156 keyword-only argument. The preceding positional argument was deprecated,

185 encoding. This is the preferred encoding of PEP 3333 and the base encoding
186 of HTTP 1.1.
187
Armin Ronacher59531282011-01-22 13:44:22 +0000188- To match the behaviour of HTTP server, the HTTP client library now also
189 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
190 that for incoming headers which makes this behaviour now consistent in
191 both incoming and outgoing direction.

Georg Brandl255abdd2011-01-16 14:17:26 +0000282 continuation line in the formatted value has no leading white space and looks
283 like a header. Since Generator uses Header to format all headers, this check
284 is made for all headers in any serialized message at serialization time. This
285 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +0000286

Georg Brandl255abdd2011-01-16 14:17:26 +0000298 rfc2047-encoding header values with embedded newlines, leaving them without
299 folding whitespace. It now uses the continuation_ws, as it does for
300 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +0000302- Issue #1777412, #10827: Changed the rules for 2-digit years. The
303 time.asctime(), time.ctime() and time.strftime() functions will now format
304 any year when ``time.accept2dyear`` is False and will accept years >= 1000
305 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
306 supported by the OS. With Visual Studio or on Solaris, the year is limited to
307 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +0000931- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of

Victor Stinnerf933e1a2010-10-20 22:58:25 +0000933 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +0000934 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +0000935 encoding and to encode command line arguments on this OS.

Georg Brandl27a28582010-10-10 09:49:21 +00001327- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1328 with a non-empty format string. This is an effort to future-proof user
1329 code. If a derived class does not currently implement __format__ but later
1330 adds its own __format__, it would most likely break user code that had
1331 supplied a format string. This will be changed to a DeprecationWaring in
1332 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00001334- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1335 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1336 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
1337
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001338- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1339 functions from the libc caused the methods .upper() and lower() to become
1340 locale aware and created subtly wrong results.
1341
Georg Brandl27a28582010-10-10 09:49:21 +00001342- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1343 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001344
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001345- Issue #4617: Previously it was illegal to delete a name from the local
1346 namespace if it occurs as a free variable in a nested block. This limitation
1347 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1348
Georg Brandl27a28582010-10-10 09:49:21 +00001349- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1350 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1351 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1352 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00001353
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001354- Issue #9757: memoryview objects get a release() method to release the
1355 underlying buffer (previously this was only done when deallocating the
1356 memoryview), and gain support for the context management protocol.
1357
Antoine Pitrou079ce542010-09-08 12:37:10 +00001358- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1359 thread-local storage key.

Antoine Pitrou7980eaa2010-10-06 21:21:18 +00001381- Issue #9759: GzipFile now raises ValueError when an operation is attempted
1382 after the file is closed. Patch by Jeffrey Finkelstein.
1383
Éric Araujo6108bf52010-10-04 23:52:37 +00001384- Issue #9042: Fix interaction of custom translation classes and caching in

1386
Éric Araujoef777bd2010-10-05 00:04:20 +00001387- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001388 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001389 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001390 replacement for old handle_accept() and avoids the user to call accept()
1391 directly.

1409 conforms to the philosophy of bytes and unicode separation in Python 3. A
1410 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00001411
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00001412- Issue #9962: GzipFile now has the peek() method.
1413
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001414- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00001415 retry the select() loop instead of bailing out. This is because select() can
1416 incorrectly report a socket as ready for reading (for example, if it received
1417 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001418
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00001419- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

1453
Georg Brandl27a28582010-10-10 09:49:21 +00001454- logging: Changed LoggerAdapter implementation internally, to make it easier to
1455 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00001456
Vinay Sajipc84f0162010-09-21 11:25:39 +00001457- logging: hasHandlers method was added to Logger, and isEnabledFor,
1458 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
1459 LoggerAdapter was introduced into the unit tests for logging.
1460
Florent Xiclunaeb19dce2010-09-18 23:34:07 +00001461- Issue #1686: Fix string.Template when overriding the pattern attribute.
1462
Antoine Pitrou98b46702010-09-18 22:59:00 +00001463- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00001464 non-blocking mode: they return None when an operation would block (instead of
1465 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00001466
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00001467- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
1468 another kind.

