Victor Stinnerca2b6462012-08-29 01:40:57 +020064- Issue #15785: Modify window.get_wch() API of the curses module: return
65 a character for most keys, and an integer for special keys, instead of
66 always returning an integer. So it is now possible to distinguish special
67 keys like keypad keys.
68
Victor Stinnereaaf9e92012-09-01 15:00:34 +020069- Issue #14223: Fix window.addch() of the curses module for special characters
70 like curses.ACS_HLINE: the Python function addch(int) and addch(bytes) is now
71 calling the C function waddch()/mvwaddch() (as it was done in Python 3.2),
72 instead of wadd_wch()/mvwadd_wch(). The Python function addch(str) is still
73 calling the C function wadd_wch()/mvwadd_wch() if the Python curses is linked
74 to libncursesw.

Ned Deilycbfb9a52012-06-23 16:02:19 -0700901- Issue #13590: Improve support for OS X Xcode 4:
902 * Try to avoid building Python or extension modules with problematic
903 llvm-gcc compiler.
904 * Since Xcode 4 removes ppc support, extension module builds now
905 check for ppc compiler support and automatically remove ppc and
906 ppc64 archs when not available.
907 * Since Xcode 4 no longer install SDKs in default locations,
908 extension module builds now revert to using installed headers
909 and libs if the SDK used to build the interpreter is not
910 available.
911 * Update ./configure to use better defaults for universal builds;
912 in particular, --enable-universalsdk=yes uses the Xcode default
913 SDK and --with-universal-archs now defaults to "intel" if ppc
914 not available.

Georg Brandl88b95f92012-05-06 11:24:06 +02001155 fields: st_ctime_ns, st_mtime_ns, and st_atime_ns, providing those times as an
1156 integer with nanosecond resolution. The functions os.utime(), os.lutimes(),
1157 and os.futimes() now accept a new parameter, ns, which accepts mtime and atime
1158 as integers with nanosecond resolution.
Larry Hastingsd9728b52012-05-05 21:57:17 -07001159

1685 (other than a bytes object).
1686
Antoine Pitrou6c40eb72012-01-18 20:16:09 +01001687- Issue #13521: dict.setdefault() now does only one lookup for the given key,

1691 suppressing the display of the chained exception context. The chained
1692 context still remains available as the __context__ attribute.
1693
Stefan Krah9a2d99e2012-02-25 12:24:21 +01001694- Issue #10181: New memoryview implementation fixes multiple ownership
1695 and lifetime issues of dynamically allocated Py_buffer members (#9990)
1696 as well as crashes (#8305, #7433). Many new features have been added
1697 (See whatsnew/3.3), and the documentation has been updated extensively.
1698 The ndarray test object from _testbuffer.c implements all aspects of
1699 PEP-3118, so further development towards the complete implementation
1700 of the PEP can proceed in a test-driven manner.
1701

1739
Gregory P. Smith9564e4c2012-01-21 14:50:11 -08001740- Issue #8052: The posix subprocess module would take a long time closing
1741 all possible file descriptors in the child process rather than just open
1742 file descriptors. It now closes only the open fds if possible for the
1743 default close_fds=True behavior.

1775
Antoine Pitroue0e27352011-12-15 14:31:28 +01001776- Fix OSError.__init__ and OSError.__new__ so that each of them can be

Ned Deily99377482012-02-10 13:01:08 +01002271- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2272 Distutils-based packages with C extension modules may fail because
2273 Apple has removed gcc-4.2, the version used to build python.org
2274 64-bit/32-bit Pythons. If the user does not explicitly override
2275 the default C compiler by setting the CC environment variable,
2276 Distutils will now attempt to compile extension modules with clang
2277 if gcc-4.2 is required but not found. Also as a convenience, if
2278 the user does explicitly set CC, substitute its value as the default
2279 compiler in the Distutils LDSHARED configuration variable for OS X.
2280 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2281 SDK, neither of which are available in Xcode 4. This change does not
2282 attempt to override settings to support their use with Xcode 4.)

