Benjamin Peterson477ba912011-01-12 15:34:01 +000011- Issue #10892: Don't segfault when trying to delete __abstractmethods__ from a
12 class.
13
Antoine Pitrou3be412d2011-01-07 21:47:02 +000014- Issue #8020: Avoid a crash where the small objects allocator would read
15 non-Python managed memory while it is being modified by another thread.
16 Patch by Matt Bandy.
17
Victor Stinner89e34362011-01-07 18:47:22 +000018- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and
19 all io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python
20 parser translates newlines (\r\n => \n).
21
Martin v. Löwisc83bc3c2011-01-06 19:15:47 +000022- Remove buffer API from stable ABI for now, see #10181.
23
Victor Stinnerb3c9e072011-01-04 02:07:34 +000024- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
25 doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int
26 (length bigger than 2^31-1 bytes).
27
Victor Stinnerdc555402011-01-04 13:15:39 +000028- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and
29 stdprinter.write() clamp the length to 2^31-1 on Windows.
Victor Stinnere6edec22011-01-04 00:29:35 +000030
Amaury Forgeot d'Arca251a852011-01-03 00:19:11 +000031- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()
32 can now handle dates after 2038.
33
Victor Stinner92be9392010-12-28 00:28:21 +000034- Issue #10780: PyErr_SetFromWindowsErrWithFilename() and
35 PyErr_SetExcFromWindowsErrWithFilename() decode the filename from the
36 filesystem encoding instead of UTF-8.
37
Victor Stinnercb428f02010-12-27 20:10:36 +000038- Issue #10779: PyErr_WarnExplicit() decodes the filename from the filesystem
39 encoding instead of UTF-8.
40
Georg Brandl8aa7e992010-12-28 18:30:18 +000041- Add sys.flags attribute for the new -q command-line option.

44-------
45
Antoine Pitrou85f46152011-01-15 16:17:07 +000046- Issue #10916: mmap should not segfault when a file is mapped using 0 as
47 length and a non-zero offset, and an attempt to read past the end of file
48 is made (IndexError is raised instead). Patch by Ross Lagerwall.
49
Ned Deily4ce92b22011-01-15 04:37:12 +000050- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5,
51 rather than the currently problematic Apple-supplied one, when running
52 with the 64-/32-bit installer variant.
53
Victor Stinner5c23b8e2011-01-14 13:05:21 +000054- Issue #4953: cgi.FieldStorage and cgi.parse() parse the request as bytes, not
55 as unicode, and accept binary files. Add encoding and errors attributes to
Victor Stinnerc5982962011-01-14 14:11:45 +000056 cgi.FieldStorage. Patch written by Pierre Quentel (with many inputs by Glenn
57 Linderman).
Victor Stinner5c23b8e2011-01-14 13:05:21 +000058
Victor Stinnerac71c542011-01-14 12:52:12 +000059- Add encoding and errors arguments to urllib.parse_qs() and urllib.parse_qsl()
60

