641 files in binary mode, using the email package's binary support to parse

672 keyword-only argument. The preceding positional argument was deprecated,
673 so it made no sense to add filter as a positional argument.

701 encoding. This is the preferred encoding of PEP 3333 and the base encoding
702 of HTTP 1.1.
703
Armin Ronacher59531282011-01-22 13:44:22 +0000704- To match the behaviour of HTTP server, the HTTP client library now also
705 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
706 that for incoming headers which makes this behaviour now consistent in
707 both incoming and outgoing direction.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001462- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1463 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001464 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001465 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001466 encoding and to encode command line arguments on this OS.

Benjamin Peterson230b2062010-10-16 03:45:45 +00001472- Issue #9997: Don't let the name "top" have special significance in scope

1859 with a non-empty format string. This is an effort to future-proof user
1860 code. If a derived class does not currently implement __format__ but later
1861 adds its own __format__, it would most likely break user code that had
1862 supplied a format string. This will be changed to a DeprecationWaring in

Antoine Pitrou1df15362010-09-13 14:16:46 +00001865- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1866 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1867 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 +00001869- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1870 functions from the libc caused the methods .upper() and lower() to become
1871 locale aware and created subtly wrong results.
1872
Georg Brandl27a28582010-10-10 09:49:21 +00001873- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001876- Issue #4617: Previously it was illegal to delete a name from the local
1877 namespace if it occurs as a free variable in a nested block. This limitation
1878 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1879
Georg Brandl27a28582010-10-10 09:49:21 +00001880- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1881 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1882 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1883 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001885- Issue #9757: memoryview objects get a release() method to release the
1886 underlying buffer (previously this was only done when deallocating the
1887 memoryview), and gain support for the context management protocol.
1888
Antoine Pitrou079ce542010-09-08 12:37:10 +00001889- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00001918- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001919 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001920 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001921 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00001946 retry the select() loop instead of bailing out. This is because select() can
1947 incorrectly report a socket as ready for reading (for example, if it received
1948 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00001995 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002028- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002029 it possible for the user to create self-referencing ordered dictionaries which
2030 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002031 approach of using weakref proxies so that reference cycles never get created
2032 in the first place.
2033
Victor Stinnercb043522010-09-10 23:49:04 +00002034- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2035 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002036 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002037
Georg Brandl27a28582010-10-10 09:49:21 +00002038- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2039 environment variable to set the filesystem encoding at Python startup.
2040 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2041 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002043- Issue #9410: Various optimizations to the pickle module, leading to speedups

Georg Brandl27a28582010-10-10 09:49:21 +00002047- The pprint module now supports printing OrderedDicts in their given order

Vinay Sajip121a1c42010-09-08 10:46:15 +00002050- Logging: Added QueueHandler class to facilitate logging usage with
2051 multiprocessing.
2052
Georg Brandl27a28582010-10-10 09:49:21 +00002053- Issue #9707: Rewritten reference implementation of threading.local which is
2054 friendlier towards reference cycles. This change is not normally visible
2055 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002056
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002057- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2058 still return the id of the parent process after it has exited. This process
2059 id may even have been reused by another unrelated process.
2060
Georg Brandl27a28582010-10-10 09:49:21 +00002061- Issue #9792: In case of connection failure, socket.create_connection() would
2062 swallow the exception and raise a new one, making it impossible to fetch the
2063 original errno, or to filter timeout errors. Now the original error is
2064 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00002065
Georg Brandl27a28582010-10-10 09:49:21 +00002066- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2067 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2068 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002070- Updates to the random module:
2071
Georg Brandl27a28582010-10-10 09:49:21 +00002072 * Document which parts of the module are guaranteed to stay the same across
2073 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002074
Georg Brandl27a28582010-10-10 09:49:21 +00002075 * Update the seed() method to use all of the bits in a string instead of just
2076 the hash value. This makes better use of the seed value and assures the
2077 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002078
Georg Brandl27a28582010-10-10 09:49:21 +00002079 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2080 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2081 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002082
2083 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002088- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2089 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2090 given warning type was triggered by the code under test.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002098- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002099 unsupported operation is attempted (for example, writing to a file open only
2100 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002102- hashlib has two new constant attributes: algorithms_guaranteed and
2103 algorithms_avaiable that respectively list the names of hash algorithms
2104 guaranteed to exist in all Python implementations and the names of hash
2105 algorithms available in the current process.
2106
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002107- A new package ``concurrent.futures`` as defined by PEP 3148.