2861 Condition, etc.) used to be factory functions returning instances of hidden
2862 classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this

3008
Ned Deily657b2de2011-06-28 19:51:30 -07003009- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3010 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3011 interpreter process. This could cause failures in non-Distutils subprocesses
3012 and was unreliable since tests or user programs could modify the interpreter
3013 environment after Distutils set it. Instead, have Distutils set the the
3014 deployment target only in the environment of each build subprocess. It is
3015 still possible to globally override the default by setting
3016 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3017 greater or equal to the default value, the value with which the interpreter

Nadeem Vawda3c01d162011-08-01 23:48:26 +02003835- Issue #11651: Improve the Makefile test targets to run more of the test suite
3836 more quickly. The --multiprocess option is now enabled by default, reducing
3837 the amount of time needed to run the tests. "make test" and "make quicktest"
3838 now include some resource-intensive tests, but no longer run the test suite
3839 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
Éric Araujo4f996442011-10-19 06:02:24 +02003840 an easy platform-independent way to run test suite with sensible defaults.

4149 files in binary mode, using the email package's binary support to parse

Steven Bethardb0270112011-01-24 21:02:50 +00004211
4212- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00004213 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

Georg Brandl4fbc0d82010-11-13 13:25:40 +00004971- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
4972 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00004973 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00004974 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00004975 encoding and to encode command line arguments on this OS.

4978 filenames encoded to the filesystem encoding with the surrogateescape error

5370 with a non-empty format string. This is an effort to future-proof user
5371 code. If a derived class does not currently implement __format__ but later
5372 adds its own __format__, it would most likely break user code that had

5374 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00005376- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
5377 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
5378 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 +00005380- Issue #9210: Configure option --with-wctype-functions was removed. Using the
5381 functions from the libc caused the methods .upper() and lower() to become

5389 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).

5393 Also, the "backslashreplace" error handler now joins surrogate pairs into a
5394 single character on UCS-2 builds.

Georg Brandl27a28582010-10-10 09:49:21 +00005431 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00005432 replacement for old handle_accept() and avoids the user to call accept()

Raymond Hettingerfa11db02010-09-12 04:12:42 +00005539- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00005540 it possible for the user to create self-referencing ordered dictionaries which
5541 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00005542 approach of using weakref proxies so that reference cycles never get created
5543 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00005549- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
5550 environment variable to set the filesystem encoding at Python startup.
5551 sys.setfilesystemencoding() creates inconsistencies because it is unable to
5552 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00005558- The pprint module now supports printing OrderedDicts in their given order

5563
Georg Brandl27a28582010-10-10 09:49:21 +00005564- Issue #9707: Rewritten reference implementation of threading.local which is
5565 friendlier towards reference cycles. This change is not normally visible
5566 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00005567
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00005568- Issue #6394: os.getppid() is now supported on Windows. Note that it will
5569 still return the id of the parent process after it has exited. This process
5570 id may even have been reused by another unrelated process.
5571
Georg Brandl27a28582010-10-10 09:49:21 +00005572- Issue #9792: In case of connection failure, socket.create_connection() would
5573 swallow the exception and raise a new one, making it impossible to fetch the
5574 original errno, or to filter timeout errors. Now the original error is
5575 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00005581- Updates to the random module:
5582
Georg Brandl27a28582010-10-10 09:49:21 +00005583 * Document which parts of the module are guaranteed to stay the same across
5584 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00005585
Georg Brandl27a28582010-10-10 09:49:21 +00005586 * Update the seed() method to use all of the bits in a string instead of just
5587 the hash value. This makes better use of the seed value and assures the
5588 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00005589
Georg Brandl27a28582010-10-10 09:49:21 +00005590 * Improved the random()-->integer algorithm used in choice(), shuffle(),
5591 sample(), randrange(), and randint(). Formerly, it used int(n*random())
5592 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00005593
5594 * Improved documentation of arguments to randrange(). Issue #9379.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00005609- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00005610 unsupported operation is attempted (for example, writing to a file open only

Gregory P. Smith13b55292010-09-06 08:30:23 +00005613- hashlib has two new constant attributes: algorithms_guaranteed and
5614 algorithms_avaiable that respectively list the names of hash algorithms
5615 guaranteed to exist in all Python implementations and the names of hash
5616 algorithms available in the current process.
5617
Brian Quinlanaf38dc52010-09-21 12:28:43 +00005618- A new package ``concurrent.futures`` as defined by PEP 3148.

5745 return characters from the full Unicode range, even on narrow unicode builds
5746 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

5748 large code points, and repr() may consider more characters as printable.

5775 use PyUnicode_FromFormatV() to format the warning message.