62 Removed function type annotations from _pyio.py.
63
Terry Reedyaacfd4a2011-01-10 21:27:49 +000064- Issue #10875: Update Regular Expression HOWTO; patch by 'SilentGhost'.
65
Antoine Pitroua4815ca2011-01-09 20:38:15 +000066- Issue #10872: The repr() of TextIOWrapper objects now includes the mode
67 if available.
68
Georg Brandl619e7ba2011-01-09 07:38:51 +000069- Issue #10869: Fixed bug where ast.increment_lineno modified the root
70 node twice.
71
R. David Murray5b2d9dd2011-01-09 02:35:24 +000072- Issue #5871: email.header.Header.encode now raises an error if any
73 continuation line in the formatted value has no leading white space
74 and looks like a header. Since Generator uses Header to format all
75 headers, this check is made for all headers in any serialized message
76 at serialization time. This provides protection against header
77 injection attacks.
78
Antoine Pitrou67b212e2011-01-08 09:55:31 +000079- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially
80 private by renaming it to ``_GeneratorContextManager``.
81
Raymond Hettinger23f9fc32011-01-08 07:01:56 +000082- Issue #10042: Fixed the total_ordering decorator to handle cross-type
83 comparisons that could lead to infinite recursion.
84
R. David Murray92532142011-01-07 23:25:30 +000085- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
86 non-ASCII bytes (parsed by a Bytes Parser) when doing conversion to
87 7bit-clean presentation, instead of replacing them with ?s.
88
R. David Murray6f0022d2011-01-07 21:57:25 +000089- email.header.Header was incorrectly encoding folding white space when
90 rfc2047-encoding header values with embedded newlines, leaving them
91 without folding whitespace. It now uses the continuation_ws, as it
92 does for continuation lines that it creates itself.
93
Victor Stinner3ec899f2011-01-08 16:37:47 +000094- Issue #1777412, #10827: Changed the rules for 2-digit years. The
95 time.asctime(), time.ctime() and time.strftime() functions will now format
96 any year when ``time.accept2dyear`` is False and will accept years >= 1000
97 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
98 supported by the OS. With Visual Studio or on Solaris, the year is limited to
99 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +0000100
Antoine Pitroue85da7a2011-01-06 18:25:55 +0000101- Issue #7858: Raise an error properly when os.utime() fails under Windows
102 on an existing file.
103
Antoine Pitroub715fac2011-01-06 17:17:04 +0000104- Issue #3839: wsgiref should not override a Content-Length header set by
105 the application. Initial patch by Clovis Fabricio.
106
Victor Stinner4bd81722011-01-06 00:49:38 +0000107- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
108 compilation (if the input is a string).
109
Antoine Pitrou600232b2011-01-05 21:03:42 +0000110- Issue #7995: When calling accept() on a socket with a timeout, the returned
Antoine Pitroudc51a3c2011-01-05 22:43:26 +0000111 socket is now always blocking, regardless of the operating system.
Antoine Pitrou600232b2011-01-05 21:03:42 +0000112
Victor Stinner8786d3d2011-01-05 03:56:22 +0000113- Issue #10756: atexit normalizes the exception before displaying it. Patch by
114 Andreas Stührk.
Victor Stinner358e11d2011-01-05 03:54:25 +0000115
R. David Murray477efb32011-01-05 01:39:32 +0000116- Issue #10790: email.header.Header.append's charset logic now works correctly
117 for charsets whose output codec is different from its input codec.
118
Victor Stinnerc3a51ec2011-01-04 11:00:45 +0000119- Issue #10819: SocketIO.name property returns -1 when its closed, instead of
120 raising a ValueError, to fix repr().
121
Victor Stinner8848c7a2011-01-04 02:07:36 +0000122- Issue #8650: zlib.compress() and zlib.decompress() raise an OverflowError if
123 the input buffer length doesn't fit into an unsigned int (length bigger than
124 2^32-1 bytes).
125
Gregory P. Smith4d419682011-01-03 21:09:23 +0000126- Issue #6643: Reinitialize locks held within the threading module after fork

140 the codec aliases. They are still accessible via codecs.lookup().
141
Georg Brandl5ba11de2011-01-01 10:09:32 +0000142- Issue #10801: In zipfile, support different encodings for the header and

Victor Stinnerf933e1a2010-10-20 22:58:25 +0000726 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +0000727 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +0000728 encoding and to encode command line arguments on this OS.

Georg Brandl27a28582010-10-10 09:49:21 +00001078- ast.literal_eval() can now handle negative numbers. It is also a little more
1079 liberal in what it accepts without compromising the safety of the evaluation.
1080 For example, 3j+4 and 3+4+5 are both accepted.

Georg Brandl27a28582010-10-10 09:49:21 +00001120- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1121 with a non-empty format string. This is an effort to future-proof user
1122 code. If a derived class does not currently implement __format__ but later
1123 adds its own __format__, it would most likely break user code that had
1124 supplied a format string. This will be changed to a DeprecationWaring in
1125 Python 3.3 and it will be an error in Python 3.4.

1129 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001131- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1132 functions from the libc caused the methods .upper() and lower() to become

1140 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).