2235 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

Georg Brandl649971e2010-09-05 17:06:50 +00002274- Issue #9416: Fix some issues with complex formatting where the output with no
2275 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002276
2277 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2278 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Victor Stinner8182b712010-07-28 00:40:58 +00002610- Issue #8991: convertbuffer() rejects discontigious buffers.
2611
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00002612- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
2613 compiler.
2614
Benjamin Petersonccabcd42010-07-07 20:54:01 +00002615- Issue #8413: structsequence now subclasses tuple.
2616
Ezio Melotti57221d02010-07-01 07:32:02 +00002617- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002618 start byte and the continuation byte(s) are now considered invalid, instead of
2619 the number of bytes specified by the start byte. E.g.:
2620 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2621 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2622 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2623 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00002624
Georg Brandl62069d32010-07-31 08:56:11 +00002625- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2626 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00002627
Benjamin Peterson88968ad2010-06-25 19:30:21 +00002628- Be more specific in error messages about positional arguments.
2629
Victor Stinner4aae1eb2010-06-24 22:08:25 +00002630- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
2631 objects, as described in the documentation.
2632
Victor Stinner0fe25a42010-06-17 23:08:50 +00002633- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.

Georg Brandl62069d32010-07-31 08:56:11 +00002637- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
2638 dealing with unary minus applied to a constant. The removed code was mutating
2639 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00002640
Victor Stinner554f3f02010-06-16 23:33:54 +00002641- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002642 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002643 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002644 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002645
Victor Stinner25e8ec42010-06-25 00:02:38 +00002646- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
2647 "w*" format instead. Add tests for "w*" format.
2648
Victor Stinner06e49dd2010-06-13 18:21:50 +00002649- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002650 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002651 string formats.
2652
Georg Brandl62069d32010-07-31 08:56:11 +00002653- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002654 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2655 location of the raised exception.
2656
Victor Stinner313a1202010-06-11 23:56:51 +00002657- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2658 filenames and enable os.fsencode().
2659
Benjamin Peterson285a6892010-06-22 19:21:52 +00002660- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2661
Georg Brandl62069d32010-07-31 08:56:11 +00002662- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2663 interpreter with characters outside the Basic Multilingual Plane (higher than
2664 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002665
Georg Brandl62069d32010-07-31 08:56:11 +00002666- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2667 TypeError instead of giving a DeprecationWarning when a float is parsed using
2668 the 'L' code (for long long). (All other integer codes already raise
2669 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002670
Victor Stinner600d3be2010-06-10 12:00:55 +00002671- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2672 enable shortcuts for upper case encoding name. Add also a shortcut for
2673 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2674
Georg Brandl62069d32010-07-31 08:56:11 +00002675- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2676 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002677
2678- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002679 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002680 like bytearray.
2681
Georg Brandl62069d32010-07-31 08:56:11 +00002682- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002683 used anymore and it was never documented.
2684
Georg Brandl62069d32010-07-31 08:56:11 +00002685- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00002686
Georg Brandl62069d32010-07-31 08:56:11 +00002687- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
2688 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002689
Georg Brandl62069d32010-07-31 08:56:11 +00002690- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2691 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2692 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2693 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002694
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002695- Issue #8748: Fix two issues with comparisons between complex and integer
2696 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002697 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2698 (2) The comparison raised an OverflowError for large integers, leading to
2699 unpredictable exceptions when combining integers and complex objects in sets
2700 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002701
Victor Stinner7d79b8b2010-05-19 20:40:50 +00002702- Issue #8766: Initialize _warnings module before importing the first module.
2703 Fix a crash if an empty directory called "encodings" exists in sys.path.
2704
Victor Stinner9ca9c252010-05-19 16:53:30 +00002705- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002706 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002707 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002708
Georg Brandl62069d32010-07-31 08:56:11 +00002709- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2710 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002711
Victor Stinnerae6265f2010-05-15 16:27:27 +00002712- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2713 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002714 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002715 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002716
Victor Stinner59e62db2010-05-15 13:14:32 +00002717- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002718 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002719
Victor Stinnerb744ba12010-05-15 12:27:16 +00002720- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002721 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002722 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2723
Victor Stinner0964ee12010-04-30 16:48:45 +00002724- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002725 PyUnicode_FromString() to support surrogates in the filename and use the right
2726 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00002727
Georg Brandl8569e582010-05-19 20:57:08 +00002728- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
2729
Georg Brandl62069d32010-07-31 08:56:11 +00002730- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00002731
Benjamin Petersonfb886362010-04-24 18:21:17 +00002732- Issue #8419: Prevent the dict constructor from accepting non-string keyword
2733 arguments.
2734
Victor Stinner14284c22010-04-23 12:02:30 +00002735- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00002736 indirectly Python signal handlers anymore because mywrite() ignores exceptions
2737 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00002738
Victor Stinner31be90b2010-04-22 19:38:16 +00002739- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
Georg Brandl62069d32010-07-31 08:56:11 +00002740 unicode string (eg. backslashreplace).
Victor Stinner31be90b2010-04-22 19:38:16 +00002741
Georg Brandl62069d32010-07-31 08:56:11 +00002742- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
2743 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00002744
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00002745- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00002746 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
2747 compared to the dynamic memory allocation fallback. Patch by Charles-François
2748 Natali.

