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002279
Thomas Heller880f5292008-07-15 19:39:38 +00002280- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2281 a valid dlerror() message.
2282
Thomas Heller2bad6572008-07-15 17:19:50 +00002283- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2284 incomplete structure was created.

2289
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002290- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002291
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002292- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2293 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002294 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002295 content-length. The problem had been corrected in the 2.4 branch, but never
2296 merged into trunk.
2297
Georg Brandle78fbcc2008-07-05 10:13:36 +00002298- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002311- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2312 handling is now the same as that of other special attributes like __name__).
2313
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002314- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

2770 and ``formatwarning()`` gain an optional 'line' argument which is
2771 not called by default for backwards-compatibility reasons. Setting
2772 ``warnings.showwarning()`` to an implementation that lacks support
2773 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002836- Issue #2550: The approach used by client/server code for obtaining
2837 ports to listen on in network-oriented tests has been refined in an
2838 effort to facilitate running multiple instances of the entire
2839 regression test suite in parallel without issue.
2840 test_support.bind_port() has been fixed such that it will always
2841 return a unique port -- which wasn't always the case with the
2842 previous implementation, especially if socket options had been set
2843 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2844 new implementation of bind_port() will actually raise an exception
2845 if it is passed an AF_INET/SOCK_STREAM socket with either the
2846 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2847 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2848 the socket it's been passed. This currently only applies to
2849 Windows. This option prevents any other sockets from binding to the
2850 host/port we've bound to, thus removing the possibility of the
2851 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2852 when a second SOCK_STREAM socket binds and accepts to a host/port
2853 that's already been bound by another socket. The optional preferred
2854 port parameter to bind_port() has been removed. Under no
2855 circumstances should tests be hard coding ports!
2856
2857 test_support.find_unused_port() has also been introduced, which will
2858 pass a temporary socket object to bind_port() in order to obtain an
2859 unused port. The temporary socket object is then closed and
2860 deleted, and the port is returned. This method should only be used
2861 for obtaining an unused port in order to pass to an external program
2862 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2863 a parameter to a server-oriented class that doesn't give you direct
2864 access to the underlying socket used.
2865
2866 Finally, test_support.HOST has been introduced, which should be used
2867 for the host argument of any relevant socket calls (i.e. bind and
2868 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002869
2870 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002872 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2873 test_asynchat and test_socket_ssl.
2874
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875 It is now possible for multiple instances of the regression test
2876 suite to run in parallel without issue.

3143-----------------
3144
Fred Drakea8ee94b2008-03-01 02:45:07 +00003145- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003146 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003151
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003152- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003153 issue 215555 for a discussion.
3154
Eric Smitha73fbe72008-02-23 03:09:44 +00003155- Added the future_builtins module, which contains hex() and oct().
3156 These are the PEP 3127 version of these functions, designed to be
3157 compatible with the hex() and oct() builtins from Python 3.0. They
3158 differ slightly in their output formats from the existing, unchanged
3159 Python 2.6 builtins. The expected usage of the future_builtins
3160 module is:
3161 from future_builtins import hex, oct
3162
Eric Smith7ef40bf2008-02-20 23:34:22 +00003163- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3164 exponents for exponents with absolute value < 100. Follows C99
3165 standard. This is a change on Windows, which would use 3 digits.
3166 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3167 so that any alterations it does to the resulting string will be
3168 available in stringlib/formatter.h (for float.__format__).
3169
Eric Smith5a3c1352008-02-19 13:21:56 +00003170- Implemented PEP 3101, Advanced String Formatting. This adds a new
3171 builtin format(); a format() method for str and unicode; a
3172 __format__() method to object, str, unicode, int, long, float, and
3173 datetime; the class string.Formatter; and the C API
3174 PyObject_Format().
3175
Georg Brandl3ee81df2008-05-17 18:14:43 +00003176- Fixed several potential crashes, all caused by specially crafted
3177 __del__ methods exploiting objects in temporarily inconsistent
3178 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003179
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003180- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181 prevent a possible crash: an Abstract Base Class would try to access
3182 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003187- Clear all free lists during a gc.collect() of the highest generation
3188 in order to allow pymalloc to free more arenas. Python may give back
3189 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- Issue #2045: Fix an infinite recursion triggered when printing a
3192 subclass of collections.defaultdict, if its default_factory is set
3193 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003194
Christian Heimesf75dbef2008-02-08 00:11:31 +00003195- Fixed a minor memory leak in dictobject.c. The content of the free
3196 list was not freed on interpreter shutdown.
3197
Georg Brandl5a7eca12010-03-21 19:29:04 +00003198- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00003200
Georg Brandl3ee81df2008-05-17 18:14:43 +00003201- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3202 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003203 to compact the internal free lists of pre-allocted ints and floats.
3204
Georg Brandl3ee81df2008-05-17 18:14:43 +00003205- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3206 calls. Python expected the return type int but the fork familie
3207 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003208