Georg Brandl27a28582010-10-10 09:49:21 +00001142- Issue #9804: ascii() now always represents unicode surrogate pairs as a single

1144 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1145 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00001180- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001181 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001182 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001183 replacement for old handle_accept() and avoids the user to call accept()

1316 friendlier towards reference cycles. This change is not normally visible
1317 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001319- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1320 still return the id of the parent process after it has exited. This process
1321 id may even have been reused by another unrelated process.
1322
Georg Brandl27a28582010-10-10 09:49:21 +00001323- Issue #9792: In case of connection failure, socket.create_connection() would
1324 swallow the exception and raise a new one, making it impossible to fetch the
1325 original errno, or to filter timeout errors. Now the original error is
1326 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00001328- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
1329 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
1330 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001332- Updates to the random module:
1333
Georg Brandl27a28582010-10-10 09:49:21 +00001334 * Document which parts of the module are guaranteed to stay the same across
1335 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00001337 * Update the seed() method to use all of the bits in a string instead of just
1338 the hash value. This makes better use of the seed value and assures the
1339 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00001340
Georg Brandl27a28582010-10-10 09:49:21 +00001341 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1342 sample(), randrange(), and randint(). Formerly, it used int(n*random())
1343 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00001344
1345 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00001364- hashlib has two new constant attributes: algorithms_guaranteed and

1366 guaranteed to exist in all Python implementations and the names of hash
1367 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00001459- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
1460 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
1461 bytecode is a bit simplified. Patch by Demur Rumed.

Georg Brandl649971e2010-09-05 17:06:50 +00001472- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
1473 now removed, since their effect was inexistent in 3.x (the default encoding is
1474 hardcoded to utf-8 and cannot be changed).

1496 return characters from the full Unicode range, even on narrow unicode builds
1497 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
1498 in Python is that unicodedata.numeric() now returns the correct value for
1499 large code points, and repr() may consider more characters as printable.
1500
Victor Stinner6c00c142010-08-17 23:37:11 +00001501- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00001518 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
1519 objects are output as-is.

1534 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00001535
Georg Brandl649971e2010-09-05 17:06:50 +00001536- Issue #9416: Fix some issues with complex formatting where the output with no
1537 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00001538
1539 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
1540 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Ezio Melotti57221d02010-07-01 07:32:02 +00001879- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00001880 start byte and the continuation byte(s) are now considered invalid, instead of
1881 the number of bytes specified by the start byte. E.g.:
1882 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
1883 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
1884 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
1885 returned a single u'\ufffd'.

Victor Stinner554f3f02010-06-16 23:33:54 +00001905 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00001906 handlers. Patch written by Mark Hammond.

1914
Georg Brandl62069d32010-07-31 08:56:11 +00001915- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00001916 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
1917 location of the raised exception.
1918
Victor Stinner313a1202010-06-11 23:56:51 +00001919- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
1920 filenames and enable os.fsencode().
1921

Georg Brandl62069d32010-07-31 08:56:11 +00001928- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
1929 TypeError instead of giving a DeprecationWarning when a float is parsed using
1930 the 'L' code (for long long). (All other integer codes already raise
1931 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00001932
Victor Stinner600d3be2010-06-10 12:00:55 +00001933- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
1934 enable shortcuts for upper case encoding name. Add also a shortcut for
1935 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
1936
Georg Brandl62069d32010-07-31 08:56:11 +00001937- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
1938 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001939
1940- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00001941 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001942 like bytearray.
1943
Georg Brandl62069d32010-07-31 08:56:11 +00001944- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00001945 used anymore and it was never documented.
1946
Georg Brandl62069d32010-07-31 08:56:11 +00001947- In str.format(), raise a ValueError when indexes to arguments are too large.

Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00001951
Georg Brandl62069d32010-07-31 08:56:11 +00001952- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
1953 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
1954 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
1955 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00001956
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001957- Issue #8748: Fix two issues with comparisons between complex and integer
1958 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001959 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1960 (2) The comparison raised an OverflowError for large integers, leading to
1961 unpredictable exceptions when combining integers and complex objects in sets
1962 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001963
Victor Stinner7d79b8b2010-05-19 20:40:50 +00001964- Issue #8766: Initialize _warnings module before importing the first module.

1966
Victor Stinner9ca9c252010-05-19 16:53:30 +00001967- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00001968 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00001969 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00001970
Georg Brandl62069d32010-07-31 08:56:11 +00001971- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
1972 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00001973
Victor Stinnerae6265f2010-05-15 16:27:27 +00001974- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
1975 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00001976 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00001977 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00001978
Victor Stinner59e62db2010-05-15 13:14:32 +00001979- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00001980 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00001981
Victor Stinnerb744ba12010-05-15 12:27:16 +00001982- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00001983 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00001984 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
1985
Victor Stinner0964ee12010-04-30 16:48:45 +00001986- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00001987 PyUnicode_FromString() to support surrogates in the filename and use the right
1988 encoding.