2826 crash in many places because of the PyByteArray_AS_STRING() macro returning
2827 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00002829- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00002830 where the right hand operand is a set of constants, by turning the set into a
2831 frozenset and pre-building it as a constant. The comparison operation is made
2832 against the constant instead of building a new set each time it is executed (a
2833 similar optimization already existed which turned a list of constants into a
2834 pre-built tuple). Patch and additional tests by Dave Malcolm.

2860 of integers: the result of a/b is now correctly rounded for ints a and b (at
2861 least on IEEE 754 platforms), and in particular does not depend on the
2862 internal representation of an int.

Georg Brandl62069d32010-07-31 08:56:11 +00003139 applications that use a lot of regular expressions and limits the impact of
3140 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003549- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3550 InvalidOperation instead of returning False. (Comparisons involving a quiet
3551 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3552 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003554- Issue #2531: Comparison operations between floats and Decimal instances now
3555 return a result based on the numeric values of the operands; previously they
3556 returned an arbitrary result based on the relative ordering of id(float) and
3557 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3558 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003562- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003563 argument `-` which tells it to read files to compile from stdin. Each line is
3564 read on demand and the named file is compiled immediately. (Original patch by
3565 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003567- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00003571- Comparisons using one of <, <=, >, >= between a complex instance and a
3572 Fractions instance now raise TypeError instead of returning True/False. This
3573 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3574 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003617- The internals of the subprocess module on POSIX systems have been replaced by
3618 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3619 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003620
Georg Brandl62069d32010-07-31 08:56:11 +00003621- subprocess.Popen now has restore_signals and start_new_session features. The
3622 default of restore_signals=True is a new behavior compared to earlier Python
3623 versions. This means that signals such as SIGPIPE are not ignored by default
3624 in subprocesses launched by Python (Issue #1652).

3711 position when calling `truncate()`. It would previously change the file
3712 position to the given argument, which goes against the tradition of

3717 archive. The new implementation is significantly faster and can be wrapped in
3718 a :class:`io.BufferedReader` object for more speedups. It also solves an
3719 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00004055- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004056 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4057 PyPycLoader inherit from this class and provide implementations in relation to
4058 other methods required by the ABCs.

Brett Cannon64ef00f2009-07-20 03:19:18 +00004060- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4061 the documentation said it did even though the code in PyLoader relied on the
4062 abstract method required by ResourceLoader.
4063
Georg Brandl62069d32010-07-31 08:56:11 +00004064- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004117- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004118 compared to other unix systems. In particular, os.getgroups() does not reflect
4119 any changes made using os.setgroups() but basicly always returns the same
4120 information as the id command. os.getgroups() can now return more than 16
4121 groups on MacOSX.

4719 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4720 corrects a pydoc regression.
4721
Georg Brandl5f90d792010-08-01 22:31:05 +00004722- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004723 now it does. This also means getfp method now returns the real fp.

