Antoine Pitrou11942a52011-11-28 19:08:36 +010020- Issue #7111: Python can now be run without a stdin, stdout or stderr
21 stream. It was already the case with Python 2. However, the corresponding
22 sys module entries are now set to None (instead of an unusable file object).
23
Antoine Pitrouf0effe62011-11-26 01:11:02 +010024- Issue #11849: Ensure that free()d memory arenas are really released

Victor Stinner6345be92011-11-25 20:09:01 +010029 different than "strict" anymore. The caller was unable to compute the
30 size of the output buffer: it depends on the error handler.
31
Antoine Pitrou86a36b52011-11-25 18:56:07 +010032- PEP 3155 / issue #13448: Qualified name for classes and functions.

41 to allow compiling extension modules with -Wswitch-enum on gcc.
42 Initial patch by Floris Bruynooghe.
43
Antoine Pitrouf34a0cd2011-11-18 20:14:34 +010044- Issue #10227: Add an allocation cache for a single slice object. Patch by
45 Stefan Behnel.
46
Antoine Pitrou56a220a2011-11-16 00:56:10 +010047- Issue #13393: BufferedReader.read1() now asks the full requested size to
48 the raw stream instead of limiting itself to the buffer size.
49
Antoine Pitrou28e401e2011-11-15 19:15:19 +010050- Issue #13392: Writing a pyc file should now be atomic under Windows as well.
51
Antoine Pitrou5418ee02011-11-15 01:42:21 +010052- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
53 already accepts them).
54
Antoine Pitrou9a812cb2011-11-15 00:00:12 +010055- Issue #13389: Full garbage collection passes now clear the freelists for
56 list and dict objects. They already cleared other freelists in the
57 interpreter.
58
Brian Curtin52fbea12011-11-06 13:41:17 -060059- Issue #13327: Remove the need for an explicit None as the second argument
Brian Curtin304a1652011-11-07 16:30:01 -060060 to os.utime, os.lutimes, os.futimes, os.futimens, os.futimesat, in
61 order to update to the current time. Also added keyword argument
62 handling to os.utimensat in order to remove the need for explicit None.

89 object identity).
90
Nick Coghlande31b192011-10-23 22:04:16 +100091- Issue #1294232: In a few cases involving metaclass inheritance, the

Ned Deily657b2de2011-06-28 19:51:30 -0700909- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
910 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
911 interpreter process. This could cause failures in non-Distutils subprocesses
912 and was unreliable since tests or user programs could modify the interpreter
913 environment after Distutils set it. Instead, have Distutils set the the
914 deployment target only in the environment of each build subprocess. It is
915 still possible to globally override the default by setting
916 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
917 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700918 was built. Also, implement the same handling in packaging.

1708 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
Éric Araujo4f996442011-10-19 06:02:24 +02001709 an easy platform-independent way to run test suite with sensible defaults.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002821 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002822 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002823 encoding and to encode command line arguments on this OS.

2826 filenames encoded to the filesystem encoding with the surrogateescape error

Brett Cannonbc2eff32010-09-19 21:39:02 +00003211- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the

Nick Coghlan37ee8502010-12-03 14:26:13 +00003214- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00003217- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3218 with a non-empty format string. This is an effort to future-proof user
3219 code. If a derived class does not currently implement __format__ but later
3220 adds its own __format__, it would most likely break user code that had
3221 supplied a format string. This will be changed to a DeprecationWaring in
3222 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00003224- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3225 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3226 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 +00003228- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3229 functions from the libc caused the methods .upper() and lower() to become
3230 locale aware and created subtly wrong results.
3231
Georg Brandl27a28582010-10-10 09:49:21 +00003232- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3233 non-ASCII byte in the format string.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003235- Issue #4617: Previously it was illegal to delete a name from the local
3236 namespace if it occurs as a free variable in a nested block. This limitation
3237 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3238
Georg Brandl27a28582010-10-10 09:49:21 +00003239- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3240 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3241 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3242 single character on UCS-2 builds.