1995 arguments.
1996
Victor Stinner14284c22010-04-23 12:02:30 +00001997- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute

Mark Dickinsond59b4162010-03-13 11:34:40 +00002038- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
Georg Brandl62069d32010-07-31 08:56:11 +00002039 PyMemberDefs could produce an internal error; raise TypeError instead.
Mark Dickinsond59b4162010-03-13 11:34:40 +00002040
Mark Dickinsonf673f0c2010-03-13 09:48:39 +00002041- Issue #7845: Rich comparison methods on the complex type now return
2042 NotImplemented rather than raising a TypeError when comparing with an
2043 incompatible type; this allows user-defined classes to implement their own
2044 comparisons with complex.

2088 crash in many places because of the PyByteArray_AS_STRING() macro returning
2089 NULL. The macro now returns a statically allocated empty string instead.
Antoine Pitroufc8d6f42010-01-17 12:38:54 +00002090
Antoine Pitroub7fbcd32010-01-16 18:37:38 +00002091- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00002092 where the right hand operand is a set of constants, by turning the set into a
2093 frozenset and pre-building it as a constant. The comparison operation is made
2094 against the constant instead of building a new set each time it is executed (a
2095 similar optimization already existed which turned a list of constants into a
2096 pre-built tuple). Patch and additional tests by Dave Malcolm.
Antoine Pitroub7fbcd32010-01-16 18:37:38 +00002097

2103 including: (1) a serious 'wrong output' bug that could occur for long (> 40
2104 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
2105 parsing certain long numeric strings corresponding to subnormal values, (3) a
2106 memory leak for some values large enough to cause overflow, and (4) a number
2107 of flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +00002108

2116 AttributeError.
2117

Georg Brandl62069d32010-07-31 08:56:11 +00002121- Issue #1811: improve accuracy and cross-platform consistency for true division
2122 of integers: the result of a/b is now correctly rounded for ints a and b (at
2123 least on IEEE 754 platforms), and in particular does not depend on the
2124 internal representation of an int.
Mark Dickinsoncbb62742009-12-27 15:09:50 +00002125
Ronald Oussoren6f6c5622009-12-24 14:03:19 +00002126- Issue #6834: replace the implementation for the 'python' and 'pythonw'
2127 executables on OSX.
2128
Georg Brandl62069d32010-07-31 08:56:11 +00002129 These executables now work properly with the arch(1) command: ``arch -ppc
2130 python`` will start a universal binary version of python in PPC mode (unlike
2131 previous releases).

2149
Georg Brandl62069d32010-07-31 08:56:11 +00002150- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
2151 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
2152 long but the length of the range did not. Also fix several cases where
2153 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
2154 reversed(range(a, b, c)) with large arguments.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00002264- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the

2266 `va_copy`, but available on all python platforms.
2267
Mark Dickinsone6fc7402010-08-06 18:55:26 +00002268- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
2269 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

2292 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
2293 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00002294 to match the behaviour of the other integer format codes.

2323 gives improved memory leak detection when running under Valgrind, while taking
2324 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00002399 simply clearing the entire cache on overflow to forgetting the least recently
2400 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00002401 applications that use a lot of regular expressions and limits the impact of
2402 the performance hit anytime the cache is exceeded.

2416 defined in datetime with fast C impementation. Python implementation is based
2417 on the original python prototype for the datetime module by Tim Peters with
2418 minor modifications by the PyPy project. The test suite now tests `datetime`

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00002775 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00002776 relies on the system threading library, so as to avoid a semi-busy wait loop.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00002800- Add functools.total_ordering() and functools.cmp_to_key().
2801
Georg Brandl62069d32010-07-31 08:56:11 +00002802- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandl62069d32010-07-31 08:56:11 +00002811- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2812 InvalidOperation instead of returning False. (Comparisons involving a quiet
2813 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2814 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00002816- Issue #2531: Comparison operations between floats and Decimal instances now
2817 return a result based on the numeric values of the operands; previously they
2818 returned an arbitrary result based on the relative ordering of id(float) and
2819 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
2820 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00002821
Raymond Hettinger9c01e442010-04-03 10:32:58 +00002822- Added a subtract() method to collections.Counter().
2823
Barry Warsawd5f9bf52010-03-31 21:36:22 +00002824- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00002825 argument `-` which tells it to read files to compile from stdin. Each line is
2826 read on demand and the named file is compiled immediately. (Original patch by
2827 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00002829- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00002833- Comparisons using one of <, <=, >, >= between a complex instance and a
2834 Fractions instance now raise TypeError instead of returning True/False. This
2835 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2836 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou910bd512010-03-22 20:11:09 +00002845- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00002846 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00002879- The internals of the subprocess module on POSIX systems have been replaced by
2880 an extension module (_posixsubprocess) so that the fork()+exec() can be done
2881 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00002883- subprocess.Popen now has restore_signals and start_new_session features. The
2884 default of restore_signals=True is a new behavior compared to earlier Python
2885 versions. This means that signals such as SIGPIPE are not ignored by default
2886 in subprocesses launched by Python (Issue #1652).