Georg Brandl27a28582010-10-10 09:49:21 +00001474- Issue #9854: The default read() implementation in io.RawIOBase now handles
1475 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00001476
Georg Brandl27a28582010-10-10 09:49:21 +00001477- Issue #1552: socket.socketpair() now returns regular socket.socket objects
1478 supporting the whole socket API (rather than the "raw" _socket.socket
1479 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00001480
Georg Brandl27a28582010-10-10 09:49:21 +00001481- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
1482 to match the corresponding socket methods.

Georg Brandl27a28582010-10-10 09:49:21 +00001484- Issue 9840: Added a decorator to reprlib for wrapping __repr__ methods to make
1485 them handle recursive calls within the same thread.
Raymond Hettinger98a5f3f2010-09-13 21:36:00 +00001486

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00001491- Issue #9837: The read() method of ZipExtFile objects (as returned by
1492 ZipFile.open()) could return more bytes than requested.
1493
Georg Brandl27a28582010-10-10 09:49:21 +00001494- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:

Raymond Hettingerdc08a142010-09-12 05:15:22 +00001496
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001497- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001498 it possible for the user to create self-referencing ordered dictionaries which
1499 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001500 approach of using weakref proxies so that reference cycles never get created
1501 in the first place.
1502
Victor Stinnercb043522010-09-10 23:49:04 +00001503- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
1504 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00001505 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00001506
Georg Brandl27a28582010-10-10 09:49:21 +00001507- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
1508 environment variable to set the filesystem encoding at Python startup.
1509 sys.setfilesystemencoding() creates inconsistencies because it is unable to
1510 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00001511
Georg Brandl27a28582010-10-10 09:49:21 +00001512- Issue #9410: Various optimizations to the pickle module, leading to speedups
1513 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
1514 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00001515
Georg Brandl27a28582010-10-10 09:49:21 +00001516- The pprint module now supports printing OrderedDicts in their given order
1517 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00001518
Vinay Sajip121a1c42010-09-08 10:46:15 +00001519- Logging: Added QueueHandler class to facilitate logging usage with
1520 multiprocessing.
1521
Georg Brandl27a28582010-10-10 09:49:21 +00001522- Issue #9707: Rewritten reference implementation of threading.local which is
1523 friendlier towards reference cycles. This change is not normally visible
1524 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00001525
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001526- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1527 still return the id of the parent process after it has exited. This process
1528 id may even have been reused by another unrelated process.
1529
Georg Brandl27a28582010-10-10 09:49:21 +00001530- Issue #9792: In case of connection failure, socket.create_connection() would
1531 swallow the exception and raise a new one, making it impossible to fetch the
1532 original errno, or to filter timeout errors. Now the original error is
1533 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00001534
Georg Brandl27a28582010-10-10 09:49:21 +00001535- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
1536 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
1537 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00001538
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001539- Updates to the random module:
1540
Georg Brandl27a28582010-10-10 09:49:21 +00001541 * Document which parts of the module are guaranteed to stay the same across
1542 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001543
Georg Brandl27a28582010-10-10 09:49:21 +00001544 * Update the seed() method to use all of the bits in a string instead of just
1545 the hash value. This makes better use of the seed value and assures the
1546 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00001547
Georg Brandl27a28582010-10-10 09:49:21 +00001548 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1549 sample(), randrange(), and randint(). Formerly, it used int(n*random())
1550 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00001551
1552 * Improved documentation of arguments to randrange(). Issue #9379.
Raymond Hettingerf763a722010-09-07 00:38:15 +00001553
Georg Brandl27a28582010-10-10 09:49:21 +00001554- collections.OrderedDict now supports a new method for repositioning keys to
1555 either end.
Raymond Hettingerf45abc92010-09-06 21:26:09 +00001556
Georg Brandl27a28582010-10-10 09:49:21 +00001557- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
1558 cases now also have assertWarns and assertWarnsRegexp methods to check that a
1559 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00001560
Georg Brandl27a28582010-10-10 09:49:21 +00001561- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
1562 their contents without duplicating them. The view is both readable and
1563 writable.
Antoine Pitrou972ee132010-09-06 18:48:21 +00001564
Brian Curtin62857742010-09-06 17:07:27 +00001565- Issue #7566: Implement os.path.sameopenfile for Windows.
1566
Antoine Pitrou0d739d72010-09-05 23:01:12 +00001567- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00001568 unsupported operation is attempted (for example, writing to a file open only
1569 for reading).
Antoine Pitrou0d739d72010-09-05 23:01:12 +00001570

1703 return characters from the full Unicode range, even on narrow unicode builds
1704 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
1705 in Python is that unicodedata.numeric() now returns the correct value for
1706 large code points, and repr() may consider more characters as printable.