Georg Brandl3ee81df2008-05-17 18:14:43 +00003221- Patch #1473257: generator objects gain a gi_code attribute. This is
3222 the same object as the func_code attribute of the function that
3223 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003224
Georg Brandl3ee81df2008-05-17 18:14:43 +00003225- Issue #1920: "while 0" statements were completely removed by the
3226 compiler, even in the presence of an "else" clause, which is
3227 supposed to be run when the condition is false. Now the compiler
3228 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003229
Guido van Rossumeead05f2008-01-24 18:21:02 +00003230- A few crashers fixed: weakref_in_del.py (issue #1377858);

3237
Georg Brandl3ee81df2008-05-17 18:14:43 +00003238- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003239 several extension methods and modules do not work without unicode
3240 support.

Georg Brandl6caad7d2008-01-26 14:19:22 +00003247- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003248 added.
3249
Christian Heimesc94e2b52008-01-14 04:13:37 +00003250- sys.float_info / PyFloat_GetInfo: The floating point information

Christian Heimesf31b69f2008-01-14 03:42:48 +00003255
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Objects/structseq.c: Implemented new structseq representation. The
3257 patch makes structseqs (e.g. the return value of os.stat) more
3258 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003259
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260- Patch #1700288: added a type attribute cache that caches method
3261 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003262
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003263- Bug #1776: __import__() no longer accepts filenames on any platform.
3264 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003265
Georg Brandlaed6c662008-01-07 17:25:53 +00003266- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3267
Georg Brandl3ee81df2008-05-17 18:14:43 +00003268- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3269 envvar and sys.dont_write_bytecode attribute. All these can be set
3270 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003271
Georg Brandl3ee81df2008-05-17 18:14:43 +00003272- Improve some exception messages when Windows fails to load an
3273 extension module. Now we get for example '%1 is not a valid Win32
3274 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003275
Georg Brandl3ee81df2008-05-17 18:14:43 +00003276- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003278- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3279 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003280
Christian Heimes0a8143f2007-12-18 23:22:54 +00003281- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003282 and INF. float("nan"), float("inf") and float("-inf") now work on
3283 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003284
Georg Brandl3ee81df2008-05-17 18:14:43 +00003285- Compiler now generates simpler and faster code for dictionary
3286 literals. The oparg for BUILD_MAP now indicates an estimated
3287 dictionary size. There is a new opcode, STORE_MAP, for adding
3288 entries to the dictionary.

3300
Nick Coghlanef01d822007-12-03 12:55:17 +00003301- PEP 366: Allow explicit relative imports when executing modules

3306 running, and if the deallocation of its frames somehow calls the
3307 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003308