3246 memoryview), and gain support for the context management protocol.
3247
Antoine Pitrou079ce542010-09-08 12:37:10 +00003248- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00003277- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003278 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003279 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003280 replacement for old handle_accept() and avoids the user to call accept()
3281 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003304- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00003305 retry the select() loop instead of bailing out. This is because select() can
3306 incorrectly report a socket as ready for reading (for example, if it received
3307 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003387- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003388 it possible for the user to create self-referencing ordered dictionaries which
3389 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003390 approach of using weakref proxies so that reference cycles never get created
3391 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00003396
Georg Brandl27a28582010-10-10 09:49:21 +00003397- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3398 environment variable to set the filesystem encoding at Python startup.
3399 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3400 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00003406- The pprint module now supports printing OrderedDicts in their given order
3407 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00003408
Vinay Sajip121a1c42010-09-08 10:46:15 +00003409- Logging: Added QueueHandler class to facilitate logging usage with
3410 multiprocessing.
3411
Georg Brandl27a28582010-10-10 09:49:21 +00003412- Issue #9707: Rewritten reference implementation of threading.local which is
3413 friendlier towards reference cycles. This change is not normally visible
3414 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003415
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003416- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3417 still return the id of the parent process after it has exited. This process
3418 id may even have been reused by another unrelated process.
3419
Georg Brandl27a28582010-10-10 09:49:21 +00003420- Issue #9792: In case of connection failure, socket.create_connection() would
3421 swallow the exception and raise a new one, making it impossible to fetch the
3422 original errno, or to filter timeout errors. Now the original error is
3423 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003425- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3426 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3427 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003429- Updates to the random module:
3430
Georg Brandl27a28582010-10-10 09:49:21 +00003431 * Document which parts of the module are guaranteed to stay the same across
3432 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003433
Georg Brandl27a28582010-10-10 09:49:21 +00003434 * Update the seed() method to use all of the bits in a string instead of just
3435 the hash value. This makes better use of the seed value and assures the
3436 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003437
Georg Brandl27a28582010-10-10 09:49:21 +00003438 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3439 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3440 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003441
3442 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00003447- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
3448 cases now also have assertWarns and assertWarnsRegexp methods to check that a
3449 given warning type was triggered by the code under test.

3593 return characters from the full Unicode range, even on narrow unicode builds
3594 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3595 in Python is that unicodedata.numeric() now returns the correct value for
3596 large code points, and repr() may consider more characters as printable.
3597
Victor Stinner6c00c142010-08-17 23:37:11 +00003598- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00003615 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3616 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00003622- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3623 use PyUnicode_FromFormatV() to format the warning message.

3631 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003632
Georg Brandl649971e2010-09-05 17:06:50 +00003633- Issue #9416: Fix some issues with complex formatting where the output with no
3634 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003635
3636 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3637 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Ezio Melotti57221d02010-07-01 07:32:02 +00003976- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003977 start byte and the continuation byte(s) are now considered invalid, instead of
3978 the number of bytes specified by the start byte. E.g.:
3979 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3980 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3981 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3982 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003984- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3985 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

3997 dealing with unary minus applied to a constant. The removed code was mutating
3998 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00004000- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00004001 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00004002 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00004003 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00004004
Victor Stinner25e8ec42010-06-25 00:02:38 +00004005- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

