12Core and Builtins
13-----------------
14
Antoine Pitrou0a7b65b2010-09-08 12:40:49 +000015- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
16 thread-local storage key.
17
Victor Stinnercaafd772010-09-08 10:51:01 +000018- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
19 encoding and errors attributes instead of using utf-8 in strict mode, to get
20 the same behaviour than the print statement.
21
Antoine Pitrou9cf85f12010-09-01 21:17:34 +000022- Issue #9737: Fix a crash when trying to delete a slice or an item from
23 a memoryview object.
24
Martin v. Löwis6086b0d2010-08-19 09:09:04 +000025- Restore GIL in nis_cat in case of error.
26
Benjamin Peterson6f3d6a92010-08-25 23:17:42 +000027- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
28
Florent Xicluna172e15f2010-08-09 20:02:00 +000029- Issue #8530: Prevent stringlib fastsearch from reading beyond the front
30 of an array.
31
Raymond Hettinger3ad323e2010-08-06 10:18:56 +000032- Issue #83755: Implicit set-to-frozenset conversion was not thread-safe.
33
Mark Dickinsonaad57bd2010-08-01 10:45:15 +000034- Issue #9416: Fix some issues with complex formatting where the
35 output with no type specifier failed to match the str output:
36
37 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
38 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
39
Antoine Pitrou32669782010-07-11 12:14:05 +000040- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
41 compiler.

43Library
44-------
45
Antoine Pitrou6391b342010-09-14 18:48:19 +000046- Issue #9854: The default read() implementation in io.RawIOBase now
47 handles non-blocking readinto() returning None correctly.
48
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000049- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
50 SSLSocket.sendto() to match the corresponding socket methods. Also,
51 fix various SSLSocket methods to raise socket.error rather than an
52 unhelpful TypeError when called on an unconnected socket. Original patch
53 by Andrew Bennetts.
54
Raymond Hettinger74f869e2010-09-13 22:14:36 +000055- Issue #9826: OrderedDict.__repr__ can now handle self-referential
56 values: d['x'] = d.
57
Victor Stinner46287f52010-09-13 20:31:34 +000058- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X
59 (macpath module).
60
Antoine Pitroue4195e82010-09-12 14:56:27 +000061- Issue #9837: The read() method of ZipExtFile objects (as returned by
62 ZipFile.open()) could return more bytes than requested.
63
Raymond Hettinger20397532010-09-12 02:11:45 +000064- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
65 This prevents user-created self-referencing ordered dictionaries from
66 becoming permanently uncollectable GC garbage. The downside is that
67 removing __del__ means that the internal doubly-linked list has to wait for
68 GC collection rather than freeing memory immediately when the refcnt drops
69 to zero.
70
Raymond Hettingerffd2a422010-09-10 10:47:22 +000071- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
72 different internal state for small values of n. Fixed by salting the
73 value.
74
Antoine Pitrouc818ed42010-09-07 21:40:25 +000075- Issue #9792: In case of connection failure, socket.create_connection()
76 would swallow the exception and raise a new one, making it impossible
77 to fetch the original errno, or to filter timeout errors. Now the
78 original error is re-raised.
79
Antoine Pitrouf4f61712010-09-07 16:34:47 +000080- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
81 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
82 be updated back after the system call. Original patch by Brian Brazil.
83
Antoine Pitroudca9de92010-09-04 17:52:26 +000084- Issue #1100562: Fix deep-copying of objects derived from the list and
85 dict types. Patch by Michele Orrù and Björn Lindqvist.
86
Fred Drakea1e627d2010-09-03 03:55:50 +000087- Issue #7005: Fixed output of None values for RawConfigParser.write and
88 ConfigParser.write.
89
Daniel Stutzbach66c981b2010-08-31 20:29:39 +000090- Issue #808164: Fixed socket.close to avoid references to globals, to
91 avoid issues when socket.close is called from a __del__ method.
92
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +000093- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
94 falling into recursion.
95
R. David Murray7c4bf552010-08-25 01:45:57 +000096- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
97 character years even if the message contains RFC822 two character years.
98
Daniel Stutzbach91287322010-08-24 21:09:30 +000099- Issue #8750: Fixed MutableSet's methods to correctly handle
100 reflexive operations, namely x -= x and x ^= x.
101
Victor Stinnercaafd772010-09-08 10:51:01 +0000102- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000103 error handling when accepting a new connection.
104
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000105- Issue #658749: asyncore's connect() method now correctly interprets winsock
106 errors.
107
Vinay Sajip1ddd51f2010-08-23 17:50:30 +0000108- Issue #9501: Fixed logging regressions in cleanup code.
109

111 module now correctly return a set. (Patch by Eli Bendersky.)
112
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000113- Issue #9617: Signals received during a low-level write operation aren't
114 ignored by the buffered IO layer anymore.
115
Benjamin Peterson52c36052010-08-21 03:03:22 +0000116- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
117 are not held onto after they are deleted elsewhere.
118
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000119- Issue #9626: the view methods for collections.OrderedDict() were returning
120 the unordered versions inherited from dict. Those methods are now
121 overridden to provide ordered views.
122
Éric Araujo0389ae62010-08-14 03:07:46 +0000123- Issue #8688: MANIFEST files created by distutils now include a magic
124 comment indicating they are generated. Manually maintained MANIFESTs
125 without this marker will not be overwritten or removed.
126
Antoine Pitroue1436d12010-08-12 15:25:51 +0000127- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
128 and a BadZipfile error is raised if it doesn't match (as used to be the
129 case in Python 2.5 and earlier).
130
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000131- Issue #9550: a BufferedReader could issue an additional read when the
132 original read request had been satisfied, which could block indefinitely
133 when the underlying raw IO channel was e.g. a socket. Report and original
134 patch by Jason V. Miller.
135
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000136- Issue #9551: Don't raise TypeError when setting the value to None for