4763
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00004764*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00004765
4766Core and Builtins
4767-----------------
4768
Mark Dickinson865e01a2009-05-07 16:37:01 +00004769- Issue #5914: Add new C API function PyOS_string_to_double, and
4770 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4771
Eric Smith741191f2009-05-06 13:08:15 +00004772- Issue #3382: float.__format__, complex.__format__, and %-formatting
4773 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4774 affects nan -> NAN and inf -> INF.
4775
Mark Hammond5a607a32009-05-06 08:04:54 +00004776- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4777 in all operations, including splitdrive, split, etc. splitunc() now issues
4778 a PendingDeprecation warning.
4779
Eric Smith63376222009-05-05 14:04:18 +00004780- Issue #5920: For float.__format__, change the behavior with the
4781 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4782 to be like 'g' but with at least one decimal point and with a
4783 default precision of 12. Previously, the behavior the same but with
4784 a default precision of 6. This more closely matches str(), and
4785 reduces surprises when adding alignment flags to the empty
4786 presentation type. This also affects the new complex.__format__ in
4787 the same way.
4788
Martin v. Löwis011e8422009-05-05 04:43:17 +00004789- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4790
R. David Murrayb18500d2009-05-04 22:59:07 +00004791- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4792 shadowed by classtype's, even if it was None. property now
4793 inserts the __doc__ into the subclass instance __dict__.
4794
Antoine Pitrou244651a2009-05-04 18:56:13 +00004795- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4796 sequences. Patch by Nick Barnes and Victor Stinner.
4797
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004798- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004799
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004800- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4801 received a new method, detach(). detach() disconnects the underlying stream
4802 from the buffer or text IO and returns it.
4803
Mark Dickinson33841c32009-05-01 15:37:04 +00004804- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4805 floats with absolute value over 1e50. Also remove length
4806 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4807 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004808
Eric Smith741191f2009-05-06 13:08:15 +00004809- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004810 format(complex(1, 2./3), '.5') now produces a sensible result.
4811
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004812- Issue #5864: Fix empty format code formatting for floats so that it
4813 never gives more than the requested number of significant digits.
4814
Eric Smith6dc46f52009-04-27 20:39:49 +00004815- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4816 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4817
Eric Smithcc32a112009-04-26 21:35:14 +00004818- Issue #5835: Deprecate PyOS_ascii_formatd.
4819
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004820- Issue #4971: Fix titlecase for characters that are their own
4821 titlecase, but not their own uppercase.
4822
Benjamin Peterson193152c2009-04-25 01:08:45 +00004823- Issue #5283: Setting __class__ in __del__ caused a segfault.
4824
Mark Dickinsonad476da2009-04-23 19:14:16 +00004825- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4826 z involves nans, infs or negative zeros.
4827
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004828- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004829
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004830- Issue #1869 (and many duplicates): make round(x, n) correctly
4831 rounded for a float x, by using the decimal <-> binary conversions
4832 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4833 consistently agrees with format(x, '.2f').
4834
Benjamin Petersonae937c02009-04-18 20:54:08 +00004835- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4836 some builtin types.
4837
Eric Smith0923d1d2009-04-16 20:16:10 +00004838- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4839
Eric Smith35e84722009-04-16 20:21:28 +00004840- Issue #5515: str.format() type 'n' combined with commas and leading
4841 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004842
4843- Implement PEP 378, Format Specifier for Thousands Separator, for
4844 floats.
4845
Mark Dickinson3370cce2009-04-17 22:40:53 +00004846- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004847 1e11, not 1e12. This avoids printing 13 significant digits in
4848 situations where only 12 of them are correct. Example problem
4849 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4850 long time.)
4851
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004852- Issue #1580: On most platforms, use a 'short' float repr: for a
4853 finite float x, repr(x) now outputs a string based on the shortest
4854 sequence of decimal digits that rounds to x. Previous behaviour was
4855 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004856 Another minor difference is that the new repr switches to
4857 exponential notation at 1e16 instead of the previous 1e17; this
4858 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004859
4860 There's a new sys attribute sys.float_repr_style, which takes
4861 the value 'short' to indicate that we're using short float repr,
4862 and 'legacy' if the short float repr isn't available for one
4863 reason or another.
4864
4865 The float repr change involves incorporating David Gay's 'perfect
4866 rounding' code into the Python core (it's in Python/dtoa.c). As a
4867 secondary consequence, all string-to-float and float-to-string
4868 conversions (including all float formatting operations) will be
4869 correctly rounded on these platforms.
4870
Georg Brandl5f90d792010-08-01 22:31:05 +00004871 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004872 this change does not apply.
4873
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004874- Issue #5759: float() didn't call __float__ on str subclasses.
4875
Georg Brandlabc38772009-04-12 15:51:51 +00004876- The string.maketrans() function is deprecated; there is a new static method
4877 maketrans() on the bytes and bytearray classes. This removes confusion about
4878 the types string.maketrans() is supposed to work with, and mirrors the
4879 methods available on the str class.
4880
R. David Murraydc6da8a2009-04-09 22:16:43 +00004881- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4882 its clarity and its speed.
4883
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004884- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004885 to avoid compiler warnings.
4886
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004887- Issue #3739: The unicode-internal encoder now reports the number of characters
4888 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00005025- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
5026
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005027- Issue #5499: The 'c' code for argument parsing functions now only accepts a
5028 byte, and the 'C' code only accepts a unicode character.
5029
Georg Brandl406b3d82009-04-11 21:24:37 +00005030- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
5031 when hitting the recursion limit under certain circumstances.
5032
Brett Cannon0759dd62009-04-01 18:13:07 +00005033- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
5034
Georg Brandlab6f2f62009-03-31 04:16:10 +00005035- Fix a segfault when running test_exceptions with coverage, caused by
5036 insufficient checks in accessors of Exception.__context__.
5037
Guido van Rossum0ad59d42009-03-30 22:01:35 +00005038- Issue #5604: non-ASCII characters in module name passed to
5039 imp.find_module() were converted to UTF-8 while the path is
5040 converted to the default filesystem encoding, causing nonsense.
5041
Benjamin Peterson09832742009-03-26 17:15:46 +00005042- Issue #5126: str.isprintable() returned False for space characters.
5043
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005044- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5045 the end sys.path, for compatibility with the system install of Python.
5046
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005047- Issue #4688: Add a heuristic so that tuples and dicts containing only
5048 untrackable objects are not tracked by the garbage collector. This can
5049 reduce the size of collections and therefore the garbage collection overhead
5050 on long-running programs, depending on their particular use of datatypes.
5051
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005052- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5055
Mark Dickinsonbd792642009-03-18 20:06:12 +00005056- Issue #4258: Make it possible to use base 2**30 instead of base
5057 2**15 for the internal representation of integers, for performance
5058 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5059 --enable-big-digits option to configure, which overrides the
5060 default. Add sys.int_info structseq to provide information about
5061 the internal format.
5062
Mark Dickinson081dfee2009-03-18 14:47:41 +00005063- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5064 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5065 and sizeof(Py_UNICODE) == 2.
5066
Eric Smith8ec90442009-03-14 12:29:34 +00005067- Issue #5237: Allow auto-numbered fields in str.format(). For
5068 example: '{} {}'.format(1, 2) == '1 2'.
5069
Antoine Pitrou652e7072009-03-13 19:25:20 +00005070- Issue #5392: when a very low recursion limit was set, the interpreter would
5071 abort with a fatal error after the recursion limit was hit twice.
5072
Matthias Klose042f1332009-04-04 14:32:42 +00005073- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
5074 short file names.
5075