4007
Victor Stinner06e49dd2010-06-13 18:21:50 +00004008- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00004009 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00004010 string formats.
4011
Georg Brandl62069d32010-07-31 08:56:11 +00004012- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00004013 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
4014 location of the raised exception.
4015
Victor Stinner313a1202010-06-11 23:56:51 +00004016- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
4017 filenames and enable os.fsencode().
4018
Benjamin Peterson285a6892010-06-22 19:21:52 +00004019- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
4020
Georg Brandl62069d32010-07-31 08:56:11 +00004021- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
4022 interpreter with characters outside the Basic Multilingual Plane (higher than
4023 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00004024
Georg Brandl62069d32010-07-31 08:56:11 +00004025- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
4026 TypeError instead of giving a DeprecationWarning when a float is parsed using
4027 the 'L' code (for long long). (All other integer codes already raise
4028 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00004029
Victor Stinner600d3be2010-06-10 12:00:55 +00004030- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
4031 enable shortcuts for upper case encoding name. Add also a shortcut for
4032 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
4033
Georg Brandl62069d32010-07-31 08:56:11 +00004034- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
4035 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004036
4037- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00004038 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004039 like bytearray.
4040
Georg Brandl62069d32010-07-31 08:56:11 +00004041- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00004042 used anymore and it was never documented.
4043
Georg Brandl62069d32010-07-31 08:56:11 +00004044- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00004045
Georg Brandl62069d32010-07-31 08:56:11 +00004046- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
4047 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00004048
Georg Brandl62069d32010-07-31 08:56:11 +00004049- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
4050 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
4051 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
4052 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00004053
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004054- Issue #8748: Fix two issues with comparisons between complex and integer
4055 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004056 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4057 (2) The comparison raised an OverflowError for large integers, leading to
4058 unpredictable exceptions when combining integers and complex objects in sets
4059 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004060
Victor Stinner7d79b8b2010-05-19 20:40:50 +00004061- Issue #8766: Initialize _warnings module before importing the first module.
4062 Fix a crash if an empty directory called "encodings" exists in sys.path.
4063
Victor Stinner9ca9c252010-05-19 16:53:30 +00004064- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00004065 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00004066 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00004067
Georg Brandl62069d32010-07-31 08:56:11 +00004068- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
4069 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00004070
Victor Stinnerae6265f2010-05-15 16:27:27 +00004071- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
4072 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00004073 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00004074 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00004075
Victor Stinner59e62db2010-05-15 13:14:32 +00004076- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00004077 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00004078
Victor Stinnerb744ba12010-05-15 12:27:16 +00004079- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00004080 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00004081 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
4082
Victor Stinner0964ee12010-04-30 16:48:45 +00004083- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00004084 PyUnicode_FromString() to support surrogates in the filename and use the right
4085 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00004086
Georg Brandl8569e582010-05-19 20:57:08 +00004087- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
4088
Georg Brandl62069d32010-07-31 08:56:11 +00004089- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00004090
Benjamin Petersonfb886362010-04-24 18:21:17 +00004091- Issue #8419: Prevent the dict constructor from accepting non-string keyword
4092 arguments.
4093
Victor Stinner14284c22010-04-23 12:02:30 +00004094- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00004095 indirectly Python signal handlers anymore because mywrite() ignores exceptions
4096 (KeyboardInterrupt).

Victor Stinner31be90b2010-04-22 19:38:16 +00004100
Georg Brandl62069d32010-07-31 08:56:11 +00004101- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
4102 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00004103
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00004104- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00004105 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
4106 compared to the dynamic memory allocation fallback. Patch by Charles-François
4107 Natali.

Georg Brandl62069d32010-07-31 08:56:11 +00004498 applications that use a lot of regular expressions and limits the impact of
4499 the performance hit anytime the cache is exceeded.

4622 comparisons; all comparisons involving numeric types (bool, int, float,
4623 complex, Decimal, Fraction) should now act as expected.

Georg Brandl62069d32010-07-31 08:56:11 +00004908- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4909 InvalidOperation instead of returning False. (Comparisons involving a quiet
4910 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4911 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004913- Issue #2531: Comparison operations between floats and Decimal instances now
4914 return a result based on the numeric values of the operands; previously they
4915 returned an arbitrary result based on the relative ordering of id(float) and
4916 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4917 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004918
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004919- Added a subtract() method to collections.Counter().
4920
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004921- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004922 argument `-` which tells it to read files to compile from stdin. Each line is
4923 read on demand and the named file is compiled immediately. (Original patch by
4924 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004926- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004930- Comparisons using one of <, <=, >, >= between a complex instance and a
4931 Fractions instance now raise TypeError instead of returning True/False. This
4932 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4933 <=> complex, and complex <=> complex comparisons.