Georg Brandl3ee81df2008-05-17 18:14:43 +00003317- Patch #1739468: Directories and zipfiles containing a __main__.py
3318 file can now be directly executed by passing their name to the
3319 interpreter. The directory/zipfile is automatically inserted as the
3320 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003321
Georg Brandl3ee81df2008-05-17 18:14:43 +00003322- Issue #1265: Fix a problem with sys.settrace, if the tracing
3323 function uses a generator expression when at the same time the
3324 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003325
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003326- sets and frozensets now have an isdisjoint() method.
3327
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003328- optimize the performance of builtin.sum().
3329
Neal Norwitz44f326e2007-10-05 05:29:17 +00003330- Fix warnings found by the new version of the Coverity checker.
3331
Georg Brandl5a7eca12010-03-21 19:29:04 +00003332- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3334 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003335
Georg Brandl3ee81df2008-05-17 18:14:43 +00003336- Issue #1686386: Tuple's tp_repr did not take into account the
3337 possibility of having a self-referential tuple, which is possible
3338 from C code. Nor did object's tp_str consider that a type's tp_str
3339 could do something that could lead to an inifinite recursion.
3340 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3341 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003342
Georg Brandl3ee81df2008-05-17 18:14:43 +00003343- Issue #1164: It was possible to trigger deadlock when using the
3344 'print' statement to write to a file since the GIL was not released
3345 as needed. Now PyObject_Print() does the right thing along with
3346 various tp_print implementations of the built-in types and those in
3347 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003348
Georg Brandl3ee81df2008-05-17 18:14:43 +00003349- Issue #1147: Exceptions were directly allowing string exceptions in
3350 their throw() method even though string exceptions no longer
3351 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003352
Georg Brandl3ee81df2008-05-17 18:14:43 +00003353- Issue #1096: Prevent a segfault from getting the repr of a very
3354 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003355
Brett Cannon1e534b52007-09-07 04:18:30 +00003356- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003357 PyObject_Call() never calling back out to Python code to trigger
3358 recursion depth updates/checks. Required the creation of a static
3359 RuntimeError instance in case normalizing an exception put the
3360 recursion check value past its limit. Fixes crashers
3361 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003362
Georg Brandl3ee81df2008-05-17 18:14:43 +00003363- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003376- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003377 __*__ attributes. (Some already existed, e.g., __doc__ and
3378 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003379
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003380- Add -3 option to the interpreter to warn about features that are
3381 deprecated and will be changed/removed in Python 3.0.
3382
Georg Brandl2134e752007-05-21 20:34:16 +00003383- Patch #1686487: you can now pass any mapping after '**' in function
3384 calls.
3385
Collin Winter62903052007-05-18 23:11:24 +00003386- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387 "except E as target:". This is to provide forwards compatibility
3388 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003389
Brett Cannon229cee22007-05-05 01:34:02 +00003390- Deprecate BaseException.message as per PEP 352.
3391
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003393 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003394
Vinay Sajip8549ce32007-05-06 17:53:37 +00003395- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003396 setting a plain string, ie don't expand to single letter identifiers.
3397
Raymond Hettinger13936692007-04-11 18:40:58 +00003398- Request #1191699: Slices can now be pickled.
3399
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003400- Request #1193128: str.translate() now allows a None argument for
3401 translations that only remove characters without re-mapping the
3402 remaining characters.
3403
Georg Brandl5cb76c12007-03-21 09:00:39 +00003404- Patch #1682205: a TypeError while unpacking an iterable is no longer
3405 masked by a generic one with the message "unpack non-sequence".
3406
Neal Norwitzaa754b72007-03-21 06:39:48 +00003407- Remove unused file Python/fmod.c.
3408
Guido van Rossum143b5642007-03-23 04:58:42 +00003409- Bug #1683368: The object.__init__() and object.__new__() methods are
3410 now stricter in rejecting excess arguments. The only time when
3411 either allows excess arguments is when it is not overridden and the
3412 other one is. For backwards compatibility, when both are
3413 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003414 warning later). Also, type.__init__() insists on the same signature
3415 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003416
Georg Brandl3ee81df2008-05-17 18:14:43 +00003417- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3418 object to complex using its __complex__() method before falling back
3419 to the __float__() method. Therefore, the functions in the cmath
3420 module now can operate on objects that define a __complex__()
3421 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003422
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423- Patch #1623563: allow __class__ assignment for classes with
3424 __slots__. The old and the new class are still required to have the
3425 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003426
Georg Brandl3ee81df2008-05-17 18:14:43 +00003427- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003430- Patch #1462488: Python no longer segfaults when
3431 ``object.__reduce_ex__()`` is called with an object that is faking
3432 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003433
Georg Brandl3ee81df2008-05-17 18:14:43 +00003434- Patch #1680015: Don't modify __slots__ tuple if it contains an