140 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
141
Antoine Pitrou99009162010-08-09 22:51:24 +0000142- Issue #3757: thread-local objects now support cyclic garbage collection.
143 Thread-local objects involved in reference cycles will be deallocated
144 timely by the cyclic GC, even if the underlying thread is still running.
145
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000146- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

Senthil Kumarane677ecf2010-08-08 11:56:31 +0000154- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
155 This is how it is supposed to work, wget and curl do the same. Previous
156 behavior was wrong.
157
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +0000158- Issue #2944: asyncore doesn't handle connection refused correctly.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000489- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
490 start byte and the continuation byte(s) are now considered invalid, instead
491 of the number of bytes specified by the start byte.
492 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
493 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
494 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

504 objects. (1) The comparison could incorrectly return True in some cases
505 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

648 non-float non-integer argument is now converted to an integer (if possible)

703 trapped, the specification determines the order in which the signals should be

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000871
872Core and Builtins
873-----------------
874
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000875- Issue #7301: Add environment variable $PYTHONWARNINGS.
876
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000877- Issue #8329: Don't return the same lists from select.select when no fds are
878 changed.
879
Georg Brandlfee0f442010-05-22 21:26:21 +0000880- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000881 on 64-bit machines. The shift count for either left or right shift is
882 permitted to be up to sys.maxsize.
883
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000884- Ensure that tokenization of identifiers is not affected by locale.
885
Georg Brandlfee0f442010-05-22 21:26:21 +0000886- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000887
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000888- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
889
Georg Brandlfee0f442010-05-22 21:26:21 +0000890- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
891 with a non-empty format string. This is an effort to future-proof user
892 code. If a derived class does not currently implement __format__ but later
893 adds its own __format__, it would most likely break user code that had
894 supplied a format string. This will be changed to a DeprecationWaring in
895 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000896
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000897- Issue #8268: Old-style classes (not just instances) now support weak
898 references.
899
Georg Brandlfee0f442010-05-22 21:26:21 +0000900- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
901 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +0000902
Victor Stinnerc7790ed2010-03-22 12:36:28 +0000903- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +0000904
Benjamin Peterson96545892010-03-21 20:21:00 +0000905- Issue #6474: Make error message from passing an inadequate number of keyword
906 arguments to a function correct.
907
Benjamin Peterson0dee9c12010-03-17 20:41:42 +0000908- Issue #8164: Don't allow lambda functions to have a docstring.
909
Victor Stinner66644262010-03-10 22:30:19 +0000910- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +0000911 (SIGINT). If an error occurs while importing the site module, the error is
912 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000913 module.

921
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000922- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000923 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
924 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000925
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000926- Issue #8310: Allow dis to examine new style classes.
927
Georg Brandlfee0f442010-05-22 21:26:21 +0000928- Issue #8257: The Decimal construct now accepts a float instance directly,
929 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000930
931 >>> Decimal(1.1)
932 Decimal('1.100000000000000088817841970012523233890533447265625')
933
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000934- collections.Counter() now supports a subtract() method.
935
Georg Brandlfee0f442010-05-22 21:26:21 +0000936- The functools module now has a total_ordering() class decorator to simplify
937 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000938
Georg Brandlfee0f442010-05-22 21:26:21 +0000939- The functools module also adds cmp_to_key() as a tool to transition old-style
940 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000941
Georg Brandlfee0f442010-05-22 21:26:21 +0000942- Issue #8294: The Fraction constructor now accepts Decimal and float instances
943 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000944
Georg Brandlfee0f442010-05-22 21:26:21 +0000945- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
946 InvalidOperation instead of returning False. (Comparisons involving a quiet
947 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
948 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000949
Georg Brandlfee0f442010-05-22 21:26:21 +0000950- Issue #2531: Comparison operations between floats and Decimal instances now
951 return a result based on the numeric values of the operands; previously they
952 returned an arbitrary result based on the relative ordering of id(float) and
953 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000954
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000955- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000956 argument `-` which tells it to read files to compile from stdin. Each line is
957 read on demand and the named file is compiled immediately. (Original patch by
958 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000959
Georg Brandlfee0f442010-05-22 21:26:21 +0000960- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000963- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
964 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000965 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000966
Georg Brandlfee0f442010-05-22 21:26:21 +0000967- Comparisons using one of <, <=, >, >= between a complex instance and a
968 Fractions instance now raise TypeError instead of returning True/False. This
969 makes Fraction <=> complex comparisons consistent with int <=> complex, float
970 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000971
Michael Foorde6410c52010-03-29 20:04:23 +0000972- Addition of ``WeakSet`` to the ``weakref`` module.