5783 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00005784
Georg Brandl649971e2010-09-05 17:06:50 +00005785- Issue #9416: Fix some issues with complex formatting where the output with no
5786 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00005787
5788 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Victor Stinner8182b712010-07-28 00:40:58 +00006121- Issue #8991: convertbuffer() rejects discontigious buffers.
6122
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00006123- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
6124 compiler.
6125
Benjamin Petersonccabcd42010-07-07 20:54:01 +00006126- Issue #8413: structsequence now subclasses tuple.
6127
Ezio Melotti57221d02010-07-01 07:32:02 +00006128- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00006129 start byte and the continuation byte(s) are now considered invalid, instead of
6130 the number of bytes specified by the start byte. E.g.:
6131 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
6132 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
6133 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
6134 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00006135
Georg Brandl62069d32010-07-31 08:56:11 +00006136- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
6137 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00006138
Benjamin Peterson88968ad2010-06-25 19:30:21 +00006139- Be more specific in error messages about positional arguments.
6140
Victor Stinner4aae1eb2010-06-24 22:08:25 +00006141- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
6142 objects, as described in the documentation.

Georg Brandl62069d32010-07-31 08:56:11 +00006148- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
6149 dealing with unary minus applied to a constant. The removed code was mutating
6150 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00006151
Victor Stinner554f3f02010-06-16 23:33:54 +00006152- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00006153 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00006154 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00006155 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00006156
Victor Stinner25e8ec42010-06-25 00:02:38 +00006157- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
6158 "w*" format instead. Add tests for "w*" format.
6159
Victor Stinner06e49dd2010-06-13 18:21:50 +00006160- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00006161 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00006162 string formats.
6163
Georg Brandl62069d32010-07-31 08:56:11 +00006164- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00006165 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
6166 location of the raised exception.
6167
Victor Stinner313a1202010-06-11 23:56:51 +00006168- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
6169 filenames and enable os.fsencode().
6170
Benjamin Peterson285a6892010-06-22 19:21:52 +00006171- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
6172
Georg Brandl62069d32010-07-31 08:56:11 +00006173- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
6174 interpreter with characters outside the Basic Multilingual Plane (higher than
6175 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00006176
Georg Brandl62069d32010-07-31 08:56:11 +00006177- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
6178 TypeError instead of giving a DeprecationWarning when a float is parsed using
6179 the 'L' code (for long long). (All other integer codes already raise
6180 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00006181
Victor Stinner600d3be2010-06-10 12:00:55 +00006182- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
6183 enable shortcuts for upper case encoding name. Add also a shortcut for
6184 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
6185
Georg Brandl62069d32010-07-31 08:56:11 +00006186- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
6187 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00006188
6189- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00006190 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00006191 like bytearray.
6192
Georg Brandl62069d32010-07-31 08:56:11 +00006193- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00006194 used anymore and it was never documented.
6195
Georg Brandl62069d32010-07-31 08:56:11 +00006196- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00006197
Georg Brandl62069d32010-07-31 08:56:11 +00006198- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
6199 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00006200
Georg Brandl62069d32010-07-31 08:56:11 +00006201- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
6202 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
6203 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
6204 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00006205
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00006206- Issue #8748: Fix two issues with comparisons between complex and integer
6207 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00006208 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
6209 (2) The comparison raised an OverflowError for large integers, leading to
6210 unpredictable exceptions when combining integers and complex objects in sets
6211 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00006212
Victor Stinner7d79b8b2010-05-19 20:40:50 +00006213- Issue #8766: Initialize _warnings module before importing the first module.
6214 Fix a crash if an empty directory called "encodings" exists in sys.path.
6215
Victor Stinner9ca9c252010-05-19 16:53:30 +00006216- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00006217 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00006218 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00006219
Georg Brandl62069d32010-07-31 08:56:11 +00006220- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
6221 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00006222
Victor Stinnerae6265f2010-05-15 16:27:27 +00006223- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
6224 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00006225 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00006226 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00006227
Victor Stinner59e62db2010-05-15 13:14:32 +00006228- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00006229 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00006230
Victor Stinnerb744ba12010-05-15 12:27:16 +00006231- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00006232 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00006233 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
6234
Victor Stinner0964ee12010-04-30 16:48:45 +00006235- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00006236 PyUnicode_FromString() to support surrogates in the filename and use the right
6237 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00006238
Georg Brandl8569e582010-05-19 20:57:08 +00006239- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
6240
Georg Brandl62069d32010-07-31 08:56:11 +00006241- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00006242
Benjamin Petersonfb886362010-04-24 18:21:17 +00006243- Issue #8419: Prevent the dict constructor from accepting non-string keyword
6244 arguments.
6245
Victor Stinner14284c22010-04-23 12:02:30 +00006246- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00006247 indirectly Python signal handlers anymore because mywrite() ignores exceptions
6248 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00006249
Victor Stinner31be90b2010-04-22 19:38:16 +00006250- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
Georg Brandl62069d32010-07-31 08:56:11 +00006251 unicode string (eg. backslashreplace).
Victor Stinner31be90b2010-04-22 19:38:16 +00006252
Georg Brandl62069d32010-07-31 08:56:11 +00006253- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
6254 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00006255
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00006256- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00006257 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
6258 compared to the dynamic memory allocation fallback. Patch by Charles-François
6259 Natali.