Brett Cannonef7d6722010-02-19 16:04:36 +00002944- Issue #7361: Importlib was not properly checking the number of bytes in
2945 bytecode file when it was less then 8 bytes.
2946
Georg Brandl62069d32010-07-31 08:56:11 +00002947- Issue #7633: In the decimal module, Context class methods (with the exception
2948 of canonical and is_canonical) now accept instances of int and long wherever a
2949 Decimal instance is accepted, and implicitly convert that argument to Decimal.
2950 Previously only some arguments were converted.

Georg Brandl62069d32010-07-31 08:56:11 +00002955- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in XML
2956 processing instructions and comments. These raw characters are allowed by the
2957 XML specification, and are necessary when outputting e.g. PHP code in a
2958 processing instruction. Patch by Neil Muller.

2968 specified, rather than fall through to AF_PACKET (in the `socket` module).
Georg Brandl62069d32010-07-31 08:56:11 +00002969 Also, raise ValueError rather than TypeError when an unknown TIPC address type
2970 is specified. Patch by Brian Curtin.

Georg Brandl62069d32010-07-31 08:56:11 +00002972- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
2973 position when calling `truncate()`. It would previously change the file
2974 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00002975 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2976
Antoine Pitroua32f9a22010-01-27 21:18:57 +00002977- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00002978 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
2979 archive. The new implementation is significantly faster and can be wrapped in
2980 a :class:`io.BufferedReader` object for more speedups. It also solves an
2981 issue where interleaved calls to `read()` and `readline()` give wrong results.
2982 Patch by Nir Aides.
Antoine Pitroua32f9a22010-01-27 21:18:57 +00002983
Jesse Noller1f0b6582010-01-27 03:36:01 +00002984- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
Georg Brandl62069d32010-07-31 08:56:11 +00002985 allowing for a maximum number of tasks within the pool to be completed by the
2986 worker before that worker is terminated, and a new one created to replace it.

Benjamin Petersonbf5ff762009-12-13 19:25:34 +00003062- Issue #7349: Make methods of file objects in the io module accept None as an
3063 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
3064 the same as passing no argument.
3065

Tarek Ziadéacafc2d2009-11-29 22:24:57 +00003094- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
3095 ownership when the group is not forced, because the group may be different
3096 from the user's group and inherit from its container when the test is run.

Georg Brandl62069d32010-07-31 08:56:11 +00003141- Issue #6816: runpy now provides a run_path function that allows Python code to
3142 execute file paths that refer to source or compiled Python files as well as
3143 zipfiles, directories and other valid sys.path entries that contain a
3144 __main__.py file. This allows applications that run other Python scripts to
Nick Coghlan260bd3e2009-11-16 06:49:25 +00003145 support the same flexibility as the CPython command line itself.
3146
Georg Brandl62069d32010-07-31 08:56:11 +00003147- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
3148 connection with another process, rather than looping endlessly. The default
3149 timeout is 20 seconds, which should be amply sufficient for local connections.

Antoine Pitrou434736a2009-11-10 18:46:01 +00003162- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00003163 default when instantiating a `threading.RLock` object. This makes recursive
3164 locks as fast as regular non-recursive locks (previously, they were slower by
3165 10x to 15x).

Georg Brandl62069d32010-07-31 08:56:11 +00003380 compared to other unix systems. In particular, os.getgroups() does not reflect

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00003420- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00003421 implementing ``datetime.tzinfo`` interface. Instances of the new class,
3422 ``datetime.timezone``, return fixed name and UTC offset from their
3423 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
3424 returns ``None``. A class attribute, ``utc`` contains an instance
3425 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00003750 runtest_inner in regrtest, with warnings if the called test modifies them, and

3922 (1) inf and nan strings with trailing whitespace were incorrectly
3923 rejected; (2) parsing of strings representing infinities and nans
3924 was locale aware; and (3) the interpretation of fromhex('-nan')
3925 didn't match that of float('-nan').