980
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000981- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000982 didn't support chflags() (for example ZFS under FreeBSD). The error is now
983 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000984
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000985- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
986 deprecated.
987
Georg Brandlfee0f442010-05-22 21:26:21 +0000988- Issue #7860: platform.uname now reports the correct 'machine' type when Python
989 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +0000990

995 existing at the same time, causing a Unicode error when configuration code
996 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +0000997
Georg Brandlfee0f442010-05-22 21:26:21 +0000998- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
999 when logging occurs.

Antoine Pitroueee91cd2010-03-26 19:27:16 +00001001- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
1002 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1003 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00001004
Florent Xiclunacf82fa62010-03-21 12:27:20 +00001005- Issue #8179: Fix macpath.realpath() on a non-existing path.

Matthias Klose358e7ff2010-03-15 13:42:23 +00001020
Georg Brandlfee0f442010-05-22 21:26:21 +00001021- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set
1022 to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +00001023 program name.
Victor Stinner75227342010-03-12 14:30:26 +00001024
Vinay Sajipecfa08f2010-03-12 09:16:10 +00001025- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001026 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1027 log file to compute the next rollover time. If the log file does not exist,
1028 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001029
Georg Brandlba83f822010-03-14 09:50:54 +00001030- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001038- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1039 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1040 This is a behavior change, so email's minor version number is now bumped, to
1041 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001069- Issue #8300: When passing a non-integer argument to struct.pack with any
1070 integer format code, struct.pack first attempts to convert the non-integer
1071 using its __index__ method. If that method is non-existent or raises

1073
Georg Brandlba83f822010-03-14 09:50:54 +00001074- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1075 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1076 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001077 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1078 inconsistent: __int__ was used for some integer codes but not for others, and
1079 the set of integer codes for which it was used differed between native packing
1080 and standard packing.)

1482
Georg Brandlba83f822010-03-14 09:50:54 +00001483- The ``__complex__()`` method is now looked up on the class of instances to
1484 make it consistent with other special methods.

1488
Mark Dickinson1b34d252010-01-01 17:27:30 +00001489- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001490 DeprecationWarning when passed a float argument where an integer was expected.
1491 These functions and methods now raise TypeError instead. The majority of the
1492 effects of this change are in the extension modules, but some core functions
1493 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1494 and many unicode/str methods.

1508 of integers: the result of a/b is now correctly rounded for ints a and b (at
1509 least on IEEE 754 platforms), and in particular does not depend on the
1510 internal representation of a long.

1518
Georg Brandlba83f822010-03-14 09:50:54 +00001519 These executables now work properly with the arch(1) command: ``arch -ppc

1661 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001662
Georg Brandlba83f822010-03-14 09:50:54 +00001663- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1664 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00001677- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1678 decimal string that's guaranteed to round back to x under correct rounding
1679 (with round-half-to-even rounding mode). Previously it gave a string based on
1680 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1681 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1682 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001683
Georg Brandlba83f822010-03-14 09:50:54 +00001684- Issue #7117: On almost all platforms: float-to-string and string-to-float
1685 conversions within Python are now correctly rounded. Places these conversions
1686 occur include: str for floats and complex numbers; the float and complex
1687 constructors; old-style and new-style numeric formatting; serialization and
1688 deserialization of floats and complex numbers using marshal, pickle and json;
1689 parsing of float and imaginary literals in Python code; Decimal-to-float
1690 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001691
Georg Brandlba83f822010-03-14 09:50:54 +00001692 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1693 providing correctly-rounded strtod and dtoa C functions. This code is
1694 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1695 the C compiler. There may be a small number of platforms on which correct
1696 operation of this code cannot be guaranteed, so the code is not used: notably,
1697 this applies to platforms where the C double format is not IEEE 754 binary64,
1698 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1699 and Python's configure script is unable to determine how to change the FPU
1700 precision. On these platforms conversions use the platform strtod and dtoa,
1701 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001703- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1704 uses the correctly-rounded string <-> float conversions described above (when
1705 available), and so produces correctly rounded results that will display nicely
1706 under the float repr. There are two related small changes: (1) round now
1707 accepts any class with an ``__index__()`` method for its second argument (but
1708 no longer accepts floats for the second argument), and (2) an excessively
1709 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1710 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001852
Georg Brandlba83f822010-03-14 09:50:54 +00001853 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1854 (2) parsing of strings representing infinities and nans was locale aware; and
1855 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001857- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1858 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1859 but with at least one decimal point and with a default precision
1860 of 12. Previously, the behavior the same but with a default precision of 6.
1861 This more closely matches ``str()``, and reduces surprises when adding
1862 alignment flags to the empty presentation type. This also affects the new
1863 complex.__format__ in the same way.
1864
1865- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1866 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001928 untrackable objects are not tracked by the garbage collector. This can reduce

1937 internal representation of integers, for performance reasons. Base 2**30 is
1938 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00002046- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2047 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2048 instances. On a typical machine this saves 3 bytes of memory (on average) per
2049 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002051- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2054
Georg Brandlba83f822010-03-14 09:50:54 +00002055- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2060
Georg Brandlba83f822010-03-14 09:50:54 +00002061- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2062 file objects with closefd=False. The file descriptor is still kept open but
2063 the file object behaves like a closed file. The ``FileIO`` object also got a
2064 new readonly attribute ``closefd``.