1741 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00001742
Georg Brandl649971e2010-09-05 17:06:50 +00001743- Issue #9416: Fix some issues with complex formatting where the output with no
1744 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00001745
1746 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
1747 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

2085
Ezio Melotti57221d02010-07-01 07:32:02 +00002086- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002087 start byte and the continuation byte(s) are now considered invalid, instead of
2088 the number of bytes specified by the start byte. E.g.:
2089 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2090 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2091 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2092 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00002094- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2095 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00002106- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
2107 dealing with unary minus applied to a constant. The removed code was mutating
2108 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00002109
Victor Stinner554f3f02010-06-16 23:33:54 +00002110- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002111 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002112 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002113 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002114
Victor Stinner25e8ec42010-06-25 00:02:38 +00002115- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
2116 "w*" format instead. Add tests for "w*" format.
2117
Victor Stinner06e49dd2010-06-13 18:21:50 +00002118- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002119 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002120 string formats.
2121
Georg Brandl62069d32010-07-31 08:56:11 +00002122- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002123 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2124 location of the raised exception.
2125
Victor Stinner313a1202010-06-11 23:56:51 +00002126- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2127 filenames and enable os.fsencode().
2128
Benjamin Peterson285a6892010-06-22 19:21:52 +00002129- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2130
Georg Brandl62069d32010-07-31 08:56:11 +00002131- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2132 interpreter with characters outside the Basic Multilingual Plane (higher than
2133 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002134
Georg Brandl62069d32010-07-31 08:56:11 +00002135- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2136 TypeError instead of giving a DeprecationWarning when a float is parsed using
2137 the 'L' code (for long long). (All other integer codes already raise
2138 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002139
Victor Stinner600d3be2010-06-10 12:00:55 +00002140- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2141 enable shortcuts for upper case encoding name. Add also a shortcut for
2142 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2143
Georg Brandl62069d32010-07-31 08:56:11 +00002144- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2145 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002146
2147- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002148 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002149 like bytearray.
2150
Georg Brandl62069d32010-07-31 08:56:11 +00002151- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002152 used anymore and it was never documented.
2153
Georg Brandl62069d32010-07-31 08:56:11 +00002154- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00002155
Georg Brandl62069d32010-07-31 08:56:11 +00002156- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
2157 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002158
Georg Brandl62069d32010-07-31 08:56:11 +00002159- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2160 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2161 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2162 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002163
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002164- Issue #8748: Fix two issues with comparisons between complex and integer
2165 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002166 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2167 (2) The comparison raised an OverflowError for large integers, leading to
2168 unpredictable exceptions when combining integers and complex objects in sets
2169 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002170
Victor Stinner7d79b8b2010-05-19 20:40:50 +00002171- Issue #8766: Initialize _warnings module before importing the first module.
2172 Fix a crash if an empty directory called "encodings" exists in sys.path.
2173
Victor Stinner9ca9c252010-05-19 16:53:30 +00002174- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002175 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002176 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002177
Georg Brandl62069d32010-07-31 08:56:11 +00002178- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2179 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002180
Victor Stinnerae6265f2010-05-15 16:27:27 +00002181- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2182 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002183 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002184 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002185
Victor Stinner59e62db2010-05-15 13:14:32 +00002186- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002187 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002188
Victor Stinnerb744ba12010-05-15 12:27:16 +00002189- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002190 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002191 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2192
Victor Stinner0964ee12010-04-30 16:48:45 +00002193- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002194 PyUnicode_FromString() to support surrogates in the filename and use the right
2195 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00002196
Georg Brandl8569e582010-05-19 20:57:08 +00002197- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
2198
Georg Brandl62069d32010-07-31 08:56:11 +00002199- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00002200
Benjamin Petersonfb886362010-04-24 18:21:17 +00002201- Issue #8419: Prevent the dict constructor from accepting non-string keyword
2202 arguments.
2203
Victor Stinner14284c22010-04-23 12:02:30 +00002204- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00002205 indirectly Python signal handlers anymore because mywrite() ignores exceptions
2206 (KeyboardInterrupt).