6337 crash in many places because of the PyByteArray_AS_STRING() macro returning
6338 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00006340- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00006341 where the right hand operand is a set of constants, by turning the set into a
6342 frozenset and pre-building it as a constant. The comparison operation is made
6343 against the constant instead of building a new set each time it is executed (a
6344 similar optimization already existed which turned a list of constants into a
6345 pre-built tuple). Patch and additional tests by Dave Malcolm.

6371 of integers: the result of a/b is now correctly rounded for ints a and b (at
6372 least on IEEE 754 platforms), and in particular does not depend on the
6373 internal representation of an int.

6649 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00006650 applications that use a lot of regular expressions and limits the impact of
6651 the performance hit anytime the cache is exceeded.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00007024 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00007025 relies on the system threading library, so as to avoid a semi-busy wait loop.

Georg Brandl62069d32010-07-31 08:56:11 +00007060- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
7061 InvalidOperation instead of returning False. (Comparisons involving a quiet
7062 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
7063 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00007065- Issue #2531: Comparison operations between floats and Decimal instances now
7066 return a result based on the numeric values of the operands; previously they
7067 returned an arbitrary result based on the relative ordering of id(float) and
7068 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
7069 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00007073- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00007074 argument `-` which tells it to read files to compile from stdin. Each line is
7075 read on demand and the named file is compiled immediately. (Original patch by
7076 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00007078- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00007082- Comparisons using one of <, <=, >, >= between a complex instance and a
7083 Fractions instance now raise TypeError instead of returning True/False. This
7084 makes Fraction <=> complex comparisons consistent with int <=> complex, float
7085 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00007128- The internals of the subprocess module on POSIX systems have been replaced by
7129 an extension module (_posixsubprocess) so that the fork()+exec() can be done
7130 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00007132- subprocess.Popen now has restore_signals and start_new_session features. The
7133 default of restore_signals=True is a new behavior compared to earlier Python
7134 versions. This means that signals such as SIGPIPE are not ignored by default
7135 in subprocesses launched by Python (Issue #1652).

7222 position when calling `truncate()`. It would previously change the file
7223 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00007224 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
7225
Antoine Pitroua32f9a22010-01-27 21:18:57 +00007226- Issue #7610: Reworked implementation of the internal
Georg Brandl88b95f92012-05-06 11:24:06 +02007227 ``zipfile.ZipExtFile`` class used to represent files stored inside an
Georg Brandl62069d32010-07-31 08:56:11 +00007228 archive. The new implementation is significantly faster and can be wrapped in
Georg Brandl88b95f92012-05-06 11:24:06 +02007229 a ``io.BufferedReader`` object for more speedups. It also solves an
Georg Brandl62069d32010-07-31 08:56:11 +00007230 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00007628- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00007629 compared to other unix systems. In particular, os.getgroups() does not reflect
7630 any changes made using os.setgroups() but basicly always returns the same
7631 information as the id command. os.getgroups() can now return more than 16
7632 groups on MacOSX.

Antoine Pitroue4501852009-05-14 18:55:55 +00008224- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
8225 library. This means, for example, that opening an UTF-16 text file in
8226 append mode doesn't add a BOM at the end of the file if the file isn't
8227 empty.
8228
R. David Murray74b89242009-05-13 17:33:03 +00008229- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
8230 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
8231 corrects a pydoc regression.
8232
Georg Brandl5f90d792010-08-01 22:31:05 +00008233- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00008234 now it does. This also means getfp method now returns the real fp.