2083
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002084- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002087- On windows, ``os.chdir()`` given unicode was not working if
2088 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2089 this code path is really executed because I cannot move to such directory on
2090 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002092- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2093 element is temporarily replaced with an equivalent frozenset. But the
2094 eventual KeyError would always report the empty ``frozenset()`` as the missing
2095 key. Now it correctly refers to the initial element.

2114
Walter Dörwalded960ac2009-05-03 22:36:33 +00002115- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2116 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2117 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2118 of using the replace error handler in PyUnicode_DecodeUTF8().
2119
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002120- Issue #3739: The unicode-internal encoder now reports the number of characters
2121 consumed like any other encoder (instead of the number of bytes).
2122
Georg Brandlba83f822010-03-14 09:50:54 +00002123- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2124 allocator will be automatically disabled when running under Valgrind. This
2125 gives improved memory leak detection when running under Valgrind, while taking
2126 advantage of pymalloc at other times.

3492
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003493- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3494 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3495 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3496 ``printf`` function, whereas PyString_FromFormat has an independent
3497 implementation and uses "%zd" on all platforms for size_t values.
3498 This makes a difference on win64, where ``printf`` needs "%Id" to display
3499 64bit values.

3505 object; previously an int would be returned for small values. the __long__
3506 method is allowed to return either an int or a long, but the behaviour of
3507 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003509- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00003515 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003516 was correctly parsed but parsing of subsequent arguments failed.
3517
Vinay Sajip35e3b032008-09-01 14:33:59 +00003518- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003519 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3520 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3521 when given a tuple of classes as second argument, were looking up
3522 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3523 type object.
3524
Neal Norwitz18aa3882008-08-24 05:04:52 +00003525- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003594 warnings.catch_warnings() along with some API cleanup. Expanding the tests

3669
Guido van Rossumf8402962008-08-20 15:01:50 +00003670- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3671 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3672 extensions do not automatically benefit from the class attribute
3673 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3674 to their tp_flags field if they care. This is a backwards
3675 compatibility feature; in 3.0, all types will use the cache by
3676 default.
3677
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003678- Keyword arguments can now follow starred arguments. (``f(a, *args,
3679 keyword=23)`` is now valid syntax.)
3680
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003681- ctypes function pointers that are COM methods have a boolean True
3682 value again.

Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003694- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3695 (64bit Unix, for example), unichr() would truncate its argument and return
3696 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

3701 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3702
Antoine Pitrou92f82162008-07-25 22:22:08 +00003703- Issue #1819: function calls with several named parameters are now on
3704 average 35% faster (as measured by pybench).
3705
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003706- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3707 the python debugger steps into a class statement: the free variables (local
3708 variables defined in an outer scope) would be deleted from the outer scope.
3709
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003710- Issue #2620: Overflow checking when allocating or reallocating memory
3711 was not always being done properly in some python types and extension
3712 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3713 all been updated to perform better checks and places in the code that
3714 would previously leak memory on the error path when such an allocation
3715 failed have been fixed.

3721
Benjamin Petersone977ad42008-08-20 01:42:01 +00003722- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3723 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3724
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003725- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3726 version reported by these tools does not necessarily follow the python
3727 version numbering scheme, so the module is less strict when parsing it.
3728
Nick Coghlanf70385a2008-08-18 12:42:46 +00003729- Issue #2235: Added Py3k warnings for types which will become unhashable
3730 under the stricter __hash__ inheritance rules in 3.0. Several types
3731 which did not meet the rules for hash invariants and were already
3732 unhashable in 3.0 have now been explicitly flagged as unhashable in
3733 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3734 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3735
Brett Cannon88f801d2008-08-18 00:46:22 +00003736- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3737 imported into the module but exposed as part of the module's API.
3738

3758 after a 302 response in the case of not going through a proxy.
3759
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003760- Issue #2676: in the email package, content-type parsing was hanging on
3761 pathological input because of quadratic or exponential behaviour of a
3762 regular expression.
3763
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003764- Issue #3476: binary buffered reading through the new "io" library is now
3765 thread-safe.
3766
Brett Cannonbf3157b2008-08-14 05:00:03 +00003767- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3768 since mimetools itself is deprecated. Because modules are cached, all
3769 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3770
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003771- Issue #3134: shutil referenced undefined WindowsError symbol.

3774 menu entries were not deleted.
3775
Brett Cannon83e81842008-08-09 23:30:55 +00003776- Copied the implementation of reduce() to _functools.reduce() to have a

3778
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003779- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3780 a MemoryError rather than silently stop the iteration.
3781
Guido van Rossum59ce9012008-08-09 14:55:34 +00003782- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3783 to _sre.compile() will now be rejected. This should not affect anybody
3784 since the re.compile() function never generates invalid re-bytecode.
3785
Skip Montanaroa032bf42008-08-08 22:52:51 +00003786- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3787 upon first access it can be automatically initialized from the csv file if
3788 it wasn't initialized during instantiation.
3789
Brett Cannon3aa2a492008-08-06 22:28:09 +00003790- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3791 the reload() built-in has been removed.
3792
Brett Cannon7e30b672008-08-04 21:52:25 +00003793- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003794 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3802 raised an AttributeError.
3803
Benjamin Peterson01a24322008-07-28 23:35:27 +00003804- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003805 asking for a specific length. This problem only affected files opened
3806 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003807

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003831- Issue #3394: zipfile.writestr sets external attributes when passed a
3832 file name rather than a ZipInfo instance, so files are extracted with
3833 mode 0600 rather than 000 under Unix.
3834
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003835- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3836 argument in python 2.5, this broke code that subclassed Popen to include its
3837 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003847- Issue #2235: the C API function PyObject_HashNotImplemented and its
3848 interaction with the tp_hash slot (added in 2.6b2) are now documented
3849
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003850- Issue #643841: The language reference now provides more detailed
3851 coverage of the lookup process for special methods. The disclaimers
3852 regarding lack of coverage of new-style classes have also been
3853 removed, since the coverage is now fairly reasonable.