Georg Brandl62069d32010-07-31 08:56:11 +00002211- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
2212 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00002213
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00002214- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00002215 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

2295 crash in many places because of the PyByteArray_AS_STRING() macro returning
2296 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00002298- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00002299 where the right hand operand is a set of constants, by turning the set into a
2300 frozenset and pre-building it as a constant. The comparison operation is made
2301 against the constant instead of building a new set each time it is executed (a
2302 similar optimization already existed which turned a list of constants into a
2303 pre-built tuple). Patch and additional tests by Dave Malcolm.

2310 including: (1) a serious 'wrong output' bug that could occur for long (> 40
2311 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
2312 parsing certain long numeric strings corresponding to subnormal values, (3) a
2313 memory leak for some values large enough to cause overflow, and (4) a number
2314 of flaws that could lead to incorrectly rounded results.

2329 of integers: the result of a/b is now correctly rounded for ints a and b (at
2330 least on IEEE 754 platforms), and in particular does not depend on the
2331 internal representation of an int.

2356
Georg Brandl62069d32010-07-31 08:56:11 +00002357- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
2358 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
2359 long but the length of the range did not. Also fix several cases where
2360 reversed(range(a, b, c)) gave wrong results, and fix a refleak for

Georg Brandl62069d32010-07-31 08:56:11 +00002604- The default size of the re module's compiled regular expression cache has been
2605 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00002606 simply clearing the entire cache on overflow to forgetting the least recently
2607 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00002608 applications that use a lot of regular expressions and limits the impact of
2609 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00002621- Issue #7989: Added pure python implementation of the `datetime` module. The C
2622 module is renamed to `_datetime` and if available, overrides all classes
2623 defined in datetime with fast C impementation. Python implementation is based
2624 on the original python prototype for the datetime module by Tim Peters with
2625 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00002981- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00002982 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00002983 relies on the system threading library, so as to avoid a semi-busy wait loop.

R. David Murrayb2416e52010-04-12 16:58:02 +00002989- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00002990 filename and date, conforming to the 'standards' they were originally designed

Raymond Hettingerc50846a2010-04-05 18:56:31 +00003007- Add functools.total_ordering() and functools.cmp_to_key().
3008
Georg Brandl62069d32010-07-31 08:56:11 +00003009- Issue #8257: The Decimal construct now accepts a float instance directly,
3010 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003011
3012 >>> Decimal(1.1)
3013 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00003018- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3019 InvalidOperation instead of returning False. (Comparisons involving a quiet
3020 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3021 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003022
Georg Brandl62069d32010-07-31 08:56:11 +00003023- Issue #2531: Comparison operations between floats and Decimal instances now
3024 return a result based on the numeric values of the operands; previously they
3025 returned an arbitrary result based on the relative ordering of id(float) and
3026 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3027 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003028
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003029- Added a subtract() method to collections.Counter().
3030
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003031- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003032 argument `-` which tells it to read files to compile from stdin. Each line is
3033 read on demand and the named file is compiled immediately. (Original patch by
3034 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003036- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3037 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00003038 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00003040- Comparisons using one of <, <=, >, >= between a complex instance and a
3041 Fractions instance now raise TypeError instead of returning True/False. This
3042 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3043 <=> complex, and complex <=> complex comparisons.