4941
Antoine Pitrou910bd512010-03-22 20:11:09 +00004942- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004943 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004976- The internals of the subprocess module on POSIX systems have been replaced by
4977 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4978 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004979
Georg Brandl62069d32010-07-31 08:56:11 +00004980- subprocess.Popen now has restore_signals and start_new_session features. The
4981 default of restore_signals=True is a new behavior compared to earlier Python
4982 versions. This means that signals such as SIGPIPE are not ignored by default
4983 in subprocesses launched by Python (Issue #1652).

5070 position when calling `truncate()`. It would previously change the file
5071 position to the given argument, which goes against the tradition of

5076 archive. The new implementation is significantly faster and can be wrapped in
5077 a :class:`io.BufferedReader` object for more speedups. It also solves an
5078 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005476- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005477 compared to other unix systems. In particular, os.getgroups() does not reflect
5478 any changes made using os.setgroups() but basicly always returns the same
5479 information as the id command. os.getgroups() can now return more than 16
5480 groups on MacOSX.

Antoine Pitroue4501852009-05-14 18:55:55 +00006072- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
6073 library. This means, for example, that opening an UTF-16 text file in
6074 append mode doesn't add a BOM at the end of the file if the file isn't
6075 empty.

6125Core and Builtins
6126-----------------
6127
Mark Dickinson865e01a2009-05-07 16:37:01 +00006128- Issue #5914: Add new C API function PyOS_string_to_double, and
6129 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6130
Eric Smith741191f2009-05-06 13:08:15 +00006131- Issue #3382: float.__format__, complex.__format__, and %-formatting
6132 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6133 affects nan -> NAN and inf -> INF.
6134
Mark Hammond5a607a32009-05-06 08:04:54 +00006135- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6136 in all operations, including splitdrive, split, etc. splitunc() now issues
6137 a PendingDeprecation warning.
6138
Eric Smith63376222009-05-05 14:04:18 +00006139- Issue #5920: For float.__format__, change the behavior with the
6140 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6141 to be like 'g' but with at least one decimal point and with a
6142 default precision of 12. Previously, the behavior the same but with
6143 a default precision of 6. This more closely matches str(), and
6144 reduces surprises when adding alignment flags to the empty
6145 presentation type. This also affects the new complex.__format__ in
6146 the same way.
6147
Martin v. Löwis011e8422009-05-05 04:43:17 +00006148- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6149
R. David Murrayb18500d2009-05-04 22:59:07 +00006150- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6151 shadowed by classtype's, even if it was None. property now
6152 inserts the __doc__ into the subclass instance __dict__.
6153
Antoine Pitrou244651a2009-05-04 18:56:13 +00006154- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6155 sequences. Patch by Nick Barnes and Victor Stinner.
6156
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006157- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006158
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006159- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6160 received a new method, detach(). detach() disconnects the underlying stream
6161 from the buffer or text IO and returns it.
6162
Mark Dickinson33841c32009-05-01 15:37:04 +00006163- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6164 floats with absolute value over 1e50. Also remove length
6165 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6166 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006167
Eric Smith741191f2009-05-06 13:08:15 +00006168- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006169 format(complex(1, 2./3), '.5') now produces a sensible result.
6170
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006171- Issue #5864: Fix empty format code formatting for floats so that it
6172 never gives more than the requested number of significant digits.
6173
Eric Smith6dc46f52009-04-27 20:39:49 +00006174- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6175 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6176
Eric Smithcc32a112009-04-26 21:35:14 +00006177- Issue #5835: Deprecate PyOS_ascii_formatd.
6178
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006179- Issue #4971: Fix titlecase for characters that are their own
6180 titlecase, but not their own uppercase.
6181
Benjamin Peterson193152c2009-04-25 01:08:45 +00006182- Issue #5283: Setting __class__ in __del__ caused a segfault.
6183
Mark Dickinsonad476da2009-04-23 19:14:16 +00006184- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6185 z involves nans, infs or negative zeros.