3857================================
3858
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003859*Release date: 17-Jul-2008*
3860
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003861Core and Builtins
3862-----------------
3863
Georg Brandl3e483f62008-07-16 22:57:41 +00003864- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3865 its methods now allow for items objects that can be converted to
3866 an integer using operator.index().
3867
Mark Dickinson64b7e502008-07-16 09:40:03 +00003868- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3869 produced a ValueError instead of giving the correct float.
3870
Eric Smitha5fa5a22008-07-16 00:11:49 +00003871- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3872 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3873
Mark Dickinson7103aa42008-07-15 19:08:33 +00003874- Issue #3008: the float type has a new instance method 'float.hex'
3875 and a new class method 'float.fromhex' to convert floating-point
3876 numbers to and from hexadecimal strings, respectively.
3877
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003878- Issue #2235: __hash__ is once again inherited by default. To allow
3879 collections.Hashable to remain meaningful in the presence of the
3880 default hash implementation (object.__hash__), it is now possible
3881 to explicit block inheritance of hash by setting __hash__=None at
3882 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3883 level.
3884
Nick Coghlanb028f502008-07-13 14:52:36 +00003885- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3886 the parent module cannot be found while performing an absolute import.
3887 This means that an incorrectly defined __package__ attribute will
3888 now only prevent relative imports in that module rather than causing
3889 all imports from that module to fail.
3890
Nick Coghlan14ff9942008-07-08 14:21:42 +00003891- Issue #2517: Allow unicode messages in Exceptions again by correctly
3892 bypassing the instance dictionary when looking up __unicode__ on
3893 new-style classes.
3894
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003895- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3896 set to a custom object whose write() method happens to install
3897 another file in sys.stdout.
3898
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003899- Issue #3088: Corrected a race condition in classes derived from
3900 threading.local: the first member set by a thread could be saved in
3901 another thread's dictionary.
3902
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003903- Issue #3004: Minor change to slice.indices(): the start and stop
3904 arguments are now treated identically, making the behaviour easier
3905 to describe and understand. For example, slice(None, -10,
3906 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3907 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3908 10, -1).
3909
Georg Brandl278fc502008-07-19 12:46:12 +00003910- Issue #3219: Calling a function with repeated keyword arguments,
3911 f(a=2, a=23), would not cause a syntax error. This was a regression
3912 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003913
Georg Brandl278fc502008-07-19 12:46:12 +00003914- Issue #2862: Make int and float freelist management consistent with
3915 other freelists. Changes their CompactFreeList apis into
3916 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003917

3919-------
3920
Thomas Heller57adf222008-08-14 19:10:48 +00003921- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3922 api functions without holding the GIL, which could lead to a fatal
3923 error when they failed.
3924
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003925- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003933- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3934 ForkingPickler.register() to resolve conflict with ctypes.
3935
Vinay Sajip51e65192008-07-18 09:01:10 +00003936- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003937
Thomas Heller880f5292008-07-15 19:39:38 +00003938- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3939 a valid dlerror() message.
3940
Thomas Heller2bad6572008-07-15 17:19:50 +00003941- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3942 incomplete structure was created.
3943
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003944- Issue #3339: dummy_thread.acquire() should not return None.

3947
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003948- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003949
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003950- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3951 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003952 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003953 content-length. The problem had been corrected in the 2.4 branch, but never
3954 merged into trunk.
3955
Georg Brandle78fbcc2008-07-05 10:13:36 +00003956- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00003966- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003967 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003968
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003969- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3970 handling is now the same as that of other special attributes like __name__).
3971
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003972- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3973 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004362 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004363
4364 This is controlled by the configure argument ``--with-universal-archs``:
4365
4366 - ``--with-universal-archs=all``: install 4-way universal
4367
4368 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4369
4370 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4371
4372 This option should be used in combination with ``--enable-universalsdk=``.
4373
4374 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004424- Issue #1631171: Re-implement the 'warnings' module in C (the
4425 original Python code has been kept as backup). This will allow for
4426 using the 'warning's machinery in such places as the parser where
4427 use of pure Python code is not possible. Both the ``showarning()``
4428 and ``formatwarning()`` gain an optional 'line' argument which is
4429 not called by default for backwards-compatibility reasons. Setting
4430 ``warnings.showwarning()`` to an implementation that lacks support
4431 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004494- Issue #2550: The approach used by client/server code for obtaining
4495 ports to listen on in network-oriented tests has been refined in an
4496 effort to facilitate running multiple instances of the entire
4497 regression test suite in parallel without issue.
4498 test_support.bind_port() has been fixed such that it will always
4499 return a unique port -- which wasn't always the case with the
4500 previous implementation, especially if socket options had been set
4501 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4502 new implementation of bind_port() will actually raise an exception
4503 if it is passed an AF_INET/SOCK_STREAM socket with either the
4504 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4505 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4506 the socket it's been passed. This currently only applies to
4507 Windows. This option prevents any other sockets from binding to the
4508 host/port we've bound to, thus removing the possibility of the
4509 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4510 when a second SOCK_STREAM socket binds and accepts to a host/port
4511 that's already been bound by another socket. The optional preferred
4512 port parameter to bind_port() has been removed. Under no
4513 circumstances should tests be hard coding ports!
4514
4515 test_support.find_unused_port() has also been introduced, which will
4516 pass a temporary socket object to bind_port() in order to obtain an
4517 unused port. The temporary socket object is then closed and
4518 deleted, and the port is returned. This method should only be used
4519 for obtaining an unused port in order to pass to an external program
4520 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4521 a parameter to a server-oriented class that doesn't give you direct
4522 access to the underlying socket used.
4523
4524 Finally, test_support.HOST has been introduced, which should be used
4525 for the host argument of any relevant socket calls (i.e. bind and
4526 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004527
4528 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004529 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