R. David Murray548ac412009-04-02 19:44:43 +00005080 mailbox.MH.get_message().
5081
Hye-Shik Chang944820b2009-04-02 10:33:16 +00005082- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
5083 error substitutions from non-strict codec error callbacks in
5084 incrementalencoder and StreamWriter.
5085
Georg Brandl33c28812009-04-01 23:07:29 +00005086- Issue #5656: Fix the coverage reporting when running the test suite with

5104
Brett Cannon7f6b4f82009-03-30 21:30:26 +00005105- Issue #5236: Change time.strptime() to only take strings. Didn't work with
5106 bytes already but the failure was non-obvious.
5107
Jesse Noller7af4ef82009-03-30 16:47:15 +00005108- Issue #5177: Multiprocessing's SocketListener class now uses

5116
Benjamin Peterson59406a92009-03-26 17:10:29 +00005117- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
5118 io.BufferedRandom have been deprecated for removal in Python 3.2.
5119
Lars Gustäbel42e00912009-03-22 20:34:29 +00005120- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5121 forever on incomplete input. That caused tarfile.open() to hang when used
5122 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5123 partial bzip2 compressed data.
5124
Mark Dickinson79f52032009-03-17 23:12:51 +00005125- Issue #2110: Add support for thousands separator and 'n' type