6186
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006187- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006188
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006189- Issue #1869 (and many duplicates): make round(x, n) correctly
6190 rounded for a float x, by using the decimal <-> binary conversions
6191 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6192 consistently agrees with format(x, '.2f').
6193
Benjamin Petersonae937c02009-04-18 20:54:08 +00006194- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6195 some builtin types.
6196
Eric Smith0923d1d2009-04-16 20:16:10 +00006197- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6198
Eric Smith35e84722009-04-16 20:21:28 +00006199- Issue #5515: str.format() type 'n' combined with commas and leading
6200 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006201
6202- Implement PEP 378, Format Specifier for Thousands Separator, for
6203 floats.
6204
Mark Dickinson3370cce2009-04-17 22:40:53 +00006205- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006206 1e11, not 1e12. This avoids printing 13 significant digits in
6207 situations where only 12 of them are correct. Example problem
6208 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6209 long time.)
6210
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006211- Issue #1580: On most platforms, use a 'short' float repr: for a
6212 finite float x, repr(x) now outputs a string based on the shortest
6213 sequence of decimal digits that rounds to x. Previous behaviour was
6214 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006215 Another minor difference is that the new repr switches to
6216 exponential notation at 1e16 instead of the previous 1e17; this
6217 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006218
6219 There's a new sys attribute sys.float_repr_style, which takes
6220 the value 'short' to indicate that we're using short float repr,
6221 and 'legacy' if the short float repr isn't available for one
6222 reason or another.
6223
6224 The float repr change involves incorporating David Gay's 'perfect
6225 rounding' code into the Python core (it's in Python/dtoa.c). As a
6226 secondary consequence, all string-to-float and float-to-string
6227 conversions (including all float formatting operations) will be
6228 correctly rounded on these platforms.
6229
Georg Brandl5f90d792010-08-01 22:31:05 +00006230 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006231 this change does not apply.
6232
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006233- Issue #5759: float() didn't call __float__ on str subclasses.
6234
Georg Brandlabc38772009-04-12 15:51:51 +00006235- The string.maketrans() function is deprecated; there is a new static method
6236 maketrans() on the bytes and bytearray classes. This removes confusion about
6237 the types string.maketrans() is supposed to work with, and mirrors the
6238 methods available on the str class.
6239
R. David Murraydc6da8a2009-04-09 22:16:43 +00006240- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6241 its clarity and its speed.
6242
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006243- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006244 to avoid compiler warnings.
6245
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006246- Issue #3739: The unicode-internal encoder now reports the number of characters
6247 consumed like any other encoder (instead of the number of bytes).

6385
Benjamin Peterson7fe98532009-04-02 00:33:55 +00006386- Issue #5499: The 'c' code for argument parsing functions now only accepts a
6387 byte, and the 'C' code only accepts a unicode character.
6388
Georg Brandl406b3d82009-04-11 21:24:37 +00006389- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
6390 when hitting the recursion limit under certain circumstances.
6391
Brett Cannon0759dd62009-04-01 18:13:07 +00006392- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
6393
Georg Brandlab6f2f62009-03-31 04:16:10 +00006394- Fix a segfault when running test_exceptions with coverage, caused by
6395 insufficient checks in accessors of Exception.__context__.
6396
Guido van Rossum0ad59d42009-03-30 22:01:35 +00006397- Issue #5604: non-ASCII characters in module name passed to
6398 imp.find_module() were converted to UTF-8 while the path is
6399 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00006401- Issue #5126: str.isprintable() returned False for space characters.
6402
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00006403- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
6404 the end sys.path, for compatibility with the system install of Python.
6405
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006406- Issue #4688: Add a heuristic so that tuples and dicts containing only
6407 untrackable objects are not tracked by the garbage collector. This can
6408 reduce the size of collections and therefore the garbage collection overhead
6409 on long-running programs, depending on their particular use of datatypes.
6410
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00006411- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