4531 test_asynchat and test_socket_ssl.
4532
Georg Brandl3ee81df2008-05-17 18:14:43 +00004533 It is now possible for multiple instances of the regression test
4534 suite to run in parallel without issue.

4800Core and builtins
4801-----------------
4802
Fred Drakea8ee94b2008-03-01 02:45:07 +00004803- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004804 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004805
Georg Brandlad61bc82008-02-23 15:11:18 +00004806- Issue #2067: file.__exit__() now calls subclasses' close() method.
4807
4808- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004809
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004810- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004811 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004812
Eric Smitha73fbe72008-02-23 03:09:44 +00004813- Added the future_builtins module, which contains hex() and oct().
4814 These are the PEP 3127 version of these functions, designed to be
4815 compatible with the hex() and oct() builtins from Python 3.0. They
4816 differ slightly in their output formats from the existing, unchanged
4817 Python 2.6 builtins. The expected usage of the future_builtins
4818 module is:
4819 from future_builtins import hex, oct
4820
Eric Smith7ef40bf2008-02-20 23:34:22 +00004821- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4822 exponents for exponents with absolute value < 100. Follows C99
4823 standard. This is a change on Windows, which would use 3 digits.
4824 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4825 so that any alterations it does to the resulting string will be
4826 available in stringlib/formatter.h (for float.__format__).
4827
Eric Smith5a3c1352008-02-19 13:21:56 +00004828- Implemented PEP 3101, Advanced String Formatting. This adds a new
4829 builtin format(); a format() method for str and unicode; a
4830 __format__() method to object, str, unicode, int, long, float, and
4831 datetime; the class string.Formatter; and the C API
4832 PyObject_Format().
4833
Georg Brandl3ee81df2008-05-17 18:14:43 +00004834- Fixed several potential crashes, all caused by specially crafted
4835 __del__ methods exploiting objects in temporarily inconsistent
4836 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004837
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004838- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004839 prevent a possible crash: an Abstract Base Class would try to access
4840 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004841
Georg Brandl3ee81df2008-05-17 18:14:43 +00004842- Fixed repr() and str() of complex numbers with infinity or nan as
4843 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004844
Georg Brandl3ee81df2008-05-17 18:14:43 +00004845- Clear all free lists during a gc.collect() of the highest generation
4846 in order to allow pymalloc to free more arenas. Python may give back
4847 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004848
Georg Brandl3ee81df2008-05-17 18:14:43 +00004849- Issue #2045: Fix an infinite recursion triggered when printing a
4850 subclass of collections.defaultdict, if its default_factory is set
4851 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004852
Christian Heimesf75dbef2008-02-08 00:11:31 +00004853- Fixed a minor memory leak in dictobject.c. The content of the free
4854 list was not freed on interpreter shutdown.
4855
Georg Brandl21e99f42010-03-07 15:23:59 +00004856- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004858
Georg Brandl3ee81df2008-05-17 18:14:43 +00004859- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4860 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004861 to compact the internal free lists of pre-allocted ints and floats.
4862
Georg Brandl3ee81df2008-05-17 18:14:43 +00004863- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4864 calls. Python expected the return type int but the fork familie
4865 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004866
Georg Brandl3ee81df2008-05-17 18:14:43 +00004867- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4868 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004869
Georg Brandl3ee81df2008-05-17 18:14:43 +00004870- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4871 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004872
Georg Brandl3ee81df2008-05-17 18:14:43 +00004873- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4874 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004875
Georg Brandl3ee81df2008-05-17 18:14:43 +00004876- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4877 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004878
Georg Brandl3ee81df2008-05-17 18:14:43 +00004879- Patch #1473257: generator objects gain a gi_code attribute. This is
4880 the same object as the func_code attribute of the function that
4881 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004882
Georg Brandl3ee81df2008-05-17 18:14:43 +00004883- Issue #1920: "while 0" statements were completely removed by the
4884 compiler, even in the presence of an "else" clause, which is
4885 supposed to be run when the condition is false. Now the compiler
4886 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004887
Guido van Rossumeead05f2008-01-24 18:21:02 +00004888- A few crashers fixed: weakref_in_del.py (issue #1377858);
4889 loosing_dict_ref.py (issue #1303614, test67.py);
4890 borrowed_ref_[34].py (not in tracker).
4891
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004892- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004893 suppressed while an extension is loaded by calling SetErrorMode in
4894 dynload_win.c. The error is still reported properly.
4895
Georg Brandl3ee81df2008-05-17 18:14:43 +00004896- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004897 several extension methods and modules do not work without unicode
4898 support.
4899
Georg Brandl26543b12008-01-21 18:36:51 +00004900- Issue #1882: when compiling code from a string, encoding cookies in the
4901 second line of code were not always recognized correctly.
4902
Georg Brandl14404b62008-01-19 19:27:05 +00004903- Issue #1679: "0x" was taken as a valid integer literal.
4904
Georg Brandl6caad7d2008-01-26 14:19:22 +00004905- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004906 added.
4907
Christian Heimesc94e2b52008-01-14 04:13:37 +00004908- sys.float_info / PyFloat_GetInfo: The floating point information
4909 object was converted from a dict to a specialized structseq object.
4910
Georg Brandl3ee81df2008-05-17 18:14:43 +00004911- Patch #1816: Added sys.flags structseq. It exposes the status of
4912 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004913
Georg Brandl3ee81df2008-05-17 18:14:43 +00004914- Objects/structseq.c: Implemented new structseq representation. The
4915 patch makes structseqs (e.g. the return value of os.stat) more
4916 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004917
Georg Brandl3ee81df2008-05-17 18:14:43 +00004918- Patch #1700288: added a type attribute cache that caches method
4919 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004920
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004921- Bug #1776: __import__() no longer accepts filenames on any platform.
4922 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004923
Georg Brandlaed6c662008-01-07 17:25:53 +00004924- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4925
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4927 envvar and sys.dont_write_bytecode attribute. All these can be set
4928 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004929
Georg Brandl3ee81df2008-05-17 18:14:43 +00004930- Improve some exception messages when Windows fails to load an
4931 extension module. Now we get for example '%1 is not a valid Win32
4932 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004933
Georg Brandl3ee81df2008-05-17 18:14:43 +00004934- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004936- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4937 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004938
Christian Heimes0a8143f2007-12-18 23:22:54 +00004939- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004940 and INF. float("nan"), float("inf") and float("-inf") now work on
4941 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004942
Georg Brandl3ee81df2008-05-17 18:14:43 +00004943- Compiler now generates simpler and faster code for dictionary
4944 literals. The oparg for BUILD_MAP now indicates an estimated
4945 dictionary size. There is a new opcode, STORE_MAP, for adding
4946 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004947
Georg Brandl3ee81df2008-05-17 18:14:43 +00004948- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004953- Issue #1538: Avoid copying string in split/rsplit if the split char
4954 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004955
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004956- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004957 SystemError.
4958
Nick Coghlanef01d822007-12-03 12:55:17 +00004959- PEP 366: Allow explicit relative imports when executing modules