3051
Antoine Pitrou910bd512010-03-22 20:11:09 +00003052- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00003053 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00003086- The internals of the subprocess module on POSIX systems have been replaced by
3087 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3088 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003089
Georg Brandl62069d32010-07-31 08:56:11 +00003090- subprocess.Popen now has restore_signals and start_new_session features. The
3091 default of restore_signals=True is a new behavior compared to earlier Python
3092 versions. This means that signals such as SIGPIPE are not ignored by default
3093 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00003179- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
3180 position when calling `truncate()`. It would previously change the file
3181 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00003182 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3183
Antoine Pitroua32f9a22010-01-27 21:18:57 +00003184- Issue #7610: Reworked implementation of the internal

3186 archive. The new implementation is significantly faster and can be wrapped in
3187 a :class:`io.BufferedReader` object for more speedups. It also solves an
3188 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00003586- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00003587 compared to other unix systems. In particular, os.getgroups() does not reflect
3588 any changes made using os.setgroups() but basicly always returns the same
3589 information as the id command. os.getgroups() can now return more than 16
3590 groups on MacOSX.

Antoine Pitroue4501852009-05-14 18:55:55 +00004182- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4183 library. This means, for example, that opening an UTF-16 text file in
4184 append mode doesn't add a BOM at the end of the file if the file isn't
4185 empty.

4235Core and Builtins
4236-----------------
4237
Mark Dickinson865e01a2009-05-07 16:37:01 +00004238- Issue #5914: Add new C API function PyOS_string_to_double, and
4239 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4240
Eric Smith741191f2009-05-06 13:08:15 +00004241- Issue #3382: float.__format__, complex.__format__, and %-formatting
4242 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4243 affects nan -> NAN and inf -> INF.
4244
Mark Hammond5a607a32009-05-06 08:04:54 +00004245- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4246 in all operations, including splitdrive, split, etc. splitunc() now issues
4247 a PendingDeprecation warning.
4248
Eric Smith63376222009-05-05 14:04:18 +00004249- Issue #5920: For float.__format__, change the behavior with the
4250 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4251 to be like 'g' but with at least one decimal point and with a
4252 default precision of 12. Previously, the behavior the same but with
4253 a default precision of 6. This more closely matches str(), and
4254 reduces surprises when adding alignment flags to the empty
4255 presentation type. This also affects the new complex.__format__ in
4256 the same way.
4257
Martin v. Löwis011e8422009-05-05 04:43:17 +00004258- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4259
R. David Murrayb18500d2009-05-04 22:59:07 +00004260- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4261 shadowed by classtype's, even if it was None. property now
4262 inserts the __doc__ into the subclass instance __dict__.
4263
Antoine Pitrou244651a2009-05-04 18:56:13 +00004264- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4265 sequences. Patch by Nick Barnes and Victor Stinner.
4266
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004267- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004268
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004269- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4270 received a new method, detach(). detach() disconnects the underlying stream
4271 from the buffer or text IO and returns it.
4272
Mark Dickinson33841c32009-05-01 15:37:04 +00004273- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4274 floats with absolute value over 1e50. Also remove length
4275 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4276 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004277
Eric Smith741191f2009-05-06 13:08:15 +00004278- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004279 format(complex(1, 2./3), '.5') now produces a sensible result.
4280
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004281- Issue #5864: Fix empty format code formatting for floats so that it
4282 never gives more than the requested number of significant digits.
4283
Eric Smith6dc46f52009-04-27 20:39:49 +00004284- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4285 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4286
Eric Smithcc32a112009-04-26 21:35:14 +00004287- Issue #5835: Deprecate PyOS_ascii_formatd.
4288
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004289- Issue #4971: Fix titlecase for characters that are their own
4290 titlecase, but not their own uppercase.
4291
Benjamin Peterson193152c2009-04-25 01:08:45 +00004292- Issue #5283: Setting __class__ in __del__ caused a segfault.
4293
Mark Dickinsonad476da2009-04-23 19:14:16 +00004294- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4295 z involves nans, infs or negative zeros.
4296
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004297- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004298
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004299- Issue #1869 (and many duplicates): make round(x, n) correctly
4300 rounded for a float x, by using the decimal <-> binary conversions
4301 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4302 consistently agrees with format(x, '.2f').
4303
Benjamin Petersonae937c02009-04-18 20:54:08 +00004304- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4305 some builtin types.
4306
Eric Smith0923d1d2009-04-16 20:16:10 +00004307- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4308
Eric Smith35e84722009-04-16 20:21:28 +00004309- Issue #5515: str.format() type 'n' combined with commas and leading
4310 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004311
4312- Implement PEP 378, Format Specifier for Thousands Separator, for
4313 floats.
4314
Mark Dickinson3370cce2009-04-17 22:40:53 +00004315- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004316 1e11, not 1e12. This avoids printing 13 significant digits in
4317 situations where only 12 of them are correct. Example problem
4318 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4319 long time.)
4320
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004321- Issue #1580: On most platforms, use a 'short' float repr: for a
4322 finite float x, repr(x) now outputs a string based on the shortest
4323 sequence of decimal digits that rounds to x. Previous behaviour was
4324 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004325 Another minor difference is that the new repr switches to
4326 exponential notation at 1e16 instead of the previous 1e17; this
4327 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004328
4329 There's a new sys attribute sys.float_repr_style, which takes
4330 the value 'short' to indicate that we're using short float repr,
4331 and 'legacy' if the short float repr isn't available for one
4332 reason or another.
4333
4334 The float repr change involves incorporating David Gay's 'perfect
4335 rounding' code into the Python core (it's in Python/dtoa.c). As a
4336 secondary consequence, all string-to-float and float-to-string
4337 conversions (including all float formatting operations) will be
4338 correctly rounded on these platforms.
4339
Georg Brandl5f90d792010-08-01 22:31:05 +00004340 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004341 this change does not apply.
4342
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004343- Issue #5759: float() didn't call __float__ on str subclasses.
4344
Georg Brandlabc38772009-04-12 15:51:51 +00004345- The string.maketrans() function is deprecated; there is a new static method
4346 maketrans() on the bytes and bytearray classes. This removes confusion about
4347 the types string.maketrans() is supposed to work with, and mirrors the
4348 methods available on the str class.
4349
R. David Murraydc6da8a2009-04-09 22:16:43 +00004350- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4351 its clarity and its speed.
4352
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004353- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004354 to avoid compiler warnings.
4355
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004356- Issue #3739: The unicode-internal encoder now reports the number of characters
4357 consumed like any other encoder (instead of the number of bytes).