6423 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6424 and sizeof(Py_UNICODE) == 2.
6425
Eric Smith8ec90442009-03-14 12:29:34 +00006426- Issue #5237: Allow auto-numbered fields in str.format(). For

6428
Antoine Pitrou652e7072009-03-13 19:25:20 +00006429- Issue #5392: when a very low recursion limit was set, the interpreter would
6430 abort with a fatal error after the recursion limit was hit twice.
6431
Matthias Klose042f1332009-04-04 14:32:42 +00006432- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

6478
Lars Gustäbel42e00912009-03-22 20:34:29 +00006479- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6480 forever on incomplete input. That caused tarfile.open() to hang when used
6481 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6482 partial bzip2 compressed data.
6483
Mark Dickinson79f52032009-03-17 23:12:51 +00006484- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonae681df2009-03-21 10:26:31 +00006501- Issue #5463: In struct module, remove deprecated overflow wrapping
6502 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00006503 struct.error instead of returning b'\xff\xff\xff\xff'. The
6504 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

Mark Dickinson87ec0852009-02-09 17:15:59 +00006532- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6533 it now forces its argument to double before testing for infinity.
6534
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006535- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6536 returns a non-number type.
6537
Benjamin Peterson87618552009-02-08 15:00:52 +00006538- Issue #5182: Removed memoryview.__str__.

Raymond Hettingere8364232009-02-02 22:55:09 +00006546 were suppressing all exceptions. These include list() and bytearray().
6547
Mark Dickinson1124e712009-01-28 21:25:58 +00006548- Issue #4707: round(x, n) now returns an integer if x is an integer.
6549 Previously it returned a float.
6550

6552 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6553 evaluation loop is compiled with a new dispatch mechanism which gives
6554 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006569- Issue #4935: The overflow checking code in the expandtabs() method common
6570 to str, bytes and bytearray could be optimized away by the compiler, letting
6571 the interpreter segfault instead of raising an error.
6572
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006573- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou8043cf82009-01-09 19:54:29 +00006595 having been closed (for instance, a read() call could return some
6596 previously buffered data). Patch by Dmitry Vasiliev.
6597
Antoine Pitrou05608432009-01-09 18:53:14 +00006598- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6599 flag to work properly. Furthermore, when specifying -u, the text stdout
6600 and stderr streams have line-by-line buffering enabled (the default being
6601 to buffer arbitrary chunks of data).
6602
Raymond Hettinger35631532009-01-09 03:58:09 +00006603- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6604 instead of ints (reducing its size from 4 to 8 times thereby reducing
6605 Python's overall memory).
6606
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006607- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6608 an existing .py counterpart, override the co_filename attributes of all
6609 code objects if the original filename is obsolete (which can happen if the
6610 file has been renamed, moved, or if it is accessed through different paths).
6611 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6612
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006613- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6614 one byte. Also fixes the meaning of len() so that it returns the number of
6615 items, rather than the size in bytes.
6616
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006617- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6618
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006619- Issue #4747: When the terminal does not use utf-8, executing a script with

6627
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006628- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6629 where the tp_hash and tp_dict slots are both NULL.
6630
Georg Brandlccc47b62008-12-28 11:44:14 +00006631- Issue #4759: None is now allowed as the first argument of
6632 bytearray.translate(). It was always allowed for bytes.translate().
6633
Skip Montanaro80072cb2008-12-23 03:51:14 +00006634- Added test case to ensure attempts to read from a file opened for writing
6635 fail.

7004
Antoine Pitrou08838b62009-01-21 00:55:13 +00007005- Issue #5008: When a file is opened in append mode with the new IO library,
7006 do an explicit seek to the end of file (so that e.g. tell() returns the

7038 appropriately when it is being used via socket.makefile() objects
7039 rather than delaying the close by waiting for garbage collection to do it.
7040
Raymond Hettingerb8baf632009-01-14 02:20:07 +00007041- Issue #1696199: Add collections.Counter() for rapid and convenient