4961 __package__ attribute.
4962
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963- Issue #1402: Fix a crash on exit, when another thread is still
4964 running, and if the deallocation of its frames somehow calls the
4965 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004966

4976 file can now be directly executed by passing their name to the
4977 interpreter. The directory/zipfile is automatically inserted as the
4978 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004979
Georg Brandl3ee81df2008-05-17 18:14:43 +00004980- Issue #1265: Fix a problem with sys.settrace, if the tracing
4981 function uses a generator expression when at the same time the
4982 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004983
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004984- sets and frozensets now have an isdisjoint() method.
4985
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004986- optimize the performance of builtin.sum().
4987
Neal Norwitz44f326e2007-10-05 05:29:17 +00004988- Fix warnings found by the new version of the Coverity checker.
4989
Georg Brandl21e99f42010-03-07 15:23:59 +00004990- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004991 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4992 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004993
Georg Brandl3ee81df2008-05-17 18:14:43 +00004994- Issue #1686386: Tuple's tp_repr did not take into account the
4995 possibility of having a self-referential tuple, which is possible
4996 from C code. Nor did object's tp_str consider that a type's tp_str
4997 could do something that could lead to an inifinite recursion.
4998 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4999 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005000
Georg Brandl3ee81df2008-05-17 18:14:43 +00005001- Issue #1164: It was possible to trigger deadlock when using the
5002 'print' statement to write to a file since the GIL was not released
5003 as needed. Now PyObject_Print() does the right thing along with
5004 various tp_print implementations of the built-in types and those in
5005 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005006
Georg Brandl3ee81df2008-05-17 18:14:43 +00005007- Issue #1147: Exceptions were directly allowing string exceptions in
5008 their throw() method even though string exceptions no longer
5009 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005010

Brett Cannon1e534b52007-09-07 04:18:30 +00005014- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005015 PyObject_Call() never calling back out to Python code to trigger
5016 recursion depth updates/checks. Required the creation of a static
5017 RuntimeError instance in case normalizing an exception put the
5018 recursion check value past its limit. Fixes crashers
5019 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005020

Neal Norwitz0ac60192007-05-27 04:08:54 +00005034- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005035 __*__ attributes. (Some already existed, e.g., __doc__ and
5036 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005037
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005038- Add -3 option to the interpreter to warn about features that are

5042 calls.
5043
Collin Winter62903052007-05-18 23:11:24 +00005044- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005045 "except E as target:". This is to provide forwards compatibility
5046 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005047
Brett Cannon229cee22007-05-05 01:34:02 +00005048- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005050- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005051 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005053- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005054 setting a plain string, ie don't expand to single letter identifiers.
5055
Raymond Hettinger13936692007-04-11 18:40:58 +00005056- Request #1191699: Slices can now be pickled.