4028Core and Builtins
4029-----------------
4030
Mark Dickinson865e01a2009-05-07 16:37:01 +00004031- Issue #5914: Add new C API function PyOS_string_to_double, and
4032 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4033
Eric Smith741191f2009-05-06 13:08:15 +00004034- Issue #3382: float.__format__, complex.__format__, and %-formatting
4035 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4036 affects nan -> NAN and inf -> INF.
4037
Mark Hammond5a607a32009-05-06 08:04:54 +00004038- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4039 in all operations, including splitdrive, split, etc. splitunc() now issues
4040 a PendingDeprecation warning.
4041
Eric Smith63376222009-05-05 14:04:18 +00004042- Issue #5920: For float.__format__, change the behavior with the
4043 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4044 to be like 'g' but with at least one decimal point and with a
4045 default precision of 12. Previously, the behavior the same but with
4046 a default precision of 6. This more closely matches str(), and
4047 reduces surprises when adding alignment flags to the empty
4048 presentation type. This also affects the new complex.__format__ in
4049 the same way.
4050
Martin v. Löwis011e8422009-05-05 04:43:17 +00004051- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4052
R. David Murrayb18500d2009-05-04 22:59:07 +00004053- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4054 shadowed by classtype's, even if it was None. property now
4055 inserts the __doc__ into the subclass instance __dict__.
4056
Antoine Pitrou244651a2009-05-04 18:56:13 +00004057- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4058 sequences. Patch by Nick Barnes and Victor Stinner.
4059
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004060- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004061
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004062- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4063 received a new method, detach(). detach() disconnects the underlying stream
4064 from the buffer or text IO and returns it.
4065
Mark Dickinson33841c32009-05-01 15:37:04 +00004066- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4067 floats with absolute value over 1e50. Also remove length
4068 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4069 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004070
Eric Smith741191f2009-05-06 13:08:15 +00004071- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004072 format(complex(1, 2./3), '.5') now produces a sensible result.
4073
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004074- Issue #5864: Fix empty format code formatting for floats so that it
4075 never gives more than the requested number of significant digits.
4076
Eric Smith6dc46f52009-04-27 20:39:49 +00004077- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4078 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4079
Eric Smithcc32a112009-04-26 21:35:14 +00004080- Issue #5835: Deprecate PyOS_ascii_formatd.
4081
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004082- Issue #4971: Fix titlecase for characters that are their own
4083 titlecase, but not their own uppercase.
4084
Benjamin Peterson193152c2009-04-25 01:08:45 +00004085- Issue #5283: Setting __class__ in __del__ caused a segfault.
4086
Mark Dickinsonad476da2009-04-23 19:14:16 +00004087- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4088 z involves nans, infs or negative zeros.
4089
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004090- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004091
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004092- Issue #1869 (and many duplicates): make round(x, n) correctly
4093 rounded for a float x, by using the decimal <-> binary conversions
4094 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4095 consistently agrees with format(x, '.2f').
4096
Benjamin Petersonae937c02009-04-18 20:54:08 +00004097- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4098 some builtin types.
4099
Eric Smith0923d1d2009-04-16 20:16:10 +00004100- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4101
Eric Smith35e84722009-04-16 20:21:28 +00004102- Issue #5515: str.format() type 'n' combined with commas and leading
4103 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004104
4105- Implement PEP 378, Format Specifier for Thousands Separator, for
4106 floats.
4107
Mark Dickinson3370cce2009-04-17 22:40:53 +00004108- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004109 1e11, not 1e12. This avoids printing 13 significant digits in
4110 situations where only 12 of them are correct. Example problem
4111 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4112 long time.)
4113
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004114- Issue #1580: On most platforms, use a 'short' float repr: for a
4115 finite float x, repr(x) now outputs a string based on the shortest
4116 sequence of decimal digits that rounds to x. Previous behaviour was
4117 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004118 Another minor difference is that the new repr switches to
4119 exponential notation at 1e16 instead of the previous 1e17; this
4120 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004121
4122 There's a new sys attribute sys.float_repr_style, which takes
4123 the value 'short' to indicate that we're using short float repr,
4124 and 'legacy' if the short float repr isn't available for one
4125 reason or another.
4126
4127 The float repr change involves incorporating David Gay's 'perfect
4128 rounding' code into the Python core (it's in Python/dtoa.c). As a
4129 secondary consequence, all string-to-float and float-to-string
4130 conversions (including all float formatting operations) will be
4131 correctly rounded on these platforms.
4132
Georg Brandl5f90d792010-08-01 22:31:05 +00004133 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004134 this change does not apply.
4135
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004136- Issue #5759: float() didn't call __float__ on str subclasses.
4137
Georg Brandlabc38772009-04-12 15:51:51 +00004138- The string.maketrans() function is deprecated; there is a new static method
4139 maketrans() on the bytes and bytearray classes. This removes confusion about
4140 the types string.maketrans() is supposed to work with, and mirrors the
4141 methods available on the str class.
4142
R. David Murraydc6da8a2009-04-09 22:16:43 +00004143- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4144 its clarity and its speed.
4145
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004146- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004147 to avoid compiler warnings.
4148
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004149- Issue #3739: The unicode-internal encoder now reports the number of characters
4150 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrou57f3d932009-04-27 21:04:19 +00004207- Issue #5853: calling a function of the mimetypes module from several threads
4208 at once could hit the recursion limit if the mimetypes database hadn't been
4209 initialized before.
4210
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00004211- Issue #5854: Updated __all__ to include some missing names and remove some