8277Core and Builtins
8278-----------------
8279
Mark Dickinson865e01a2009-05-07 16:37:01 +00008280- Issue #5914: Add new C API function PyOS_string_to_double, and
8281 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
8282
Eric Smith741191f2009-05-06 13:08:15 +00008283- Issue #3382: float.__format__, complex.__format__, and %-formatting
8284 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
8285 affects nan -> NAN and inf -> INF.
8286
Mark Hammond5a607a32009-05-06 08:04:54 +00008287- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
8288 in all operations, including splitdrive, split, etc. splitunc() now issues
8289 a PendingDeprecation warning.
8290
Eric Smith63376222009-05-05 14:04:18 +00008291- Issue #5920: For float.__format__, change the behavior with the
8292 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
8293 to be like 'g' but with at least one decimal point and with a
8294 default precision of 12. Previously, the behavior the same but with
8295 a default precision of 6. This more closely matches str(), and
8296 reduces surprises when adding alignment flags to the empty
8297 presentation type. This also affects the new complex.__format__ in
8298 the same way.
8299
Martin v. Löwis011e8422009-05-05 04:43:17 +00008300- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
8301
R. David Murrayb18500d2009-05-04 22:59:07 +00008302- Issue #5890: in subclasses of 'property' the __doc__ attribute was
8303 shadowed by classtype's, even if it was None. property now
8304 inserts the __doc__ into the subclass instance __dict__.
8305
Antoine Pitrou244651a2009-05-04 18:56:13 +00008306- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
8307 sequences. Patch by Nick Barnes and Victor Stinner.
8308
Martin v. Löwise0a2b722009-05-10 08:08:56 +00008309- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00008310
Benjamin Petersond2e0c792009-05-01 20:40:59 +00008311- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
8312 received a new method, detach(). detach() disconnects the underlying stream
8313 from the buffer or text IO and returns it.
8314
Mark Dickinson33841c32009-05-01 15:37:04 +00008315- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
8316 floats with absolute value over 1e50. Also remove length
8317 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
8318 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00008319
Eric Smith741191f2009-05-06 13:08:15 +00008320- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00008321 format(complex(1, 2./3), '.5') now produces a sensible result.
8322
Mark Dickinsond3ca5572009-04-29 18:47:07 +00008323- Issue #5864: Fix empty format code formatting for floats so that it
8324 never gives more than the requested number of significant digits.
8325
Eric Smith6dc46f52009-04-27 20:39:49 +00008326- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
8327 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
8328
Eric Smithcc32a112009-04-26 21:35:14 +00008329- Issue #5835: Deprecate PyOS_ascii_formatd.
8330
Martin v. Löwis71efeb72009-04-26 01:02:07 +00008331- Issue #4971: Fix titlecase for characters that are their own
8332 titlecase, but not their own uppercase.
8333
Benjamin Peterson193152c2009-04-25 01:08:45 +00008334- Issue #5283: Setting __class__ in __del__ caused a segfault.
8335
Mark Dickinsonad476da2009-04-23 19:14:16 +00008336- Issue #5816: complex(repr(z)) now recovers z exactly, even when
8337 z involves nans, infs or negative zeros.
8338
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00008339- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00008340
Mark Dickinsone6a076d2009-04-18 11:48:33 +00008341- Issue #1869 (and many duplicates): make round(x, n) correctly
8342 rounded for a float x, by using the decimal <-> binary conversions
8343 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
8344 consistently agrees with format(x, '.2f').
8345
Benjamin Petersonae937c02009-04-18 20:54:08 +00008346- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
8347 some builtin types.
8348
Eric Smith0923d1d2009-04-16 20:16:10 +00008349- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
8350
Eric Smith35e84722009-04-16 20:21:28 +00008351- Issue #5515: str.format() type 'n' combined with commas and leading
8352 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00008353
8354- Implement PEP 378, Format Specifier for Thousands Separator, for
8355 floats.
8356
Mark Dickinson3370cce2009-04-17 22:40:53 +00008357- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008358 1e11, not 1e12. This avoids printing 13 significant digits in
8359 situations where only 12 of them are correct. Example problem
8360 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
8361 long time.)
8362
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008363- Issue #1580: On most platforms, use a 'short' float repr: for a
8364 finite float x, repr(x) now outputs a string based on the shortest
8365 sequence of decimal digits that rounds to x. Previous behaviour was
8366 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00008367 Another minor difference is that the new repr switches to
8368 exponential notation at 1e16 instead of the previous 1e17; this
8369 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008370
8371 There's a new sys attribute sys.float_repr_style, which takes
8372 the value 'short' to indicate that we're using short float repr,
8373 and 'legacy' if the short float repr isn't available for one
8374 reason or another.
8375
8376 The float repr change involves incorporating David Gay's 'perfect
8377 rounding' code into the Python core (it's in Python/dtoa.c). As a
8378 secondary consequence, all string-to-float and float-to-string
8379 conversions (including all float formatting operations) will be
8380 correctly rounded on these platforms.
8381
Georg Brandl5f90d792010-08-01 22:31:05 +00008382 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008383 this change does not apply.
8384
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00008385- Issue #5759: float() didn't call __float__ on str subclasses.
8386
Georg Brandlabc38772009-04-12 15:51:51 +00008387- The string.maketrans() function is deprecated; there is a new static method
8388 maketrans() on the bytes and bytearray classes. This removes confusion about
8389 the types string.maketrans() is supposed to work with, and mirrors the
8390 methods available on the str class.
8391
R. David Murraydc6da8a2009-04-09 22:16:43 +00008392- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
8393 its clarity and its speed.
8394
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008395- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00008396 to avoid compiler warnings.
8397
Walter Dörwald8dc33d52009-05-06 14:41:26 +00008398- Issue #3739: The unicode-internal encoder now reports the number of characters
8399 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00008536- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
8537
Benjamin Peterson7fe98532009-04-02 00:33:55 +00008538- Issue #5499: The 'c' code for argument parsing functions now only accepts a
8539 byte, and the 'C' code only accepts a unicode character.
8540
Georg Brandl406b3d82009-04-11 21:24:37 +00008541- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
8542 when hitting the recursion limit under certain circumstances.
8543
Brett Cannon0759dd62009-04-01 18:13:07 +00008544- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
8545
Georg Brandlab6f2f62009-03-31 04:16:10 +00008546- Fix a segfault when running test_exceptions with coverage, caused by
8547 insufficient checks in accessors of Exception.__context__.
8548
Guido van Rossum0ad59d42009-03-30 22:01:35 +00008549- Issue #5604: non-ASCII characters in module name passed to
8550 imp.find_module() were converted to UTF-8 while the path is
8551 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00008553- Issue #5126: str.isprintable() returned False for space characters.
8554
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00008555- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
8556 the end sys.path, for compatibility with the system install of Python.
8557
Antoine Pitrou3a652b12009-03-23 18:52:06 +00008558- Issue #4688: Add a heuristic so that tuples and dicts containing only
8559 untrackable objects are not tracked by the garbage collector. This can
8560 reduce the size of collections and therefore the garbage collection overhead
8561 on long-running programs, depending on their particular use of datatypes.
8562
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00008563- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