5066
Guido van Rossum143b5642007-03-23 04:58:42 +00005067- Bug #1683368: The object.__init__() and object.__new__() methods are
5068 now stricter in rejecting excess arguments. The only time when
5069 either allows excess arguments is when it is not overridden and the
5070 other one is. For backwards compatibility, when both are
5071 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005072 warning later). Also, type.__init__() insists on the same signature
5073 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005074
Georg Brandl3ee81df2008-05-17 18:14:43 +00005075- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5076 object to complex using its __complex__() method before falling back
5077 to the __float__() method. Therefore, the functions in the cmath
5078 module now can operate on objects that define a __complex__()
5079 method.

5096
Georg Brandl7b9c5552007-03-12 14:30:05 +00005097- Bug #1678647: write a newline after printing an exception in any
5098 case, even when converting the value to a string failed.
5099
Georg Brandl871f1bc2007-03-12 13:17:36 +00005100- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005101 its argument, if it exists. If not, it will work like before. This
5102 allows customizing the output of dir() in the presence of a
5103 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005104
Collin Winter276887b2007-03-12 16:11:39 +00005105- Patch #922167: Python no longer segfaults when faced with infinitely
5106 self-recursive reload() calls (as reported by bug #742342).

5112 parthensized forms. This means complex(repr(x)) now works instead of
5113 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005114
Georg Brandlaa2321b2007-03-07 00:40:28 +00005115- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116 makes the filenames the warning module prints much more sensible
5117 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005118

Georg Brandl0fca97a2007-03-05 22:28:08 +00005130- Patch #1674228: when assigning a slice (old-style), check for the
5131 sq_ass_slice instead of the sq_slice slot.
5132
Georg Brandl3ee81df2008-05-17 18:14:43 +00005133- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00005668 AttributeError instead of an IOError when the server's response

5760 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006045- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6046 with RFC 3207 and forgets any knowledge obtained from the server not
6047 obtained from the TLS negotiation itself. Patch contributed by Bill
6048 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006049
Georg Brandl3ee81df2008-05-17 18:14:43 +00006050- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006051 that the SMTP.starttls() caller no longer needs to call ehlo()
6052 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006053 does not claim to support starttls. Adds the
6054 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6135 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6136 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006153 time so that opening a database previously created with the DB_DUP
6154 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6155 opens. Specifically: dictionary assignment to a DB object will
6156 replace all values for a given key when the database allows
6157 duplicate values. DB users should use DB.put(k, v) when they want
6158 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006159

6165 characters with ASCII value less than 32. Also, it correctly quotes
6166 dots only if they occur on a single line, as opposed to the previous
6167 behavior of quoting dots if they are the second character of any
6168 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006169

Georg Brandl3ee81df2008-05-17 18:14:43 +00006498- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6499 to ``PyTuple_SetItem``, it can be used to populate a brand new
6500 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006501
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006502- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006504- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6505 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6506 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006507
6508- Patch #1720595: add T_BOOL to the range of structmember types.
6509
6510- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6511 ``PyFloat_GetInfo()`` to the float API.
6512
Georg Brandl3ee81df2008-05-17 18:14:43 +00006513- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6514 of w# format code incorrectly truncated the length to an int, even
6515 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6516 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006517
Georg Brandl3ee81df2008-05-17 18:14:43 +00006518- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6519 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006521- PEP 3123: Provide forward compatibility with Python 3.0, while
6522 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6523 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006524
Georg Brandl3ee81df2008-05-17 18:14:43 +00006525- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6526 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006527
6528- Patch #1733960: Allow T_LONGLONG to accept ints.
6529
6530- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6531
Christian Heimes000a0742008-01-03 22:16:32 +00006532- Added a new API function ``PyImport_ImportModuleNoBlock``.
6533
Georg Brandl6caad7d2008-01-26 14:19:22 +00006534- Bug #1637022: Prefix AST symbols with _Py_.
6535
6536- Fix some leftovers from the conversion from int to Py_ssize_t
6537 (relevant to strings and sequences of more than 2**31 items).
6538
6539- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6540 outside of pystate.c and should not be necessary.
6541
Georg Brandl3ee81df2008-05-17 18:14:43 +00006542- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6543 absolute imports. In earlier versions they might have used relative
6544 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006545
Georg Brandl3ee81df2008-05-17 18:14:43 +00006546- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6547 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006548
Georg Brandl3ee81df2008-05-17 18:14:43 +00006549- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6550 macro so it can be used as an expression.

6555
Georg Brandl3ee81df2008-05-17 18:14:43 +00006556- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6557 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6558 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6559 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006560
Georg Brandl3ee81df2008-05-17 18:14:43 +00006561- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
6562 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00006572- buildtools now raises a DeprecationWarning.
6573
Georg Brandl3ee81df2008-05-17 18:14:43 +00006574- Removed the macfs module. It had been deprecated since Python 2.5.
6575 This lead to the deprecation of macostools.touched() as it relied
6576 solely on macfs and was a no-op under OS X.