3438
Georg Brandl7b9c5552007-03-12 14:30:05 +00003439- Bug #1678647: write a newline after printing an exception in any
3440 case, even when converting the value to a string failed.
3441
Georg Brandl871f1bc2007-03-12 13:17:36 +00003442- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443 its argument, if it exists. If not, it will work like before. This
3444 allows customizing the output of dir() in the presence of a
3445 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003446
Collin Winter276887b2007-03-12 16:11:39 +00003447- Patch #922167: Python no longer segfaults when faced with infinitely
3448 self-recursive reload() calls (as reported by bug #742342).
3449
Georg Brandl3ee81df2008-05-17 18:14:43 +00003450- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003453- Patch #1491866: change the complex() constructor to allow
3454 parthensized forms. This means complex(repr(x)) now works instead of
3455 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003456
Georg Brandlaa2321b2007-03-07 00:40:28 +00003457- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458 makes the filenames the warning module prints much more sensible
3459 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003460
Georg Brandl49aafc92007-03-07 00:34:46 +00003461- Variant of patch #697613: don't exit the interpreter on a SystemExit
3462 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003463 variable is given, but break into the interactive interpreter just
3464 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00003471
Georg Brandl0fca97a2007-03-05 22:28:08 +00003472- Patch #1674228: when assigning a slice (old-style), check for the
3473 sq_ass_slice instead of the sq_slice slot.
3474
Georg Brandl3ee81df2008-05-17 18:14:43 +00003475- When printing an unraisable error, don't print exceptions. before
3476 the name. This duplicates the behavior whening normally printing
3477 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003478

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003979- Added a timeout parameter to the constructor of other protocols
3980 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3981 work started with create_connection() and timeout in httplib, and
3982 closes patch #723312.
3983

3985 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003986 and HTTPSConnection now accept an optional timeout).

4008
Georg Brandlf66b6032007-03-14 08:27:52 +00004009- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004010 AttributeError instead of an IOError when the server's response
4011 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004012

Georg Brandl3ee81df2008-05-17 18:14:43 +00004017- Patch #1429539: pdb now correctly initializes the __main__ module
4018 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004019 correctly now.
4020

4027
Georg Brandl3ee81df2008-05-17 18:14:43 +00004028- Patch #1530482: add pydoc.render_doc() which returns the

4038 parameter which can be set to False to prevent the default
4039 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00004040
Georg Brandl9e6b4702007-03-13 18:15:41 +00004041- Patch #1581073: add a flag to textwrap that prevents the dropping of
4042 whitespace while wrapping.
4043
Georg Brandl92a6bae2007-03-13 17:43:32 +00004044- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045 are set for invalid interpolation sequences that would lead to
4046 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004047

4089 returned string up to the first NUL character.

4100
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101- unittest now verifies more of its assumptions. In particular,
4102 TestCase and TestSuite subclasses (not instances) are no longer
4103 accepted in TestSuite.addTest(). This should cause no
4104 incompatibility since it never made sense with ordinary subclasses
4105 -- the failure just occurred later, with a more cumbersome
4106 exception.

4116
Georg Brandl3ee81df2008-05-17 18:14:43 +00004117- Patch #1673619: setup.py identifies extension modules it doesn't

4466 contents before adding elements from the iterable. This fix brings
4467 the behavior into line with that for list.__init__().

4477 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Georg Brandl3ee81df2008-05-17 18:14:43 +00004495 time so that opening a database previously created with the DB_DUP
4496 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4497 opens. Specifically: dictionary assignment to a DB object will
4498 replace all values for a given key when the database allows
4499 duplicate values. DB users should use DB.put(k, v) when they want
4500 to store duplicates; not DB[k] = v.

4507 characters with ASCII value less than 32. Also, it correctly quotes
4508 dots only if they occur on a single line, as opposed to the previous
4509 behavior of quoting dots if they are the second character of any
4510 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004511

Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4889 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