4500 when hitting the recursion limit under certain circumstances.
4501
Brett Cannon0759dd62009-04-01 18:13:07 +00004502- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
4503
Georg Brandlab6f2f62009-03-31 04:16:10 +00004504- Fix a segfault when running test_exceptions with coverage, caused by
4505 insufficient checks in accessors of Exception.__context__.
4506
Guido van Rossum0ad59d42009-03-30 22:01:35 +00004507- Issue #5604: non-ASCII characters in module name passed to
4508 imp.find_module() were converted to UTF-8 while the path is
4509 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00004511- Issue #5126: str.isprintable() returned False for space characters.
4512
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00004513- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
4514 the end sys.path, for compatibility with the system install of Python.
4515
Antoine Pitrou3a652b12009-03-23 18:52:06 +00004516- Issue #4688: Add a heuristic so that tuples and dicts containing only
4517 untrackable objects are not tracked by the garbage collector. This can
4518 reduce the size of collections and therefore the garbage collection overhead
4519 on long-running programs, depending on their particular use of datatypes.
4520
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00004521- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

4533 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
4534 and sizeof(Py_UNICODE) == 2.
4535
Eric Smith8ec90442009-03-14 12:29:34 +00004536- Issue #5237: Allow auto-numbered fields in str.format(). For

4538
Antoine Pitrou652e7072009-03-13 19:25:20 +00004539- Issue #5392: when a very low recursion limit was set, the interpreter would
4540 abort with a fatal error after the recursion limit was hit twice.
4541
Matthias Klose042f1332009-04-04 14:32:42 +00004542- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

4588
Lars Gustäbel42e00912009-03-22 20:34:29 +00004589- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
4590 forever on incomplete input. That caused tarfile.open() to hang when used
4591 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
4592 partial bzip2 compressed data.
4593
Mark Dickinson79f52032009-03-17 23:12:51 +00004594- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonae681df2009-03-21 10:26:31 +00004611- Issue #5463: In struct module, remove deprecated overflow wrapping
4612 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00004613 struct.error instead of returning b'\xff\xff\xff\xff'. The
4614 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

Mark Dickinson87ec0852009-02-09 17:15:59 +00004642- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
4643 it now forces its argument to double before testing for infinity.
4644
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00004645- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
4646 returns a non-number type.
4647
Benjamin Peterson87618552009-02-08 15:00:52 +00004648- Issue #5182: Removed memoryview.__str__.