5129 '>' alignment characters.
5130
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00005131- The error detection code in FileIO.close() could fail to reflect the `errno`
5132 value, and report it as -1 instead.
5133
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00005134- Issue #5016: FileIO.seekable() could return False if the file position

5141
Mark Dickinsonae681df2009-03-21 10:26:31 +00005142- Issue #5463: In struct module, remove deprecated overflow wrapping
5143 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005144 struct.error instead of returning b'\xff\xff\xff\xff'. The
5145 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5146 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005173- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5174 it now forces its argument to double before testing for infinity.
5175
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005176- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5177 returns a non-number type.
5178
Benjamin Peterson87618552009-02-08 15:00:52 +00005179- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005185
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005186- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005187 were suppressing all exceptions. These include list() and bytearray().
5188
Mark Dickinson1124e712009-01-28 21:25:58 +00005189- Issue #4707: round(x, n) now returns an integer if x is an integer.
5190 Previously it returned a float.

5193 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5194 evaluation loop is compiled with a new dispatch mechanism which gives
5195 speedups of up to 20%, depending on the system, on various benchmarks.

Georg Brandl65ce6ad2010-09-05 17:32:31 +00005208 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005209
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005210- Issue #4935: The overflow checking code in the expandtabs() method common
5211 to str, bytes and bytearray could be optimized away by the compiler, letting
5212 the interpreter segfault instead of raising an error.
5213
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005214- Issue #3720: Fix a crash when an iterator modifies its class and removes its

5226 common cases are optimized thanks to a dedicated fast path and a moderate
5227 amount of loop unrolling.
5228
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005229- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5230 collecting the oldest generation) so that allocating lots of objects without
5231 destroying them does not show quadratic performance. Based on a proposal by
5232 Martin von Löwis at
5233 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5234
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005235- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005236 having been closed (for instance, a read() call could return some
5237 previously buffered data). Patch by Dmitry Vasiliev.
5238
Antoine Pitrou05608432009-01-09 18:53:14 +00005239- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5240 flag to work properly. Furthermore, when specifying -u, the text stdout
5241 and stderr streams have line-by-line buffering enabled (the default being
5242 to buffer arbitrary chunks of data).
5243
Raymond Hettinger35631532009-01-09 03:58:09 +00005244- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5245 instead of ints (reducing its size from 4 to 8 times thereby reducing
5246 Python's overall memory).
5247
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005248- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5249 an existing .py counterpart, override the co_filename attributes of all
5250 code objects if the original filename is obsolete (which can happen if the
5251 file has been renamed, moved, or if it is accessed through different paths).
5252 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5253
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005254- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5255 one byte. Also fixes the meaning of len() so that it returns the number of
5256 items, rather than the size in bytes.
5257
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005258- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5259
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005260- Issue #4747: When the terminal does not use utf-8, executing a script with

5267 did not get collected.
5268
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005269- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5270 where the tp_hash and tp_dict slots are both NULL.
5271
Georg Brandlccc47b62008-12-28 11:44:14 +00005272- Issue #4759: None is now allowed as the first argument of
5273 bytearray.translate(). It was always allowed for bytes.translate().
5274
Skip Montanaro80072cb2008-12-23 03:51:14 +00005275- Added test case to ensure attempts to read from a file opened for writing
5276 fail.

5282
Antoine Pitrou621601a2008-12-17 23:18:19 +00005283- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5284 print elapsed times, not only when some objects are uncollectable /
5285 unreachable. Original patch by Neil Schemenauer.
5286

5288
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005289- Issue #2173: When getting device encoding, check that return value of
5290 nl_langinfo is not the empty string. This was causing silent build
5291 failures on OS X.
5292
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005293- Issue #4597: Fixed several opcodes that weren't always propagating
5294 exceptions.
5295
5296- Issue #4589: Fixed exception handling when the __exit__ function of a

5647 do an explicit seek to the end of file (so that e.g. tell() returns the

5679 appropriately when it is being used via socket.makefile() objects
5680 rather than delaying the close by waiting for garbage collection to do it.

5932 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
5933 the same behaviour as test_ttkguionly (and now also test_tk) which is to
5934 skip the tests if DISPLAY is defined but can't be used.

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00005937 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00005938 from test support, which does the conversion.