4221 instances.
4222
Mark Dickinsoncf63f2f2009-04-22 17:50:21 +00004223- Issue #5812: Fraction('1e6') is valid: more generally, any string
4224 that's valid for float() is now valid for Fraction(), with the
4225 exception of strings representing NaNs and infinities.

R. David Murray9e94ddf2009-04-13 17:06:33 +00004230- Issue #1161031: fix readwrite select flag handling: POLLPRI now
4231 results in a handle_expt_event call, not handle_read_event, and POLLERR
4232 and POLLNVAL now call handle_close, not handle_expt_event. Also,
4233 dispatcher now has an 'ignore_log_types' attribute for suppressing
4234 log messages, which is set to 'warning' by default.
4235
Matthias Klosea3d29e82009-04-07 13:13:10 +00004236- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for

Benjamin Peterson8f76b492009-04-03 22:22:42 +00004287- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
4288
Benjamin Peterson7fe98532009-04-02 00:33:55 +00004289- Issue #5499: The 'c' code for argument parsing functions now only accepts a
4290 byte, and the 'C' code only accepts a unicode character.
4291
Georg Brandl406b3d82009-04-11 21:24:37 +00004292- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

4308
Antoine Pitrou3a652b12009-03-23 18:52:06 +00004309- Issue #4688: Add a heuristic so that tuples and dicts containing only
4310 untrackable objects are not tracked by the garbage collector. This can
4311 reduce the size of collections and therefore the garbage collection overhead
4312 on long-running programs, depending on their particular use of datatypes.

4319 2**15 for the internal representation of integers, for performance
4320 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
4321 --enable-big-digits option to configure, which overrides the
4322 default. Add sys.int_info structseq to provide information about
4323 the internal format.

4326 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
4327 and sizeof(Py_UNICODE) == 2.
4328
Eric Smith8ec90442009-03-14 12:29:34 +00004329- Issue #5237: Allow auto-numbered fields in str.format(). For

Antoine Pitrou652e7072009-03-13 19:25:20 +00004332- Issue #5392: when a very low recursion limit was set, the interpreter would
4333 abort with a fatal error after the recursion limit was hit twice.
4334
Matthias Klose042f1332009-04-04 14:32:42 +00004335- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

4383 forever on incomplete input. That caused tarfile.open() to hang when used
4384 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
4385 partial bzip2 compressed data.
4386