8568 2**15 for the internal representation of integers, for performance
8569 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
8570 --enable-big-digits option to configure, which overrides the
8571 default. Add sys.int_info structseq to provide information about
8572 the internal format.

8575 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
8576 and sizeof(Py_UNICODE) == 2.
8577
Eric Smith8ec90442009-03-14 12:29:34 +00008578- Issue #5237: Allow auto-numbered fields in str.format(). For

8580
Antoine Pitrou652e7072009-03-13 19:25:20 +00008581- Issue #5392: when a very low recursion limit was set, the interpreter would
8582 abort with a fatal error after the recursion limit was hit twice.
8583
Matthias Klose042f1332009-04-04 14:32:42 +00008584- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

8594 error substitutions from non-strict codec error callbacks in
8595 incrementalencoder and StreamWriter.
8596
Georg Brandl33c28812009-04-01 23:07:29 +00008597- Issue #5656: Fix the coverage reporting when running the test suite with

8615
Brett Cannon7f6b4f82009-03-30 21:30:26 +00008616- Issue #5236: Change time.strptime() to only take strings. Didn't work with
8617 bytes already but the failure was non-obvious.
8618
Jesse Noller7af4ef82009-03-30 16:47:15 +00008619- Issue #5177: Multiprocessing's SocketListener class now uses

8627
Benjamin Peterson59406a92009-03-26 17:10:29 +00008628- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
8629 io.BufferedRandom have been deprecated for removal in Python 3.2.
8630
Lars Gustäbel42e00912009-03-22 20:34:29 +00008631- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
8632 forever on incomplete input. That caused tarfile.open() to hang when used
8633 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
8634 partial bzip2 compressed data.
8635
Mark Dickinson79f52032009-03-17 23:12:51 +00008636- Issue #2110: Add support for thousands separator and 'n' type

8640 '>' alignment characters.
8641
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00008642- The error detection code in FileIO.close() could fail to reflect the `errno`
8643 value, and report it as -1 instead.