Raymond Hettingere8364232009-02-02 22:55:09 +00004656 were suppressing all exceptions. These include list() and bytearray().
4657
Mark Dickinson1124e712009-01-28 21:25:58 +00004658- Issue #4707: round(x, n) now returns an integer if x is an integer.
4659 Previously it returned a float.
4660

4662 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
4663 evaluation loop is compiled with a new dispatch mechanism which gives
4664 speedups of up to 20%, depending on the system, on various benchmarks.

Georg Brandl65ce6ad2010-09-05 17:32:31 +00004677 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00004678
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00004679- Issue #4935: The overflow checking code in the expandtabs() method common
4680 to str, bytes and bytearray could be optimized away by the compiler, letting
4681 the interpreter segfault instead of raising an error.
4682
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00004683- Issue #3720: Fix a crash when an iterator modifies its class and removes its

4695 common cases are optimized thanks to a dedicated fast path and a moderate
4696 amount of loop unrolling.
4697
Antoine Pitrou14b78f52009-01-09 22:27:08 +00004698- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
4699 collecting the oldest generation) so that allocating lots of objects without
4700 destroying them does not show quadratic performance. Based on a proposal by

Antoine Pitrou8043cf82009-01-09 19:54:29 +00004705 having been closed (for instance, a read() call could return some
4706 previously buffered data). Patch by Dmitry Vasiliev.
4707
Antoine Pitrou05608432009-01-09 18:53:14 +00004708- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
4709 flag to work properly. Furthermore, when specifying -u, the text stdout
4710 and stderr streams have line-by-line buffering enabled (the default being
4711 to buffer arbitrary chunks of data).
4712
Raymond Hettinger35631532009-01-09 03:58:09 +00004713- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
4714 instead of ints (reducing its size from 4 to 8 times thereby reducing
4715 Python's overall memory).
4716
Antoine Pitroud35cbf62009-01-06 19:02:24 +00004717- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
4718 an existing .py counterpart, override the co_filename attributes of all
4719 code objects if the original filename is obsolete (which can happen if the
4720 file has been renamed, moved, or if it is accessed through different paths).
4721 Patch by Ziga Seilnacht and Jean-Paul Calderone.
4722
Antoine Pitrouc3b39242009-01-03 16:59:18 +00004723- Issue #4580: Fix slicing of memoryviews when the item size is greater than
4724 one byte. Also fixes the meaning of len() so that it returns the number of
4725 items, rather than the size in bytes.
4726
Martin v. Löwis5c88d812009-01-02 20:47:48 +00004727- Issue #4075: Use OutputDebugStringW in Py_FatalError.
4728
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00004729- Issue #4747: When the terminal does not use utf-8, executing a script with

4737
Nick Coghlanf1f2f682008-12-30 07:29:12 +00004738- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
4739 where the tp_hash and tp_dict slots are both NULL.
4740
Georg Brandlccc47b62008-12-28 11:44:14 +00004741- Issue #4759: None is now allowed as the first argument of
4742 bytearray.translate(). It was always allowed for bytes.translate().
4743
Skip Montanaro80072cb2008-12-23 03:51:14 +00004744- Added test case to ensure attempts to read from a file opened for writing
4745 fail.

5114
Antoine Pitrou08838b62009-01-21 00:55:13 +00005115- Issue #5008: When a file is opened in append mode with the new IO library,
5116 do an explicit seek to the end of file (so that e.g. tell() returns the
5117 file size rather than 0). This is consistent with the behaviour of the

5148 appropriately when it is being used via socket.makefile() objects
5149 rather than delaying the close by waiting for garbage collection to do it.
5150
Raymond Hettingerb8baf632009-01-14 02:20:07 +00005151- Issue #1696199: Add collections.Counter() for rapid and convenient