Vinay Sajip6268cbc2009-01-21 00:19:28 +00004497- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00004498 having been closed (for instance, a read() call could return some
4499 previously buffered data). Patch by Dmitry Vasiliev.
4500
Antoine Pitrou05608432009-01-09 18:53:14 +00004501- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
4502 flag to work properly. Furthermore, when specifying -u, the text stdout
4503 and stderr streams have line-by-line buffering enabled (the default being
4504 to buffer arbitrary chunks of data).
4505
Raymond Hettinger35631532009-01-09 03:58:09 +00004506- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
4507 instead of ints (reducing its size from 4 to 8 times thereby reducing
4508 Python's overall memory).
4509
Antoine Pitroud35cbf62009-01-06 19:02:24 +00004510- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
4511 an existing .py counterpart, override the co_filename attributes of all
4512 code objects if the original filename is obsolete (which can happen if the
4513 file has been renamed, moved, or if it is accessed through different paths).
4514 Patch by Ziga Seilnacht and Jean-Paul Calderone.
4515
Antoine Pitrouc3b39242009-01-03 16:59:18 +00004516- Issue #4580: Fix slicing of memoryviews when the item size is greater than
4517 one byte. Also fixes the meaning of len() so that it returns the number of
4518 items, rather than the size in bytes.
4519
Martin v. Löwis5c88d812009-01-02 20:47:48 +00004520- Issue #4075: Use OutputDebugStringW in Py_FatalError.
4521
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00004522- Issue #4747: When the terminal does not use utf-8, executing a script with
4523 non-ascii characters in its name could fail with a "SyntaxError: None" error.
4524
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004525- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
4526 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00004527
Antoine Pitrou7ddda782009-01-01 15:35:33 +00004528- Issue #3680: Reference cycles created through a dict, set or deque iterator
4529 did not get collected.
4530
Nick Coghlanf1f2f682008-12-30 07:29:12 +00004531- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
4532 where the tp_hash and tp_dict slots are both NULL.
4533
Georg Brandlccc47b62008-12-28 11:44:14 +00004534- Issue #4759: None is now allowed as the first argument of
4535 bytearray.translate(). It was always allowed for bytes.translate().
4536
Skip Montanaro80072cb2008-12-23 03:51:14 +00004537- Added test case to ensure attempts to read from a file opened for writing
4538 fail.
4539
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00004540- Issue #3106: Speedup some comparisons (str/str and int/int).
4541
Antoine Pitrouf289ae62008-12-18 11:06:25 +00004542- Issue #2183: Simplify and optimize bytecode for list, dict and set
4543 comprehensions. Original patch for list comprehensions by Neal Norwitz.
4544
Antoine Pitrou621601a2008-12-17 23:18:19 +00004545- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
4546 print elapsed times, not only when some objects are uncollectable /
4547 unreachable. Original patch by Neil Schemenauer.
4548
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00004549- Issue #3439: Add a bit_length method to int.
4550
Mark Dickinsonda2706b2008-12-11 18:03:03 +00004551- Issue #2173: When getting device encoding, check that return value of
4552 nl_langinfo is not the empty string. This was causing silent build
4553 failures on OS X.
4554
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00004555- Issue #4597: Fixed several opcodes that weren't always propagating
4556 exceptions.
4557
4558- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00004559 context manager returns a value that cannot be converted to a bool.
4560
Mark Dickinsonfd24b322008-12-06 15:33:31 +00004561- Issue #4445: Replace "sizeof(PyBytesObject)" with
4562 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
4563 bytes instances. On a typical machine this saves 3 bytes of memory
4564 (on average) per allocation of a bytes instance.
4565
Christian Heimesa872de52008-12-05 08:26:55 +00004566- Issue #4533: File read operation was dreadfully slow due to a slowly
4567 growing read buffer. Fixed by using the same growth rate algorithm as
4568 Python 2.x.
4569
Antoine Pitrou5504e892008-12-06 21:27:53 +00004570- Issue #4509: Various issues surrounding resize of bytearray objects to
4571 which there are buffer exports (e.g. memoryview instances).
4572
Georg Brandlf9734072008-12-07 15:30:06 +00004573- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
4574 method on file objects with closefd=False. The file descriptor is still
4575 kept open but the file object behaves like a closed file. The ``FileIO``
4576 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00004577
Antoine Pitroubc420402008-12-07 20:14:49 +00004578- Issue #4569: Interpreter crash when mutating a memoryview with an item size
4579 larger than 1.
4580

4584
Walter Dörwaldc1651a02009-05-03 22:55:55 +00004585- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
4586 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4587 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4588 of using the replace error handler in PyUnicode_DecodeUTF8().

4611 opening an empty or very small file.
4612

Antoine Pitrou08838b62009-01-21 00:55:13 +00004908- Issue #5008: When a file is opened in append mode with the new IO library,
4909 do an explicit seek to the end of file (so that e.g. tell() returns the

4941 appropriately when it is being used via socket.makefile() objects
4942 rather than delaying the close by waiting for garbage collection to do it.