8652
Mark Dickinsonae681df2009-03-21 10:26:31 +00008653- Issue #5463: In struct module, remove deprecated overflow wrapping
8654 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00008655 struct.error instead of returning b'\xff\xff\xff\xff'. The
8656 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
8657 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00008684- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
8685 it now forces its argument to double before testing for infinity.
8686
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00008687- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
8688 returns a non-number type.
8689
Benjamin Peterson87618552009-02-08 15:00:52 +00008690- Issue #5182: Removed memoryview.__str__.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00008697- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00008698 were suppressing all exceptions. These include list() and bytearray().
8699
Mark Dickinson1124e712009-01-28 21:25:58 +00008700- Issue #4707: round(x, n) now returns an integer if x is an integer.
8701 Previously it returned a float.
8702
Antoine Pitroub52ec782009-01-25 16:34:23 +00008703- Issue #4753: By enabling a configure option named '--with-computed-gotos'
8704 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
8705 evaluation loop is compiled with a new dispatch mechanism which gives
8706 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00008721- Issue #4935: The overflow checking code in the expandtabs() method common
8722 to str, bytes and bytearray could be optimized away by the compiler, letting
8723 the interpreter segfault instead of raising an error.
8724
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00008725- Issue #3720: Fix a crash when an iterator modifies its class and removes its

8737 common cases are optimized thanks to a dedicated fast path and a moderate
8738 amount of loop unrolling.
8739
Antoine Pitrou14b78f52009-01-09 22:27:08 +00008740- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
8741 collecting the oldest generation) so that allocating lots of objects without
8742 destroying them does not show quadratic performance. Based on a proposal by

Antoine Pitrou8043cf82009-01-09 19:54:29 +00008747 having been closed (for instance, a read() call could return some
8748 previously buffered data). Patch by Dmitry Vasiliev.
8749
Antoine Pitrou05608432009-01-09 18:53:14 +00008750- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
8751 flag to work properly. Furthermore, when specifying -u, the text stdout
8752 and stderr streams have line-by-line buffering enabled (the default being
8753 to buffer arbitrary chunks of data).
8754
Raymond Hettinger35631532009-01-09 03:58:09 +00008755- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
8756 instead of ints (reducing its size from 4 to 8 times thereby reducing
8757 Python's overall memory).
8758
Antoine Pitroud35cbf62009-01-06 19:02:24 +00008759- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
8760 an existing .py counterpart, override the co_filename attributes of all
8761 code objects if the original filename is obsolete (which can happen if the
8762 file has been renamed, moved, or if it is accessed through different paths).
8763 Patch by Ziga Seilnacht and Jean-Paul Calderone.
8764
Antoine Pitrouc3b39242009-01-03 16:59:18 +00008765- Issue #4580: Fix slicing of memoryviews when the item size is greater than
8766 one byte. Also fixes the meaning of len() so that it returns the number of
8767 items, rather than the size in bytes.
8768
Martin v. Löwis5c88d812009-01-02 20:47:48 +00008769- Issue #4075: Use OutputDebugStringW in Py_FatalError.
8770
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00008771- Issue #4747: When the terminal does not use utf-8, executing a script with

8779
Nick Coghlanf1f2f682008-12-30 07:29:12 +00008780- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
8781 where the tp_hash and tp_dict slots are both NULL.
8782
Georg Brandlccc47b62008-12-28 11:44:14 +00008783- Issue #4759: None is now allowed as the first argument of
8784 bytearray.translate(). It was always allowed for bytes.translate().
8785
Skip Montanaro80072cb2008-12-23 03:51:14 +00008786- Added test case to ensure attempts to read from a file opened for writing
8787 fail.

9156
Antoine Pitrou08838b62009-01-21 00:55:13 +00009157- Issue #5008: When a file is opened in append mode with the new IO library,
9158 do an explicit seek to the end of file (so that e.g. tell() returns the

9190 appropriately when it is being used via socket.makefile() objects
9191 rather than delaying the close by waiting for garbage collection to do it.
9192
Raymond Hettingerb8baf632009-01-14 02:20:07 +00009193- Issue #1696199: Add collections.Counter() for rapid and convenient
